6e8087a4fa Staging: hv: storvsc: Fix a bug in create_bounce_buffer()
Set the length field of the scatter gather elements correctly when we create
the bounce buffer. When we use the bounce buffer for a "write" operation,
the act of copying to the bounce buffer, correctly deals with this issue.
However, on the "read" side, the current code was not correctly setting
the buffer length. Fix this bug. Note that when we copy from the bounce
buffer (for the read case), the amount we copy is controlled by the original
scatter gather list given to the driver.

ce3e301c44 Staging: hv: storvsc: Implement per device memory pools
The current code implemented a per-HBA memory pool mechanism. For IDE disks
managed by this driver, there is a one to one correspondance between the
block device and the associated virtual HBA and since currently only IDE devices
can be the boot device, this addressed the deadlock issues that were raised during
the review process. This patch implements a per-lun memory pool mechanism.

76e5f8135d Staging: hv: util: Fix a bug in kvp implementation
The host gurantees that there can be only one kvp transaction active
against the guest. So, the transaction active state is needed only to
protect against spurious user level calls. The current code had a race
condition where the guest could prematurely return because the previous
transaction state was not cleared - this state was being cleared after
sending the response to the host and there was a window where the host
could notify the guest of a new transaction before the transaction active
state was properly set.
Also deal with the case when the user mode component
does not respond in a timely fashion correctly.
I would like to thank Long Li <longli@microsoft.com>

c411f17daf Staging: hv: mousevsc: Now cleanup mousevsc_remove()
Now, cleanup mousevsc_remove(). The mouse driver once initialized only
receives data from the host. So, by closing the channel first in the
unload path, we can properly deal with inflight packets. So, we don't need
the machinery for managing the life-cycle of the mousevsc_dev object.
Get rid of the unnecessary code.
