Switch hugemem to use the new hashtable implementation. This reduces the amount of generic unrelated code in the hugemem. This also removes the dymanic allocation of the hash table. The upside is that we save a pointer dereference when accessing the hashtable, but we lose 8KB if CONFIG_TRANSPARENT_HUGEPAGE is enabled but the processor doesn't support hugepages. Signed-off-by:

Compaction uses the ALIGN macro incorrectly with the migrate scanner by adding pageblock_nr_pages to a PFN. It happened to work when initially implemented as the starting PFN was also aligned but with caching restarts and isolating in smaller chunks this is no longer always true. The impact is that the migrate scanner scans outside its current pageblock. As pfn_valid() is still checked properly it does not cause any failure and the impact of the bug is that in some cases it will scan more than necessary when it crosses a page boundary but by no more than COMPACT_CLUSTER_MAX. It is highly unlikely this is even measurable but it's still wrong so this patch addresses the problem. Signed-off-by:

When ex-KSM pages are faulted from swap cache, the fault handler is not capable of re-establishing anon_vma-spanning KSM pages. In this case, a copy of the page is created instead, just like during a COW break. These freshly made copies are known to be exclusive to the faulting VMA and there is no reason to go look for this page in parent and sibling processes during rmap operations. Use page_add_new_anon_rmap() for these copies. This also puts them on the proper LRU lists and marks them SwapBacked, so we can get rid of doing this ad-hoc in the KSM copy code. Signed-off-by:

The restart logic for when reclaim operates back to back with compaction is currently applied on the lruvec level. But this does not make sense, because the container of interest for compaction is a zone as a whole, not the zone pages that are part of a certain memory cgroup. Negative impact is bounded. For one, the code checks that the lruvec has enough reclaim candidates, so it does not risk getting stuck on a condition that can not be fulfilled. And the unfairness of hammering on one particular memory cgroup to make progress in a zone will be amortized by the round robin manner in which reclaim goes through the memory cgroups. Still, this can lead to unnecessary allocation latencies when the code elects to restart on a hard to reclaim or small group when there are other, more reclaimable groups in the zone. Move this logic to the zone level and restart reclaim for all memory cgroups in a zone when compaction requires more free pages from it. [akpm@linux-foundation.org: no need for min_t] Signed-off-by:

Reclaim pressure balance between anon and file pages is calculated through a tuple of numerators and a shared denominator. Exceptional cases that want to force-scan anon or file pages configure the numerators and denominator such that one list is preferred, which is not necessarily the most obvious way: fraction[0] = 1; fraction[1] = 0; denominator = 1; goto out; Make this easier by making the force-scan cases explicit and use the fractionals only in case they are calculated from reclaim history.

Johannes Weiner authored
A swappiness of 0 has a slightly different meaning for global reclaim (may swap if file cache really low) and memory cgroup reclaim (never swap, ever). In addition, global reclaim at highest priority will scan all LRU lists equal to their size and ignore other balancing heuristics. UNLESS swappiness forbids swapping, then the lists are balanced based on recent reclaim effectiveness. UNLESS file cache is running low, then anonymous pages are force-scanned. This (total mess of a) behaviour is implicit and not obvious from the way the code is organized. At least make it apparent in the code flow and document the conditions. It will be it easier to come up with sane semantics later. Signed-off-by:

Johannes Weiner authored
In certain cases (kswapd reclaim, memcg target reclaim), a fixed minimum amount of pages is scanned from the LRU lists on each iteration, to make progress. Do not make this minimum bigger than the respective LRU list size, however, and save some busy work trying to isolate and reclaim pages that are not there. Empty LRU lists are quite common with memory cgroups in NUMA environments because there exists a set of LRU lists for each zone for each memory cgroup, while the memory of a single cgroup is expected to stay on just one node. The number of expected empty LRU lists is thus memcgs * (nodes - 1) * lru types Each attempt to reclaim from an empty LRU list does expensive size comparisons between lists, acquires the zone's lru lock etc. Avoid that.

Pull x86 mm changes from Peter Anvin: "This is a huge set of several partly interrelated (and concurrently developed) changes, which is why the branch history is messier than one would like. The *really* big items are two humonguous patchsets mostly developed by Yinghai Lu at my request, which completely revamps the way we create initial page tables. In particular, rather than estimating how much memory we will need for page tables and then build them into that memory -- a calculation that has shown to be incredibly fragile -- we now build them (on 64 bits) with the aid of a "pseudo-linear mode" -- a #PF handler which creates temporary page tables on demand. This has several advantages: 1. It makes it much easier to support things that need access to data very early (a followon patchset uses this to load microcode way early in the kernel startup). 2. It allows the kernel and all the kernel data objects to be invoked from above the 4 GB limit. This allows kdump to work on very large systems. 3. It greatly reduces the difference between Xen and native (Xen's equivalent of the #PF handler are the temporary page tables created by the domain builder), eliminating a bunch of fragile hooks. The patch series also gets us a bit closer to W^X. Additional work in this pull is the 64-bit get_user() work which you were also involved with, and a bunch of cleanups/speedups to __phys_addr()/__pa()." * 'x86-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (105 commits) x86, mm: Move reserving low memory later in initialization x86, doc: Clarify the use of asm("%edx") in uaccess.h x86, mm: Redesign get_user with a __builtin_choose_expr hack x86: Be consistent with data size in getuser.S x86, mm: Use a bitfield to mask nuisance get_user() warnings x86/kvm: Fix compile warning in kvm_register_steal_time() x86-32: Add support for 64bit get_user() x86-32, mm: Remove reference to alloc_remap() x86-32, mm: Remove reference to resume_map_numa_kva() x86-32, mm: Rip out x86_32 NUMA remapping code x86/numa: Use __pa_nodebug() instead x86: Don't panic if can not alloc buffer for swiotlb mm: Add alloc_bootmem_low_pages_nopanic() x86, 64bit, mm: hibernate use generic mapping_init x86, 64bit, mm: Mark data/bss/brk to nx x86: Merge early kernel reserve for 32bit and 64bit x86: Add Crash kernel low reservation x86, kdump: Remove crashkernel range find limit for 64bit memblock: Add memblock_mem_size() x86, boot: Not need to check setup_header version for setup_data ... -
