On ppc64/aarch64 Linux can be set to use Large pages, so the PAGE_SIZE isn't build-time constant anymore. Define it through _SC_PAGESIZE. There are different sizes for a page on ppc64: : #if defined(CONFIG_PPC_256K_PAGES) : #define PAGE_SHIFT 18 : #elif defined(CONFIG_PPC_64K_PAGES) : #define PAGE_SHIFT 16 : #elif defined(CONFIG_PPC_16K_PAGES) : #define PAGE_SHIFT 14 : #else : #define PAGE_SHIFT 12 : #endif And on aarch64 there are default sizes and possibly someone can set his own PAGE_SHIFT: : config ARM64_PAGE_SHIFT : int : default 16 if ARM64_64K_PAGES : default 14 if ARM64_16K_PAGES : default 12 On the downside - each time we need PAGE_SIZE, we're doing libc function call on aarch64/ppc64.
