Currently we hardwire the number of SLBs to 64, but PAPR says we
should use the ibm,slb-size property to obtain the number of SLB
entries. This uses this property instead of assuming 64. If no
property is found, we assume 64 entries as before.
This soft patches the SLB handler, so it shouldn't change performance
at all.

This updates all the defconfigs in arch/powerpc/configs except iseries

This mostly takes the defaults, except that I turned on tickless idle

support and "Fair group CPU scheduler" for the smaller/embedded platforms.

The commit fa13a5a1f2 (sched: restore
deterministic CPU accounting on powerpc), unconditionally calls
update_process_tick() in system context. In the deterministic
accounting case this is the correct thing to do. However, in the
non-deterministic accounting case we need to not do this, since doing
this results in the time accounted as hardware irq time being
artificially elevated.
Also this collapses 2 consecutive '#ifdef CONFIG_VIRT_CPU_ACCOUNTING'
checks in time.h into one for neatness.

The bootwrapper script currently generates an 'otheros.bld' file in
addition to the file specified by the -o option, when asked to build a
wrapper for PS3.
It should do that in the same directory as the output, not the directory
where the wrapper objects are kept (which might potentially not be
writable when the script runs).
Arguably, the 'otheros.bld' ought to be created with the filename
specified as the -o argument. But that's a more intrusive change.
