Add support for the CSUM_SEED feature which will allow future
userspace utilities to change the file system's UUID without rewriting all of the file system metadata. A number of miscellaneous fixes, the most significant of which are in the ext4 encryption support. Anyone wishing to use the encryption feature should backport all of the ext4 crypto patches up to 4.4 to get fixes to a memory leak and file system corruption bug. There are also cleanups in ext4's feature test macros and in ext4's sysfs support code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAABCAAGBQJWPMOAAAoJEPL5WVaVDYGjDYAH/jVIz+WpPkZn/J1Oepy1WPDm Azxv+tUvKffXQ7sRwGZEU7snLaeamKxtrvHUXKLT4PIQB6m6o4/kk8o71ovv5PRT FvuMz1j7qsqEk5ZFQnqI7xosao/RovjfkvL5g+WsAN//C+vxO35bg4fVvZmf73GQ vloe6igM/qxiUAuMX0jlXjUI1Zyo+H3bXOC6LjnUCOPwZMRcQ9zMtoYjkWryTzo1 4udepGRSfcWeZkWXqt9KIe6slYRmq3BtXWJ0+Zvx6gKWrXVIisINLDHYAEVBXAf4 6VUiDKL6wIytkwt3vGwYSY11wNQC5ky3qV/tJlPnpbYfUP0vEvT4UXljoaR/YQc= =m3Q9 -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: "Add support for the CSUM_SEED feature which will allow future userspace utilities to change the file system's UUID without rewriting all of the file system metadata.

PM / OPP: Protect updates to list_dev with mutex
dev_opp_list_lock is used everywhere to protect device and OPP lists, but dev_pm_opp_set_sharing_cpus() is missed somehow. And instead we used rcu-lock, which wouldn't help here as we are adding a new list_dev. This also fixes a problem where we have called kzalloc(..., GFP_KERNEL) from within rcu-lock, which isn't allowed as kzalloc can sleep when called with GFP_KERNEL. With CONFIG_DEBUG_ATOMIC_SLEEP set, we get following lockdep-splat: include/linux/rcupdate.h:578 Illegal context switch in RCU read-side critical section! other info that might help us debug this: rcu_scheduler_active = 1, debug_locks = 0 5 locks held by swapper/0/1: #0: (&dev->mutex){......}, at: [<c02f68f4>] __driver_attach+0x48/0x98 #1: (&dev->mutex){......}, at: [<c02f6904>] __driver_attach+0x58/0x98 #2: (cpu_hotplug.lock){++++++}, at: [<c00249d0>] get_online_cpus+0x40/0xb0 #3: (subsys mutex#5){+.+.+.}, at: [<c02f4f8c>] subsys_interface_register+0x44/0xdc #4: (rcu_read_lock){......}, at: [<c0305c80>] dev_pm_opp_set_sharing_cpus+0x0/0x1e4 stack backtrace: CPU: 1 PID: 1 Comm: swapper/0 Tainted: G W 4.3.0-rc7-00047-g81f5932958a8 #59 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c0016874>] (unwind_backtrace) from [<c001355c>] (show_stack+0x10/0x14) [<c001355c>] (show_stack) from [<c022553c>] (dump_stack+0x94/0xbc) [<c022553c>] (dump_stack) from [<c004904c>] (___might_sleep+0x24c/0x298) [<c004904c>] (___might_sleep) from [<c00f07e4>] (kmem_cache_alloc+0xe8/0x164) [<c00f07e4>] (kmem_cache_alloc) from [<c0305354>] (_add_list_dev+0x30/0x58) [<c0305354>] (_add_list_dev) from [<c0305d50>] (dev_pm_opp_set_sharing_cpus+0xd0/0x1e4) [<c0305d50>] (dev_pm_opp_set_sharing_cpus) from [<c040eda4>] (cpufreq_init+0x4cc/0x62c) [<c040eda4>] (cpufreq_init) from [<c040a964>] (cpufreq_online+0xbc/0x73c) [<c040a964>] (cpufreq_online) from [<c02f4fe0>] (subsys_interface_register+0x98/0xdc) [<c02f4fe0>] (subsys_interface_register) from [<c040a640>] (cpufreq_register_driver+0x110/0x17c) [<c040a640>] (cpufreq_register_driver) from [<c040ef64>] (dt_cpufreq_probe+0x60/0x8c) [<c040ef64>] (dt_cpufreq_probe) from [<c02f8084>] (platform_drv_probe+0x44/0xa4) [<c02f8084>] (platform_drv_probe) from [<c02f67c0>] (driver_probe_device+0x208/0x2f4) [<c02f67c0>] (driver_probe_device) from [<c02f6940>] (__driver_attach+0x94/0x98) [<c02f6940>] (__driver_attach) from [<c02f4c1c>] (bus_for_each_dev+0x68/0x9c) Reported-by: Michael Turquette <mturquette@baylibre.com> Reviewed-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: 4.3 <stable@vger.kernel.org> # 4.3 Signed-off-by: Rafael J.

