Hi,
this is the new version of [1].
RFC -> v1: - Drop RFC - Addressed feedback from David and Mike - Fence off gigantic pages as there is a cyclic dependency between them and alloc_contig_range - Re-organize the code to make race-window smaller and to put all details in hugetlb code - Drop nodemask initialization. First a node will be tried and then we will back to other nodes containing memory (N_MEMORY). Details in patch#1's changelog - Count new page as surplus in case we failed to dissolve the old page and the new one. Details in patch#1.
I already have a patch that uses the new alloc_and_dissolve() from hotplug code, but I decided to leave that patch out until this patchset is settled.
