The patch titled memory hotplug: make alloc_bootmem_section() has been removed from the -mm tree. Its filename was memory-hotplug-make-alloc_bootmem_section.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: memory hotplug: make alloc_bootmem_section() From: Yasunori Goto <y-goto@xxxxxxxxxxxxxx> alloc_bootmem_section() can allocate specified section's area. This is used for usemap to keep same section with pgdat by later patch.
