Merge branch 'apei' into release
Conflicts:
drivers/acpi/apei/apei-base.c
This was a conflict between
15afae604651d4e17652d2ffb56f5e36f991cfef
(CPI, APEI: Fix incorrect APEI register bit width check and usage)
and
653f4b538f66d37db560e0f56af08117136d29b7
(ACPICA: Expand OSL memory read/write interfaces to 64 bits)
The former changed a parameter in the call to acpi_os_read_memory64()
and the later replaced all calls to acpi_os_read_memory64()
with calls to acpi_os_read_memory().
