Since the current kernel patches haven't enabled the
userspace irqchip support, this patch is not verified yet!

From: Andrew Jones
Move the KVM PMU setup part of fdt_add_pmu_nodes() to
virt_cpu_post_init(), which is a more appropriate location. Now
fdt_add_pmu_nodes() is also named more appropriately, because it
no longer does anything but fdt node creation.
No functional change intended.

Haibo Xu (12):
update Linux headers with new vSPE macros
target/arm/kvm: spe: Add helper to detect SPE when using KVM
target/arm/c
Turn on the spe cpu property by default if host cpu
support it, i.e. we can now do '-cpu max|host' to add
the vSPE, and '-cpu max|host,spe=off' to remove it.
