[PATCH] SPARC64: Fix D-cache corruption in mremap

2006-06-22T19:16:11Z

If we move a mapping from one virtual address to another, and this changes the virtual color of the mapping to those pages, we can see corrupt data due to D-cache aliasing. Check for and deal with this by overriding the move_pte() macro. Set things up so that other platforms can cleanly override the move_pte() macro too. This long standing bug corrupts user memory, and in particular has been notorious for corrupting Debian package database files on sparc64 boxes. Signed-off-by: David S.

[PATCH] __get_unaligned() gcc-4 fix

2006-03-08T22:14:00Z

If the 'ptr' is a const, this code cause "assignment of read-only variable" error on gcc 4.x. Use __u64 instead of __typeof__(*(ptr)) for temporary variable to get rid of errors on gcc 4.x. Signed-off-by: Atsushi Nemoto Cc: Ralf Baechle Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[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.

[PATCH] Use atomic64_set for 64-bit case of atomic_long_set

2006-01-15T18:17:07Z

For some reason, the BITS_PER_LONG == 64 case of atomic_long_set was using atomic_set instead of atomic64_set. This does not jive with architectures which use an inline instead of a #define to implement their atomic_set() primitives. Signed-off-by: Kyle McMartin Signed-off-by: Linus Torvalds

Fix mutex_trylock() copy-and-paste bug (x86, x86-64, generic mutex-dec.h)

2006-01-11T23:50:47Z

Noticed by Arjan originally on x86-64, then Ingo on x86, and finally me grepping for it in the generic version. Bad parenthesis nesting. 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 asm-generic/mutex-[dec|xchg|null].h implementations

2006-01-09T23:59:17Z

Add three (generic) mutex fastpath implementations. The mutex-xchg.h implementation is atomic_xchg() based, and should work fine on every architecture. The mutex-dec.h implementation is atomic_dec_return() based - this one too should work on every architecture, but might not perform the most optimally on architectures that have no atomic-dec/inc instructions. The mutex-null.h implementation forces all calls into the slowpath. This is used for mutex debugging, but it can also be used on platforms that do not want (or need) a fastpath at all.

[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.

[PATCH] Kill L1_CACHE_SHIFT_MAX

2006-01-09T04:13:39Z

Kill L1_CACHE_SHIFT from all arches. Since L1_CACHE_SHIFT_MAX is not used anymore with the introduction of INTERNODE_CACHE, kill L1_CACHE_SHIFT_MAX. Signed-off-by: Ravikiran Thirumalai Signed-off-by: Shai Fultheim Signed-off-by: Andi Kleen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
