What appears to be a problem coming from flush_tlb_range(),\nwhich currently unconditionally calls platform_global_tlb_purge().\nFor some of the numa machines in existence today, this function is\nmapped into ia64_global_tlb_purge(), which holds ptcg_lock spin lock\nwhile executing ptc.ga instruction.\n\nHere is a patch that attempt to avoid global tlb purge whenever\npossible.  It will use local tlb purge as much as possible. Though the\nconditions to use local tlb purge is pretty restrictive.  One of the\nside effect of having flush tlb range instruction on ia64 is that\nkernel don\u0027t get a chance to clear out cpu_vm_mask.  On ia64, this mask\nis sticky and it will accumulate if process bounces around.  Thus\ndiminishing the possible use of ptc.l.

      "message": "[PATCH] hugepage: is_aligned_hugepage_range() cleanup\n\nQuite a long time back, prepare_hugepage_range() replaced\nis_aligned_hugepage_range() as the callback from mm/mmap.c to arch code to\nverify if an address range is suitable for a hugepage mapping.\nis_aligned_hugepage_range() stuck around, but only to implement\nprepare_hugepage_range() on archs which didn\u0027t implement their own.\n\nMost archs (everything except ia64 and powerpc) used the same\nimplementation of is_aligned_hugepage_range().  On powerpc, which\nimplements its own prepare_hugepage_range(), the custom version was never\nused.\n\nIn addition, \"is_aligned_hugepage_range()\" was a bad name, because it\nsuggests it returns true iff the given range is a good hugepage range,\nwhereas in fact it returns 0-or-error (so the sense is reversed).\n\nThis patch cleans up by abolishing is_aligned_hugepage_range().  Instead\nprepare_hugepage_range() is defined directly.  Most archs use the default\nversion, which simply checks the given region is aligned to the size of a\nhugepage.  ia64 and powerpc define custom versions.  The ia64 one simply\nchecks that the range is in the correct address space region in addition to\nbeing suitably aligned.  The powerpc version (just as previously) checks\nfor suitable addresses, and if necessary performs low-level MMU frobbing to\nset up new areas for use by hugepages.\n\nNo libhugetlbfs testsuite regressions on ppc64 (POWER5 LPAR).\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Zhang Yanmin \u003cyanmin.zhang@intel.com\u003e\nCc: \"David S.

      "message": "[PATCH] mm: init_mm without ptlock\n\nFirst step in pushing down the page_table_lock.  init_mm.page_table_lock has\nbeen used throughout the architectures (usually for ioremap): not to serialize\nkernel address space allocation (that\u0027s usually vmlist_lock), but because\npud_alloc,pmd_alloc,pte_alloc_kernel expect caller holds it.\n\nReverse that: don\u0027t lock or unlock init_mm.page_table_lock in any of the\narchitectures; instead rely on pud_alloc,pmd_alloc,pte_alloc_kernel to take\nand drop it when allocating a new one, to check lest a racing task already\ndid.  Similarly no page_table_lock in vmalloc\u0027s map_vm_area.\n\nSome temporary ugliness in __pud_alloc and __pmd_alloc: since they also handle\nuser mms, which are converted only by a later patch, for now they have to lock\ndifferently according to whether or not it\u0027s init_mm.\n\nIf sources get muddled, there\u0027s a danger that an arch source taking\ninit_mm.page_table_lock will be mixed with common source also taking it (or\nneither take it).  So break the rules and make another change, which should\nbreak the build for such a mismatch: remove the redundant mm arg from\npte_alloc_kernel (ppc64 scrapped its distinct ioremap_mm in 2.6.13).\n\nExceptions: arm26 used pte_alloc_kernel on user mm, now pte_alloc_map; ia64\nused pte_alloc_map on init_mm, now pte_alloc_kernel; parisc had bad args to\npmd_alloc and pte_alloc_kernel in unused USE_HPPA_IOREMAP code; ppc64\nmap_io_page forgot to unlock on failure; ppc mmu_mapin_ram and ppc64 im_free\ntook page_table_lock for no good reason.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

In arch/ia64/mm/init.c there\u0027s code to calcualte the size\n      of the VMLPT based on the number of implemented virtual address\n      bits and the page size.  It checks to see if the VMLPT base\n      address overlaps the top of the mapped region, but this check\n      doesn\u0027t allow for the address space hole, and in fact will\n      never trigger.\n\nHere\u0027s an alternative test and panic, that I think is more accurate.\n\nSigned-off-by: Peter Chubb \u003cpeterc@gelato.unsw.edu.au\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n"

This prevents the trapping of pages on a remote nodes\nquicklist by starting a process, touching a large number of pages to\nfill pmd and pte entries, migrating to another node, and then unmapping\nor exiting.  With those conditions, the pages get trapped and if the\nmachine has more than 100 nodes of the same size, the calculation of\nthe pgtable high water mark will be larger than any single node so page\ntable cache flushing will never occur.\n\nI ran lmbench lat_proc fork and lat_proc exec on a zx1 with and without\nthis patch and did not notice any change.\n\nOn an sn2 machine, there was a slight improvement which is possibly\ndue to pages from other nodes trapped on the test node before starting\nthe run.  I did not investigate further.\n\nThis patch shrinks the quicklist based upon free memory on the node\ninstead of the high/low water marks.  I have written it to enable\npreemption periodically and recalculate the amount to shrink every time\nwe have freed enough pages that the quicklist size should have grown.\nI rescan the nodes zones each pass because other processess may be\ndraining node memory at the same time as we are adding.\n\nSigned-off-by: Robin Holt \u003cholt@sgi.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n"

      "message": "[PATCH] freepgt: free_pgtables use vma list\n\nRecent woes with some arches needing their own pgd_addr_end macro; and 4-level\nclear_page_range regression since 2.6.10\u0027s clear_page_tables; and its\nlong-standing well-known inefficiency in searching throughout the higher-level\npage tables for those few entries to clear and free: all can be blamed on\nignoring the list of vmas when we free page tables.\n\nReplace exit_mmap\u0027s clear_page_range of the total user address space by\nfree_pgtables operating on the mm\u0027s vma list; unmap_region use it in the same\nway, giving floor and ceiling beyond which it may not free tables.  This\nbrings lmbench fork/exec/sh numbers back to 2.6.10 (unless preempt is enabled,\nin which case latency fixes spoil unmap_vmas throughput).\n\nBeware: the do_mmap_pgoff driver failure case must now use unmap_region\ninstead of zap_page_range, since a page table might have been allocated, and\ncan only be freed while it is touched by some vma.\n\nMove free_pgtables from mmap.c to memory.c, where its lower levels are adapted\nfrom the clear_page_range levels.  (Most of free_pgtables\u0027 old code was\nactually for a non-existent case, prev not properly set up, dating from before\nhch gave us split_vma.) Pass mmu_gather** in the public interfaces, since we\nmight want to add latency lockdrops later; but no attempt to do so yet, going\nby vma should itself reduce latency.\n\nBut what if is_hugepage_only_range?  Those ia64 and ppc64 cases need careful\nexamination: put that off until a later patch of the series.\n\nWhat of x86_64\u0027s 32bit vdso page __map_syscall32 maps outside any vma?\n\nAnd the range to sparc64\u0027s flush_tlb_pgtables?  It\u0027s less clear to me now that\nwe need to do more than is done here - every PMD_SIZE ever occupied will be\nflushed, do we really have to flush every PGDIR_SIZE ever partially occupied? \nA shame to complicate it unnecessarily.\n\nSpecial thanks to David Miller for time spent repairing my ceilings.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
