The 64bit\ntoolchain has never had problems with incorrect mmap permissions (the 32bit\nhas, thats why we need to retain the workaround).\n\nWith these fixes as well as a gcc fix from Alan Modra (that was recently\ncommitted) 64bit apps work as expected.\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\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.
