Subject: [PATCH] percpu: include irqflags.h for raw_local_irq_save()
Git-repo: git://git.kernel.org/pub/scm/linux/kernel/git/wagi/linux-stable-rt.git
Git-commit: cdb18bf51ebbf4a6d3b6b9b3bfea641a8b3a5825
Patch-mainline: Queued in subsystem maintainer repository
References: SLE Realtime Extension

The header percpu.h header file is using raw_local_irq_save() but does
not include irqflags.h for its definition. It compiles because the
header file is included via an other header file.
On -RT the build fails because raw_local_irq_save() is not defined.

Include irqflags.h in percpu.h.
