d72cd4ad41 SCSI misc on 20210428 
This series consists of the usual driver updates (ufs, target, tcmu,
 smartpqi, lpfc, zfcp, qla2xxx, mpt3sas, pm80xx).  The major core
 change is using a sbitmap instead of an atomic for queue tracking.

35655ceb31 Here's a collection of largely clk driver updates for the merge window. The 
usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and
 Rockchip, but it feels pretty light on commits. There's only one real commit to
 the framework core and that's to consolidate code. Otherwise the diffstat is
 dominated by many Qualcomm clk driver patches that modernize the driver for the
 proper way of speciying clk parents. That's shifting data around, which could
 subtly break things so I'll be on the lookout for fixes.
 
 New Drivers:
  - Proper clk driver for Mediatek MT7621 SoCs
  - Support for the clock controller on the new Rockchip rk3568
 
 Updates:
  - Simplify Zynq Kconfig dependencies
  - Use clk_hw pointers in socfpga driver
  - Cleanup parent data in qcom clk drivers
  - Some cleanups for rk3399 modularization
  - Fix reparenting of i.MX UART clocks by initializing only the ones
    associated to stdout
  - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
  - Make i.MX LPCG and SCU clocks return on registering failure
  - Kernel doc fixes
  - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
  - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
  - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U
  - Sigma-delta modulation on Allwinner V3s audio PLL

Merge tag 'for-5.13/io_uring-2021-04-27' of git://git.kernel.dk/linux-block

Pull io_uring updates from Jens Axboe:

 - Support for multi-shot mode for POLL requests

 - More efficient reference counting. This is shamelessly stolen from
   the mm side. Even though referencing is mostly single/dual user, the
   128 count was retained to keep the code the same. Maybe this
   should/could be made generic at some point.

 - Removal of the need to have a manager thread for each ring. The
   manager threads only job was checking and creating new io-threads as
   needed, instead we handle this from the queue path.

 - Allow SQPOLL without CAP_SYS_ADMIN or CAP_SYS_NICE. Since 5.12, this
   thread is "just" a regular application thread, so no need to restrict
   use of it anymore.

 - Cleanup of how internal async poll data lifetime is managed.

 - Fix for syzbot reported crash on SQPOLL cancelation.

 - Make buffer registration more like file registrations, which includes
   flexibility in avoiding full set unregistration and re-registration.

 - Fix for io-wq affinity setting.

 - Be a bit more defensive in task->pf_io_worker setup.

 - Various SQPOLL fixes.

 - Cleanup of SQPOLL creds handling.

 - Improvements to in-flight request tracking.

 - File registration cleanups.

 - Tons of cleanups and little fixes

16b3d0cf5b Scheduler updates for this cycle are: 
- Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and debugfs interfaces
    to a unified debugfs interface.
 
  - Signals: Allow caching one sigqueue object per task, to improve performance & latencies.
 
  - Improve newidle_balance() irq-off latencies on systems with a large number of CPU cgroups.
 
  - Improve energy-aware scheduling
 
  - Improve the PELT metrics for certain workloads
 
  - Reintroduce select_idle_smt() to improve load-balancing locality - but without the previous
    regressions
 
  - Add 'scheduler latency debugging': warn after long periods of pending need_resched. This
    is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature,
    or the use of the resched_latency_warn_ms=xx boot parameter.
 
  - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix remaining
    balance_push() vs. hotplug holes/races
 
  - PSI fixes, plus allow /proc/pressure/ files to be written by CAP_SYS_RESOURCE tasks as well
 
  - Fix/improve various load-balancing corner cases vs. capacity margins
 
  - Fix sched topology on systems with NUMA diameter of 3 or above
 
  - Fix PF_KTHREAD vs to_kthread() race
 
  - Minor rseq optimizations
 
  - Misc cleanups, optimizations, fixes and smaller updates

42dec9a936 Perf events changes in this cycle were: 
- Improve Intel uncore PMU support:
 
      - Parse uncore 'discovery tables' - a new hardware capability enumeration method
        introduced on the latest Intel platforms. This table is in a well-defined PCI
        namespace location and is read via MMIO. It is organized in an rbtree.
 
