x86: asm linkage - introduce GLOBAL macro
If the code is time critical and this entry is called from other places we use ENTRY to have it globally defined and especially aligned. Contrary we have some snippets which are size critical. So we use plane ".globl name; name:" directive. Introduce GLOBAL macro for this. Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
