Hello,

(Resending due to a typo in an e-mail address that caused LAKML to reject the mails. Sorry about the noise.)

This patch set reworks Ezequiel Garcia's previous fix [1] of an out of vmalloc space bug on PXA2[57]x platforms caused by an attempt to map the start of physical uncached outside of the vmalloc space.

This first three patches perform a couple of cleanups, and the last patch fixes the problem. I've decided to map the memory at address 0xfe000000 to minimize changes to the code, but this causes a bit of fragmentation of vmalloc space. I could map it to the very end of vmalloc space (0xfef00000)
instead if preferred, which would involve replacing a mov by an ldr in pxa2[57]x_finish_suspend and pm_enter_standby_start.

I've tested the patch set on a PXA270-based system.

Thank you.

MAINTAINERS lists three maintainers for the PXA architecture, and two git trees that seem to be either dead or even deleted. Who picks up patches for PXA ? Should I send a pull request ?

If no one else answers, then just send a pull request to the ARM-SOC team (arm at kernel.org) and CC the linux-arm-kernel mailing list.

What ever happened to this?