um: Switch clocksource to hrtimers
UML is using an obsolete itimer call for all timers and "polls" for kernel space timer firing in its userspace portion resulting in a long list of bugs and incorrect behaviour(s). It also uses ITIMER_VIRTUAL for its timer which results in the timer being dependent on it running and the cpu load. This patch fixes this by moving to posix high resolution timers firing off CLOCK_MONOTONIC and relaying the timer correctly to the UML userspace. Fixes: - crashes when hosts suspends/resumes - broken userspace timers - effecive ~40Hz instead of what they should be. Note - this modifies skas behavior by no longer setting an itimer per clone(). Timer events are relayed instead. - kernel network packet scheduling disciplines - tcp behaviour especially under load - various timer related corner cases Finally, overall responsiveness of userspace is better.

Most of the changes are clean ups and small fixes. Some of them have
stable tags to them. I searched through my INBOX just as the merge window
opened and found lots of patches to pull. I ran them through all my tests
and they were in linux-next for a few days.
Features added this release:
----------------------------
o Module globbing. You can now filter function tracing to several
modules. # echo '*:mod:*snd*' > set_ftrace_filter (Dmitry Safonov)
o Tracer specific options are now visible even when the tracer is not
active. It was rather annoying that you can only see and modify tracer
options after enabling the tracer. Now they are in the options/ directory
even when the tracer is not active. Although they are still only visible
when the tracer is active in the trace_options file.
o Trace options are now per instance (although some of the tracer specific
options are global)
o New tracefs file: set_event_pid. If any pid is added to this file, then
all events in the instance will filter out events that are not part of
this pid. sched_switch and sched_wakeup events handle next and the wakee
pids.

perf test: Enhance the LLVM test: update basic BPF test program
This patch replaces the original toy BPF program with the previously
introduced bpf-script-example.c. Dynamically embeddeding it into
'llvm-src-base.c'.
The newly introduced BPF program attaches a BPF program to
'sys_epoll_pwait()'. perf itself never use that syscall, so further test
can verify their result with it. The program would generate 1 sample in
every 2 calls of epoll_pwait() system call.
Since the resulting BPF object is useful per se for further tests,
test_llvm__fetch_bpf_obj() is introduced for creating BPF objects from
source. The LLVM test was rewritten to use it.
Committer note:
Running it:

DeviceTree updates for 4.4:
- DT binding doc consolidation moving similar bindings to common
locations. The majority of these are display related which were
scattered in video/, fb/, drm/, gpu/, and panel/ directories.
- Add new config option, CONFIG_OF_ALL_DTBS, to enable building all dtbs
in the tree for most arches with dts files (except powerpc for now).
- OF_IRQ=n fixes for user enabled CONFIG_OF.
- of_node_put ref counting fixes from Julia Lawall.
- Common DT binding for wakeup-source and deprecation of all similar
bindings.
- DT binding for PXA LCD controller.
- Allow ignoring failed PCI resource translations in order to ignore
64-bit addresses on non-LPAE 32-bit kernels.
- Support setting the NUMA node from DT instead of only from parent
device.
- Couple of earlycon DT parsing fixes for address and options.

perf bpf: Improve BPF related error messages
A series of bpf loader related error codes were introduced to help error
reporting. Functions were improved to return these new error codes.
Functions which return pointers were adjusted to encode error codes into
return value using the ERR_PTR() interface.
bpf_loader_strerror() was improved to convert these error messages to
strings. It checks the error codes and calls libbpf_strerror() and
strerror_r() accordingly, so caller don't need to consider checking the
range of the error code.
In bpf__strerror_load(), print kernel version of running kernel and the
object's 'version' section to notify user how to fix his/her program.
v1 -> v2:
Use macro for error code.
Fetch error message based on array index, eliminate for-loop.
Print version strings.
Before:
# perf record -e ./test_kversion_nomatch_program.o sleep 1
event syntax error: './test_kversion_nomatch_program.o'
\___ Failed to load program: Validate your program and check 'license'/'version' sections in your object
SKIP
After:
# perf record -e ./test_kversion_nomatch_program.o ls
event syntax error: './test_kversion_nomatch_program.o'
\___ 'version' (4.4.0) doesn't match running kernel (4.3.0)

