* sched: fix niced_granularity() shiftIngo Molnar2007-09-05

* sched: fix MC/HT scheduler optimization, without breaking the FUZZ logic.Suresh Siddha2007-09-05
| | | | | | | | | | | | | | | | | | | First fix the check if (*imbalance + SCHED_LOAD_SCALE_FUZZ < busiest_load_per_task) with this if (*imbalance < busiest_load_per_task) As the current check is always false for nice 0 tasks (as SCHED_LOAD_SCALE_FUZZ is same as busiest_load_per_task for nice 0 tasks). With the above change, imbalance was getting reset to 0 in the corner case condition, making the FUZZ logic fail. Fix it by not corrupting the imbalance and change the imbalance, only when it finds that the HT/MC optimization is needed.

I didn't have a great look down the call chains, but this appears to fixes 7 possible use-before uptodate in hfs, 2 in hfsplus, 1 in jfs, a few in ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in block2mtd. All depending on whether the filler is async and/or can return with a !uptodate page. It introduced a wait to read_cache_page, as well as a read_cache_page_async function equivalent to the old read_cache_page without any callers. Switching jffs2_gc_fetch_page to read_cache_page_async for the old behavior makes the deadlocks go away, but maybe reintroduces the use-before-uptodate problem?

The best I can do given the constraints appears to be to have the kernel first look for a superblock that matches both the fsid and the user-specified mount options, and then spawn off a new superblock if that search fails. Note that this is not the same as specifying nosharecache everywhere since nosharecache will never attempt to match an existing superblock.

This makes the frame handling more correct, and tries to clarify the code at the same time so that it's a bit more obvious what is going on.

* | | | | Do not use the ia64 clocksource on non-ia64 architecturesLinus Torvalds2007-08-31

On x86[-64], trying to register this clocksource results in potentially multiple hpet-based clocksources being registered, and if the ia64 one is chosen on x86_64 some users have experienced hangs. Eventually all three architectures may end up using the same code, but that is not the case right now.

In 2.6.23, netdev_priv() == dev->priv, cxgb3 needs a fix. This patch is a partial backport of Dave Miller's changes in the net-2.6.24 git branch. Without this fix, cxgb3 crashes on 2.6.23.

In a HiperSockets environment this disturbs receiving systems when packets are sent on the multicast queue. (E.g. TCP/IP on z/VM issues messages reporting invalid data on the HiperSockets interface.) Qeth will no longer send ARP packets on HiperSockets interface when interface has the NOARP attribute. Signed-off-by: Klaus D.

Make sure qeth_clear_output_buffer() is called only, if the qdio queues have been successfully allocated during initialization of a qeth device.

In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.
