[PATCH 0/6] Miscellaneous nommu fixes

Hello,

This set of patches is a series of fixes for kernels built without
CONFIG_MMU selected. It seems that this isn't a particularly popular
choice amongst users of mainline kernels, but I was feeling brave and
gave it a go.

The first patch is already in the patch system as 7337/1 but is unlikely
to be merged unless it can be shown to work correctly. I tried the latest
Codesourcery / Mentor uclinux GDB but that doesn't appear to issue the
relevant ptrace requests:

http://lists.infradead.org/pipermail/linux-arm-kernel/2012-February/086219.html

If anybody has a working uclinux environment, it would *make my day* if
they could take GDB for a spin.

The second patch has been picked up by Andrew Morton from the kexec list.

The remaining patches are largely straightforward with the exception of
the CPU suspend changes. I actually managed to test this with a rather
weird and wonderful configuration, although this was using software
models which tend to hide some of the issues you may experience with
real hardware.

All feedback welcome.

Will
