Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
"Nothing major, some left-overs from the recent merging window (MTE,
coco) and some newly found issues like the ptrace() ones.
- MTE/hugetlbfs:
- Set VM_MTE_ALLOWED in the arch code and remove it from the core
code for hugetlbfs mappings
- Fix copy_highpage() warning when the source is a huge page but
not MTE tagged, taking the wrong small page path
- drivers/virt/coco:
- Add the pKVM and Arm CCA drivers under the arm64 maintainership
- Fix the pkvm driver to fall back to ioremap() (and warn) if the
MMIO_GUARD hypercall fails
- Keep the Arm CCA driver default 'n' rather than 'm'
- A series of fixes for the arm64 ptrace() implementation,
potentially leading to the kernel consuming uninitialised stack
variables when PTRACE_SETREGSET is invoked with a length of 0
- Fix zone_dma_limit calculation when RAM starts below 4GB and
ZONE_DMA is capped to this limit
- Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a
call to page_to_phys() (from patch_map()) which checks pfn_valid()
before vmemmap has been set up
- Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI
ops when the kernel assumes 8-bit ASIDs but running under a
hypervisor on a system that implements 16-bit ASIDs (found running
Linux under Parallels on Apple M4)
- ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it
is using the same SMMU PMCG as HIP09 and suffers from the same
errata
- Add GCS to cpucap_is_possible(), missed in the recent merge"
