Subject: [GIT PULL] parisc fixes for 2.6.39-rc5

These two fixes contain the agreed fix for our slub panic (agreed with
the mm folks that we'll define SLUB broken in the !NUMA && DISCONTIGMEM
case, which should fix m86k as well) and another buglet that turned up
examining the parisc discontigmem code.

The patches are here:

master.kernel.org:/pub/scm/linux/kernel/git/jejb/parisc-2.6.git#fixes

The short changelog is:

David Rientjes (1):
      [PARISC] set memory ranges in N_NORMAL_MEMORY when onlined

James Bottomley (1):
      [PARISC] slub: fix panic with DISCONTIGMEM
