Subject[PATCH 6/8] jump_label: Fix unaligned traps on sparc.
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.
