devm_* functions are used to replace kzalloc, request_mem_region, ioremap clk_get and request_irq functions in probe call. With the usage of devm_* functions explicit freeing and unmapping is not required. Signed-off-by:

Change the call to PTR_ERR to access the value just tested by IS_ERR.

This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED Kconfig options. Since now kernel allows many UDC drivers to be compiled, those options may turn to no longer be valid. For instance, if someone decides to build UDC that supports super speed and UDC that supports high speed only, the latter will be "assumed" to support super speed since USB_GADGET_SUPERSPEED will be selected by the former. The test of whether CONFIG_USB_GADGET_*SPEED was defined was just an optimisation which removed otherwise dead code (ie. if UDC is not dual speed, there is no need to handle cases that can happen if speed is high). This commit removes those checks. 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:

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:

Merge tag 'stable/for-linus-3.6-rc1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen Pull Xen fix from Konrad Rzeszutek Wilk: "Way back in v3.5 we added a mechanism to populate back pages that were released (they overlapped with MMIO regions), but neglected to reserve the proper amount of virtual space for extend_brk to work properly. 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.

It seems to be a timing-related issue and can be mitigated by frobbing the magic tuning parameters. We're still working on that one.

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:
