Pull ACPI fixes from Rafael Wysocki:
 "These fix two recent issues in the ACPI memory mappings management
  code and tighten up error handling in the ACPI driver for AMD SoCs
  (APD).

  Specifics:

   - Avoid redundant rounding to the page size in acpi_os_map_iomem() to
     address a recently introduced issue with the EFI memory map
     permission check on ARM64 (Ard Biesheuvel).

   - Fix acpi_release_memory() to wait until the memory mappings
     released by it have been really unmapped (Rafael Wysocki).

   - Make the ACPI driver for AMD SoCs (APD) check the return value of
     acpi_dev_get_property() to avoid failures in the cases when the
     device property under inspection is missing (Furquan Shaikh)"

# Based on the vmlinux file create the System.map file
# System.map is used by module-init tools and some debugging
# tools to retrieve the actual addresses of symbols in the kernel.
#
# Usage
# mksysmap vmlinux System.map


#####
# Generate System.map (actual filename passed as second argument)

# $NM produces the following output:
# f0081e80 T alloc_vfsmnt

#   The second row specify the type of the symbol:
#   A = Absolute
#   B = Uninitialised data (.bss)
#   C = Common symbol
#   D = Initialised data
#   G = Initialised data for small objects
#   I = Indirect reference to another symbol
#   N = Debugging symbol
#   R = Read only
#   S = Uninitialised data for small objects
#   T = Text code symbol
#   U = Undefined symbol
#   V = Weak symbol
#   W = Weak symbol
#   Corresponding small letters are local symbols

# For System.map filter away:
#   a - local absolute symbols
#   U - undefined global symbols
#   N - debugging symbols
#   w - local weak symbols

# readprofile starts reading symbols when _stext is found, and
# continue until it finds a symbol which is not either of 'T', 't',
# 'W' or 'w'. __crc_ are 'A' and placed in the middle
# so we just ignore them to let readprofile continue to work.
# (At least sparc64 has __crc_ in the middle).
