Subject[PATCH v2 0/5] PPC32/ioremap: Use memblock API to check for RAM
Date
v1: https://www.spinics.net/lists/linux-mm/msg145939.html

This patchset makes it possible to allocate MMIO ranges that are between
the two RAM chunks on the Wii, MEM1 and MEM2, not only with ioremap
(which previously worked through a hack) but also with kernel/resource.c.

Changes in v2:
- I added back the p < virt_to_phys(high_memory) check in
__ioremap_caller because high memory should be allocatable through
ioremap
- I expanded the commit messages a bit

Jonathan Neuschäfer (5):
powerpc: mm: Simplify page_is_ram by using memblock_is_memory
powerpc: mm: Use memblock API for PPC32 page_is_ram
powerpc/mm/32: Use page_is_ram to check for RAM
powerpc: wii: Don't rely on the reserved memory hack
powerpc/mm/32: Remove the reserved memory hack
