Subject: [PATCH] ARM: Allow kernel unaligned accesses on ARMv6+
processors

Recent gcc versions generate unaligned accesses by default on ARMv6

and

later processors. This patch ensures that the SCTLR.A bit is always
cleared on such processors to avoid kernel traping before
alignment_init() is called.

It worked great, thanks Catalin. I'd love to see a solution merged in
the mainline and this seems reasonable.
I'm being pushed to newer tools which require a solution.
