Hi All, This series primarly adds KVM selftests support for powerpc (64-bit, BookS, radix MMU).
This patch series is originally Nick's work. I have mainly only rebased it on the latest upstream tree. Since the rebase required few changes to all four patches, I have dropped the earlier Acked-by from Michael Ellerman. Since the last series was posted three years ago [1], I am resetting the version to RFC and posting an early version (few tests still pending) for getting any early review comments. BTW, I ran this on P9 (PowerNV) with radix and haven't found any regressions so far. Note that I am planning to run this selftests with different configurations as well on PowerPC and will share the test results soon. This rebase was done as part of a larger effort to improve the selftests infrastructure for Linux on PowerPC tree. Thanks to Harsh and Maddy for their help on this.
