ARM: 7425/1: extable: ensure fixup entries are 4-byte aligned
Fixup entries in the kernel exception tables should be 4-byte aligned since we return directly to them when handling a faulting instruction in the kernel. This patch adds the missing align directives to the fixup entries. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
