This patch series base on ishimatsu's patch series. You can get it here: http://www.spinics.net/lists/linux-acpi/msg36804.html The patches can remove following things: - page table of removed memory If you find lack of function for physical memory hot-remove, please let me know. Note: * The patch "remove memory info from list before freeing it" is being disccussed in other thread. But for testing the patch series, the patch is needed. So I added the patch as [PATCH 0/8]. * You need to apply ishimatsu's patch series first before applying this patch series.
