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)" * tag 'acpi-5.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: OSL: Prevent acpi_release_memory() from returning too early ACPI: ioremap: avoid redundant rounding to OS page size ACPI: SoC: APD: Check return value of acpi_dev_get_property()
