[PATCH] kernel.h: add IS_PTR_ALIGNED() macro

We often check if a pointer has a specific alignment. Because the '&' (bitwise AND) operator cannot take a pointer for the operand, so we need a cast like, IS_ALIGNED((unsigned long)p, a). IS_PTR_ALIGNED will be useful as a shorthand. Signed-off-by: Masahiro Yamada --- include/linux/kernel.h
