platform/surface: aggregator: Allow notifiers to avoid communication on unregistering
When SSAM client devices have been (physically) hot-removed, communication attempts with those devices may fail and time out. This can even extend to event notifiers, due to which timeouts may occur during device removal, slowing down that process. Add a parameter to the notifier unregister function that allows skipping communication with the EC to prevent this. Furthermore, add wrappers for registering and unregistering notifiers belonging to SSAM client devices that automatically check if the device has been marked as hot-removed and communication should be avoided. Note that non-SSAM client devices can generally not be hot-removed, so also add a convenience wrapper for those, defaulting to allow communication.

platform/surface: aggregator: Allow devices to be marked as hot-removed
Some SSAM devices, notably the keyboard cover (keyboard and touchpad) on the Surface Pro 8, can be hot-removed. When this occurs, communication with the device may fail and time out. This timeout can unnecessarily block and slow down device removal and even cause issues when the devices are detached and re-attached quickly. Thus, communication should generally be avoided once hot-removal is detected. While we already remove a device as soon as we detect its (hot-)removal, the corresponding device driver may still attempt to communicate with the device during teardown. This is especially critical as communication failure may also extend to disabling of events, which is typically done at that stage. Add a flag to allow marking devices as hot-removed. This can then be used during client driver teardown to check if any communication attempts should be avoided.

platform/surface: aggregator: Allow is_ssam_device() to be used when CONFIG_SURFACE_AGGREGATOR_BUS is disabled
In SSAM subsystem drivers that handle both ACPI and SSAM-native client devices, we may want to check whether we have a SSAM (native) client device. Further, we may want to do this even when instantiation thereof cannot happen due to CONFIG_SURFACE_AGGREGATOR_BUS=n. Currently, doing so causes an error due to an undefined reference error due to ssam_device_type being placed in the bus source unit. Therefore, if CONFIG_SURFACE_AGGREGATOR_BUS is not defined, simply let is_ssam_device() return false to prevent this error.

hte: New subsystem for v5.19-rc1
This contains the new HTE subsystem that has been in the works for a couple of months now. The infrastructure provided allows for drivers to register as hardware timestamp providers, while consumers will be able to request events that they are interested in (such as GPIOs and IRQs) to be timestamped by the hardware providers. Note that this currently supports only one provider, but there seems to be enough interest in this functionality and we expect to see more drivers added once this is merged. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAmKZ77ATHHRyZWRpbmdA bnZpZGlhLmNvbQAKCRDdI6zXfz6zoTgVD/4tdJptbwblr8CCP5jklb81quuKBFu4 2VaUpyGo4TDD4g0jchmAkmB0JsjO7mauURZ/vwWUfDx+uvsOJyf79smY/4OvL0v6 MdYFeXb1rqDX8SiZSnpa+PKNI96l9/l1sbkbj1PPIod8hJSgXsASRP4lF21U97ZY QTI7u3kMJsUEvZhbEs9E2TXPAUO4+M8HfogJuEoaVRyHdwVHY1+Z+jlUsVXRd1qU XpIaKKMWF07FWrs2QUAbdqIUc8cITlcP+ExCc35PMwZnemWHnVwvk0mVyC0XD39P PHGlQOR2zTwJmijCwFkKTwuhGufE6bbvKvdns6gyTUlbzpQ4vcjPfVubt9ehX3dp acEJp5WdJFUhFU4dhjsLGVVzwE/L7vsZ3RPPh1j/Hjt0wYPg/EYPLr/wz+0wbIxt z4AtQZBLwrXSxXUuGkzl139kx0lTEtQZvfiziwi8BWrl6aqeBcGSNYHFLs2rDUTh sap+aEYRQ4cGWYfLMhv3yRLkkTlGxDMmEPM9VWGJb96osBcfidvgT+SE5qwoz6yg yJyMWwCrjYvYl+ZHwfKE3pEE4z9mrs7VLgcW9yWOF4UwFLuH0DyIEtCx/I4Uk+QG 7F1HuV3mYZNlOwgJMZooSJ5Z9uzrn+eGzivhw4klJibFZBXqICCQjL5KvQ8wyuY7 60Ns9+912HV/tQ== =sOJn -----END PGP SIGNATURE----- Merge tag 'hte/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux Pull hardware timestamping subsystem from Thierry Reding: "This contains the new HTE (hardware timestamping engine) subsystem that has been in the works for a couple of months now.

