[PATCH v2 0/2] restrict /dev/mem to idle io memory ranges

[Dan Williams]

Changes since v1 [1]:

1/ Introduce ARCH_HAS_DEVMEM_IS_ALLOWED to flag archs where
   CONFIG_STRICT_DEVMEM will compile (Ingo)

2/ Drop "default y" for s390 (Heiko)

3/ Fix iomem_is_exclusive() return value in the
   CONFIG_IO_STRICT_DEVMEM=y case.
