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"
