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
