Looks like the new generation of Lenovo machine also need to
be added to the PnPID whitelist. This is definitively not going
to scale, as there is nothing that tells us currently if a
touchpad supports a true physical middle button.
Consider that all new touchpads that are not clickpads
(so matching ETP_NEW_IC_SMBUS_HOST_NOTIFY) are handling 3 physical
buttons.

In the case of compat syscall ioctl numbers for UI_BEGIN_FF_UPLOAD and
UI_END_FF_UPLOAD need to be adjusted before being passed on
uinput_ioctl_handler() since code built with -m32 will be passing
slightly different values. Extend the code already covering
UI_SET_PHYS to cover UI_BEGIN_FF_UPLOAD and UI_END_FF_UPLOAD as well.

For systems in which the touch IRQ is acting as wakeup source, and that do
not support level-driven interrupts, the interrupt controller might not
latch the GPIO IRQ during sleep. In such cases, the interrupt will never
occur again after resume, hence the touch screen appears dead.
To fix this, check for the assertion of the attn gpio, and read form the
controller once in the resume path to read the hardware status and
to arm the IRQ again.
Introduce a mutex to guard eeti_ts_read() against parallel invocations
from different contexts.

New race in x86_pmu_stop() was introduced by replacing the
atomic __test_and_clear_bit() of cpuc->active_mask by separate
test_bit() and __clear_bit() calls in the following commit:
3966c3feca3f ("x86/perf/amd: Remove need to check "running" bit in NMI handler")
The race causes panic for PEBS events with enabled callchains:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000000
...
RIP: 0010:perf_prepare_sample+0x8c/0x530

...
The event is configured to make samples from PEBS drain code,
but when it's disabled, we'll go through NMI path instead,
where data->callchain will not get allocated and we'll crash:
x86_pmu_stop
test_bit(hwc->idx, cpuc->active_mask)
intel_pmu_disable_event(event)
{
...
intel_pmu_pebs_disable(event);
...

TEST PASSES -> test_bit(bit, cpuc->active_mask))
perf_event_overflow
perf_prepare_sample

...
if (!(sample_type & __PERF_SAMPLE_CALLCHAIN_EARLY))
data->callchain = perf_callchain(event, regs);
CRASH -> size += data->callchain->nr;
}
</NMI>
...
x86_pmu_disable_event(event)
}
__clear_bit(hwc->idx, cpuc->active_mask);
Fixing this by disabling the event itself before setting
off the PEBS bit.

This recent commit:
5768402fd9c6e87 ("perf/ring_buffer: Use high order allocations for AUX buffers optimistically")
overlooked the fact that the previous one page granularity of the AUX buffer
provided an implicit double buffering capability to the PMU driver, which
went away when the entire buffer became one high-order page.
Always make the full-trace mode AUX allocation at least two-part to preserve
the previous behavior and allow the implicit double buffering to continue.

Since those were introduced in:
c8ce48f06503 ("asm-generic: Make time32 syscall numbers optional")
But when the asm-generic/unistd.h was sync'ed with tools/ in:
1a787fc5ba18 ("tools headers uapi: Sync copy of asm-generic/unistd.h with the kernel sources")
I forgot to copy the files for the architectures that define
__ARCH_WANT_TIME32_SYSCALLS, so the perf build was breaking there, as
reported by Vineet Gupta for the ARC architecture.
After updating my ARC container to use the glibc based toolchain + cross
building libnuma, zlib and elfutils, I finally managed to reproduce the
problem and verify that this now is fixed and will not regress as will
be tested before each pull req sent upstream.

Thomas Backlund reported that the perf build was failing on the Mageia 7
distro, that is because it uses:
cat /tmp/build/perf/feature/test-disassembler-four-args.make.output
/usr/bin/ld: /usr/lib64/libbfd.a(plugin.o): in function `try_load_plugin':
/home/iurt/rpmbuild/BUILD/binutils-2.32/objs/bfd/../../bfd/plugin.c:243:
undefined reference to `dlopen'
/usr/bin/ld:
/home/iurt/rpmbuild/BUILD/binutils-2.32/objs/bfd/../../bfd/plugin.c:271:
undefined reference to `dlsym'
/usr/bin/ld:
/home/iurt/rpmbuild/BUILD/binutils-2.32/objs/bfd/../../bfd/plugin.c:256:
undefined reference to `dlclose'
/usr/bin/ld:
/home/iurt/rpmbuild/BUILD/binutils-2.32/objs/bfd/../../bfd/plugin.c:246:
undefined reference to `dlerror'
as we allow dynamic linking and loading
Mageia 7 uses these linker flags:
$ rpm --eval %ldflags
-Wl,--as-needed -Wl,--no-undefined -Wl,-z,relro -Wl,-O1 -Wl,--build-id -Wl,--enable-new-dtags
So add -ldl to this feature LDFLAGS.

Robert Walker reported a segmentation fault is observed when process
CoreSight trace data; this issue can be easily reproduced by the command
'perf report --itrace=i1000i' for decoding tracing data.
If neither the 'b' flag (synthesize branches events) nor 'l' flag
(synthesize last branch entries) are specified to option '--itrace',
cs_etm_queue::prev_packet will not been initialised. After merging the
code to support exception packets and sample flags, there introduced a
number of uses of cs_etm_queue::prev_packet without checking whether it
is valid, for these cases any accessing to uninitialised prev_packet
will cause crash.
As cs_etm_queue::prev_packet is used more widely now and it's already
hard to follow which functions have been called in a context where the
validity of cs_etm_queue::prev_packet has been checked, this patch
always allocates memory for cs_etm_queue::prev_packet.
