This patch adds trace points in the guest entry and exit code and also
for exceptions handled by the host in kernel mode - hypercalls and page
faults. The new events are added to /sys/kernel/debug/tracing/events
under a new subsystem called kvm_hv.

Patch series adds support for ARMv7 and generic dirty page logging support.
As we try to move towards generic dirty page logging additional logic is moved
to generic code. Initially x86, armv7 KVM_GET_DIRTY_LOG reuses generic
code, shortly followed by armv8 patches.
Testing:
- Generally live
kvm_get_dirty_log() provides generic handling of dirty bitmap, currently reused
by several architectures. Building on that we intrdoduce
kvm_get_dirty_log_protect() adding write protection to mark these pages dirty
for future write access, before next KVM_GET_DIRTY_LOG ioctl call from user
space.
Allow architectures to override the generic kvm_flush_remote_tlbs()
function via HAVE_KVM_ARCH_TLB_FLUSH_ALL. ARMv7 will need this to
provide its own TLB flush interface.

Add support for initial write protection of VM memslots. This patch
series assumes that huge PUDs will not be used in 2nd stage tables, which is
always valid on ARMv7.

Add support to track dirty pages between user space KVM_GET_DIRTY_LOG ioctl
calls. We call kvm_get_dirty_log_protect() function to do most of the work.

This patch adds support for handling 2nd stage page faults during migration,
it disables faulting in huge pages, and dissolves huge pages to page tables.
In case migration is canceled huge pages are used again.

Hi Paolo,
I changed your patch a little to use a Kconfig symbol,
hope that's fine with you.

We now have a generic function that does most of the work of
kvm_vm_ioctl_get_dirty_log, now use it.
