Subject: [PATCH v3 0/3] arm64: tlb: add support for TLBI RANGE instructions
Date: Wed, 15 Jul 2020 15:19:42 +0800 [thread overview]
Message-ID: <20200715071945.897-1-yezhenyu2@huawei.com> (raw)
NOTICE: this series are based on the arm64 for-next/tlbi branch:
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/tlbi
ARMv8.4-TLBI provides TLBI invalidation instruction that apply to a
range of input addresses. This series add support for this feature.

ChangeList:
v3:
- add check on whether binutils supports ARMv8.4-a instructions.
- pass -march=armv8.4-a to KBUILD_CFLAGS.
- make __TLBI_RANGE_PAGES to be 'unsigned long' explicitly.
v2:
- remove the __tlbi_last_level() macro.
- add check for parameters in __TLBI_VADDR_RANGE macro.
