[PATCH 02/16] powerpc: override ALIGN() and ALIGN_STR() macros

From: Sathvika Vasireddy <hidden>
Date: 2022-08-08 11:50:14
Also in: linux-arm-kernel, lkml
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Michael Ellerman, Linus Torvalds

Since we need an alignment of 4 bytes, override
__ALIGN() and __ALIGN_STR() accordingly.
