The PAL call that should tell the kernel the size of the\n      virtual address space isn\u0027t implemented for the simulator, so\n      the kernel uses the default 50.  This is addressed separately\n      in dc90e95f310f4f821c905b2aec8e9449bb3270fa\n\n      2.  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"

      "message": "[IA64] Percpu quicklist for combined allocator for pgd/pmd/pte.\n\nThis patch introduces using the quicklists for pgd, pmd, and pte levels\nby combining the alloc and free functions into a common set of routines.\nThis greatly simplifies the reading of this header file.\n\nThis patch is simple but necessary for large numa configurations.\nIt simply ensures that only pages from the local node are added to a\ncpus quicklist.  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"

Since ia64 does need a special case, restore to\nppc64 the special case of skipping them.\n\nThe ia64 hugetlb case has been broken since pgd_addr_end went in, though it\nprobably appeared to work okay if you just had one such area; in fact it\u0027s\nbeen broken much longer if you consider a long munmap spanning from another\nregion into the hugetlb region.\n\nIn the ia64 hugetlb region, more virtual address bits are available than in\nthe other regions, yet the page tables are structured the same way: the page\nat the bottom is larger.  Here we need to scale down each addr before passing\nit to the standard free_pgd_range.  Was about to write a hugely_scaled_down\nmacro, but found htlbpage_to_page already exists for just this purpose.  Fixed\noff-by-one in ia64 is_hugepage_only_range.\n\nUninline free_pgd_range to make it available to ia64.

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"
