nommu: don't need get_unmapped_area() for NOMMU

2010-01-16T20:15:40+00:00

get_unmapped_area() is unnecessary for NOMMU as no-one calls it. Signed-off-by: David Howells Acked-by: Al Viro Cc: Greg Ungerer Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mm: move sys_mmap_pgoff from util.c

2009-12-30T20:23:27+00:00

Move sys_mmap_pgoff() from mm/util.c to mm/mmap.c and mm/nommu.c, where we'd expect to find such code: especially now that it contains the MAP_HUGETLB handling. Revert mm/util.c to how it was in 2.6.32. This patch just ignores MAP_HUGETLB in the nommu case, as in 2.6.32, whereas 2.6.33-rc2 reported -ENOSYS. Perhaps validate_mmap_request() should reject it with -EINVAL? Add that later if necessary. Signed-off-by: Hugh Dickins Signed-off-by: Linus Torvalds

mm: clean up get_user_pages_fast() documentation

2009-06-17T02:47:30+00:00

Move more documentation for get_user_pages_fast into the new kerneldoc comment. Add some comments for get_user_pages as well. Also, move get_user_pages_fast declaration up to get_user_pages. It wasn't there initially because it was once a static inline function.

slab: document kzfree() zeroing behavior

2009-06-01T06:22:46+00:00

As suggested by Alan Cox, document the fact that kzfree() can zero out a great deal more memory than the what the user requested from kmalloc(). Cc: Alan Cox Signed-off-by: Pekka Enberg

Merge branch 'linus' into tracing/core

2009-05-07T09:17:34+00:00

Merge reason: tracing/core was on a .30-rc1 base and was missing out on on a handful of tracing fixes present in .30-rc5-almost. Signed-off-by: Ingo Molnar

tracing/events: move trace point headers into include/trace/events

2009-04-15T02:05:43+00:00

Impact: clean up Create a sub directory in include/trace called events to keep the trace point headers in their own separate directory. Only headers that declare trace points should be defined in this directory.

tracing: create automated trace defines

2009-04-14T16:57:28+00:00

This patch lowers the number of places a developer must modify to add new tracepoints. The current method to add a new tracepoint into an existing system is to write the trace point macro in the trace header with one of the macros TRACE_EVENT, TRACE_FORMAT or DECLARE_TRACE, then they must add the same named item into the C file with the macro DEFINE_TRACE(name) and then add the trace point. This change cuts out the needing to add the DEFINE_TRACE(name). Every file that uses the tracepoint must still include the trace/.h file, but the one C file must also add a define before the including of that file. #define CREATE_TRACE_POINTS #include This will cause the trace/mytrace.h file to also produce the C code necessary to implement the trace point. Note, if more than one trace/.h is used to create the C code it is best to list them all together. #define CREATE_TRACE_POINTS #include #include #include Thanks to Mathieu Desnoyers and Christoph Hellwig for coming up with the cleaner solution of the define above the includes over my first design to have the C code include a "special" header. This patch converts sched, irq and lockdep and skb to use this new method.
