| * [PATCH] kill ->put_inodeChristoph Hellwig2008-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And with that last patch to affs killing the last put_inode instance we can finally, after many years of transition kill this racy and awkward interface. (It's kinda funny that even the description in Documentation/filesystems/vfs.txt was entirely wrong..) Also remove a very misleading comment above the defintion of struct super_operations.

* | libata: improve post-reset device ready testTejun Heo2008-05-06
|/ | | | | | | | | | | | | | | | | | | | | | | | 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>

| * sched: add optional support for CONFIG_HAVE_UNSTABLE_SCHED_CLOCKPeter Zijlstra2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this replaces the rq->clock stuff (and possibly cpu_clock()). - architectures that have an 'imperfect' hardware clock can set CONFIG_HAVE_UNSTABLE_SCHED_CLOCK - the 'jiffie' window might be superfulous when we update tick_gtod before the __update_sched_clock() call in sched_clock_tick() - cpu_clock() might be implemented as: sched_clock_cpu(smp_processor_id()) if the accuracy proves good enough - how far can TSC drift in a single jiffie when considering the filtering and idle hooks?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dmitry Adamushko pointed out a logic error in task_wake_up_rt() where we will always evaluate to "true". You can find the thread here: http://lkml.org/lkml/2008/4/22/296 In reality, we only want to try to push tasks away when a wake up request is not going to preempt the current task. So lets fix it. Note: We introduce test_tsk_need_resched() instead of open-coding the flag check so that the merge-conflict with -rt should help remind us that we may need to support NEEDS_RESCHED_DELAYED in the future, too.

The inline function pci_scan_bus refer to functions annotated __devinit - so annotate it __devinit too.

Requesting the shared irq line from another driver result in a spurious interrupt storm which finally disables the interrupt line. I have seen similar behaviour on resume before (the hardware does not work anymore so I can not verify). Change the spurious disable logic to increment the disable depth and mark the interrupt with an extra flag which allows us to reenable the interrupt when a new driver arrives which requests the same irq line. In the worst case this will disable the irq again via the spurious trap, but there is a decent chance that the new driver is the one which can handle the already asserted interrupt and makes the box usable again. Eric Biederman said further: This case also happens on a regular basis in kdump kernels where we deliberately don't shutdown the hardware before starting the new kernel. This patch should reduce the need for using irqpoll in that situation by a small amount.

There is nothing in the API to require this, however, and even I didn't notice when it was violated. So instead, we require the driver to specify what features it supports in a table, we can then move the feature negotiation into the virtio core. The intersection of device and driver features are presented in a new 'features' bitmap in the struct virtio_device. Note that this highlights the difference between Linux unsigned-long bitmaps where each unsigned long is in native endian, and a straight-forward little-endian array of bytes. Drivers can still remove feature bits in their probe routine if they really have to. API changes: - dev->config->feature() no longer gets and acks a feature. - drivers should advertise their features in the 'feature_table' field - use virtio_has_feature() for extra sanity when checking feature bits Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

The virtio config space was originally chosen to be little-endian, because we thought the config might be part of the PCI config space for virtio_pci. It's actually a separate mmio region, so that argument holds little water; as only x86 is currently using the virtio mechanism, we can change this (but must do so now, before the impending s390 merge). API changes: - __virtio_config_val() just becomes a striaght vdev->config_get() call. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

I thought this was good enough for Linux, but it actually isn't, since we don't do UFO in software. So, add separate feature bits for what the host can handle.
