[PATCH 0/5] powerpc: lmb related bug fix & cleanups

[Michael Ellerman]

The first patch in this series should fix the crash we're seeing on iSeries
of late, since Benh's n_addrs patch. It should go upstream asap.

The second is a preventative patch, to make finding a similar bug in the future
easier.

The third patch implements an idea I floated a while back, which is to make
lmb_alloc() panic on failure. Currently all[1] callers either panic or don't
check the return value.

The other two are just cleanups of lmb.h

All booted on pSeries LPAR & iSeries, built for G5 and pmac32.

[1] except for careful_allocation(), which my patch caters for.
