For IA-64 and MIPS, and for any other arch with variable page sizes, you need something like this:
//////////////////////////////////////// extern int getpagesize(void);
#define PAGE_SIZE ((unsigned long)(getpagesize()))
// This is a gcc statement-expression. // You might want the __extension__ keyword. #define PAGE_SHIFT ({ \ int _PAGE_SIZE = PAGE_SIZE; \ (_PAGE_SIZE > 16*1024) \ ? (_PAGE_SIZE == 32*1024) \ ? 15ul \ : 16ul \ : (_PAGE_SIZE == 8*1024) \ ? 13ul \ : (_PAGE_SIZE == 4*1024) \ ? 12ul \ : 14ul \ ; \ }) //////////////////////////////////////////
