tty/hvc_opal: Fix debug function name

2012-07-10T09:16:25Z

udbg_init_debug_opal() should be udbg_init_debug_opal_raw() as the caller in arch/powerpc/kernel/udbg.c expects Signed-off-by: Benjamin Herrenschmidt

Pull five Xen bug-fixes from Konrad Rzeszutek Wilk: - When booting as PVHVM we would try to use PV console - but would not validate the parameters causing us to crash during restore b/c we re-use the wrong event channel. - When booting on machines with SR-IOV PCI bridge we didn't check for the bridge and tried to use it. - Under AMD machines would advertise the APERFMPERF resulting in needless amount of MSRs from the guest. - A global value (xen_released_pages) was not subtracted at bootup when pages were added back in. This resulted in the balloon worker having the wrong account of how many pages were truly released. - Fix dead-lock when xen-blkfront is run in the same domain as xen-blkback. * tag 'stable/for-linus-3.5-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen: mark local pages as FOREIGN in the m2p_override xen/setup: filter APERFMPERF cpuid feature out xen/balloon: Subtract from xen_released_pages the count that is populated. xen/pci: Check for PCI bridge before using it. xen/events: Add WARN_ON when quick lookup found invalid type. xen/hvc: Check HVM_PARAM_CONSOLE_[EVTCHN|PFN] for correctness. xen/hvc: Fix error cases around HVM_PARAM_CONSOLE_PFN xen/hvc: Collapse error logic.

serial: sh-sci: Make probe fail for ports that exceed the maximum count

2012-06-13T01:22:10Z

The driver supports a maximum number of ports configurable at compile time. Make sure the probe() method fails when registering a port that exceeds the maximum instead of returning success without registering the port. This fixes a crash at system suspend time, when the driver tried to suspend a non-registered port using the UART core. Signed-off-by: Laurent Pinchart Signed-off-by: Paul Mundt

serial: sh-sci: Fix probe error paths

2012-06-13T01:22:08Z

When probing fails, the driver must not try to cleanup resources that have not been initialized. Fix this. Signed-off-by: Laurent Pinchart Signed-off-by: Paul Mundt

serial/amba-pl011: move custom pin control to driver

2012-06-12T22:41:44Z

We had a boot regression in Ux500 in the merge window because two orthogonal pin control schemes for the PL011 were merged at the same time: - One using the .init() and .exit() hooks into the platform for Ux500 putting the pins into default vs sleep state respectively as the port was started/stopped. commit a09806607fd20bed2f8c41fe22793386790a14aa "ARM: ux500: switch to using pinctrl for uart0" - One hogging the default setting at PL011 probe() commit 258e055111d3cde2607e0d04eb91da2f7a59b591 "serial: amba-pl011: adopt pinctrl support" To get a solution that works for both let's scrap the stuff in the platform callbacks, instead have the driver itself select default and sleep states when the port is started/stopped. Hopefully this works for all clients. Platform callbacks are bad for device tree migration anyway, so this rids us of another problem in Ux500.

tty: Revert the tty locking series, it needs more work

2012-06-02T22:21:43Z

This reverts the tty layer change to use per-tty locking, because it's not correct yet, and fixing it will require some more deep surgery. The main revert is d29f3ef39be4 ("tty_lock: Localise the lock"), but there are several smaller commits that built upon it, they also get reverted here. The list of reverted commits is: fde86d310886 - tty: add lockdep annotations 8f6576ad476b - tty: fix ldisc lock inversion trace d3ca8b64b97e - pty: Fix lock inversion b1d679afd766 - tty: drop the pty lock during hangup abcefe5fc357 - tty/amiserial: Add missing argument for tty_unlock() fd11b42e3598 - cris: fix missing tty arg in wait_event_interruptible_tty call d29f3ef39be4 - tty_lock: Localise the lock The revert had a trivial conflict in the 68360serial.c staging driver that got removed in the meantime.
