| |
Hello, Linus.
Percpu changes for v3.8. Nothing exciting here either. Joonsoo's is almost cosmetic. Cyrill's patch fixes "percpu_alloc" early kernel param handling so that the kernel doesn't crash when the parameter is specified w/o any argument.
git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git for-next
Thanks.

Joonsoo Kim (1): percpu: make pcpu_free_chunk() use pcpu_mem_free() instead of kfree()
