Fix a double free and an uninitialized pointer read error. Both tmp and
new are pointing at same address and both are freed which leads to
double free. Adding a check to verify if new and tmp are free in the
error_free label fixes the double free issue. new is not initialized to
null which also leads to a free on an uninitialized pointer.

When kfd_ioctl_wait_events needs to restart due to a signal, we need to
update the timeout to account for the time already elapsed. We also need
to undo auto_reset of events that have signaled already, so that the
restarted ioctl will be able to count those signals again.
This fixes infinite hangs when kfd_ioctl_wait_events is interrupted by a
signal.

[Why]
After TDR recovery, eDP and USB4 display does not light up. Because
dmub outbox notifications are not enabled after dmub reload and link
encoder assignments for the streams are not cleared before dc state
reset.
[How]
- Dmub outbox notification is enabled after tdr recovery by issuing
inbox command to dmub.
- Link encoders for the streams are unassigned before dc state reset.

[Why & How]
When multiple displays are used, the underlying framebuffers could be
two separate framebuffers, or a single large framebuffer. Fix the
calculation logic for CAB to account for large framebuffer. Current
logic assumes that any FB that the plane points to are independent. When
a single FB is used on the system, this does 2 times allocation.
Add a check to prevent duplicate allocation by checking if the base
addresses are the same, and then ensuring that the if we allocate using
the pitch, whole of the other fbs will be accounted for in the first
allocation.

Now that the PMU is refreshed when MSR_IA32_PERF_CAPABILITIES is written
by host userspace, zero out the number of LBR records for a vCPU during
PMU refresh if PMU_CAP_LBR_FMT is not set in PERF_CAPABILITIES instead of
handling the check at run-time.
guest_cpuid_has() is expensive due to the linear search of guest CPUID
entries, intel_pmu_lbr_is_enabled() is checked on every VM-Enter, _and_
simply enumerating the same "Model" as the host causes KVM to set the
number of LBR records to a non-zero value.

Refresh the PMU if userspace modifies MSR_IA32_PERF_CAPABILITIES. KVM
consumes the vCPU's PERF_CAPABILITIES when enumerating PEBS support, but
relies on CPUID updates to refresh the PMU. I.e. KVM will do the wrong
thing if userspace stuffs PERF_CAPABILITIES _after_ setting guest CPUID.
Opportunistically fix a curly-brace indentation.

Test all possible input values to verify that KVM rejects all values
except the exact host value. Due to the LBR format affecting the core
functionality of LBRs, KVM can't emulate "other" formats, so even though
there are a variety of legal values, KVM should reject anything but an
exact host match.

sched_getcpu() is glibc dependent and it can simply return the CPU
ID from the registered rseq information, as Florian Weimer pointed.
In this case, it's pointless to compare the return value from
sched_getcpu() and that fetched from the registered rseq information.
Fix the issue by replacing sched_getcpu() with getcpu(), as Florian
suggested. The comments are modified accordingly by replacing
"sched_getcpu()" with "getcpu()".

The rseq information is registered by TLS, starting from glibc-2.35.
In this case, the test always fails due to syscall(__NR_rseq). For
example, on RHEL9.1 where upstream glibc-2.35 features are enabled
on downstream glibc-2.34, the test fails like below.
# ./rseq_test
==== Test Assertion Failure ====
rseq_test.c:60: !r
pid=112043 tid=112043 errno=22 - Invalid argument
1 0x0000000000401973: main at rseq_test.c:226

4 0x0000000000401b6f: _start at ??:?
rseq failed, errno = 22 (Invalid argument)
# rpm -aq | grep glibc-2
glibc-2.34-39.el9.aarch64
Fix the issue by using "../rseq/rseq.c" to fetch the rseq information,
registred by TLS if it exists. Otherwise, we're going to register our
own rseq information as before.
