This series extends the kvm-unit-tests/arm[64] framework to support smp.
A break down of the patches is as follows
01-02: prepare general framework for smp use
03-06: arm/arm64 fixups not 100% related to this series,
but need to post some time...
07-09: add thread_info (for per-thread data) and suck some global
data into it
10-11: add cpumask support (for per-cpu data) and suck some more
global data in
12: add arm64 simple spinlock implementation
13-14: add some PSCI support
15-16: further prep for smp_boot_secondary
17: finally add smp_boot_secondary
18: as usual, add a selftest to make sure it all works
These patches are also available here:
