Fix type warnings in arch/arc/mm/cache.c.
../arch/arc/mm/cache.c: In function 'flush_anon_page': ../arch/arc/mm/cache.c:1062:55: warning: passing argument 2 of '__flush_dcache_page' makes integer from pointer without a cast [-Wint-conversion] __flush_dcache_page((phys_addr_t)page_address(page), page_address(page)); ^~~~~~~~~~~~~~~~~~ ../arch/arc/mm/cache.c:1013:59: note: expected 'long unsigned int' but argument is of type 'void *' void __flush_dcache_page(phys_addr_t paddr, unsigned long vaddr) ~~~~~~~~~~~~~~^~~~~
