drivers/staging/zcache/zcache-main.c: fix build
flush_dcache_page() takes a page*, not a void*. It breaks ia64.
Remove this and another unused function. Warnings remain:
drivers/staging/zcache/zcache-main.c: In function '__check_disable_cleancache':
drivers/staging/zcache/zcache-main.c:1837: warning: return from incompatible pointer type
drivers/staging/zcache/zcache-main.c: In function '__check_disable_frontswap':
drivers/staging/zcache/zcache-main.c:1838: warning: return from incompatible pointer type
drivers/staging/zcache/zcache-main.c: In function '__check_disable_frontswap_ignore_nonactive':
drivers/staging/zcache/zcache-main.c:1842: warning: return from incompatible pointer type