While looking at the ptrace problems with PREEMPT_RT and the problems
of Peter Zijlstra was encountering with ptrace in his freezer rewrite I identified some cleanups to ptrace_stop that make sense on their own and move make resolving the other problems much simpler. The biggest issue is the habbit of the ptrace code to change task->__state from the tracer to suppress TASK_WAKEKILL from waking up the tracee. No other code in the kernel does that and it is straight forward to update signal_wake_up and friends to make that unnecessary. Peter's task freezer sets frozen tasks to a new state TASK_FROZEN and then it stores them by calling "wake_up_state(t, TASK_FROZEN)" relying on the fact that all stopped states except the special stop states can tolerate spurious wake up and recover their state. The state of stopped and traced tasked is changed to be stored in task->jobctl as well as in task->__state. This makes it possible for the freezer to recover tasks in these special states, as well as serving as a general cleanup. With a little more work in that direction I believe TASK_STOPPED can learn to tolerate spurious wake ups and become an ordinary stop state. The TASK_TRACED state has to remain a special state as the registers for a process are only reliably available when the process is stopped in the scheduler. Fundamentally ptrace needs acess to the saved register values of a task. There are bunch of semi-random ptrace related cleanups that were found while looking at these issues. One cleanup that deserves to be called out is from commit |

These changes update the ipc sysctls so that they are fundamentally
per ipc namespace. Previously these sysctls depended upon a hack to simulate being per ipc namespace by looking up the ipc namespace in read or write. With this set of changes the ipc sysctls are registered per ipc namespace and open looks up the ipc namespace. Not only does this series of changes ensure the traditional binding at open time happens, but it sets a foundation for being able to relax the permission checks to allow a user namspace root to change the ipc sysctls for an ipc namespace that the user namespace root requires.

Add partial Loongarch architecture code
This is the majority of the loongarch architecture code, including
the final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so
it is currently impossible to boot the kernel, until the
loongarch specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
the MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the
PCI subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI
for the libc ports to build on, and to help any treewide changes
in the mainline kernel get applied here as well. A gcc-12 based
tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/.
Original description from Huacai Chen at
https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:
"LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
boot protocol LoongArch-specific interrupt controllers (similar to APIC)

Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
Note, I'm not really happy with this pull request as-is, see below for
details, but overall this is all good for everything but a small set of
systems, which we have a fix for already.
Lots of tiny driver core changes and cleanups happened this cycle,
but the two major things were:
- firmware_loader reorganization and additions including the
ability to have XZ compressed firmware images and the ability
for userspace to initiate the firmware load when it needs to,
instead of being always initiated by the kernel. FPGA devices
specifically want this ability to have their firmware changed
over the lifetime of the system boot, and this allows them to
work without having to come up with yet-another-custom-uapi
interface for loading firmware for them.
- physical location support added to sysfs so that devices that
know this information, can tell userspace where they are
located in a common way. Some ACPI devices already support
this today, and more bus types should support this in the
future.
Smaller changes included:
- driver_override api cleanups and fixes
- error path cleanups and fixes
- get_abi script fixes
- deferred probe timeout changes.
It's that last change that I'm the most worried about. It has been
reported to cause boot problems for a number of systems, and I have a
tested patch series that resolves this issue. But I didn't get it
merged into my tree before 5.18-final came out, so it has not gotten any
linux-next testing.
I'll send the fixup patches (there are 2) as a follow-on series to this
pull request if you want to take them directly, _OR_ I can just revert
the probe timeout changes and they can wait for the next -rc1 merge
cycle. Given that the fixes are tested, and pretty simple, I'm leaning
toward that choice. Sorry this all came at the end of the merge window,
I should have resolved this all 2 weeks ago, that's my fault as it was
in the middle of some travel for me.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time outs.

- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.

Merge tag 'tty-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty and serial driver updates from Greg KH:
"Here is the big set of tty and serial driver updates for 5.19-rc1.
Lots of tiny cleanups in here, the major stuff is:
- termbit cleanups and unification by Ilpo. A much needed change that
goes a long way to making things simpler for all of the different
arches
- tty documentation cleanups and movements to their own place in the
documentation tree
- old tty driver cleanups and fixes from Jiri to bring some existing
drivers into the modern world
- RS485 cleanups and unifications to make it easier for individual
drivers to support this mode instead of having to duplicate logic
in each driver
- Lots of 8250 driver updates and additions
- new device id additions
- n_gsm continued fixes and cleanups
- other minor serial driver updates and cleanups
All of these have been in linux-next for weeks with no reported issues"

nodemask: Fix return values to be unsigned

signed return values that could never happen. This was leading to the
compiler getting confusing about the range of possible return values

all the nodemask routines that should be returning unsigned
(or bool) values. Silences:

lib: add bitmap_{from,to}_arr64
Manipulating 64-bit arrays with bitmap functions is potentially dangerous
because on 32-bit BE machines the order of halfwords doesn't match.
Another issue is that compiler may throw a warning about out-of-boundary
access.
This patch adds bitmap_{from,to}_arr64 functions in addition to existing
bitmap_{from,to}_arr32.

lib/bitmap: extend comment for bitmap_(from,to)_arr32()
On LE systems bitmaps are naturally ordered, therefore we can potentially use bitmap_copy routines when converting from 32-bit arrays, even if host system is 64-bit. But it may lead to out-of-bond access due to unsafe typecast, and the bitmap_(from,to)_arr32 comment doesn't explain that clearly CC: Alexander Gordeev <agordeev@linux.ibm.com> CC: Andy Shevchenko <andriy.shevchenko@linux.intel.com> CC: Christian Borntraeger <borntraeger@linux.ibm.com> CC: Claudio Imbrenda <imbrenda@linux.ibm.com> CC: David Hildenbrand <david@redhat.com> CC: Heiko Carstens <hca@linux.ibm.com> CC: Janosch Frank <frankja@linux.ibm.com> CC: Rasmus Villemoes <linux@rasmusvillemoes.dk> CC: Sven Schnelle <svens@linux.ibm.com> CC: Vasily Gorbik <gor@linux.ibm.com> Signed-off-by: Yury Norov <yury.norov@gmail.com> |

drm/tegra: Preparatory work for v5.19
This contains a single patch from a series that's ready to go for v5.10 but is also a shared build-time dependency for an IOMMU series that is planned for v5.20.

