[PATCH 2/2] memory-hotplug: cleanup: removing the arch specific functions without any implementation
From: Lin Feng <hidden>
Date: 2013-01-16 08:15:34
Also in:
linux-mm, linux-s390, lkml, sparclinux
Subsystem:
linux for powerpc (32-bit and 64-bit), s390 architecture, sparc + ultrasparc (sparc/sparc64), the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Heiko Carstens, Vasily Gorbik, Alexander Gordeev, "David S. Miller", Andreas Larsson, Linus Torvalds
From: Michal Hocko <redacted> After introducing CONFIG_HAVE_BOOTMEM_INFO_NODE Kconfig option, the related arch specific functions become confusing, remove them. Guys who want to implement memory-hotplug feature on such archs for this part should look into register_page_bootmem_info_node() and flesh out from top to end.
