Merge branch 'slabh' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc
* 'slabh' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/misc: eeepc-wmi: include slab.h staging/otus: include slab.h from usbdrv.h percpu: don't implicitly include slab.h from percpu.h kmemcheck: Fix build errors due to missing slab.h include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h iwlwifi: don't include iwl-dev.h from iwl-devtrace.h x86: don't include slab.h from arch/x86/include/asm/pgtable_32.h Fix up trivial conflicts in include/linux/percpu.h due to is_kernel_percpu_address() having been introduced since the slab.h cleanup with the percpu_up.c splitup.
