This patch (as1599) fixes dummy-hcd to make it update the appropriate driver pointer when a new gadget driver is bound or unbound. Without this change, the gadget driver's name doesn't appear in dev_printk output. Signed-off-by:

The lpc32xx_udc driver supported only one controller by defining a global static struct for it. This patch enables multiple instances of the controller by dynamic allocation of the struct at probe(). A static struct is kept as a template on initialization since it does some complex preset, reflecting fixed hardware endpoint structure. Signed-off-by:

When IORESOURCE_IRQ_SHAREABLE is set, the irq handler may be called even if the interupt of the USB module doesn't happen. So, it may clear the interrupt flags by mistake. This patch fixes it. Signed-off-by:

usb_gadget_remove_driver() runs through a four-step sequence to shut down the gadget driver. For the case of a composite gadget + at91 UDC, this would look like: udc->driver->disconnect(udc->gadget); // composite_disconnect() usb_gadget_disconnect(udc->gadget); // at91_pullup(gadget, 0) udc->driver->unbind(udc->gadget); // composite_unbind() usb_gadget_udc_stop(udc->gadget, udc->driver); // at91_stop() The UDC driver can receive SETUP packets from the host up until the point when usb_gadget_disconnect() returns. On rare occasions, the gadget driver may see this sequence: udc->driver->disconnect(udc->gadget); // composite_disconnect() udc->driver->setup(udc->gadget, &ctrl); // composite_setup() udc->driver->unbind(udc->gadget); // composite_unbind() Some gadget drivers, such as composite, assume this will never happen and crash as a result. The fix is to quiesce the UDC hardware (via usb_gadget_disconnect) before running the gadget driver through the disconnect/unbind sequence.

The timeout values were 1000 and timeout issue occured many times on my s3c6410 Soc based board (mostly when booting whith USB cable not connected). This patch increase the values to 10000 to guarantee the success of reset. Having set timeout to 10000, I printed the remained timeout values which could cause timeout issue before this change (tested several times). the first timeout value remained: timeout = 8079 timeout = 8079 timeout = 8078 timeout = 8081 the second timeout value remained: timeout = 7940 timeout = 7945 timeout = 7940 timeout = 7938 Seeing from above values, I think the value 10000 is big enough.

Fix boot up hang when enable udc without otg enabled. The root cause is that the clock will be shut down when probe routine is finished because of clock gating. When a gadget driver is registered at this time, it will call mv_udc_start which in turn will call mv_udc_vbus_session. If there is no cable attached at the boot up time, the vbus is low, so it will call stop_activity path without clock enabled which will cause system hang then. Actually, we need't go this path when clock is disabled, what we need to do is just jump out. Signed-off-by:

Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability. Signed-off-by:

Coincidentally some other commit aligned the _brk space to larger area so I didn't trigger this until it was run on a machine with more than 2GB of MMIO space." * On machines with large MMIO/PCI E820 spaces we fail to boot b/c we failed to pre-allocate large enough virtual space for extend_brk. * tag 'stable/for-linus-3.6-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/p2m: Reserve 8MB of _brk space for P2M leafs when populating back.

On a 2-node machine with 256GB of ram we get 512 lines of console output, which is just too much. This mimicks Yinghai Lu's x86 commit c2b91e2e (x86_64/mm: check and print vmemmap allocation continuous) except that we aren't ever going to get contiguous block pointers in between calls so just print when the virtual address or node changes. This decreases the output by an order of 16. Also demote this to KERN_DEBUG. Signed-off-by:

When invalidating the TLBs it is documentated as requiring a post-sync write. Failure to do so seems to result in a GPU hang. Exposure to this hang on IVB seems to be a result of removing the extra stalls required for SNB pipecontrol workarounds: commit 6c6cf5aa Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jul 20 18:02:28 2012 +0100 drm/i915: Only apply the SNB pipe control w/a to gen6 Note: Manually switch the pipe_control cmd to 4 dwords to avoid a (silent) functional conflict with -next. This way will get a loud (but conflict with next (since the scratch_addr has been deleted there).

eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.

Commit 72121572 ("GPIO: gpio-pxa: fix devicetree functions") added an "xlate" function pointer to the irq_domain_ops, but this function is nor declared or defined anywhere when CONFIG_OF is disabled, causing the build error: drivers/gpio/gpio-pxa.c:532:11: error: 'irq_domain_xlate_twocell' undeclared here (not in a function) Extending the DT-only code section to cover the irq_domain_ops and the pxa_gpio_dt_ids solves this problem and makes it clearer which code is actually used without DT.
