Subject: [PATCH 0/4] Low/high memory CMA reservation fixes


This patch set fixes an issue introduced by commits 95b0e655f914 ("ARM: mm:
don't limit default CMA region only to low memory") and f7426b983a6a ("mm:
cma: adjust address limit to avoid hitting low/high memory boundary")
resulting in reserved areas crossing the low/high memory boundary.

Patches 1/4 and 2/4 fix sides issues, with the bulk of the work in patch 3/4.
Patch 4/4 then fixes a printk issue that got me puzzled wondering why memory
reported under the lowmem limit was actually highmem.

This series fixes a v3.18-rc1 regression causing Renesas Koelsch boot
breakages when CMA is enabled.

Laurent Pinchart (4):
  mm: cma: Don't crash on allocation if CMA area can't be activated
  mm: cma: Always consider a 0 base address reservation as dynamic
  mm: cma: Ensure that reservations never cross the low/high mem
  mm: cma: Use %pa to print physical addresses
