[PATCH] add asm-generic/mman.h

2006-02-15T23:32:22Z

Make new MADV_REMOVE, MADV_DONTFORK, MADV_DOFORK consistent across all arches. The idea is to make it possible to use them portably even before distros include them in libc headers. Move common flags to asm-generic/mman.h Signed-off-by: Michael S. Tsirkin Cc: Roland Dreier Cc: Badari Pulavarty Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] madvise MADV_DONTFORK/MADV_DOFORK

2006-02-15T00:09:34Z

Currently, copy-on-write may change the physical address of a page even if the user requested that the page is pinned in memory (either by mlock or by get_user_pages). This happens if the process forks meanwhile, and the parent writes to that page. As a result, the page is orphaned: in case of get_user_pages, the application will never see any data hardware DMA's into this page after the COW. In case of mlock'd memory, the parent is not getting the realtime/security benefits of mlock. In particular, this affects the Infiniband modules which do DMA from and into user pages all the time. This patch adds madvise options to control whether memory range is inherited across fork. Useful e.g. for when hardware is doing DMA from/into these pages. Could also be useful to an application wanting to speed up its forks by cutting large areas out of consideration. Signed-off-by: Michael S.

[PARISC] New syscalls (inotify, *at, pselect6/ppoll, migrate_pages)

2006-01-30T05:53:14Z

Wire up some new syscalls that have been merged upstream, o inotify o openat et al o pselect6/ppoll o migrate_pages Signed-off-by: Kyle McMartin

[PARISC] Arch-specific compat signals

2006-01-23T01:57:42Z

Add enough arch-specific compat signals code to enable parisc64 to compile and boot out of the mainline tree. There are likely still many dragons here, but this is a start to squashing the last big difference between the mainline tree and the parisc-linux tree. The remaining bugs can be squashed as they come up. Signed-off-by: Kyle McMartin

[PARISC] Add CONFIG_DEBUG_RODATA to protect read-only data

2006-01-23T01:26:54Z

Add the parisc version of the "mark rodata section read only" patches. Based on code from and Signed-off-by Arjan van de Ven , Ingo Molnar , Andi Kleen , Andrew Morton , Linus Torvalds . Signed-off-by: Helge Deller Signed-off-by: Kyle McMartin

[PARISC] atomic64 support

2006-01-23T01:26:44Z

Implement atomic64_t so atomic_long_t works on parisc. Also clean up some of the coding style in atomic.h, and make sure ATOMIC_INIT is cast properly. Signed-off-by: Kyle McMartin

[PARISC] Drop unused do_check_pgt_cache()

2006-01-23T01:26:37Z

Drop the unused do_check_pgt_cache routine from mm/init.c and its prototype in asm/pgalloc.h Signed-off-by: Helge Deller Signed-off-by: Kyle McMartin

[PARISC] Remove unnecessary extern declarations from asm/pci.h

2006-01-23T01:26:34Z

Remove two unnecessary extern declarations from asm/pci.h. They collide with what gcc4.0 assumed was static (and should be static). Found by Joel Soete. Signed-off-by: Grant Grundler Signed-off-by: Kyle McMartin

[PARISC] Use kzalloc and other janitor-style cleanups

2006-01-23T01:26:31Z

Helge, o Convert a bunch of kmalloc/memset uses to kzalloc. o pci.c: Add some __read_mostly annotations. o pci.c: Move constant pci_post_reset_delay to asm/pci.h o grfioctl.h: Add A4450A to comment of CRT_ID_VISUALIZE_EG. o Add some consts to perf.c/perf_images.h Matthew, o sticore.c: Add some consts to suppress compile warnings.

[PATCH] death of get_thread_info/put_thread_info

2006-01-12T17:08:59Z

{get,put}_thread_info() were introduced in 2.5.4 and never had been called by anything in the tree. Signed-off-by: Al Viro Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
