2005-10-29[PATCH] mm: page fault handlers tidyupHugh Dickins
Impose a little more consistency on the page fault handlers do_wp_page, do_swap_page, do_anonymous_page, do_no_page, do_file_page: why not pass their arguments in the same order, called the same names? break_cow is all very well, but what it did was inlined elsewhere: easier to compare if it's brought back into do_wp_page. do_file_page's fallback to do_no_page dates from a time when we were testing pte_file by using it wherever possible: currently it's peculiar to nonlinear vmas, so just check that. BUG_ON if not? Better not, it's probably page table corruption, so just show the pte: hmm, there's a pte_ERROR macro, let's use that for do_wp_page's invalid pfn too. Hah! Someone in the ppc64 world noticed pte_ERROR was unused so removed it: restored (and say "pud" not "pmd" in its pud_ERROR).

2005-10-29[PATCH] mm: unlink_file_vma, remove_vmaHugh Dickins
Divide remove_vm_struct into two parts: first anon_vma_unlink plus unlink_file_vma, to unlink the vma from the list and tree by which rmap or vmtruncate might find it; then remove_vma to close, fput and free. The intention here is to do the anon_vma_unlink and unlink_file_vma earlier, in free_pgtables before freeing any page tables: so we can be sure that any page tables traversed by rmap and vmtruncate are stable (and other, ordinary cases are stabilized by holding mmap_sem). This will be crucial to traversing pgd,pud,pmd without page_table_lock. But testing the split-out patch showed that lifting the page_table_lock is symbiotically necessary to make this change - the lock ordering is wrong to move those unlinks into free_pgtables while it's under ptlock.

2005-10-29[PATCH] mm: vm_stat_account unshackledHugh Dickins
The original vm_stat_account has fallen into disuse, with only one user, and only one user of vm_stat_unaccount. It's easier to keep track if we convert them all to __vm_stat_account, then free it from its __shackles.

2005-10-29[PATCH] Convert mempolicies to nodemask_tAndi Kleen
The NUMA policy code predated nodemask_t so it used open coded bitmaps. Convert everything to nodemask_t. Big patch, but shouldn't have any actual behaviour changes (except I removed one unnecessary check against node_online_map and one unnecessary BUG_ON) Signed-off-by: "Andi Kleen" <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-29[PATCH] add sem_is_read/write_locked()Rik Van Riel
Add sem_is_read/write_locked functions to the read/write semaphores, along the same lines of the *_is_locked spinlock functions. The swap token tuning patch uses sem_is_read_locked; sem_is_write_locked is added for completeness.

2005-10-29[ARM] 3061/1: cleanup the XIP link address messNicolas Pitre
Patch from Nicolas Pitre Since vmlinux.lds.S is preprocessed, we can use the defines already present in asm/memory.h (allowed by patch #3060) for the XIP kernel link address instead of relying on a duplicated Makefile hardcoded value, and also get rid of its dependency on awk to handle it at the same time. While at it let's clean XIP stuff even further and make things clearer in head.S with a nice code reduction.

2005-10-29[ARM] 3060/1: allow constants found in asm/memory.h to be used in asm codeNicolas Pitre
Patch from Nicolas Pitre This patch allows for assorted type of cleanups by letting assembly code use the same set of defines for constant values and avoid duplicated definitions that might not always be in sync, or that might simply be confusing due to the different names for the same thing.

2005-10-29The type of sum in csum_tcpudp_nofold is "unsigned int", so when we assignRalf Baechle
to it in an asm() block, and we're running on a system with 64-bit registers, it is vitally important that we sign extend it correctly before returning to C. Otherwise the stray high bits will be preserved into csum_fold, and on the SB-1 processor, 32-bit arithmetic on a non sign-extended register will yield surprising results. This caused incorrect checksums in some UDP packets for NFS root. The problem was mild when using a 10.0.1.x IP address, but severe when using 192.168.1.x.
