Linus Torvalds 6ebb6814a1 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.