        These uncore tables will allow the discovery of standard counter blocks, but
        fancier counters still need to be enumerated explicitly.
 
      - Add Alder Lake support
 
      - Improve IIO stacks to PMON mapping support on Skylake servers
 
  - Add Intel Alder Lake PMU support - which requires the introduction of 'hybrid' CPUs
    and PMUs. Alder Lake is a mix of Golden Cove ('big') and Gracemont ('small' - Atom derived)
    cores.
 
    The CPU-side feature set is entirely symmetrical - but on the PMU side there's
    core type dependent PMU functionality.
 
  - Reduce data loss with CPU level hardware tracing on Intel PT / AUX profiling, by
    fixing the AUX allocation watermark logic.
 
  - Improve ring buffer allocation on NUMA systems
 
  - Put 'struct perf_event' into their separate kmem_cache pool
 
  - Add support for synchronous signals for select perf events. The immediate motivation
    is to support low-overhead sampling-based race detection for user-space code. The
    feature consists of the following main changes:
 
     - Add thread-only event inheritance via perf_event_attr::inherit_thread, which limits
       inheritance of events to CLONE_THREAD.
 
     - Add the ability for events to not leak through exec(), via perf_event_attr::remove_on_exec.
 
     - Allow the generation of SIGTRAP via perf_event_attr::sigtrap, extend siginfo with an u64
       ::si_perf, and add the breakpoint information to ::si_addr and ::si_perf if the event is
       PERF_TYPE_BREAKPOINT.
 
    The siginfo support is adequate for breakpoints right now - but the new field can be used
    to introduce support for other types of metadata passed over siginfo as well.
 
  - Misc fixes, cleanups and smaller updates.

 new feature to support failure from dynamic analysis tools such as
 UBSAN and fake ops for testing.
 
 - a fake ops struct for testing a "free" function to complain if it
   was called with an invalid argument, or caught a double-free. Most

Merge tag 'printk-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
   result, the access to the buffer is fully lockless now.

   Note that printk() itself still uses locks because it tries to flush
   the messages to the console immediately. Also the per-CPU temporary
   buffers are still there because they prevent infinite recursion and
   serialize backtraces from NMI. All this is going to change in the
   future.

 - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
   removal.

 - Make bstr_printf() aware that %pf and %pF formats could deference the
   given pointer.

 - Show also page flags by %pGp format.

 - Clarify the documentation for plain pointer printing.

 - Do not show no_hash_pointers warning multiple times.

 - Update Senozhatsky email address.

 - Some clean up.

e7c6e405e1 Fix misc new gcc warnings 
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably
"-Wstringop-overread" and "-Warray-parameter".

Both of them cause what seem to be valid warnings in the kernel, where
we have array size mismatches in function arguments (that are no longer
just silently converted to a pointer to element, but actually checked).

This fixes most of the trivial ones, by making the function declaration
match the function definition, and in the case of intel_pm.c, removing
the over-specified array size from the argument declaration.

At least one 'stringop-overread' warning remains in the i915 driver, but
that one doesn't have the same obvious trivial fix, and may or may not
actually be indicative of a bug.

[ It was a mistake to upgrade one of my machines to Fedora 34 while
  being busy with the merge window, but if this is the extent of the
  compiler upgrade problems, things are better than usual    - Linus ]

   is working on a proper AppArmor patch, in the meantime this set of
   patches shouldn't change the behavior of AppArmor in any way. This
   change explains the bulk of the diffstat beyond security/.

Pull AFS updates from David Howells:
 "Use the new netfs lib.

  Begin the process of overhauling the use of the fscache API by AFS and
  the introduction of support for features such as Transparent Huge
  Pages (THPs).

