a7effde99b MIPS: Kconfig: Use correct form for 'depends on'
Remove the CONFIG_ prefix from "depends on" as it makes the selection
not possible.

7d2aa4bb90 mips: Fix gettimeofday() in the vdso library
The libc provides a discovery mechanism for vDSO library and its
symbols. When a symbol is not exposed by the vDSOs the libc falls back
on the system calls.

With the introduction of the unified vDSO library on mips this behavior
is not honored anymore by the kernel in the case of gettimeofday().

The issue has been noticed and reported due to a dhclient failure on the
CI20 board:

root@letux:~# dhclient
../../../../lib/isc/unix/time.c:200: Operation not permitted
root@letux:~#

Restore the original behavior fixing gettimeofday() in the vDSO library.

9974406884 perf kvm: Clarify the 'perf kvm' -i and -o command line options
The 'perf kvm' subcommand has options that it in turn passes to other
perf subcommands such as 'report' and 'record', particularly -i and -o
end up setting the same variable that will then be used for 'record's -o
and report '-i', which ends up being confusing, leading some to think
that both -i and -o can be used with 'report'.

Improve the man page to state that -i is used with the post-processing
subcommands while -o is used just with 'record' and that to save the
output of 'report' one should simply redirect its output to a file.

Noticed while reading the https://www.linux-kvm.org/page/Perf_events
page.

f6661125ff perf beauty: Add CLEAR_SIGHAND support for clone's flags arg
Add support for the recently added CLONE_CLEAR_SIGHAND flag.

This takes advantage of the copy of the uapi/linux/sched.h we have in
tools/include, which allows us to build tools/perf in older systems and
have the binary support printing that flag whenever that system gets its
kernel updated to one where this feature is present.

6c3edaf9fd tracing: Introduce trace event injection
We have been trying to use rasdaemon to monitor hardware errors like
correctable memory errors. rasdaemon uses trace events to monitor
various hardware errors. In order to test it, we have to inject some
hardware errors, unfortunately not all of them provide error
injections. MCE does provide a way to inject MCE errors, but errors
like PCI error and devlink error don't, it is not easy to add error
injection to each of them. Instead, it is relatively easier to just
allow users to inject trace events in a generic way so that all trace
events can be injected.

This patch introduces trace event injection, where a new 'inject' is
added to each tracepoint directory. Users could write into this file
with key=value pairs to specify the value of each fields of the trace
event, all unspecified fields are set to zero values by default.

For example, for the net/net_dev_queue tracepoint, we can inject:

  INJECT=/sys/kernel/debug/tracing/events/net/net_dev_queue/inject
  echo "" > $INJECT
  echo "name='test'" > $INJECT
  echo "name='test' len=1024" > $INJECT
  cat /sys/kernel/debug/tracing/trace
  ...
   <...>-614   [000] ....    36.571483: net_dev_queue: dev= skbaddr=00000000fbf338c2 len=0
   <...>-614   [001] ....   136.588252: net_dev_queue: dev=test skbaddr=00000000fbf338c2 len=0
   <...>-614   [001] .N..   208.431878: net_dev_queue: dev=test skbaddr=00000000fbf338c2 len=1024

Triggers could be triggered as usual too:

  echo "stacktrace if len == 1025" > /sys/kernel/debug/tracing/events/net/net_dev_queue/trigger
  echo "len=1025" > $INJECT
  cat /sys/kernel/debug/tracing/trace
  ...
      bash-614   [000] ....    36.571483: net_dev_queue: dev= skbaddr=00000000fbf338c2 len=0
      bash-614   [001] ....   136.588252: net_dev_queue: dev=test skbaddr=00000000fbf338c2 len=0
      bash-614   [001] .N..   208.431878: net_dev_queue: dev=test skbaddr=00000000fbf338c2 len=1024
      bash-614   [001] .N.1   284.236349: <stack trace>
 => event_inject_write
 => vfs_write
 => ksys_write
 => do_syscall_64
 => entry_SYSCALL_64_after_hwframe

The only thing that can't be injected is string pointers as they
require constant string pointers, this can't be done at run time.

2603a4903b tools headers UAPI: Sync sched.h with the kernel

  fa729c4df5 ("clone3: validate stack arguments")
  b612e5df45 ("clone3: add CLONE_CLEAR_SIGHAND")

This file gets rebuilt, but no changes ensues:

   CC       /tmp/build/perf/trace/beauty/clone.o

This addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/sched.h' differs from latest version at 'include/uapi/linux/sched.h'
  diff -u tools/include/uapi/linux/sched.h include/uapi/linux/sched.

