x86_64: Use read and write crX in .c files

2007-07-22T18:03:37Z

This patch uses the read and write functions provided at system.h for control registers instead of writting raw assembly over and over again in .c files. Functions to manipulate cr2 and cr8 were provided, as they were lacking. Also, removed some extra space after closing brackets Signed-off-by: Glauber de Oliveira Costa Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] sched: sched_cacheflush is now unused

2007-07-19T19:28:35Z

Since Ingo's recent scheduler rewrite which was merged as commit 0437e109e1841607f2988891eaa36c531c6aa6ac sched_cacheflush is unused. Signed-off-by: Ralf Baechle Signed-off-by: Ingo Molnar

rename thread_info to stack

2007-05-09T19:30:56Z

This finally renames the thread_info field in task structure to stack, so that the assumptions about this field are gone and archs have more freedom about placing the thread_info structure. Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.

x86: create asm/cmpxchg.h

2007-05-08T18:15:20Z

i386: Rearrange the cmpxchg code to allow atomic.h to get it without needing to include system.h. This kills warnings in the UML build from atomic.h about implicit declarations of cmpxchg symbols. The i386 build presumably isn't seeing this because a separate inclusion of system.h is covering it over. The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in system.h for the benefit of generic code which expects cmpxchg there. Meanwhile, atomic.h includes cmpxchg.h. This causes no noticable damage to the i386 build. x86_64: Move cmpxchg into its own header. atomic.h already included system.h, so this is changed to include cmpxchg.h. This is purely cleanup - it's not fixing any warnings - so if the x86_64 system.h isn't considered as cleanup-worthy as i386, then this can be dropped. It causes no noticable damage to the x86_64 build. uml: The i386 and x86_64 cmpxchg patches require an asm-um/cmpxchg.h for the UML build.
