From: Christoph Hellwig <hch@lst.de>
Date: 2020-05-10 07:57:42
Also in:
linux-alpha, linux-arch, linux-arm-kernel, linux-fsdevel, linux-m68k, linux-mips, linux-mm, linux-riscv, linux-sh, linux-um, lkml, sparclinux
Subsystem:
arm port, sparc + ultrasparc (sparc/sparc64), the rest · Maintainers:
Russell King, "David S. Miller", Andreas Larsson, Linus Torvalds
flush_icache_user_range is only used by <asm-generic/cacheflush.h>, so remove it from the architectures that implement it, but don't use <asm-generic/cacheflush.h>.
