This patch set have no function change for x86 and ia64 and
just do some clean up to prepare for running ACPI on ARM64.
This patch set is splited out from the patch set [1]
"[PATCH v4 00/13] Enable ACPI on ARM64 in Kconfig" and hope it
can be merged first before ARM64 ACPI core patches.

Graeme Gregory (2):
ACPI: ARM64 does not have a BIOS add config for BIOS table scan.
ACPI: Don't use acpi_lapic in ACPI core code

ACPI / processor: Introduce ARCH_HAS_ACPI_PDC
ACPI: Make EC debugfs depend on X86 || IA64 in Kconfig

1.7.9.5
APEI is currently implemented so that it depends on x86 hardware.
The primary dependency is that GHES uses the x86 NMI for hardware
error notification and MCE for memory error handling. These patches
remove that dependency.
Other APEI features such as error reporting via external IRQ, error
serialization, or error injection, do not require changes to use them
on non-x86 architectures.
The following patch set eliminates the APEI Kconfig x86 dependency
by making these changes:
- treat NMI notification as GHES architecture - HAVE_ACPI_APEI_NMI
- group and wrap around #ifdef CONFIG_HAVE_ACPI_APEI_NMI code which
is used only for NMI path
- identify architectural boxes and abstract it accordingly (tlb flush and MCE)
- rework ioremap for both IRQ and NMI context
NMI code is kept in ghes.c file since NMI and IRQ context are tightly coupled.
Note, these patches introduce no functional changes for x86. The NMI notification
feature is hard selected for x86. Architectures that want to use this
feature should also provide NMI code infrastructure.
V1->V2
- address Borislav's comment
- abstract arch-specific calls instead of wrapping into the #ifdef
V2->V3
- address Robert's comment
- disable ACPI_APEI_NMI selection so that it is hard selected by arch Kconfig
- rename ACPI_APEI_NMI to ARCH_HAS_ACPI_APEI_NMI
V3->V4
- do not abstract NMI calls for archs which do not support it
- merge some of patches to make review process easier
Tomasz Nowicki (3):
apei, mce: Factor out APEI architecture specific MCE calls.
acpi, apei, ghes: Make NMI error notification to be GHES architecture
extension.
acpi, apei, ghes: Factor out ioremap virtual memory for IRQ and NMI
context.

1.7.9.5
This patch set is the first part of ARM64 ACPI core patches to
running ACPI on ARM64, it just handle some compile errors when
ACPI is introduced to ARM64 platform and enable ACPI on ARM64
in Kconfig.
Following core patch sets for ACPI based SMP/GIC/Arch Timer
initialization to enable ACPI on ARM64 are under interally
review and will send out when ACPI 5.1 is released.
patch 1~3 are cleanups for ACPI core;
patch 4~13 are arch dependent code for ARM64 ACPI;
This patch set is based on linux-next branch of Rafael's linux-pm
tree, and PCI patches for ARM64 from Liviu:
Support for creating generic host_bridge from device tree
https://lkml.org/lkml/2014/3/14/279
Add support for PCI in AArch64
http://comments.gmane.org/gmane.linux.ports.arm.kernel/309392
Changes since v3:
- Introduce three new patches
- acpi: arm64 does not have a BIOS add config for BIOS table scan
- ACPI: Don't use acpi_lapic in ACPI core code
- ARM64 / ACPI: if we chose to boot from acpi then disable FDT
- Rebase on the latest linux-next branch of Rafael's tree, and
introduce asm/acenv.h for ARM64;
- Introduce ARCH_HAS_ACPI_PDC to move all the _PDC related code
to a single place and make x86 and ia64 select ARCH_HAS_ACPI_PDC;
- Fix some checpatch warning;
- Fix broken Signed-off-by chain;
- Remove duplicate interface macros for ACPICA pointed out by Mark
Rutland and Zheng Lv;
- Redefine ACPI_FLUSH_CPU_CACHE();
- Stub out some PCI functions suggested by Arnd and already merged into 3.16
Comments still need to be addressed:
- Empty PCI implementation in arch/arm64 which suggested by Arnd;
- suspend and sleep on ARM64 platform pointed out by Lorenzo;
Changes since v2:
- Make ACPI depend on PCI on ARM64
- rework all the patches and seperate some of the patches
into fine-grained, and add some comments and changelog to
make it easier for review.

ARM64 / ACPI: Introduce arm-core.c and its related head file