   - Add some support for THPs, including using core VM helper functions
     to find details of pages.

   - Use the ITER_XARRAY I/O iterator to mediate access to the pagecache
     as this handles THPs and doesn't require allocation of large bvec
     arrays.

   - Delegate address_space read/pre-write I/O methods for AFS to the
     netfs helper library. A method is provided to the library that
     allows it to issue a read against the server.

     This includes a change in use for PG_fscache (it now indicates a
     DIO write in progress from the marked page), so a number of waits
     need to be deployed for it.

   - Split the core AFS writeback function to make it easier to modify
     in future patches to handle writing to the cache. [This might
     feasibly make more sense moved out into my fscache-iter branch].

  I've tested these with "xfstests -g quick" against an AFS volume
  (xfstests needs patching to make it work). With this, AFS without a
  cache passes all expected xfstests; with a cache, there's an extra
  failure, but that's also there before these patches. Fixing that
  probably requires a greater overhaul (as can be found on my
  fscache-iter branch, but that's for a later time).

  Thanks should go to Marc Dionne and Jeff Altman of AuriStor for
  exercising the patches in their test farm also"

Merge tag 'netfs-lib-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull network filesystem helper library updates from David Howells:
 "Here's a set of patches for 5.13 to begin the process of overhauling
  the local caching API for network filesystems. This set consists of
  two parts:

  (1) Add a helper library to handle the new VM readahead interface.

      This is intended to be used unconditionally by the filesystem
      (whether or not caching is enabled) and provides a common
      framework for doing caching, transparent huge pages and, in the
      future, possibly fscrypt and read bandwidth maximisation. It also
      allows the netfs and the cache to align, expand and slice up a
      read request from the VM in various ways; the netfs need only
      provide a function to read a stretch of data to the pagecache and
      the helper takes care of the rest.

  (2) Add an alternative fscache/cachfiles I/O API that uses the kiocb
      facility to do async DIO to transfer data to/from the netfs's
      pages, rather than using readpage with wait queue snooping on one
      side and vfs_write() on the other. It also uses less memory, since
      it doesn't do buffered I/O on the backing file.

      Note that this uses SEEK_HOLE/SEEK_DATA to locate the data
      available to be read from the cache. Whilst this is an improvement
      from the bmap interface, it still has a problem with regard to a
      modern extent-based filesystem inserting or removing bridging
      blocks of zeros. Fixing that requires a much greater overhaul.

  This is a step towards overhauling the fscache API. The change is
  opt-in on the part of the network filesystem. A netfs should not try
  to mix the old and the new API because of conflicting ways of handling
  pages and the PG_fscache page flag and because it would be mixing DIO
  with buffered I/O. Further, the helper library can't be used with the
  old API.

  This does not change any of the fscache cookie handling APIs or the
  way invalidation is done at this time.

  In the near term, I intend to deprecate and remove the old I/O API
  (fscache_allocate_page{,s}(), fscache_read_or_alloc_page{,s}(),
  fscache_write_page() and fscache_uncache_page()) and eventually
  replace most of fscache/cachefiles with something simpler and easier
  to follow.

  This patchset contains the following parts:

   - Some helper patches, including provision of an ITER_XARRAY iov
     iterator and a function to do readahead expansion.

   - Patches to add the netfs helper library.

   - A patch to add the fscache/cachefiles kiocb API.

   - A pair of patches to fix some review issues in the ITER_XARRAY and
     read helpers as spotted by Al and Willy.

  Jeff Layton has patches to add support in Ceph for this that he
  intends for this merge window. I have a set of patches to support AFS
  that I will post a separate pull request for.

  With this, AFS without a cache passes all expected xfstests; with a
  cache, there's an extra failure, but that's also there before these
  patches. Fixing that probably requires a greater overhaul. Ceph also
  passes the expected tests.

