Here are some bug fix patches for physical memory hot-remove. All these
patches are based on the latest -mm tree.

And patch1 and patch3 are very important.
patch1: free compound pages when freeing memmap, otherwise the kernel
will panic the next time memory is hot-added.
patch3: the old way of freeing pagetable pages was wrong. We should never
split larger pages into small ones.
Hi Tang,
I remember your big physical memory hot-remove patchset has already
merged by Andrew, but where I can find it? Could you give me git tree
address?
Andrew tree is also mirrored into a git tree.
http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary
It contains only Memory management patches on top of the last major
release (since-.X.Y branch).
Hi Michal,
I'm not sure I got your meaning. :)
In http://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git akpm,
I can find the following commit.
