2008-05-11Add new 'cond_resched_bkl()' helper functionLinus Torvalds
It acts exactly like a regular 'cond_resched()', but will not get optimized away when CONFIG_PREEMPT is set. Normal kernel code is already preemptable in the presense of CONFIG_PREEMPT, so cond_resched() is optimized away (see commit 02b67cc3ba36bdba351d6c3a00593f4ec550d9d3 "sched: do not do cond_resched() when CONFIG_PREEMPT"). But when wanting to conditionally reschedule while holding a lock, you need to use "cond_sched_lock(lock)", and the new function is the BKL equivalent of that. Also make fs/locks.c use it.

2008-05-11i2c: Match dummy devices by typeJean Delvare
As the old driver_name/type matching scheme is going away soon, change the dummy device mechanism to use the new matching scheme. This has the downside that dummy i2c clients can no longer choose their name, they'll all appear as "dummy" in sysfs and in log messages. I don't think it is a problem in practice though, as there is little reason to use these i2c clients to log messages. Signed-off-by: Jean Delvare <khali@linux-fr.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev * 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: [libata] revert new check-ready Status register logic
2008-05-10BKL: revert back to the old spinlock implementationLinus Torvalds
The generic semaphore rewrite had a huge performance regression on AIM7 (and potentially other BKL-heavy benchmarks) because the generic semaphores had been rewritten to be simple to understand and fair. The latter, in particular, turns a semaphore-based BKL implementation into a mess of scheduling. The attempt to fix the performance regression failed miserably (see the previous commit 00b41ec2611dc98f87f30753ee00a53db648d662 'Revert "semaphore: fix"'), and so for now the simple and sane approach is to instead just go back to the old spinlock-based BKL implementation that never had any issues like this. This patch also has the advantage of being reported to fix the regression completely according to Yanmin Zhang, unlike the semaphore hack which still left a couple percentage point regression. As a spinlock, the BKL obviously has the potential to be a latency issue, but it's not really any different from any other spinlock in that respect. We do want to get rid of the BKL asap, but that has been the plan for several years. These days, the biggest users are in the tty layer (open/release in particular) and Alan holds out some hope: "tty release is probably a few months away from getting cured - I'm afraid it will almost certainly be the very last user of the BKL in tty to get fixed as it depends on everything else being sanely locked." so while we're not there yet, we do have a plan of action.

2008-05-10Move ACCESS_ONCE() to <linux/compiler.h>Linus Torvalds
It actually makes much more sense there, and we do tend to need it for non-RCU usage too. Moving it to <linux/compiler.h> will allow some other cases that have open-coded the same logic to use the same helper function that RCU has used. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-05-08netfilter: nf_conntrack_sip: restrict RTP expect flushing on error to last ↵Patrick McHardy
request Some Inovaphone PBXs exhibit very stange behaviour: when dialing for example "123", the device sends INVITE requests for "1", "12" and "123" back to back. The first requests will elicit error responses from the receiver, causing the SIP helper to flush the RTP expectations even though we might still see a positive response. Note the sequence number of the last INVITE request that contained a media description and only flush the expectations when receiving a negative response for that sequence number.

2008-05-06libata: improve post-reset device ready testTejun Heo
Some controllers (jmb and inic162x) use 0x77 and 0x7f to indicate that the device isn't ready yet. It looks like they use 0xff if device presence is detected but connection isn't established. 0x77 or 0x7f after connection is established and use the value from signature FIS after receiving it. This patch implements ata_check_ready(), which takes TF status value and determines whether the port is ready or not considering the above and other conditions, and use it in @check_ready() functions. This is safe as both 0x77 and 0x7f aren't valid ready status value even though they have BSY bit cleared. This fixes hot plug detection failures which can be triggered with certain drives if they aren't already spun up when the data connector is hot plugged. Tested on sil, sil24, ahci (jmb/ich), piix and inic162x combined with eight drives from all major vendors. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-05-02USB: add Cypress c67x00 OTG controller core driverPeter Korsgaard
This patch add the core driver for the c67x00 USB OTG controller. The core driver is responsible for the platform bus binding and creating either USB HCD or USB Gadget instances for each of the serial interface engines on the chip. This driver does not directly implement the HCD or gadget behaviours; it just controls access to the chip.

2008-05-02USB: Add the USB 2.0 extension descriptor.Sarah Sharp
This device descriptor was added by the recent USB Link Power Management (LPM) ECN. It indicates whether the USB device supports LPM. This descriptor is grouped under a Binary Device Object Store (BOS) descriptor. Update the BOS comments to indicate any USB device (not just wireless USB devices) can implement BOS descriptors.

Rather than faking up some geometry, allow the backend to push the disk geometry via virtio pci config option. Keep the old geo code around for compatibility.
