# Merge: 7b664cc38ea7 97740266de26
# Author: Linus Torvalds <torvalds@linux-foundation.org>

#     Merge tag 'x86_mm_for_6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull x86 LAM (Linear Address Masking) support from Dave Hansen:
#      "Add support for the new Linear Address Masking CPU feature.
#     
#       This is similar to ARM's Top Byte Ignore and allows userspace to store
#       metadata in some bits of pointers without masking it out before use"
#     
#     * tag 'x86_mm_for_6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
#       x86/mm/iommu/sva: Do not allow to set FORCE_TAGGED_SVA bit from outside
#       x86/mm/iommu/sva: Fix error code for LAM enabling failure due to SVA
#       selftests/x86/lam: Add test cases for LAM vs thread creation
#       selftests/x86/lam: Add ARCH_FORCE_TAGGED_SVA test cases for linear-address masking

#       mm: Expose untagging mask in /proc/$PID/status
#       x86/mm: Provide arch_prctl() interface for LAM
#       x86/mm: Reduce untagged_addr() overhead for systems without LAM
#       x86/uaccess: Provide untagged_addr() and remove tags before address check
#       mm: Introduce untagged_addr_remote()
#       x86/mm: Handle LAM on context switch
#       x86: CPUID and CR3/CR4 flags for Linear Address Masking
#       x86: Allow atomic MM_CONTEXT flags setting
#       x86/mm: Rework address range check in get_user() and put_user()
