Subject: xtensa: merge stack alignment definitions
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=e94dc6bbdf29787a5ddb01c143a074c31e427dc7;p=linux.git

xtensa: merge stack alignment definitions

xtensa currently has two different definitions for stack alignment.
Replace it with single definition usable in both C and assembly.
