Linus Torvalds 4cbdd58dfa Perf events updates:
- Support SIMD/eGPRs/SSP register sampling in perf
    (Dapeng Mi, Kan Liang)
 
  - Turn amd_uncore_ctx events into a flexible array (Rosen Penev)
 
  - Finish the work related to fixing the guest PEBS path to not
    set unwanted PERF_GLOBAL_CTRL bits, for which urgent fixes
    are upstream already (Sean Christopherson)
 
  - Drop redundant counter slot searches in the AMD uncore
    driver (Usama Arif)
 
  - Don't WARN when the ext_regs_buf allocation fails (vineash)