The CLONE_CLEAR_SIGHAND one will be used in tools/perf/trace/beauty/clone.c
in a followup patch to show that string when this bit is set in the
syscall arg. Keeping a copy of this file allows us to build this in
older systems and have the binary support printing that flag whenever
that system gets its kernel updated to one where this feature is
present.

which is caused by slab fault injection triggering a failure in
prepare_creds(). We don't actually need to create a copy of the creds
as we're not modifying it, we just need a reference on the current task
creds. This avoids the failure case as well, and propagates the const
throughout the stack.

Now it is possible to use these strings when setting up filters for the msr:*
tracepoints, like:

  # perf trace -e msr:* --filter=msr==IA32_TSX_CTRL
  ^C[root@quaco ~]#

If we use an invalid operator we can check what is the filter that is put in
place:

  # perf trace -e msr:* --filter=msr=IA32_TSX_CTRL
  Failed to set filter "(msr=0x122) && (common_pid != 25976 && common_pid != 25860)" on event msr:read_msr with 22 (Invalid argument)

One can as well use -v to see the tracepoints and its filters:

  # perf trace -v -e msr:* --filter=msr==IA32_TSX_CTRL
  Using CPUID GenuineIntel-6-8E-A
  New filter for msr:read_msr: (msr==0x122) && (common_pid != 26110 && common_pid != 25860)

3464afdf11 libbpf: Fix readelf output parsing on powerpc with recent binutils
On powerpc with recent versions of binutils, readelf outputs an extra

The extra "[<localentry>: 8]" prevents the GLOBAL_SYM_COUNT variable to
be computed correctly and causes the check_abi target to fail.

Fix that by looking for the symbol name in the last field instead of the

024aa8732a ACPI: PM: s2idle: Rework ACPI events synchronization
Note that the EC GPE processing need not be synchronized in
acpi_s2idle_wake() after invoking acpi_ec_dispatch_gpe(), because
that function checks the GPE status and dispatches its handler if
need be and the SCI action handler is not going to run anyway at
that point.

Moreover, it is better to drain all of the pending ACPI events
before restoring the working-state configuration of GPEs in
acpi_s2idle_restore(), because those events are likely to be related
to system wakeup, in which case they will not be relevant going
forward.

Rework the code to take these observations into account.

016b87ca5c ACPI: EC: Rework flushing of pending work
There is a race condition in the ACPI EC driver, between
__acpi_ec_flush_event() and acpi_ec_event_handler(), that may
cause systems to stay in suspended-to-idle forever after a wakeup
event coming from the EC.

Namely, acpi_s2idle_wake() calls acpi_ec_flush_work() to wait until
the delayed work resulting from the handling of the EC GPE in
acpi_ec_dispatch_gpe() is processed, and that function invokes
__acpi_ec_flush_event() which uses wait_event() to wait for
ec->nr_pending_queries to become zero on ec->wait, and that wait
queue may be woken up too early.

Suppose that acpi_ec_dispatch_gpe() has caused acpi_ec_gpe_handler()
to run, so advance_transaction() has been called and it has invoked
acpi_ec_submit_query() to queue up an event work item, so
ec->nr_pending_queries has been incremented (under ec->lock).  The
work function of that work item, acpi_ec_event_handler() runs later
and calls acpi_ec_query() to process the event.  That function calls
acpi_ec_transaction() which invokes acpi_ec_transaction_unlocked()
and the latter wakes up ec->wait under ec->lock, but it drops that
lock before returning.

When acpi_ec_query() returns, acpi_ec_event_handler() acquires
ec->lock and decrements ec->nr_pending_queries, but at that point
__acpi_ec_flush_event() (woken up previously) may already have
acquired ec->lock, checked the value of ec->nr_pending_queries (and
it would not have been zero then) and decided to go back to sleep.
Next, if ec->nr_pending_queries is equal to zero now, the loop
in acpi_ec_event_handler() terminates, ec->lock is released and
acpi_ec_check_event() is called, but it does nothing unless
ec_event_clearing is equal to ACPI_EC_EVT_TIMING_EVENT (which is
not the case by default).  In the end, if no more event work items
have been queued up while executing acpi_ec_transaction_unlocked(),
there is nothing to wake up __acpi_ec_flush_event() again and it
sleeps forever, so the suspend-to-idle loop cannot make progress and
the system is permanently suspended.

