linux-toradex.git/drivers, branch v2.6.35.3 Linux kernel for Apalis and Colibri modules xen: Do not suspend IPI IRQs. 2010-08-13T20:31:07+00:00 Ian Campbell ian.campbell@citrix.com 2010-07-29T10:16:35+00:00 925a7e4a56ab113a1703caf76be0311f70d53b89 commit 4877c737283813bdb4bebfa3168c1585f6e3a8ca upstream. In general the semantics of IPIs are that they are are expected to continue functioning after dpm_suspend_noirq(). Specifically I have seen a deadlock between the callfunc IPI and the stop machine used by xen's do_suspend() routine. If one CPU has already called dpm_suspend_noirq() then there is a window where it can be sent a callfunc IPI before all the other CPUs have entered stop_cpu(). If this happens then the first CPU ends up spinning in stop_cpu() waiting for the other to rendezvous in state STOPMACHINE_PREPARE while the other is spinning in csd_lock_wait().

commit 4877c737283813bdb4bebfa3168c1585f6e3a8ca upstream.

In general the semantics of IPIs are that they are are expected to
continue functioning after dpm_suspend_noirq().

Specifically I have seen a deadlock between the callfunc IPI and the
stop machine used by xen's do_suspend() routine. If one CPU has already
called dpm_suspend_noirq() then there is a window where it can be sent
a callfunc IPI before all the other CPUs have entered stop_cpu().

If this happens then the first CPU ends up spinning in stop_cpu()
waiting for the other to rendezvous in state STOPMACHINE_PREPARE while
the other is spinning in csd_lock_wait().

USB: option: add huawei k3765 k4505 devices to work properly 2010-08-13T20:31:00+00:00 Andrew Bird ajb@spheresystems.co.uk 2010-07-23T15:04:41+00:00 ee567603665c2dfbc57652dd0cd6fc877b556da1 commit 0372a754be9aa43e19fd86c9bc04796d43b55e38 upstream. This patch adds the product IDs of Huawei's K3765 and K4505 mobile broadband usb modems to option.c. It also adds a quirk to the option probe function so that binding to the device's network interface(class 0xff) is avoided. This is necessary to allow another driver to bind to that, and to avoid programs like wvdial opening a nonfunctioning tty during modem discovery.
