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'."'

ACPICA: Update definitions for the TCPA and TPM2 ACPI tables

2015-07-01T21:17:56Z

ACPICA commit 33140b4498666337dd33a00cf3c4797a53981a7b Changes for a new version of the 3rd party spec for these tables, the "TCG ACPI Specification", December 14, 2014. Also, moved the definition of TPM2 to actbl2.h, next to TCPA, since both should be together. Update the table compiler/disassembler code for the tables. However, the "Server" TCPA table is not supported at this time.

ACPICA: De-macroize calls to standard C library functions

ACPICA commit 3b1026e0bdd3c32eb6d5d313f3ba0b1fee7597b4 ACPICA commit 00f0dc83f5cfca53b27a3213ae0d7719b88c2d6b ACPICA commit 47d22a738d0e19fd241ffe4e3e9d4e198e4afc69 Across all of ACPICA. Replace C library macros such as ACPI_STRLEN with the standard names such as strlen. The original purpose for these macros is long since obsolete. Also cast various invocations as necessary.

ACPICA: Namespace: Change namespace override to avoid node deletion

2015-07-01T21:17:54Z

ACPICA commit c0ce529e1fbb8ec47d2522a3aa10f3ab77e16e41 There is no reference counting implemented for struct acpi_namespace_node, so it is currently not removable during runtime. This patch changes the namespace override code to keep the old struct acpi_namespace_node undeleted so that the override mechanism can happen during runtime. Bob Moore.

ACPICA: EFI: Add EFI interface definitions to eliminate dependency of GNU EFI

2015-07-01T21:17:53Z

ACPICA commit 5d00e67a74542d030f0a55e7a947a020ef0d9693 This patch copies EFI interface definitions to the ACPICA code base so that the EFI utility support can be ported to other EFI implementation. Known issues: 1. MS Builds of uefi_call_wrapper() The uefi_call_wrapper() in GNU EFI is implemented in a the way to work around the ABI difference between Unix and MS. While I don't have environment to test the MS builds. In order to port the ACPICA utilities to other EFI implementation, all that need to be done is to impelement the 64-bit division support and the program entry point where the efi_main() is invoked. Code to impelement these is platform specific, and ACPICA currently choose to hide such platform specific code within the specific EFI impelementation. Lv Zheng.
