John Rose 507279db18 [PATCH] powerpc: reorg RTAS delay code 
This patch attempts to handle RTAS "busy" return codes in a more simple
and consistent manner.  Typical callers of RTAS shouldn't have to
manage wait times and delay calls.

This patch also changes the kernel to use msleep() rather than udelay()
when a runtime delay is necessary.  This will avoid CPU soft lockups
for extended delay conditions.

Jesper Juhl 95eff20feb [PATCH] Don't check pointer for NULL before passing it to kfree [arch/powerpc/kernel/rtas_flash.c] 
Checking a pointer for NULL before passing it to kfree is pointless, kfree
does its own NULL checking of input.

Paul Mackerras f4fcbbe9a7 powerpc: Merge remaining RTAS code 
This moves rtas-proc.c and rtas_flash.c into arch/powerpc/kernel, since
cell wants them as well as pseries (and chrp can use rtas-proc.c too,
at least in principle).  rtas_fw.c is gone, with its bits moved into
rtas_flash.c and rtas.c.
