x86: shrink __ALIGN and __ALIGN_STR definitions
Impact: cleanup 1) .p2align 4 and .align 16 are the same meaning (until a.out format for i386 is used which is not our case for CONFIG_X86_ALIGNMENT_16 anyway) 2) having 15 as max allowed bytes to be skipped does not make sense on modulo 16 Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> LKML-Reference: <20090309171951.GE9945@localhost> [ small cleanup, use __stringify(), etc. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>