To avoid this issue, notice that it actually is not necessary to
wait for ec->nr_pending_queries to become zero in every case in
which __acpi_ec_flush_event() is used.

First, during platform-based system suspend (not suspend-to-idle),
__acpi_ec_flush_event() is called by acpi_ec_disable_event() after
clearing the EC_FLAGS_QUERY_ENABLED flag, which prevents
acpi_ec_submit_query() from submitting any new event work items,
so calling flush_scheduled_work() and flushing ec_query_wq
subsequently (in order to wait until all of the queries in that
queue have been processed) would be sufficient to flush all of
the pending EC work in that case.

Second, the purpose of the flushing of pending EC work while
suspended-to-idle described above really is to wait until the
first event work item coming from acpi_ec_dispatch_gpe() is
complete, because it should produce system wakeup events if
that is a valid EC-based system wakeup, so calling
flush_scheduled_work() followed by flushing ec_query_wq is also
sufficient for that purpose.

Rework the code to follow the above observations.

3b06ac6707 xen/gntdev: replace global limit of mapped pages by limit per call
Today there is a global limit of pages mapped via /dev/xen/gntdev set
to 1 million pages per default. There is no reason why that limit is
existing, as total number of grant mappings is limited by the
hypervisor anyway and preferring kernel mappings over userspace ones
doesn't make sense. It should be noted that the gntdev device is
usable by root only.

Additionally checking of that limit is fragile, as the number of pages
to map via one call is specified in a 32-bit unsigned variable which
isn't tested to stay within reasonable limits (the only test is the
value to be <= zero, which basically excludes only calls without any
mapping requested). So trying to map e.g. 0xffff0000 pages while
already nearly 1000000 pages are mapped will effectively lower the
global number of mapped pages such that a parallel call mapping a
reasonable amount of pages can succeed in spite of the global limit
being violated.

So drop the global limit and introduce per call limit instead. This
per call limit (default: 65536 grant mappings) protects against
allocating insane large arrays in the kernel for doing a hypercall
which will fail anyway in case a user is e.g. trying to map billions
of pages.

348be43384 xen/events: remove event handling recursion detection
__xen_evtchn_do_upcall() contains guards against being called
recursively. This mechanism was introduced in the early pvops times
(kernel 2.6.26) when there were all the Xen backend drivers missing
from the upstream kernel, and some of those out-of-tree drivers were
enabling interrupts in their event handlers (which was explicitly
allowed in the initial XenoLinux).

Nowadays we don't need to support those old drivers any more and the
capability to allow recursive calls of __xen_evtchn_do_upcall() can
be removed.

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.5 kernel cycle

  Core changes:

   - Expose pull up/down flags for the GPIO character device to
     userspace.

     After clear input from the RaspberryPi and Beagle communities, it
     has been established that prototyping, industrial automation and
     make communities strongly need this feature, and as we want people
     to use the character device, we have implemented the simple pull
     up/down interface for GPIO lines.

     This means we can specify that a (chip-specific) pull up/down
     resistor can be enabled, but does not offer fine-grained control
     such as cases where the resistance of the same pull resistor can be
     controlled (yet).

   - Introduce devm_fwnode_gpiod_get_index() and start to phase out the
     old symbol devm_fwnode_get_index_gpiod_from_child().

   - A bit of documentation clean-up work.

   - Introduce a define for GPIO line directions and deploy it in all
     GPIO drivers in the drivers/gpio directory.

   - Add a special callback to populate pin ranges when cooperating with
     the pin control subsystem and registering ranges as part of adding
     a gpiolib driver and a gpio_irq_chip driver at the same time. This
     is also deployed in the Intel Merrifield driver.

  New drivers:

   - RDA Micro GPIO controller.

   - XGS-iproc GPIO driver.

  Driver improvements:

   - Wake event and debounce support on the Tegra 186 driver.

   - Finalize the Aspeed SGPIO driver.

   - MPC8xxx uses a normal IRQ handler rather than a chained handler"

+ OCMEM support to enable the couple generations that had shared OCMEM
  rather than GMEM exclusively for the GPU (late a3xx and I think basically
  all of a4xx).  Bjorn and Brian decided to land this through the drm
  tree to avoid having to coordinate merge requests.
+ a510 support, and various associated display support
+ the usual misc cleanups and fixes
