linux-toradex.git/arch/mn10300/mm/cache-disabled.c, branch v4.2.4 Linux kernel for Apalis and Colibri modules MN10300: Handle missing sys_cacheflush() when caching disabled 2010-09-29T01:01:14+00:00 David Howells dhowells@redhat.com 2010-09-29T00:57:02+00:00 62bdb288bf464862a2801b2e53aadc6c4d100fab When caching is disabled on the MN10300 arch, the sys_cacheflush() function is removed by conditional stuff in the makefiles, but is still referred to by the syscall table. Provide a null version that just returns 0 when caching is disabled (or -EINVAL if the arguments are silly).

When caching is disabled on the MN10300 arch, the sys_cacheflush()
function is removed by conditional stuff in the makefiles, but is still
referred to by the syscall table.

Provide a null version that just returns 0 when caching is disabled (or
-EINVAL if the arguments are silly).
