Hi all,
After merging the percpu tree, today's linux-next build (sparc64
defconfig) failed like this:
mm/percpu.c: In function 'pcpu_page_first_chunk':
mm/percpu.c:3336:17: error: implicit declaration of function 'flush_cache_vmap_early'; did you mean 'flush_cache_vmap'? [-Werror=implicit-function-declaration]
3336 | flush_cache_vmap_early(unit_addr, unit_addr + ai->unit_size);
| ^~~~~~~~~~~~~~~~~~~~~~
| flush_cache_vmap
cc1: some warnings being treated as errors
Caused by commit
a95c15a43f4a ("mm: Introduce flush_cache_vmap_early() and its riscv implementation")
I have applied the following fix patch for today. Are there other
archs that don't use asm-generic/cacheflush.h?
