[Xen-devel] [PATCH v2 05/21] memblock: emphasize that memblock_alloc_range() returns a physical address

[Mike Rapoport <rppt@xxxxxxxxxxxxx>]

Rename memblock_alloc_range() to memblock_phys_alloc_range() to emphasize
that it returns a physical address.
While on it, remove the 'enum memblock_flags' parameter from this function
as its only user anyway sets it to MEMBLOCK_NONE, which is the default for
the most of memblock allocations.
