Return linux-friendly error codes from hypercall helper functions,
which allows them to be used more flexibly.
Introduce hv_result_to_errno() for this purpose, which also handles
the special value U64_MAX returned from hv_do_hypercall().

CONFIG_MSHV_ROOT allows kernels built to run as a normal Hyper-V guest
to exclude the root partition code, which is expected to grow
significantly over time.
This option is a tristate so future driver code can be built as a
(m)odule, allowing faster development iteration cycles.
If CONFIG_MSHV_RO
Running in the root partition is a unique and specialized case that
requires additional code. CONFIG_MSHV_ROOT allows Hyper-V guest kernels
to exclude this code, which is important since significant additional code
specific to the root partition is expected to be added over time.
To do this, chang
Introduce hv_curr_partition_type to store the partition type
as an enum.
Right now this is limited to guest or root partition, but there will
be other kinds in future and the enum is easily extensible.
Set up hv_curr_partition_type early in Hyper-V initialization with
hv_identify_partition_type()
The subject line says v2 but this is actually v3!

Like me you prefer B too, right? If so, please add back
