Subject: [GIT PULL] percpu fixes for 3.4-rc5

Hello, Linus.

Please pull from the following branch to recieve two fixes for percpu
allocator.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git for-3.4-fixes

One adds missing KERN_CONT on split printk()s and the other makes
percpu allocator avoid using PMD_SIZE as atom_size on x86_32.  Using
PMD_SIZE led to vmalloc area exhaustion on certain configurations
(x86_32 android) and the only cost of using PAGE_SIZE instead is
static percpu area not being aligned to large page mapping.

Tejun Heo (2):
      percpu: use KERN_CONT in pcpu_dump_alloc_info()
      percpu, x86: don't use PMD_SIZE as embedded atom_size on 32bit
