Merge branch 'for-next/mm' into for-next/core

* for-next/mm:
  arm64: mm: Test for pmd_sect() in vmemmap_check_pmd()
  arm64/mm: Replace open encodings with PXD_TABLE_BIT
  arm64/mm: Rename pte_mkpresent() as pte_mkvalid()
  arm64: Kconfig: force ARM64_PAN=y when enabling TTBR0 sw PAN
  arm64/kvm: Avoid invalid physical addresses to signal owner updates
  arm64/kvm: Configure HYP TCR.PS/DS based on host stage1
  arm64/mm: Override PARange for !LPA2 and use it consistently
  arm64/mm: Reduce PA space to 48 bits when LPA2 is not enabled
