#     Pull perf fixes from Thomas Gleixner:
#      "Two perf fixes:
#     
#        - Do not check the LBR_TOS MSR when setting up unrelated LBR MSRs as
#          this can cause malfunction when TOS is not supported
#     
#        - Allocate the LBR XSAVE buffers along with the DS buffers upfront
#          because allocating them when adding an event can deadlock"
