  KVM: PPC: Introduce KVM_CAP_PPC_HTM (2016-08-01 19:42:06 +0200)

----------------------------------------------------------------
- ARM: GICv3 ITS emulation and various fixes.  Removal of the old
VGIC implementation.

- s390: support for trapping software breakpoints, nested virtualization
(vSIE), the STHYI opcode, initial extensions for CPU model support.

- MIPS: support for MIPS64 hosts (32-bit guests only) and lots of cleanups,
preliminary to this and the upcoming support for hardware virtualization
extensions.

- x86: support for execute-only mappings in nested EPT; reduced vmexit
latency for TSC deadline timer (by about 30%) on Intel hosts; support for
more than 255 vCPUs.

- PPC: bugfixes.

The ugly bit is the conflicts.  A couple of them are simple conflicts due
to 4.7 fixes, but most of them are with other trees. There was definitely
too much reliance on Acked-by here.  Some conflicts are for KVM patches
where _I_ gave my Acked-by, but the worst are for this pull request's
patches that touch files outside arch/*/kvm.  KVM submaintainers should
probably learn to synchronize better with arch maintainers, with the
latter providing topic branches whenever possible instead of Acked-by.
This is what we do with arch/x86.  And I should learn to refuse pull
requests when linux-next sends scary signals, even if that means that
submaintainers have to rebase their branches.

Anyhow, here's the list:

- arch/x86/kvm/vmx.c: handle_pcommit and EXIT_REASON_PCOMMIT was removed
by the nvdimm tree.  This tree adds handle_preemption_timer and
EXIT_REASON_PREEMPTION_TIMER at the same place.  In general all mentions
of pcommit have to go.

There is also a conflict between a stable fix and this patch, where the
stable fix removed the vmx_create_pml_buffer function and its call.

- virt/kvm/kvm_main.c: kvm_cpu_notifier was removed by the hotplug tree.
This tree adds kvm_io_bus_get_dev at the same place.

- virt/kvm/arm/vgic.c: a few final bugfixes went into 4.7 before the
file was completely removed for 4.8.

- include/linux/irqchip/arm-gic-v3.h: this one is entirely our fault;
this is a change that should have gone in through the irqchip tree and
pulled by kvm-arm.  I think I would have rejected this kvm-arm pull
request.  The KVM version is the right one, except that it lacks
GITS_BASER_PAGES_SHIFT.

- arch/powerpc: what a mess.  For the idle_book3s.S conflict, the KVM
tree is the right one; everything else is trivial.  In this case I am
not quite sure what went wrong.  The commit that is causing the mess
(fd7bacbca47a, "KVM: PPC: Book3S HV: Fix TB corruption in guest exit
path on HMI interrupt", 2016-05-15) touches both arch/powerpc/kernel/
and arch/powerpc/kvm/.  It's large, but at 396 insertions/5 deletions
I guessed that it wasn't really possible to split it and that the 5
deletions wouldn't conflict.  That wasn't the case.

- arch/s390: also messy.  First is hypfs_diag.c where the KVM tree
moved some code and the s390 tree patched it.  You have to reapply the
relevant part of commits 6c22c9863760, plus all of e030c1125eab, to
arch/s390/kernel/diag.c.  Or pick the linux-next conflict
resolution from http://marc.info/?l=kvm&m=146717549531603&w=2.
Second, there is a conflict in gmap.c between a stable fix and 4.8.
The KVM version here is the correct one.

I have pushed my resolution at refs/heads/merge-20160802 (commit
3d1f53419842) at git://git.kernel.org/pub/scm/virt/kvm/kvm.git.
