[PATCH V2 0/3] MSHV: Redesign memory deposit logic

[Mukesh R <mrathor@linux.microsoft.com>]

This small series redesigns the memory deposit logic when Linux runs on
Hyper-V hypervisor as a privileged VM, the second patch explains why.
The series is split in three patches, the first patch renames the
functions to _old and that makes the 2 main patch much easier and nicer
to review. Last patch just removes the *_old functions from first patch.

Thanks,
-Mukesh

V2:
 o Enhance comments
 o In case of contiguous and failure, don't goto err_free_dep_pages but
   just return also. It should not happen, but if it does, hypevisor will
   throw error.

V1:
 o Remove hv_alloc_contig_pages() and make contiguous allocation part of
   hv_alloc_dep_pages(), thus getting rid of the kmalloc.
 o Instead of stubbing out functions, rename them to *_old.
