Hello Linus,
Please pull the following arm64 updates for 4.11. The summary is in the
tag below.
The diffstat strays outside of arch/arm64 in a few places:
- The core changes required for DEBUG_VIRTUAL (Acked, also merged by rmk)
- Qualcomm SMCCC quirk (Olof suggested I take this)
- ACPI/IORT changes (Rafael has asked for arm64 ACPI stuff to go via arm64)
- Perf/PMU drivers (arm64-specific and maintained by me)
There were a few features that didn't make the pull (kdump, ACPI PMU,
RAS/APEI) but hopefully they'll be ready for 4.12.
Cheers,
Will
