  x86/asm: Add an enqcmds() wrapper for the ENQCMDS instruction (2020-10-07 17:53:08 +0200)

----------------------------------------------------------------
Initial support for sharing virtual addresses between the CPU and
devices which doesn't need pinning of pages for DMA anymore. Add support
for the command submission to devices using new x86 instructions like
ENQCMD{,S} and MOVDIR64B. In addition, add support for process address
space identifiers (PASIDs) which are referenced by those command
submission instructions along with the handling of the PASID state on
context switch as another extended state. Work by Fenghua Yu, Ashok Raj,
Yu-cheng Yu and Dave Jiang.

----------------------------------------------------------------
Ashok Raj (1):
      Documentation/x86: Add documentation for SVA (Shared Virtual Addressing)

Dave Jiang (2):
      x86/asm: Carve out a generic movdir64b() helper for general usage
      x86/asm: Add an enqcmds() wrapper for the ENQCMDS instruction

Fenghua Yu (7):
      drm, iommu: Change type of pasid to u32
      iommu/vt-d: Change flags type to unsigned int in binding mm
      x86/cpufeatures: Enumerate ENQCMD and ENQCMDS instructions
      x86/msr-index: Define an IA32_PASID MSR
      mm: Add a pasid member to struct mm_struct
      x86/cpufeatures: Mark ENQCMD as disabled when configured out
      x86/mmu: Allocate/free a PASID

Yu-cheng Yu (1):
      x86/fpu/xstate: Add supervisor PASID state for ENQCMD
