0bf377bbb0 sched: Improve latencies under load by decreasing minimum scheduling granularity
Mathieu reported bad latencies with make -j10 kind of kbuild
workloads - which is mostly caused by us scheduling with a
too coarse granularity.

Reduce the minimum granularity some more, to make sure we
can meet the latency target.

I got the following results (make -j10 kbuild load, average of 3
runs):

 vanilla:

  maximum latency: 38278.9 µs
  average latency:  7730.1 µs

 patched:

  maximum latency: 22702.1 µs
  average latency:  6684.8 µs

Mathieu also measured it:

|
| * wakeup-latency.c (SIGEV_THREAD) with make -j10
|
| - Mainline 2.6.35.2 kernel
|
| maximum latency: 45762.1 µs
| average latency: 7348.6 µs
|
| - With only Peter's smaller min_gran (shown below):
|
| maximum latency: 29100.6 µs
| average latency: 6684.1 µs
|

a41ceb1c17 drm/radeon/kms: fix the colorbuffer CS checker for r300-r500
This commit fixes bogus CS rejection if it contains a sequence
of the following operations:

- Set the color buffer 0. track->cb[i].robj becomes non-NULL.
- Render.
- Set a larger zbuffer than the previously-set color buffer.
- Set a larger scissor area as well.
- Set the color channel mask to 0 to do depth-only rendering.
- Render. --> rejected, because track->cb[i].robj remained non-NULL,
  therefore the conditional checking for the color channel mask and
  friends is not performed, and the larger scissor area causes
  the rejection.

This fixes bugs:
- https://bugs.freedesktop.org/show_bug.cgi?id=29762
- https://bugs.freedesktop.org/show_bug.cgi?id=28869
And maybe some others which seem to look the same.

If possible, this commit should go to stable as well.

ec00efb72f drm/radeon/kms: increase lockup detection interval to 10 sec for r100-r500
One subtest of mesa/demos/gltestperf takes 9 seconds to complete,
so to prevent an unnecessary gpu reset followed by a hardlock, I am
increasing the interval to 10 seconds after which a GPU is considered
in a locked-up state. This is on RV530. However, with a little slower GPU,
we would surpass the interval easily, so this is not a good fix
for gltestperf.

Nevertheless, this commit also fixes hardlocks in the applications which
render at speed of less than 1 frame per second, where the whole frame
consists of only one command stream. The game Tiny & Big is an example.
This bar is now lowered to 0.1 fps.

Now the question comes down to whether we should (often unsuccessfully)
reset the GPU at all? Once we have stable enough drivers, we won't have to.
Has the time come already?

If possible, this commit should go to stable as well.

Destructive load-detection is very expensive and due to failings

551402a30e drm: Fix regression in disable polling e58f637
I broke out my trusty i845 and found a new boot failure, which upon
inspection turned out to be a recursion within:

drm_helper_probe_single_connector_modes() -> drm_helper_hpd_irq_event()
-> intel_crt_detect() -> drm_helper_probe_single_connector_modes()

Calling drm_kms_helper_poll_enable() instead performs the desired
re-initialisation of the polling should the user have toggled the
parameter, without the recursive side-effect.

827e345702 SUNRPC: Fix the NFSv4 and RPCSEC_GSS Kconfig dependencies
The NFSv4 client's callback server calls svc_gss_principal(), which
is defined in the auth_rpcgss.ko

The NFSv4 server has the same dependency, and in addition calls
svcauth_gss_flavor(), gss_mech_get_by_pseudoflavor(),
gss_pseudoflavor_to_service() and gss_mech_put() from the same module.

The module auth_rpcgss itself has no dependencies aside from sunrpc,
so we only need to select RPCSEC_GSS.

fbf3fdd244 statfs() gives ESTALE error
Hi,

An NFS client executes a statfs("file", &buff) call.
"file" exists / existed, the client has read / written it,
but it has already closed it.

user_path(pathname, &path) looks up "file" successfully in the
directory-cache  and restarts the aging timer of the directory-entry.
Even if "file" has already been removed from the server, because the
lookupcache=positive option I use, keeps the entries valid for a while.

nfs_statfs() returns ESTALE if "file" has already been removed from the
server.

If the user application repeats the statfs("file", &buff) call, we
are stuck: "file" remains young forever in the directory-cache.

f2d47d02fd Fix null dereference in call_allocate
In call_allocate we need to reach the auth in order to factor au_cslack
into the allocation.

As of a17c2153d2 "SUNRPC: Move the bound
cred to struct rpc_rqst", call_allocate attempts to do this by
dereferencing tk_client->cl_auth, however this is not guaranteed to be
defined--cl_auth can be zero in the case of gss context destruction (see
rpc_free_auth).

Reorder the client state machine to bind credentials before allocating,
so that we can instead reach the auth through the cred.

eda603f6cd docbook: warn on unused doc entries
When you don't use !E or !I but only !F, then it's very easy to miss
including some functions, structs etc.  in documentation.  To help
finding which ones were missed, allow printing out the unused ones as
warnings.

For example, using this on mac80211 yields a lot of warnings like this:

  Warning: didn't use docs for DOC: mac80211 workqueue
  Warning: didn't use docs for ieee80211_max_queues
  Warning: didn't use docs for ieee80211_bss_change
  Warning: didn't use docs for ieee80211_bss_conf

when generating the documentation for it.

1f3a66889c kernel-doc: ignore case when stripping attributes
There are valid attributes that could have upper case letters, but we
still want to remove, like for example
	__attribute__((aligned(NETDEV_ALIGN)))
as encountered in the wireless code.

6715045ddc PM / Hibernate: Avoid hitting OOM during preallocation of memory
There is a problem in hibernate_preallocate_memory() that it calls
preallocate_image_memory() with an argument that may be greater than
the total number of available non-highmem memory pages.  If that's
the case, the OOM condition is guaranteed to trigger, which in turn
can cause significant slowdown to occur during hibernation.

To avoid that, make preallocate_image_memory() adjust its argument
before calling preallocate_image_pages(), so that the total number of
saveable non-highem pages left is not less than the minimum size of
a hibernation image.  Change hibernate_preallocate_memory() to try to
allocate from highmem if the number of pages allocated by
preallocate_image_memory() is too low.

Modify free_unnecessary_pages() to take all possible memory
allocation patterns into account.

Fix up trivial conflicts due to the same cgroup API thinko fix going
through both Andrew and the networking tree.  However, there were small
differences between the two, with Andrew's version generally being the
nicer one, and the one I merged first. So pick that one.

Conflicts in: include/linux/cgroup.h and kernel/cgroup.c
