  perf/core: Avoid put_page() when GUP fails (2021-11-11 13:09:34 +0100)

----------------------------------------------------------------
- Prevent unintentional page sharing by checking whether a page
reference to a PMU samples page has been acquired properly before that

- Make sure the LBR_SELECT MSR is saved/restored too

- Reset the LBR_SELECT MSR when resetting the LBR PMU to clear any
residual data left
