[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.

[PATCH] include/asm-*/bitops.h: fix more "~0UL >> size" typos

2006-02-03T16:32:02Z

"[PATCH] m68knommu: fix find_next_zero_bit in bitops.h" fixed a typo in m68knommu implementation of find_next_zero_bit(). grep(1) shows that cris, frv, h8300, v850 are also affected.

[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] cris: fix KSTK_EIP

2006-01-12T17:08:58Z

cris KSTK_EIP looked for pt_regs at the right offset but from the wrong place - forgotten ->thread_info Signed-off-by: Al Viro Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Generic ioctl.h

2006-01-10T16:01:34Z

Most arches copied the i386 ioctl.h. Combine them into a generic header. Signed-off-by: Brian Gerst 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.

[PATCH] mutex subsystem, add atomic_xchg() to all arches

2006-01-09T23:59:17Z

add atomic_xchg() to all the architectures. Needed by the new mutex code. Signed-off-by: Ingo Molnar Signed-off-by: Arjan van de Ven

[PATCH] consolidate asm/futex.h

2006-01-09T04:13:39Z

Most of the architectures have the same asm/futex.h. This consolidates them into asm-generic, with the arches including it from their own asm/futex.h. In the case of UML, this reverts the old broken futex.h and goes back to using the same one as almost everyone else.
