Subject: [PATCH] jump_label: Fix unaligned traps on sparc.
Date: Sat, 23 Oct 2010 11:06:24 -0700 (PDT) [thread overview]
Message-ID: <20101023.110624.226758370.davem@davemloft.net> (raw)
The vmlinux.lds.h knobs to emit the __jump_table section in the main
kernel image takes care to align the section, but this doesn't help
for the __jump_table section that gets emitted into modules.
Fix the resulting lack of section alignment by explicitly specifying
it in the assembler.
