Revision 0b2f18e7aeef86f966bbfccec8d698e05ccc4631 authored by Linus Torvalds on 28 August 2020, 20:17:14 UTC, committed by Linus Torvalds on 28 August 2020, 20:17:14 UTC
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)"
