Subject: [PATCH v2 0/3] cma: factor out allocation logic from __cma_declare_contiguous_nid

From: "Mike Rapoport (Microsoft)" <rppt@...nel.org>

Hi,

We've discussed earlier that HIGHMEM related logic is spread all over
__cma_declare_contiguous_nid().

These patches decouple it into helper functions.

v2 changes:
* use already declared 'ret' rather than 'err' (Oscar)
* rather than factor out only HIGHMEM allocation move all of the
  allocation logic to a helper (Oscar and David)
* add Acks, thanks!

Mike Rapoport (Microsoft) (3):
  cma: move __cma_declare_contiguous_nid() before its usage
  cma: split resrvation of fixed area into a helper function
  cma: move allocation from HIGHMEM to a helper function
