Subject: [PATCH 0/3] cma: factor out HIGMEM 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.

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