MTD updates for 4.4-rc1:
Core
* WARN (in some cases) when a struct mtd_info is registered multiple times;
in the past this was "supported", but it's still error prone for future
development. There's only one ugly case of this left in the tree (that
we're aware of) and the owners are aware of the problems there.
* fix potential deadlock in the blkdev removal path
NOTE: the (potential) deadlock was introduced in a for-stable patch. This
one is also marked for -stable.
* ioctl(BLKPG) compat_ioctl support; resolves issues with 32-bit user space
vs. 64-bit kernel space
* Set MTD parent device correctly throughout the tree, so the tree structure
appears correctly in sysfs; many drivers were missing this (soft)
requirement
* Move device tree partitions (ofpart) into a dedicated 'partitions' subnode;
this helps to disambiguate whether a node is a partition or some other
auxiliary data
* Improve error handling for partitioning failures
NAND
* General: Increase timeout period, for corner-case systems with
less-than-accurate jiffies
* Fix OF-based autoloading of several NAND drivers when built as modules
* pxa3xx_nand:
- Rework timing configuration to be more dynamic
- Refactor PM support
* brcmnand: prepare for NorthStar 2 support (ARM64, 16-bit NAND chips)
* sunxi_nand: refactoring and a few bug fixes
* vf610: new NAND driver
* FSMC: add SW BCH support; support common NAND DT bindings
* lpc32xx_slc: refactor and improve timing calculations logic
* denali: support for rev 5.1
SPI NOR
* Layering improvements
* Added Winbond lock/unlock support
* Added mtd_is_locked() (i.e., ioctl(MEMISLOCKED)) support
* Increase full-chip-erase timeout linearly with flash size
* fsl-quadspi: fix compile for non-ARM architectures
* New flash support

sound updates for 4.4-rc1
Here is the first batch of updates for sound system on 4.4-rc1.
Again at this time, the update looks fairly calm; no big changes in
either ALSA core or ASoC infrastructures, rather all small cleanups,
in addition to the new stuff as usual.
The biggest changes are about Firewire sound devices. It gained lots
of new device support, and MIDI functionality. Also there are updates
for a few still working-in-progress stuff (topology API and ASoC
skylake), too. But overall, this update should give no big surprise.
Some highlight is below:
Core:
- A few more Kconfig items for tinification; it's marked as EXPERT,
so normal user should't be bothered :)
- Refactoring with a new PCM hw_constraint helper
- Removal of unused transfer_ack_{begin,end} PCM callbacks
Firewire:
- Restructuring of code subtree, lots of refactoring
- Support AMDTP variants
- New driver for Digidesign 002/003 family
- Adds support for TASCAM FireOne to ALSA OXFW driver
- Add MIDI support to TASCAM and Digi00x devices
HD-Audio:
- Automated modalias generation for codec drivers, finally
- Improvement on heuristics for setting mixer name
- A few fixes for longstanding bugs on Creative CA0132 cards
- Addition of audio rate callback with i915 communication
- Fix suspend issue on recent Dell XPS
- Intel Lewisburg controller support
ASoC:
- Updates to the topology userspace interface
- Big updates to the Renesas support (rcar)
- More updates for supporting Intel Sky Lake systems
- New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
S/PDIF, and Atmel class D amplifier
USB-Audio:
- A fix for newer Roland MIDI devices
- Quirks and workarounds for Zoom R16/24 device
Misc:
- A few fixes for some old Cirrus CS46xx PCI sound boards
- Yet another fixes for some old ESS Maestro3 PCI sound boards

bpf tools: Improve libbpf error reporting
In this patch, a series of libbpf specific error numbers and
libbpf_strerror() are introduced to help reporting errors.
Functions are updated to pass correct the error number through the
CHECK_ERR() macro.
All users of bpf_object__open{_buffer}() and bpf_program__title() in
perf are modified accordingly. In addition, due to the error codes
changing, bpf__strerror_load() is also modified to use them.
bpf__strerror_head() is also changed accordingly so it can parse libbpf
errors. bpf_loader_strerror() is introduced for that purpose, and will
be improved by the following patch.
load_program() is improved not to dump log buffer if it is empty. log
buffer is also used to deduce whether the error was caused by an invalid
program or other problem.
v1 -> v2:
- Using macro for error code.
- Fetch error message based on array index, eliminate for-loop.
- Use log buffer to detect the reason of failure. 3 new error code

thinkpad_acpi: Don't yell on unsupported brightness interfaces
The thinkpad_acpi driver currently emits error messages on unsupported brightness interfaces, giving the impression that someone will implement those. However, this error is spit out on nearly every thinkpad in production since 2 years now. Furthermore, the backlight interfaces on those devices are supported by the i915 driver just fine. Downgrade the error message to a normal pr_info() and stop telling people to report it to IBM.
