The CMD13 polling is needed for commands with R1B responses. In commit
a0d4c7eb71 ("mmc: block: Add CMD13 polling for MMC IOCTLS with R1B
response"), the intent was to introduce this for requests targeted to the
RPMB partition. However, the condition to trigger the polling loop became
wrong, leading to unnecessary polling. Let's fix the condition to avoid
this.

In the TDP MMU, use shadow_phys_bits to dermine the maximum possible GFN
mapped in the guest for zapping operations. boot_cpu_data.x86_phys_bits
may be reduced in the case of HW features that steal HPA bits for other
purposes. However, this doesn't necessarily reduce GPA space that can be
accessed via TDP. So zap based on a maximum gfn calculated with MAXPHYADDR
retrieved from CPUID. This is already stored in shadow_phys_bits, so use
it instead of x86_phys_bits.

My patch caused kernel Oopses and delays in boot. Revert it.
The problem was that I moved the "mem->dma = paddr;" before the call to
be_fill_queue(). But the first thing that the be_fill_queue() function
does is memset the whole struct to zero which overwrites the assignment.

The "skb" is freed by the transmit code in cxgb4_ofld_send() and we
shouldn't use it again. But in the current code, if we hit an error
later on in the function then the clean up code will call kfree_skb(skb)
and so it causes a double free.
Set the "skb" to NULL and that makes the kfree_skb() a no-op.

Currently .get_state() and .apply() use dev_get_drvdata() on the struct
device related to the pwm chip. This only works after .probe() called
platform_set_drvdata() which in this driver happens only after
pwmchip_add() and so comes possibly too late.
Instead of setting the driver data earlier use the traditional
container_of approach as this way the driver data is conceptually and
computational nearer.

Lilith >_> and Claudio Bozzato of Cisco Talos security team reported
that collect_syscall() improperly casts the syscall registers to 64-bit
values leaking the uninitialized last 24 bytes on 32-bit platforms, that
are visible in /proc/self/syscall.
The cause is that info->data.args are u64 while syscall_get_arguments()
uses longs, as hinted by the bogus pointer cast in the function.
Let's just proceed like the other call places, by retrieving the
registers into an array of longs before assigning them to the caller's
array. This was successfully tested on x86_64, i386 and ppc32.

The current memory region move test correctly handles the situation that
the second (realigning) memslot move operation would temporarily trigger
MMIO until it completes, however it does not handle the case in which the
first (misaligning) move operation does this, too.
This results in false test assertions in case it does so.
Fix this by handling temporary MMIO from the first memslot move operation
in the test guest code, too.

The kernel cannot disambiguate when 2+ PEBS counters overflow at the
same time. This is what the comment for this code suggests. However,
I see the comparison is done with the unfiltered p->status which is a
copy of IA32_PERF_GLOBAL_STATUS at the time of the sample. This
register contains more than the PEBS counter overflow bits. It also
includes many other bits which could also be set.

The commit 3966c3feca ("x86/perf/amd: Remove need to check "running"
bit in NMI handler") introduced this. It seems x86_pmu_stop can be
called recursively (like when it losts some samples) like below:
x86_pmu_stop
intel_pmu_disable_event (x86_pmu_disable)
intel_pmu_pebs_disable
intel_pmu_drain_pebs_nhm (x86_pmu_drain_pebs_buffer)
x86_pmu_stop
While commit 35d1ce6bec ("perf/x86/intel/ds: Fix x86_pmu_stop
warning for large PEBS") fixed it for the normal cases, there's
another path to call x86_pmu_stop() recursively when a PEBS error was
detected (like two or more counters overflowed at the same time).
Like in the Kan's previous fix, we can skip the interrupt accounting
for large PEBS, so check the iregs which is set for PMI only.
