Guo Ren b6a41435c8 csky: syscache: Fixup duplicate cache flush ... [ Upstream commit 6ea42c84f33368eb3fe1ec1bff8d7cb1a5c7b07a ] The current csky logic of sys_cacheflush is wrong, it'll cause icache flush call dcache flush again. Now fixup it with a conditional "break & fallthrough". Fixes: 997153b9a7 ("csky: Add flush_icache_mm to defer flush icache all") Fixes: 0679d29d3e23 ("csky: fix syscache.c fallthrough warning") Acked-by: Randy Dunlap <rdunlap@infradead.org> Co-Developed-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Guo Ren <guoren@linux.alibaba.com> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-07-14 16:56:52 +02:00
