  x86/fpu: Restore the masking out of reserved MXCSR bits (2021-10-08 11:12:17 +0200)

----------------------------------------------------------------
- A FPU fix to properly handle invalid MXCSR values: 32-bit masks them
out due to histerical reasons and 64-bit kernels reject them

- A fix to clear X86_FEATURE_SMAP when support for is not config-enabled

- Three fixes correcting misspelled Kconfig symbols used in code

- Two resctrl object cleanup fixes

- Yet another attempt at fixing the neverending saga of botched x86
timers, this time because some incredibly smart hardware decides to turn
off the HPET timer in a low power state - who cares if the OS is relying
on it...

- Check the full return value range of an SEV VMGEXIT call to determine
whether it returned an error
