Subject: [PATCH v2 0/6] memblock: cleanup memblock_free interface

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.

I agree with Christophe that doing step by step makes the thing easier to
review, so the patches 3-6 do the actual cleanup step by step.

This time I used stricter coccinelle scripts so that only straightforward
uses would get converted.

There still a couple of (void *) castings for the cases when a virtual
address has unsigned long type rather than a pointer type, like e.g
initrd_start.

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

Juergen and Shahab, I didn't keep your Reviewed-by because the patches are
a bit different this time.

v2:
* split changes into several patches
* use stricter coccinelle scripts

Mike Rapoport (6):
  arch_numa: simplify numa_distance allocation
  xen/x86: free_p2m_page: use memblock_free_ptr() to free a virtual pointer
  memblock: drop memblock_free_early_nid() and memblock_free_early()
  memblock: stop aliasing __memblock_free_late with memblock_free_late
  memblock: rename memblock_free to memblock_phys_free
  memblock: use memblock_free for freeing virtual pointers
