Subject: spapr: Report kvm_irqchip_in_kernel() in 'info pic'
X-Git-Tag: v4.2.0-rc0~70^2~48
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=f041d6af55708a75851bfc4ef1373a565703f976;p=users%2Fdwmw2%2Fqemu.git

spapr: Report kvm_irqchip_in_kernel() in 'info pic'

Unless the machine was started with kernel-irqchip=on, we cannot easily
tell if we're actually using an in-kernel or an emulated irqchip. This
information is important enough that it is worth printing it in 'info
pic'.
