Subject[RFC 1/6] powerpc:/drc Define interface to acquire arch-specific drc info
From
Date
Define interface to acquire arch-specific drc info to match against
hotpluggable devices. The current implementation exposes several
pseries-specific dynamic memory properties in generic kernel code.
This patch set provides an interface to pull that code out of the
generic kernel.
