[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.

[SPARC]: sys_newfstatat --> sys_fstatat64

[SPARC]: Wire up sys_unshare().

Also, the Solaris syscall table is sized differrently, and does not go beyond entry 255, so trim off the excess entries. Signed-off-by: David S. Miller

[SPARC]: Add support for *at(), ppoll, and pselect syscalls.

2006-01-19T10:42:49Z

This also includes by necessity _TIF_RESTORE_SIGMASK support, which actually resulted in a lot of cleanups. The sparc signal handling code is quite a mess and I should clean it up some day. Signed-off-by: David S. Miller

[SPARC]: sparc32 needs PROMDEV_{I,O}RSC defines too.

[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

[PATCH] sched: add cacheflush() asm

2006-01-12T17:08:49Z

Add per-arch sched_cacheflush() which is a write-back cacheflush used by the migration-cost calibration code at bootup time. Signed-off-by: Ingo Molnar Cc: Nick Piggin Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mutex subsystem, add default include/asm-*/mutex.h files

2006-01-09T23:59:19Z

add the per-arch mutex.h files for the remaining architectures. We default to asm-generic/mutex-dec.h, because that performs quite well on most arches. Arches that do not have atomic decrement/increment instructions should switch to mutex-xchg.h instead. Arches can also provide their own implementation for the mutex fastpath primitives.
