2008-09-29ata_piix: drop merged SCR access and use slave_link insteadTejun Heo
Now that libata has slave_link, there's no need to keep ugly merged SCR access. Drop it and use slave_link instead. This results in simpler code and much better separate link handling for master and slave. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-09-29libata: implement slave_linkTejun Heo
Explanation taken from the comment of ata_slave_link_init(). In libata, a port contains links and a link contains devices. There is single host link but if a PMP is attached to it, there can be multiple fan-out links. On SATA, there's usually a single device connected to a link but PATA and SATA controllers emulating TF based interface can have two - master and slave. However, there are a few controllers which don't fit into this abstraction too well - SATA controllers which emulate TF interface with both master and slave devices but also have separate SCR register sets for each device. These controllers need separate links for physical link handling (e.g. onlineness, link speed) but should be treated like a traditional M/S controller for everything else (e.g. command issue, softreset). slave_link is libata's way of handling this class of controllers without impacting core layer too much. For anything other than physical link handling, the default host link is used for both master and slave. For physical link handling, separate @ap->slave_link is used. All dirty details are implemented inside libata core layer. From LLD's POV, the only difference is that prereset, hardreset and postreset are called once more for the slave link, so the reset sequence looks like the following. prereset(M) -> prereset(S) -> hardreset(M) -> hardreset(S) -> softreset(M) -> postreset(M) -> postreset(S) Note that softreset is called only for the master. Softreset resets both M/S by definition, so SRST on master should handle both (the standard method will work just fine). As slave_link excludes PMP support and only code paths which deal with the attributes of physical link are affected, all the changes are localized to libata.h, libata-core.c and libata-eh.c. * ata_is_host_link() updated so that slave_link is considered as host link too. * iterator extended to iterate over the slave_link when using the underbarred version. * force param handling updated such that devno 16 is mapped to the slave link/device. * ata_link_on/offline() updated to return the combined result from master and slave link. ata_phys_link_on/offline() are the direct versions. * EH autopsy and report are performed separately for master slave links. Reset is udpated to implement the above described reset sequence. Except for reset update, most changes are minor, many of them just modifying dev->link to ata_dev_phys_link(dev) or using phys online test instead. After this update, LLDs can take full advantage of per-dev SCR registers by simply turning on slave link. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-09-29libata: reimplement link iteratorTejun Heo

2008-09-29libata: make SCR access ops per-linkTejun Heo
Logically, SCR access ops should take @link; however, there was no compelling reason to convert all SCR access ops when adding @link abstraction as there's one-to-one mapping between a port and a non-PMP link. However, that assumption won't hold anymore with the scheduled addition of slave link. Make SCR access ops per-link.

2008-09-25IPoIB: Fix crash when path record fails after path flushRoland Dreier
Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") changed how paths are flushed on an SM event. This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.

2008-09-24ath9k: disable MIB interrupts to fix interrupt stormLuis R. Rodriguez
Enabling the MIB interrupts has proven to cause an interrupt storm after 7 hours of run. We will make use of the MIB interrupt once we have ANI supported added so for now to cure this we disable the interrupt.

2008-09-23USB: revert recovery from transient errorsAlan Stern
This patch (as1135) essentially reverts the major parts of two earlier patches to usbcore, because they ended up causing a regression. Trying to recover from transient communication errors can lead to other problems, because operations that failed during the error period are not always retried. The simplest example is the initial Set-Config request sent after device enumeration; if it gets lost then it will not be retried and the device will remain unconfigured. This patch restores the old behavior in which any port disconnect or port disable causes the entire device structure to be removed, fixing a reported regression.

2008-09-23USB: fix EHCI periodic transfersDavid Brownell
As noted by Stefan Neis <Stefan.Neis@kobil.com>, we had a recent regression with EHCI periodic transfers, in some (seemingly not all that common) cases. The root cause was that the schedule activation was only loosely coupled to the addition or removal of transfers, so two different execution contexts could both think they had to deactivate (or conversely activate) the schedule. So this fix tightens that coupling, managing it more like a refcount. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-09-23USB: fix hcd interrupt disablingGeoff Levand
Commit de85422b94ddb23c021126815ea49414047c13dc, 'USB: fix interrupt disabling for HCDs with shared interrupt handlers' changed usb_add_hcd() to strip IRQF_DISABLED from irqflags prior to calling request_irq() with the justification that such a removal was necessary for shared interrupts to work properly. Unfortunately, the change in that commit unconditionally removes the IRQF_DISABLED flag, causing problems on platforms that don't use a shared interrupt but require IRQF_DISABLED. This change adds a check for IRQF_SHARED prior to removing the IRQF_DISABLED flag. Fixes the PS3 system startup hang reported with recent Fedora and OpenSUSE kernels. Note that this problem is hidden when CONFIG_LOCKDEP=y (ps3_defconfig), as local_irq_enable_in_hardirq() is defined as a null statement for that config.

2008-09-23atmel_serial: update the powersave handler to match serial coreAnti Sullin
This problem seems to be unnoticed so far: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b3b708fa2780cd2b5d8266a8f0c3a1cab364d4d2 has changed the serial core behavior to not to suspend the port if the device is enabled as a wakeup source. If the AT91 system goes to slow clock mode, the port should be suspended always and the clocks should be switched off. The patch attached updates the atmel_serial driver to match the changes in serial core. Also, the interrupts are disabled when the clock is disabled. If we disable the clock with interrupts enabled, an interrupt may get stuck. If this is the DBGU interrupt, this blocks the OR logic at system controller and thus all other sysc interrupts.

2008-09-23[Bluetooth] Fix USB disconnect handling of btusb driverMarcel Holtmann
The USB transport specification for Bluetooth splits the ACL and SCO handling into two separate interfaces. In Linux it possible to probe and disconnect these interfaces independently. So make sure that both interfaces are tightly bound together. This fixes the suspend regression that some people have expierenced.

2008-09-23[Bluetooth] Fix wrong URB handling of btusb driverMarcel Holtmann
The btusb driver contains two typos that result in some buggy behavior, but the impact is not immediately visible. During initialization the submitting of interrupt URBs might fail and then make sure to remove the correct flag and not one of the hci_dev flags. When closing down the interface make sure to kill the anchor for the ISOC URBs and not kill the interrupt URBs twice. Also cancel any scheduled work when closing down the interface.

2008-09-22ath9k: connectivity is lost after Group rekeying is doneSenthil Balasubramanian
Connectivtiy is lost after Group rekeying is done. The keytype maintained by ath9k is reset when group key is updated. Though sc_keytype can be reset only for broadcast key the proper fix would be to use mac80211 provided key type from txinfo during xmit and get rid of sc_keytype from ath9k ath_softc.

2008-09-22pcmcia: Fix broken abuse of dev->driver_dataAlan Cox
PCMCIA abuses dev->private_data in the probe methods. Unfortunately it continues to abuse it after calling drv->probe() which leads to crashes and other nasties (such as bogus probes of multifunction devices) giving errors like pcmcia: registering new device pcmcia0.1 kernel: 0.1: GetNextTuple: No more items Extract the passed data before calling the driver probe function that way we don't blow up when the driver reuses dev->private_data as its right. As its close to the final release just move the hack so it works out, hopefully someone will be sufficiently embarrassed to produce a nice rework for 2.6.28.
