Subject: [PATCH] percpu: include irqflags.h for raw_local_irq_save()
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.2/older/patches-5.2.10-rt5.tar.xz
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.
