Merge tag 'perf-urgent-2021-05-23' of git://
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" * tag 'perf-urgent-2021-05-23' of git:// perf/x86/lbr: Remove cpuc->lbr_xsave allocation from atomic context perf/x86: Avoid touching LBR_TOS MSR for Arch LBR
