Changelog: v4: Rebase to latest kernel version(4.4-rc4). Move arch_apei_flush_tlb_one into header file as a inline function Add a new subfunction "hest_ia_init" for "acpi_disable_cmcff".
v3: https://lkml.org/lkml/2015/12/3/521 Remove "acpi_disable_cmcff" from arm64 code, and wrap it in hest.c by "#if defined(__i386__) || defined(__x86_64__)"
v2: https://lkml.org/lkml/2015/12/2/432 Rebase to latest kernel version(4.4-rc3). Move arch_apei_flush_tlb_one() to arch/arm64/kernel/acpi.c
v1: https://lkml.org/lkml/2015/8/14/199 Move arch_apei_flush_tlb_one() to arch/arm64/include/asm/apci.h. Delete arch/arm64/kernel/apei.c. Add "#ifdef CONFIG_ACPI_APEI" for "acpi_disable_cmcff".
