The patch titled
Subject: asm-generic: fix a compilation warning
has been removed from the -mm tree. Its filename was
asm-generic-fix-a-compilation-warning.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Qian Cai <cai@xxxxxx>
Subject: asm-generic: fix a compilation warning
Fix this compilation warning on x86 by making flush_cache_vmap() inline.
lib/ioremap.c: In function 'ioremap_page_range':
lib/ioremap.c:214:16: warning: variable 'start' set but not used
[-Wunused-but-set-variable]
unsigned long start;
^~~~~
While at it, convert all other similar functions to inline for
consistency.
