Adding perf_msr_probe function to provide interface for
checking up on MSR register and set the related attribute
group visibility.
User defines following struct for each MSR register:
struct perf_msr {

There's no need to have special code for getting
the bit and msr value for given event. We can

hi,
following up on [1], [2] and [3], this patchset adds update
attribute groups to pmu, factors out the MSR probe code and
use it in msr,cstate* and rapl PMUs.
The functionality stays the same with one exception:
for msr PMU: the event is not exported if the rdmsr return zero
on event's msr,
We get rapl_cntr_mask from perf_msr_probe call, as a replacement
for current intel_rapl_init_fun::cntr_mask value for each model.

All callers of lockdep_assert_held_exclusive use it to verify the
correct locking state of either a semaphore (ldisc_sem in tty,
mmap_sem for perf events, i_rwsem of inode for dax) or rwlock by
apparmor. Thus it makes sense to rename _exclusive to _write since
that's the semantics callers care.

If CRYPTO_DEV_ATMEL_ECC is set m, which select CRC16 to m,
while CRYPTO_DEV_ATMEL_SHA204A is set to y, building fails.

This patch implements an extension of eventfd (EFD_VPOLL) to define file
descriptors
whose I/O events can be generated at user level. These file descriptors
trigger notifications for [p]select/[p]poll/epoll.
This feature is useful for user-level implementations of network stacks

systemd-modules-load.service automatically tries to load the pkey module
on systems that have MSA.
Pkey also requires the MSA3 facility and a bunch of subfunctions.
Failing with -EOPNOTSUPP makes "systemd-modules-load.service" fail on
any system that does not have all needed subfunctions. For