ARM: multiplatform changes, part 2
The second part of the multiplatform changes now converts the Intel/Marvell PXA platform along with the rest. The patches went through several rebases before the merge window as bugs were found, so they remained separate. This has to touch a lot of drivers, in particular the touchscreen, pcmcia, sound and clk bits, to detach the driver files from the platform and board specific header files. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmKZKqsACgkQmmx57+YA GNnO/w//dgJBlkmoIIKlG2eJsvoUKwDt7MuLEMCqSqYYUSvMENFwKK66INMDIJ3l PmKf94JadlpBm2OB2vzW+D1EtaLGX9eXZkKD+vyB1I1yFkKdzEPcAfitfrRwe58E pR4nQd/jVL4UCY+pp442O1q9VvMpMV9P4ILJGPS/PpsD5CT9Gn8m9svIIuNuDRFd nwpyZC3l32jVLo9iuLmwZUvxtOWI3hTqZrnxhByBhlvtnGexRsq/VhfubK2uzBi1 CyWHjqzOSmseGmsUDwv9LFqVV9YRCeisS3IElA5L0VgM0XvHKA+f9qyF7V6zI20g y9LtqhdAtiTpE/aUrOW2LDYaM/bc7RilYZrWchoZbCEsHhV4C+ld3QoTyxvGscvG tbznhvZKdUNX8LHS0J9NqIj1q1YGN5ei5r/C5R8DBj1q8VcTVnq3dms8xzVTd35o xS5BbLFliiI96jc7S6LaQizXheYjAfdPhmXUAxNXvWIVQ6SXnf8/U/RB9Zzjb8hm FH2Gu8m/Dh2MHKBBRWSVw8VahV0V7WiEaWeYuwwTbW1wUrsWiizVaPnqrt6Cq9DW oJZgBvktWEXUQz73qrnvwo9GjcKqAxaWKWq05hHKHKuLGezsPAyIhIKr51V2xqqw cp2OIMCsN5GYENOhHvt6BMRAI5iA4VyFDtWAqw9B6EIwno6N7Z4= =cnSb -----END PGP SIGNATURE----- Merge tag 'arm-multiplatform-5.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull more ARM multiplatform updates from Arnd Bergmann: "The second part of the multiplatform changes now converts the Intel/Marvell PXA platform along with the rest.

delayacct: track delays from write-protect copy
Delay accounting does not track the delay of write-protect copy. When
tasks trigger many write-protect copys(include COW and unsharing of
anonymous pages[1]), it may spend a amount of time waiting for them. To
get the delay of tasks in write-protect copy, could help users to evaluate
the impact of using KSM or fork() or GUP.
Also update tools/accounting/getdelays.c:
/ # ./getdelays -dl -p 231
print delayacct stats ON

gpu: host1x: Add context bus
The context bus is a "dummy" bus that contains struct devices that correspond to IOMMU contexts assigned through Host1x to processes. Even when host1x itself is built as a module, the bus is registered in built-in code so that the built-in ARM SMMU driver is able to reference it.

Send along the already-allocated fattr along with nfs4_fs_locations, and
drop the memcpy of fattr. We end up growing two more allocations, but this

virtio: use WARN_ON() to warning illegal status value
We used to use BUG_ON() in virtio_device_ready() to detect illegal status value, this seems sub-optimal since the value is under the control of the device. Switch to use WARN_ON() instead.

virtio: harden vring IRQ
This is a rework on the previous IRQ hardening that is done for
virtio-pci where several drawbacks were found and were reverted:
1) try to use IRQF_NO_AUTOEN which is not friendly to affinity managed IRQ
that is used by some device such as virtio-blk
2) done only for PCI transport
The vq->broken is re-used in this patch for implementing the IRQ
hardening. The vq->broken is set to true during both initialization
and reset. And the vq->broken is set to false in
virtio_device_ready(). Then vring_interrupt() can check and return
when vq->broken is true. And in this case, switch to return IRQ_NONE
to let the interrupt core aware of such invalid interrupt to prevent
IRQ storm.
The reason of using a per queue variable instead of a per device one
is that we may need it for per queue reset hardening in the future.
Note that the hardening is only done for vring interrupt since the
config interrupt hardening is already done in commit

virtio: introduce config op to synchronize vring callbacks
This patch introduces new virtio config op to vring callbacks. Transport specific method is required to make sure the write before this function is visible to the vring_interrupt() that is called after the return of this function. For the transport that doesn't provide synchronize_vqs(), use synchornize_rcu() which synchronize with IRQ implicitly as a fallback.
