[PATCH v1 03/13] arm64: Downgrade flush_icache_range to invalidate
From: Fuad Tabba <hidden>
Date: 2021-05-11 14:45:02
Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
Since __flush_dcache_area is called right before, invalidate_icache_range is sufficient in this case. No functional change intended.
