Merge tag 'acpica-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPICA updates from Rafael Wysocki: "Additional ACPICA material for v4.2-rc1 This will update the ACPICA code in the kernel to upstream revision 20150619 (a bug-fix release mostly including stable-candidate fixes) and restore an earlier ACPICA commit that had to be reverted due to a regression introduced by it (the regression is addressed by blacklisting the only known system affected by it to date). The only new feature added by this update is the support for overriding objects in the ACPI namespace and a new ACPI table that can be used for that called the Override System Definition Table (OSDT). That should allow us to "patch" the ACPI namespace built from incomplete or incorrect ACPI System Definition tables (DSDT, SSDT) during system startup without the need to provide replacements for all of those tables in the future. Specifics: - Fix system resume problems related to 32-bit and 64-bit versions of the Firmware ACPI Control Structure (FACS) in the firmare (Lv Zheng) - Fix double initialization of the FACS (Lv Zheng) - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit) - Add support for the (currently missing) new GIC version field in the Multiple APIC Description Table (MADT) (Hanjun Guo) - Add support for overriding objects in the ACPI namespace to ACPICA and OSDT support (Lv Zheng, Bob Moore, Zhang Rui) - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore) - Restore the commit modifying _REV to always return "2" (as required by ACPI 6) and add a blacklisting mechanism for systems that may be affected by that change (Rafael J Wysocki) - Assorted fixes and cleanups (Bob Moore, Lv Zheng, Sascha Wildner)" * tag 'acpica-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (28 commits) Revert 'Revert "ACPICA: Permanently set _REV to the value '2'."' ACPI / init: Make it possible to override _REV ACPICA: Update version to 20150619 ACPICA: Comment update, no functional change ACPICA: Update TPM2 ACPI table ACPICA: Update definitions for the TCPA and TPM2 ACPI tables ACPICA: Split C library prototypes to new header ACPICA: De-macroize calls to standard C library functions ACPI / acpidump: Update acpidump manual ACPICA: acpidump: Convert the default behavior to dump from /sys/firmware/acpi/tables ACPICA: acpidump: Allow customized tables to be dumped without accessing /dev/mem ACPICA: Cleanup output for the ASL Debug object ACPICA: Update for acpi_install_table memory types ACPICA: Namespace: Change namespace override to avoid node deletion ACPICA: Namespace: Add support of OSDT table ACPICA: Namespace: Add support to allow overriding objects ACPICA: ACPI 6.0: Add values for MADT GIC version field ACPICA: Utilities: Add _CLS processing ACPICA: Add dragon_fly support to unix file mapping file ACPICA: EFI: Add EFI interface definitions to eliminate dependency of GNU EFI ...
