sched/preempt: Take away preempt_enable_no_resched() from modules

2014-01-13T12:47:37Z

Discourage drivers/modules to be creative with preemption. Sadly all is implemented in macros and inline so if they want to do evil they still can, but at least try and discourage some.

sched: Extract the basic add/sub preempt_count modifiers

2013-09-25T12:07:54Z

Rewrite the preempt_count macros in order to extract the 3 basic preempt_count value modifiers: __preempt_count_add() __preempt_count_sub() and the new: __preempt_count_dec_and_test() And since we're at it anyway, replace the unconventional $op_preempt_count names with the more conventional preempt_count_$op. Since these basic operators are equivalent to the previous _notrace() variants, do away with the _notrace() versions.

maccess,probe_kernel: Make write/read src const void *

2011-05-25T23:56:23Z

The functions probe_kernel_write() and probe_kernel_read() do not modify the src pointer. Allow const pointers to be passed in without the need of a typecast.

maccess,probe_kernel: Allow arch specific override probe_kernel_(read|write)

2010-01-07T17:58:36Z

Some archs such as blackfin, would like to have an arch specific probe_kernel_read() and probe_kernel_write() implementation which can fall back to the generic implementation if no special operations are needed.

uaccess: fix parameters inversion for __copy_from_user_inatomic()

2008-09-16T05:44:46Z

[PATCH] probe_kernel_address() needs to do set_fs()

2006-12-07T16:39:34Z

probe_kernel_address() purports to be generic, only it forgot to select KERNEL_DS, so it presently won't work right on all architectures. Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mm: pagefault_{disable,enable}()

2006-12-07T16:39:21Z

Introduce pagefault_{disable,enable}() and use these where previously we did manual preempt increments/decrements to make the pagefault handler do the atomic thing. Currently they still rely on the increased preempt count, but do not rely on the disabled preemption, this might go away in the future. (NOTE: the extra barrier() in pagefault_disable might fix some holes on machines which have too many registers for their own good) [heiko.carstens@de.ibm.com: s390 fix] Signed-off-by: Peter Zijlstra Acked-by: Nick Piggin Cc: Martin Schwidefsky Signed-off-by: Heiko Carstens Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
