fa3d5b85c6 Drivers: hv: Support the newly introduced KVP messages in the driver
Support the newly defined KVP message types. It turns out that the host
pushes a set of standard key value pairs as soon as the guest opens the KVP channel.
Since we cannot handle these tuples until the user level daemon loads up, defer
reading the KVP channel until the user level daemon is launched.

2640335438 drivers: hv: kvp: Cleanup the kernel/user protocol
Now, cleanup the user/kernel KVP protocol by using the same structure
definition that is used for host/guest KVP protocol. This simplifies the code.

0720a06a75 NLS: improve UTF8 -> UTF16 string conversion routine
The utf8s_to_utf16s conversion routine needs to be improved.  Unlike
its utf16s_to_utf8s sibling, it doesn't accept arguments specifying
the maximum length of the output buffer or the endianness of its
16-bit output.

This patch (as1501) adds the two missing arguments, and adjusts the
only two places in the kernel where the function is called.  A
follow-on patch will add a third caller that does utilize the new
capabilities.

The two conversion routines are still annoyingly inconsistent in the
way they handle invalid byte combinations.  But that's a subject for a
different patch.

da0e96315c hv: rename prep_negotiate_resp() to vmbus_prep_negotiate_resp()
It's a global symbol, so properly prefix it and use the proper EXPORT
value as well.

46a9719136 Staging: hv: move hyperv code out of staging directory
After many years wandering the desert, it is finally time for the
Microsoft HyperV code to move out of the staging directory.  Or at least
the core hyperv bus code, and the utility driver, the rest still have
some review to get through by the various subsystem maintainers.
