The comment stating that xhci_setup_device() is protected by the address mutex is not true since commit 6fecd4f2 ("USB: separate usb_address0 mutexes for each bus") as xhci handles two buses. Signed-off-by:

Fix the xhci driver from bluntly setting the transferred length to 0 if we get a STALL on anything else than the data stage of a control transfer. Signed-off-by:

We used to write the root port state changes in turn for every port, sleeping 20ms after every port state change. Suspended usb2 ports need two state changes, taking minimun 40ms per port. Now instead poll the Port Link State Change (PLC) bit as the state change to U0 will set this bit. Suspended usb2 ports still need the extra 20ms delay, but we now change all the port states at once so we only need to sleep 20ms once all together Signed-off-by:

In the OTG case, the controller might not yet have been added or is removed before the system suspends. Assign xhci->main_hcd during probe to prevent NULL pointer de-reference in xhci_suspend/resume(). Use the hcd->state flag to check if HCD is halted and if that is so do nothing for xhci_suspend/resume(). [Only for xhci-plat devices, pci devices need it in gen_setup -Mathias] Signed-off-by:

The problem seems to be that if a new device is detected while we have already removed the shared HCD, then many of the xhci operations (e.g. xhci_alloc_dev(), xhci_setup_device()) hang as command never completes. I don't think XHCI can operate without the shared HCD as we've already called xhci_halt() in xhci_only_stop_hcd() when shared HCD goes away. We need to prevent new commands from being queued not only when HCD is dying but also when HCD is halted. The following lockup was detected while testing the otg state machine.

Don't set xhci->shared_hcd to NULL in xhci_stop() as we have still not de-allocated it. It was resulting in a NULL pointer de-reference if usb_add/remove_hcd() is called repeatedly. We want repeated add/remove to work for the OTG use case. Signed-off-by:

Roger Quadros authored
As xhci_hcd is now allocated by usb_create_hcd(), we don't need to add the primary HCD before creating the shared HCD. Creating the shared HCD before adding the primary HCD is particularly useful for the OTG use case so that we know at the OTG core if the HCD is in single configuration or dual (primary + shared) configuration.

Roger Quadros authored
HCD core allocates memory for HCD private data in usb_create_[shared_]hcd() so make use of that mechanism to allocate the struct xhci_hcd. Introduce struct xhci_driver_overrides to provide the size of HCD private data and hc_driver operation overrides. As of now we only need to override the reset and start methods. Signed-off-by:

Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf66 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d29 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again. Reported-and-tested-by:

Pull parisc fixes from Helge Deller: "One important patch which fixes crashes due to stack randomization on architectures where the stack grows upwards (currently parisc and metag only). This bug went unnoticed on parisc since kernel 3.14 where the flexible mmap memory layout support was added by commit 9dabf60d. The changes in fs/exec.c are inside an #ifdef CONFIG_STACK_GROWSUP section and will not affect other platforms. The other two patches rename args of the kthread_arg() function and fixes a printk output" * 'parisc-4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc,metag: Fix crashes due to stack randomization on stack-grows-upwards architectures parisc: copy_thread(): rename 'arg' argument to 'kthread_arg' parisc: %pf is only for function pointers

In commit 8ff16cf7 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation. Signed-off-by:

cpu_set was removed (along with a bunch of cpumask helpers) by commit 2f0f267e ("cpumask: remove deprecated functions."). Fix this by replacing cpu_set with cpumask_set_cpu.
