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
---------------------------------------------------------------- Borislav Petkov (1): x86/fpu: Restore the masking out of reserved MXCSR bits
James Morse (2): x86/resctrl: Free the ctrlval arrays when domain_setup_mon_state() fails x86/resctrl: Fix kfree() of the wrong type in domain_add_cpu()
Lukas Bulwahn (3): x86/entry: Correct reference to intended CONFIG_64_BIT x86/platform/olpc: Correct ifdef symbol to intended CONFIG_OLPC_XO15_SCI x86/Kconfig: Correct reference to MWINCHIP3D
Thomas Gleixner (1): x86/hpet: Use another crystalball to evaluate HPET usability
Tom Lendacky (1): x86/sev: Return an error on a returned non-zero SW_EXITINFO1[31:0]
Vegard Nossum (1): x86/entry: Clear X86_FEATURE_SMAP when CONFIG_X86_SMAP=n
