Subject: [GIT PULL] ACPI fixes for v5.9-rc3

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-5.9-rc3

with top-most commit 4f31d53c21ec98a2c8973cff759804bd1c217c93

 Merge branch 'acpi-mm'

on top of commit 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5

 Linux 5.9-rc1

to receive ACPI fixes for 5.9-rc3.

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).

Thanks!