  I also have patches in a separate branch to tidy up the handling of
  PG_fscache/PG_private_2 and their contribution to page refcounting in
  the core kernel here, but I haven't included them in this set and will
  route them separately"

Pull CFI on arm64 support from Kees Cook:
 "This builds on last cycle's LTO work, and allows the arm64 kernels to
  be built with Clang's Control Flow Integrity feature. This feature has
  happily lived in Android kernels for almost 3 years[1], so I'm excited
  to have it ready for upstream.

  The wide diffstat is mainly due to the treewide fixing of mismatched
  list_sort prototypes. Other things in core kernel are to address
  various CFI corner cases. The largest code portion is the CFI runtime
  implementation itself (which will be shared by all architectures
  implementing support for CFI). The arm64 pieces are Acked by arm64
  maintainers rather than coming through the arm64 tree since carrying
  this tree over there was going to be awkward.

  CFI support for x86 is still under development, but is pretty close.
  There are a handful of corner cases on x86 that need some improvements
  to Clang and objtool, but otherwise works well.

  Summary:

   - Clean up list_sort prototypes (Sami Tolvanen)

   - Introduce CONFIG_CFI_CLANG for arm64 (Sami Tolvanen)"

4a0225c3d2 spi: Updates for v5.13 
The only core work for SPI this time around is the completion of the
 conversion to the new style method for specifying transfer delays,
 meaning we can cope with what most controllers support more directly
 using conversions in the core rather than open coding in drivers.
 Otherwise it's a good stack of cleanups and fixes plus a few new
 drivers.
 
 The conversion to new style transfer delay will cause an issue with a
 newly added staging driver which has a straightforward resolution in
 -next.
 
  - Completion of the conversion to new style transfer delay
    configuration.
  - Introduction and use of module_parport_driver() helper, merged here
    as there's no parport tree.
  - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
    MediaTek MT8195,

3d14ec1fe6 iov_iter: Four fixes for ITER_XARRAY 
Fix four things[1] in the patch that adds ITER_XARRAY[2]:

 (1) Remove the address_space struct predeclaration.  This is a holdover
     from when it was ITER_MAPPING.

 (2) Fix _copy_mc_to_iter() so that the xarray segment updates count and
     iov_offset in the iterator before returning.

 (3) Fix iov_iter_alignment() to not loop in the xarray case.  Because the
     middle pages are all whole pages, only the end pages need be
     considered - and this can be reduced to just looking at the start
     position in the xarray and the iteration size.

 (4) Fix iov_iter_advance() to limit the size of the advance to no more
     than the remaining iteration size.

   - make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags

   - export supported sectorsize values in sysfs (currently only page
     size, more once full subpage support lands)

   - more graceful errors and warnings on 32bit systems when logical
     addresses for metadata reach the limit posed by unsigned long in
     page::index
      - error: fail mount if there's a metadata block beyond the limit
      - error: new metadata block would be at unreachable address
      - warn when 5/8th of the limit is reached, for 4K page systems
        it's 10T, for 64K page it's 160T

   - zoned mode
      - relocated zones get reset at the end instead of discard
      - automatic background reclaim of zones that have 75%+ of unusable
        space, the threshold is tunable in sysfs

  Fixes:

   - fsync and tree mod log fixes

   - fix inefficient preemptive reclaim calculations

   - fix exhaustion of the system chunk array due to concurrent
     allocations

   - fix fallback to no compression when racing with remount

   - preemptive fix for dm-crypt on zoned device that does not properly
     advertise zoned support

  Core changes:

   - add inode lock to synchronize mmap and other block updates (eg.
     deduplication, fallocate, fsync)

   - kmap conversions to new kmap_local API

   - subpage support (continued)
      - new helpers for page state/extent buffer tracking
      - metadata changes now support read and write

   - error handling through out relocation call paths

   - many other cleanups and code simplifications"

0c85556318 ARM: platform support for Apple M1 
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 but it boots and can use framebuffer and serial console over a special
 USB cable.
 
 Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

f7857bf374 ARM: devicetree changes for 5.13 
There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450
 have separate branches because they are new SoC families that require
 changes outside of device tree files. The other four are variations of
 already supported chips and get merged through this branch:
 
  - STMicroelectronics STM32H750 is one of many variants of STM32
    microcontrollers based on the Cortex-M7 core. This is particularly
    notable since we rarely add support for new MMU-less chips
    these days. In this case, the board that gets added along with
    the platform is not a SoC reference platform but the "Art Pi"
    (https://art-pi.gitee.io/website/) machine that was originally design
    for the RT-Thread RTOS.
 
  - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial
    SoC family, using two Cortex-A72 and four Cortex-A53 cores. It
    gets added along with its reference board, the "NXP i.MX8QuadMax
    Multisensory Enablement Kit".
 
  - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c)
    that is used in some Chromebooks and Windows laptops. Only a reference
    board is added for the moment.
 
  - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial
    control, motor control, remote IO, IoT gateway etc., similar to the
    older AM65x family. Two reference machines are added alongside.
 
 Among the newly added machines, there is a very clear skew towards 64-bit
 machines now, with 12 32-bit machines compared to 23 64-bit machines. The
 full list sorted by SoC is:
 
  - ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
  - Allwinner A10: Topwise A721 Tablet
  - Amlogic GXL: MeCool KII TV box
  - Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
  - Broadcom BCM4908: TP-Link Archer C2300 V1 router
  - MStar SSD202D: M5Stack UnitV2 camera
  - Marvell Armada 38x: ATL-x530 ethernet switch
  - Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311,
    Asus Flip CM3, Asus Detachable CM3
  - Mediatek MT8516/MT8183: OLogic Pumpkin Board
  - NXP i.MX7: reMarkable Tablet
  - NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
  - Nuvoton NPCM730: Quanta GBS BMC
  - Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
  - Qualcomm MSM8998: OnePlus 5/5T phones
  - Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
  - Rockchip RK3399: NanoPi R4S board
  - STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM,
    EDIMM2.2 Starter Kit, Carrier, SOM
  - TI AM65: Siemens SIMATIC IOT2050 gateway
 
 There is notable work going into extending already supported machines
 and SoCs:
 
  - ASpeed AST2500
  - Allwinner A23, A83t, A31, A64, H6
  - Amlogic G12B
  - Broadcom BCM4908
  - Marvell Armada 7K/8K/CN91xx
  - Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
  - NXP i.MX8Q, i.MX8MM, i.MX8MP
  - Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
  - Renesas R-Car M3, V3U
  - Rockchip RK3328, RK3399
  - STEricsson U8500
  - STMicroelectronics STM32MP141
  - Samsung Exynos 4412
  - TI K3-AM65, K3-J7200
  - TI OMAP3
 
 Among the treewide cleanups and bug fixes, two parts stand out:
 
  - There are a number of cleanups for issues pointed out by 'make
    dtbs_check' this time, and I expect more to come in the future as we
    increasingly check for regressions.
 
  - After a change to the MMC subsystem that can lead to unpredictable
    device numbers, several platforms add 'aliases' properties for these
    to give each MMC controller a fixed number.

37f00ab4a0 ARM: SoC drivers for v5.13 
Updates for SoC specific drivers include a few subsystems that
 have their own maintainers but send them through the soc tree:
 
 TEE/OP-TEE:
  -  Add tracepoints around calls to secure world
 
 Memory controller drivers:
  - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
  - Add debug statistics to Tegra20 memory controller
  - Update Tegra bindings and convert to dtschema
 
 ARM SCMI Firmware:
  - Support for modular SCMI protocols and vendor specific extensions
  - New SCMI IIO driver
  - Per-cpu DVFS
 
 The other driver changes are all from the platform maintainers
 directly and reflect the drivers that don't fit into any other
 subsystem as well as treewide changes for a particular platform.
 
