[Xen-devel] [PATCH v3 15/18] bug/x86/arm: Align bug_frames sections.

Most of the WARN_ON or BUG_ON sections are properly aligned on x86. However on ARM and on x86 assembler the macros don't include any aligment information - hence they end up being the default byte granularity. On ARM32 it is paramount that the aligment is word-size (4) otherwise if one tries to
