Revision 6f354e5f40f433da98fab4103cd3a0aef1c18bde authored by Russell King on 27 August 2011, 10:37:58 UTC, committed by Russell King on 28 August 2011, 09:39:53 UTC 
ARM: pm: CPU specific code should not overwrite r1 (v:p offset)
 
r1 stores the v:p offset from the CPU invariant resume code, and is
expected to be preserved by the CPU specific code.  Overwriting it is
not a good idea.

We've managed to get away with it on sa1100 platforms because most
happen to have PHYS_OFFSET == PAGE_OFFSET, but that may not be the
case depending on kernel configuration.  So fix this latent bug.

This fixes xsc3 as well which was saving and restoring this register
independently.
