This patchset is Jamie's 1176 patch plus one which sits on top of it and adds support for the v6k features in the 1136r1. (I've included Jamie's patch (a) as a convenience to clean the commit comment up and (b) because of this dependency.)
Specifically the 1136r1 is a v6K core and supports TLS registers, CLREX and half and byte wide exclusives. TLS in particular is needed for recent Linux kernels to boot. (This patch is rowing back a bit from the position I took in earlier discussion of ARM11 feature flags, following some further investigation I did into what cores have what. I haven't bothered to make the WFI instruction actually NOP for 1136r1/1176 as we don't seem to do anything to make it NOP on any core, but we could always add that later if it really seems necessary.) The other point of note about the 1136r1 is that it doesn't have the VA-to-PA registers, so I've added a new feature flag which splits that out of v6K. Ideally I'd like to sneak these patches into 0.15, given the "kernel doesn't boot any more" effect of not supporting the 1136r1 TLS registers...
