  arm64: hibernate: Fix level3 translation fault in swsusp_save() (2024-04-19 16:33:00 +0100)

----------------------------------------------------------------
arm64 fixes:

- Fix a kernel fault during page table walking in huge_pte_alloc() with
  PTABLE_LEVELS=5 due to using p4d_offset() instead of p4d_alloc()

- head.S fix and cleanup to disable the MMU before toggling the
  HCR_EL2.E2H bit when entering the kernel with the MMU on from the EFI
  stub. Changing this bit (currently from VHE to nVHE) causes some
  system registers as well as page table descriptors to be interpreted
  differently, potentially resulting in spurious MMU faults

- Fix translation fault in swsusp_save() accessing MEMBLOCK_NOMAP memory
  ranges due to kernel_page_present() returning true in most
  configurations other than rodata_full == true,
  CONFIG_DEBUG_PAGEALLOC=y or CONFIG_KFENCE=y
