Subject: [PATCH 0/3] memblock: cleanup memblock_free interface

From: Mike Rapoport <rppt@...ux.ibm.com>

Hi,

Following the discussion on [1] this is the fix for memblock freeing APIs
mismatch. 

The first patch is a cleanup of numa_distance allocation in arch_numa I've
spotted during the conversion.
The second patch is a fix for Xen memory freeing on some of the error
paths.

The core change is in the third patch that makes memblock_free() a
counterpart of memblock_alloc() and adds memblock_phys_alloc() to be a
counterpart of memblock_phys_alloc().

Since scripts/get_maintainer.pl returned more than 100 addresses I've
trimmed the distribution list only to the relevant lists.
