lib/scatterlist.o needed by a module only - link it in unconditionally

2008-02-08T23:33:33+00:00

lib/scatterlist.c is needed by drivers/media/video/videobuf-dma-sg.c, and
we would like to be able to use the latter without PCI too, for example, on
PXA270 ARM CPU.  It is then possible to create a configuration with
CONFIG_BLOCK=n, where only module code will need scatterlist.c.  Therefore
it must be in obj-y.

iommu sg: add IOMMU helper functions for the free area management

2008-02-05T17:44:11+00:00

This adds IOMMU helper functions for the free area management.  These
functions take care of LLD's segment boundary limit for IOMMUs.  They would be
useful for IOMMUs that use bitmap for the free area management.

[LIB]: Introduce struct pcounter

2008-01-28T22:54:39+00:00

This just generalises what was introduced by Eric Dumazet for the struct proto
inuse field in 286ab3d46058840d68e5d7d52e316c1f7e98c59f:

    [NET]: Define infrastructure to keep 'inuse' changes in an efficent SMP/NUMA way.

Please look at the comment in there to see the rationale.

SG: Move functions to lib/scatterlist.c and add sg chaining allocator helpers

2008-01-28T09:05:27+00:00

Manually doing chained sg lists is not trivial, so add some helpers
to make sure that drivers get it right.

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

2007-11-15T02:45:37+00:00

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.

Fix cpusets update_cpumask

2007-10-19T18:53:41+00:00

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

2007-10-17T15:42:45+00:00

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

Move uevent specific logic from the core into kobject_uevent.c, which
does no longer require to link the unused string array if hotplug

Introduce CONFIG_CHECK_SIGNATURE

2007-08-23T02:52:45+00:00

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.
