Subject: [GIT PULL] perf events updates for v5.14

Linus,

Please pull the latest perf/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2021-06-28

   # HEAD: 012669c740e6e2afa8bdb95394d06676f933dd2d perf: Fix task context PMU for Hetero

Perf events updates for this cycle:

 - Platform PMU driver updates:

     - x86 Intel uncore driver updates for Skylake (SNR) and Icelake (ICX) servers
     - Fix RDPMC support
     - Fix [extended-]PEBS-via-PT support
     - Fix Sapphire Rapids event constraints
     - Fix :ppp support on Sapphire Rapids
     - Fix fixed counter sanity check on Alder Lake & X86_FEATURE_HYBRID_CPU
     - Other heterogenous-PMU fixes

 - Kprobes:

     - Remove the unused and misguided kprobe::fault_handler callbacks.
     - Warn about kprobes taking a page fault.
     - Fix the 'nmissed' stat counter.

 - Misc cleanups and fixes.

 Thanks,
