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 arch/x86/kernel/setup_percpu.c | 14 +++++++++++++- mm/percpu.c | 10 +++++----- 2 files changed, 18 insertions(+), 6 deletions(-) Thanks. -- tejun
