Increase cmd_per_lun to allow more I/Os in progress per device,
particularly for NVMe's. The Hyper-V host side can handle the
higher count with no issues.

Update the algorithm in storvsc_do_io to look for a channel
starting with the current CPU + 1 and wrap around (within the
current NUMA node). This spreads VMbus interrupts more evenly
across CPUs. Previous code always started with first CPU in
the current NUMA node, skewing the interrupt load to th

It is very unlikely for CPUs to get offlined when we run on Hyper-V as
we have a protection in vmbus module which prevents it when we have any
VMBus devices assigned. This, however, may change in future if an option
to reassign an already active channel will be added. It is also possible
to run wi
When we run nested KVM on Hyper-V guests we need to update masterclocks for
all guests when L1 migrates to a host with different TSC frequency.
Implement the procedure in the following way:
- Pause all guests.
- Tell our host (Hyper-V) to stop emulating TSC accesses.
- Update our gtod copy, recompu
Currently, KVM is able to work in 'masterclock' mode passing
PVCLOCK_TSC_STABLE_BIT to guests when the clocksource we use on the host
is TSC. When running nested on Hyper-V we normally use a different one:
TSC page which is resistant to TSC frequency changes on event like L1
migration. Add support
This is going to be used from KVM code where we need to get both
TSC and TSC page value.
Nobody is supposed to use the function when Hyper-V code is compiled out,
just BUG().

Hyper-V supports Live Migration notification. This is supposed to be used
in conjunction with TSC emulation: when we are migrated to a host with
different TSC frequency for some short period host emulates our accesses
to TSC and sends us an interrupt to notify about the event. When we're

Hyper-V reenlightenment interrupts arrive when the VM is migrated, we're
not supposed to see many of them. However, it may be important to know
