powerpc: Override __ALIGN and __ALIGN_STR macros
In a subsequent patch, we would want to annotate powerpc assembly functions with SYM_FUNC_START_LOCAL macro. This macro depends on __ALIGN macro. The default expansion of __ALIGN macro is: #define __ALIGN .align 4,0x90 So, override __ALIGN and __ALIGN_STR macros to use the same alignment as that of the existing _GLOBAL macro. Also, do not pad with 0x90, because repeated 0x90s are not a nop or trap on powerpc. Tested-by: Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com> Reviewed-by: Naveen N.
