active_load_balance() looks susceptible to deadlock when busiest==rq. Without the following patch, my 128-way box deadlocks consistently during boot-time driver init.

Add w83627hf_select_wd_register and w83627hf_unselect_wd_register. Add w83627hf_init to fix initialization problem on certain motherboards. Make ping and disable code return 0 (int) on success. Extract set_heartbeat code to seperate function.

We already have over 200 sign-off lines in the kernel, so let's document the thing, even if discussion may still be on-going.

From: Matt Domsch. The E7205 doesn't have an AGP header, so printing this message is pretty much useless. Also make it KERN_WARNING as well, as it's not really worthy of a KERN_ERR

This option only worked for the amd64 driver. On every other driver, the only thing it did was make it not printk the banner on startup.

This is horribly broken due to a jiffy wrap bug, we never get out of the while loop, preventing booting on a kernel with this driver compiled in. (See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=124495) The warning message there has never been reported in any bug report that google can find, so I'm of the opinion that this driver is trying to be too clever for its own good. Rip out the jiffies logic completely, it should be totally unnecessary.

Arjan noted that in some cases, the build fails. This should fix it up.

From: Jakub Jelinek <jakub@redhat.com> FUTEX_REQUEUE operation has been added to the kernel mainly to improve pthread_cond_broadcast which previously used FUTEX_WAKE INT_MAX op. pthread_cond_broadcast releases internal condvar mutex before FUTEX_REQUEUE operation, as otherwise the woken up thread most likely immediately sleeps again on the internal condvar mutex until the broadcasting thread releases it. Unfortunately this is racy and causes e.g. http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/nptl/tst-cond16.c?rev=1.1&content-type=text/x-cvsweb-markup&cvsroot=glibc to hang on SMP. http://listman.redhat.com/archives/phil-list/2004-May/msg00023.html contains analysis how the hang happens, the problem is if any thread does pthread_cond_*wait in between releasing of the internal condvar mutex and FUTEX_REQUEUE operation, a wrong thread might be awaken (and immediately go to sleep again because it doesn't satisfy conditions for returning from pthread_cond_*wait) while the right thread requeued on the associated mutex and there would be nobody to wake that thread up. The patch below extends FUTEX_REQUEUE operation with something FUTEX_WAIT already uses: FUTEX_CMP_REQUEUE is passed an additional argument which is the expected value of *futex. Kernel then while holding the futex locks checks if *futex != expected and returns -EAGAIN in that case, while if it is equal, continues with a normal FUTEX_REQUEUE operation. If the syscall returns -EAGAIN, NPTL can fall back to FUTEX_WAKE INT_MAX operation which doesn't have this problem, but is less efficient, while in the likely case that nobody hit the (small) window the efficient FUTEX_REQUEUE operation is used.

From: David Gibson <david@gibson.dropbear.id.au> Currently the iSeries virtual ethernet driver has no Tx watchdog timer. This makes it vulnerable to clagging up if the other end of connection is misbehaving - in particular if it is not giving timely hypervisor level acks to our data frams. This patch adds a watchdog timer which resets the connection to any lpar we seem to be having trouble sending to. With any luck the other end might behave better after the reset. If not, this will at least unclag the queue for a while so we can keep talking to the lpars which are behaving correctly. Signed-off-by:

From: Anton Blanchard <anton@samba.org> Based on some profiles we noticed the first vmalloc region was being continually cast out and replaced. All modules end up there so it is one of our hottest segments. This patch bolts the vmalloc region into the second segment. SLB misses on an NFS benchmark were reduced by about 10% with this patch.