 SoCFPGA:
  - Various cleanups contributed by Krzysztof Kozlowski
 
 Mediatek:
  - add MT8183 support to mutex driver
  - MMSYS: use per SoC array to describe the possible routing
  - add MMSYS support for MT8183 and MT8167
  - add support for PMIC wrapper with integrated arbiter
  - add support for MT8192/MT6873
 
 Tegra:
  - Bug fixes to PMC and clock drivers
 
 NXP/i.MX:
  - Update SCU power domain driver to keep console domain power on.
  - Add missing ADC1 power domain to SCU power domain driver.
  - Update comments for single global power domain in SCU power domain
    driver.
  - Add i.MX51/i.MX53 unique id support to i.MX SoC driver.
 
 NXP/FSL SoC driver updates for v5.13
  - Add ACPI support for RCPM driver
  - Use generic io{read,write} for QE drivers after performance optimized
    for PowerPC
  - Fix QBMAN probe to cleanup HW states correctly for kexec
  - Various cleanup and style fix for QBMAN/QE/GUTS drivers
 
 OMAP:
  - Preparation to use devicetree for genpd
  - ti-sysc needs iorange check improved when the interconnect target module
    has no control registers listed
  - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
    issues with missing resources and unnecessary deferred probe
  - ti-sysc debug option can now detect more devices

Pull ARM SoC driver updates from Arnd Bergmann:
 "Updates for SoC specific drivers include a few subsystems that have
  their own maintainers but send them through the soc tree:

  TEE/OP-TEE:
   - Add tracepoints around calls to secure world

  Memory controller drivers:
   - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
   - Add debug statistics to Tegra20 memory controller

  ARM SCMI Firmware:
   - Support for modular SCMI protocols and vendor specific extensions
   - New SCMI IIO driver
   - Per-cpu DVFS

  The other driver changes are all from the platform maintainers
  directly and reflect the drivers that don't fit into any other
  subsystem as well as treewide changes for a particular platform.

  SoCFPGA:
   - Various cleanups contributed by Krzysztof Kozlowski

  Mediatek:
   - add MT8183 support to mutex driver
   - MMSYS: use per SoC array to describe the possible routing
   - add MMSYS support for MT8183 and MT8167

     avoid issues with missing resources and unnecessary deferred probe
   - ti-sysc debug option can now detect more devices
   - ti-sysc now warns if an old incomplete devicetree data is found as
     we now rely on it being complete for am3 and 4

     dra7
   - omap-prm driver needs to enable autoidle retention support for
     omap4

01d7136894 ARM: SoC changes for v5.13 
Almost all SoC code changes this time are for the TI OMAP
 platform, which continues its decade-long quest to move from
 describing a complex SoC in code to device tree.
 
 Aside from this, the Uniphier platform has a new maintainer
 and some platforms have minor bugfixes and cleanups that were
 not urgent enough for v5.12.

 over these drivers, as well as these "larger" changes:
 	- thunderbolt updates and new features added
 	- xhci driver updates and split out of a mediatek-specific xhci
 	  driver from the main xhci module to make it easier to work
 	  with (something that I have been wanting for a while).

d08410d8c9 TTY/Serial driver updates for 5.13-rc1 
Here is the big set of tty and serial driver updates for 5.13-rc1.
 
 Actually busy this release, with a number of cleanups happening:
 	- much needed core tty cleanups by Jiri Slaby
 	- removal of unused and orphaned old-style serial drivers.  If
 	  anyone shows up with this hardware, it is trivial to restore
 	  these but we really do not think they are in use anymore.
 	- fixes and cleanups from Johan Hovold on a number of termios
 	  setting corner cases that loads of drivers got wrong as well
 	  as removing unneeded code due to tty core changes from long
 	  ago that were never propagated out to the drivers
 	- loads of platform-specific serial port driver updates and
 	  fixes
 	- coding style cleanups and other small fixes and updates all
 	  over the tty/serial tree.
 
 All of these have been in linux-next for a while now with no reported
