Robert Jarzmik 649de51b88 [ARM] 5027/1: Fixed random memory corruption on pxa suspend cycle.
Each time a pxa type cpu went in suspend, a portion of
kmalloc memory was corrupted.
The issue was an incorrect length allocation introduced by
the commit 711be5ccfe for
the save registers array (=> overflow).
