* [PATCH] DMI: move dmi_scan.c from arch/i386 to drivers/firmware/Bjorn Helgaas2006-04-14
| | | | | | | | | | | | | | | | | | dmi_scan.c is arch-independent and is used by i386, x86_64, and ia64. Currently all three arches compile it from arch/i386, which means that ia64 and x86_64 depend on things in arch/i386 that they wouldn't otherwise care about. This is simply "mv arch/i386/kernel/dmi_scan.c drivers/firmware/" (removing trailing whitespace) and the associated Makefile changes. All three architectures already set CONFIG_DMI in their top-level Kconfig files.

* [PATCH] pm: print name of failed suspend functionAndrew Morton2006-04-14

Example: usb_hcd_pci_suspend(): pci_set_power_state+0x0/0x1af() returns -22 pci_device_suspend(): usb_hcd_pci_suspend+0x0/0x11b() returns -22 suspend_device(): pci_device_suspend+0x0/0x34() returns -22 Work-in-progress. It needs lots more suspend_report_result() calls sprinkled everywhere.

* [PATCH] driver core: driver_bind attribute returns incorrect valueRyan Wilson2006-04-14
| | | | | | | | | | | | | | | | | | | | | The manual driver <-> device binding attribute in sysfs doesn't return the correct value on failure or success of driver_probe_device. driver_probe_device returns 1 on success (the driver accepted the device) or 0 on probe failure (when the driver didn't accept the device but no real error occured). However, the attribute can't just return 0 or 1, it must return the number of bytes consumed from buf or an error value. Returning 0 indicates to userspace that nothing was written (even though the kernel has tried to do the bind/probe and failed). Returning 1 indicates that only one character was accepted in which case userspace will re-try the write with a partial string. A more correct version of driver_bind would return count (to indicate the entire string was consumed) when driver_probe_device returns 1 and -ENODEV when driver_probe_device returns 0. This patch makes that change. Signed-off-by: Ryan Wilson <hap9@epoch.ncsc.mil> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] BLOCK: delay all uevents until partition table is scannedKay Sievers2006-04-14
| | | | | | | | | | | | | | | | | | | | [BLOCK] delay all uevents until partition table is scanned Here we delay the annoucement of all block device events until the disk's partition table is scanned and all partition devices are already created and sysfs is populated. We have a bunch of old bugs for removable storage handling where we probe successfully for a filesystem on the raw disk, but at the same time the kernel recognizes a partition table and creates partition devices. Currently there is no sane way to tell if partitions will show up or not at the time the disk device is announced to userspace. With the delayed events we can simply skip any probe for a filesystem on the raw disk when we find already present partitions.

* [PATCH] driver core: safely unbind drivers for devices not on a busAlan Stern2006-04-14
| | | | | | | | | | This patch (as667) changes the __device_release_driver() routine to prevent it from crashing when it runs across a device not on any bus. This seems logical, inasmuch as the corresponding bus_add_device() routine has an explicit check allowing it to accept such devices.

* [PATCH] sysfs: Allow sysfs attribute files to be pollableNeilBrown2006-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | It works like this: Open the file Read all the contents. Call poll requesting POLLERR or POLLPRI (so select/exceptfds works) When poll returns, close the file and go to top of loop. or lseek to start of file and go back to the 'read'. Events are signaled by an object manager calling sysfs_notify(kobj, dir, attr); If the dir is non-NULL, it is used to find a subdirectory which contains the attribute (presumably created by sysfs_create_group). This has a cost of one int per attribute, one wait_queuehead per kobject, one int per open file. The name "sysfs_notify" may be confused with the inotify functionality. Maybe it would be nice to support inotify for sysfs attributes as well? This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action to be pollable Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * [fuse] fix deadlock between fuse_put_super() and request_end()Miklos Szeredi2006-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A deadlock was possible, when the last reference to the superblock was held due to a background request containing a file reference. Releasing the file would release the vfsmount which in turn would release the superblock. Since sbput_sem is held during the fput() and fuse_put_super() tries to acquire this same semaphore, a deadlock results. The chosen soltuion is to get rid of sbput_sem, and instead use the spinlock to ensure the referenced inodes/file are released only once. Since the actual release may sleep, defer these outside the locked region, but using local variables instead of the structure members. This is a much more rubust solution.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically an in-kernel implementation of tee, which uses splice and the pipe buffers as an intelligent way to pass data around by reference. Where the user space tee consumes the input and produces a stdout and file output, this syscall merely duplicates the data inside a pipe to another pipe.

Not changing our real parents is trivially correct because both tasks have the same real parents as they are part of a thread group. Now that we demote the leader to a thread there is no longer any reason to change it's parentage. Not changing our ptrace parents is a user visible change if someone looks hard enough. I don't think user space applications will care or even notice. In the practical and I think common case a debugger will have attached to all of the threads using the same ptrace flags. From my quick skim of strace and gdb that appears to be the case. Which if true means debuggers will not notice a change. Before this point we have already generated a ptrace event in do_exit that reports the leaders pid has died so de_thread is visible to a debugger. Which means attempting to hide this case by copying flags around appears excessive. By not doing anything it avoids all of the weird locking issues between de_thread and ptrace attach, and removes one case from consideration for fixing the ptrace locking. This only addresses Oleg's first concern with ptrace_attach, that of the problems caused by reparenting. Oleg's second concern is essentially a race between ptrace_attach and release_task that causes an oops when we get to force_sig_specific. There is nothing special about de_thread with respect to that race. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

For Tavor, however, the hardware only requires the WQE size to be a multiple of 16, not a power of 2, and the max number of scatter-gather allowed is reported accordingly by the firmware (and this is the value currently returned by ib_query_device() and ibv_query_device()). If the max number of scatter/gather entries reported by the FW is used when creating an SRQ, the creation will fail for Tavor, since the required WQE size will be increased to the next power of 2, which turns out to be larger than the device permitted max WQE size (which is not a power of 2). This patch reduces the reported SRQ max wqe size so that it can be used successfully in creating an SRQ on Tavor HCAs.

And we actually have users that report that changing it from the default set by BIOS hurts performance and/or stability for them.

Some tests conducted here in the lab do not show performance improvement from this tuning, but this might be just me.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ixgb driver is using pci_alloc_consistent, thus is should also use pci_set_consistent_dma_mask. This allows the driver to work on SGI systems. In case of an error during probing it should also disable the device again.

Also, attempt to recover if mv643xx_eth_start_xmit() is called when there are fewer free tx descriptors than expected. The BUG_ON() call we are replacing was hit on a tx_timeout that called netif_wake_queue(), indirectly via netif_device_attach(), even though we did not have enough free tx descriptors.
