Subject: [PATCH 08/17] microblaze: mark flush_dcache_folio() inline

From: Arnd Bergmann <arnd@...db.de>

The newly added flush_dcache_folio() causes a harmless warning that
turns into a build failure with CONFIG_WERROR:

arch/microblaze/include/asm/cacheflush.h:77:13: error: 'flush_dcache_folio' defined but not used [-Werror=unused-function]

Mark it as inline to avoid this.

Fixes: 1330c94f53996 ("microblaze: implement the new page table range API")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
