Subject: [PATCH 09/12] irqstat: Move declaration into asm-generic/hardirq.h
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.17-rt32.tar.xz
Move the declaration of the irq_cpustat per cpu variable to
asm-generic/hardirq.h and remove the now empty linux/irq_cpustat.h header.
