Hello,

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.

Compared to v3, the patches have been rebased on top of v3.16-rc5. Olof, could
you please pick them up for v3.17 ?

Ezequiel Garcia (1):
  ARM: pxa: Move iotable mapping inside vmalloc region

  ARM: pxa: Don't hardcode addresses and size in map_desc tables
  ARM: pxa: Move UNCACHED_PHYS_0 mapping from generic.c to pxa2[57]x.c
  ARM: pxa: pxa27x: Don't map IMEMC region statically
