Tejun Heo f891125028 x86-64, NUMA: Revert NUMA affine page table allocation ... This patch reverts NUMA affine page table allocation added by commit 1411e0ec31 (x86-64, numa: Put pgtable to local node memory). The commit made an undocumented change where the kernel linear mapping strictly follows intersection of e820 memory map and NUMA configuration. If the physical memory configuration has holes or NUMA nodes are not properly aligned, this leads to using unnecessarily smaller mapping size which leads to increased TLB pressure. For details, http://thread.gmane.org/gmane.linux.kernel/1104672 Patches to fix the problem have been proposed but the underlying code needs more cleanup and the approach itself seems a bit heavy handed and it has been determined to revert the feature for now and come back to it in the next developement cycle. http://thread.gmane.org/gmane.linux.kernel/1105959 As init_memory_mapping_high() callsites have been consolidated since the commit, reverting is done manually. Also, the RED-PEN comment in arch/x86/mm/init.c is not restored as the problem no longer exists with memblock based top-down early memory allocation.
