x86/resctrl: Don't move a task to the same resource group (2021-01-08
09:08:03 +0100)
----------------------------------------------------------------
- A fix for fanotify_mark() missing the conversion of x86_32 native
syscalls which take 64-bit arguments to the compat handlers due to
former having a general compat handler. (Brian Gerst)
- Add a forgotten pmd page destructor call to pud_free_pmd_page() where
a pmd page is freed. (Dan Williams)
- Make IN/OUT insns with an u8 immediate port operand handling for
SEV-ES guests more precise by using only the single port byte and not
the whole s32 value of the insn decoder. (Peter Gonda)
- Correct a straddling end range check before returning the proper MTRR
type, when the end address is the same as top of memory. (Ying-Tsun
Huang)
- Change PQR_ASSOC MSR update scheme when moving a task to a resctrl
resource group to avoid significant performance overhead with some
resctrl workloads. (Fenghua Yu)
- Avoid the actual task move overhead when the task is already in the
resource group. (Fenghua Yu)
