A few words about the patch submission process though: - Please add a version number (v2, v3...) to your patch series. It helps the reviewers keeping track of where we are in the review process - Add a change log to your cover letter. Clearly state what changed. Otherwise, reviewers have to start diffing between patches, which becomes quickly messy, specially considering the lack of versioning. - Make sure your patches are part of an email thread starting with your cover letter. This helps reviewers to locate the various patches in a busy Inbox, and to follow the evolution of a discussion. Use of "git send-email" is recommended for posting the patch series. That being said, I'm off to review the actual patches... ;-) Thanks, M. > Mario Smarduch (5): > add ARMv7 HYP API to flush VM TLBs without address param > live migration support for initial write protect of VM to manage > dirty pages > live migration support for VM dirty log management > add 2nd stage page fault handling during live migration > add kvm_arch glogal live migration variable > > arch/arm/include/asm/kvm_asm.h | 1 + > arch/arm/include/asm/kvm_host.h | 7 ++ > arch/arm/kvm/arm.c | 75 ++++++++++++- > arch/arm/kvm/interrupts.S | 5 + > arch/arm/kvm/mmu.c | 220 ++++++++++++++++++++++++++++++++++++++- > 5 files changed, 305 insertions(+), 3 deletions(-) -- Jazz is not dead.
