lib: move bitmap.o from lib-y to obj-y.

2007-11-15T02:45:37Z

mac80211 has a reference to __bitmap_empty() via bitmap_empty(). In lib/bitmap.c this is flagged with an EXPORT_SYMBOL(), but this is ultimately ineffective due to bitmap.o being linked in lib-y, resulting in: ERROR: "__bitmap_empty" [net/mac80211/mac80211.ko] undefined! Moving bitmap.o to obj-y fixes this up. Signed-off-by: Paul Mundt Cc: "John W. Linville" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Fix cpusets update_cpumask

2007-10-19T18:53:41Z

Cause writes to cpuset "cpus" file to update cpus_allowed for member tasks: - collect batches of tasks under tasklist_lock and then call set_cpus_allowed() on them outside the lock (since this can sleep). - add a simple generic priority heap type to allow efficient collection of batches of tasks to be processed without duplicating or missing any tasks in subsequent batches. - make "cpus" file update a no-op if the mask hasn't changed - fix race between update_cpumask() and sched_setaffinity() by making sched_setaffinity() post-check that it's not running on any cpus outside cpuset_cpus_allowed().

lib: floating proportions

2007-10-17T15:42:45Z

Given a set of objects, floating proportions aims to efficiently give the proportional 'activity' of a single item as compared to the whole set. Where 'activity' is a measure of a temporal property of the items. It is efficient in that it need not inspect any other items of the set in order to provide the answer. It is not even needed to know how many other items there are. It has one parameter, and that is the period of 'time' over which the 'activity' is measured.

Driver core: exclude kobject_uevent.c for !CONFIG_HOTPLUG

2007-10-12T21:51:06Z

Move uevent specific logic from the core into kobject_uevent.c, which does no longer require to link the unused string array if hotplug is not compiled in. Signed-off-by: Kay Sievers Signed-off-by: Greg Kroah-Hartman

Introduce CONFIG_CHECK_SIGNATURE

2007-08-23T02:52:45Z

Introduce CONFIG_CHECK_SIGNATURE to control inclusion of check_signature() and avoid problems on platforms that don't have readb(). Let the few legacy (ISA || PCI || X86) drivers that need check_signature() select CONFIG_CHECK_SIGNATURE.

lib: move kasprintf to a separate file

2007-07-31T22:39:39Z

kasprintf pulls in kmalloc which proved to be fatal for at least bootimage target on alpha. Move it to a separate file so only users of kasprintf are exposed to the dependency on kmalloc.

add argv_split()

2007-07-18T15:47:40Z

argv_split() is a helper function which takes a string, splits it at whitespace, and returns a NULL-terminated argv vector. This is deliberately simple - it does no quote processing of any kind. [ Seems to me that this is something which is already being done in the kernel, but I couldn't find any other implementations, either to steal or replace. Keep an eye out. ] Signed-off-by: Jeremy Fitzhardinge Signed-off-by: Chris Wright Cc: Andrew Morton Cc: Randy Dunlap

CRC7 support

Make check_signature depend on CONFIG_HAS_IOMEM

2007-07-16T23:50:01Z

This should avoid build problems on architectures without a "readb()", that got bitten by check_signature() being uninlined. Noted by Heiko Carstens. Cc: Heiko Carstens Cc: Andrew Morton Signed-off-by: Linus Torvalds
