Subject: [PATCH 5/7] jump_label: Fix unaligned traps on sparc.
Date: Fri, 29 Oct 2010 15:00:55 -0400 [thread overview]
Message-ID: <20101029190135.983681125@goodmis.org> (raw)
In-Reply-To: 20101029190050.674141729@goodmis.org
[-- Attachment #1: 0005-jump_label-Fix-unaligned-traps-on-sparc.patch --]
[-- Type: text/plain, Size: 1049 bytes --]
From: David Miller <davem@davemloft.net>
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.
