Subject: [PATCH] block: blk-iocost: fix build for ARCH with missing local64.h files
Date: Wed, 9 Dec 2020 12:46:57 -0800 [thread overview]
Message-ID: <20201209204657.6676-1-rdunlap@infradead.org> (raw)
When building block/blk-iocost.c on arch/x6x/ or arch/nios2/, the
build fails due to missing the <asm/local64.h> file.
Fix this by adding local64.h as a "generic-y" file in their respective
Kbuild files, so that they will use a copy of <asm-generic/local64.h>
instead (copied to arch/*/include/generated/local64.h by the
build system).
c6x or nios2 build error:
../block/blk-iocost.c:183:10: fatal error: asm/local64.h: No such file or directory
183 | #include <asm/local64.h>
Fixes: 5e124f74325d ("blk-iocost: use local[64]_t for percpu stat")
