* [S390] kprobes: defer setting of ctlblk stateHeiko Carstens2009-06-22
| | | | | | | | | | | | | | | get_krobe_ctlblk returns a per cpu kprobe control block which holds the state of the current cpu wrt to kprobe. When inserting/removing a kprobe the state of the cpu which replaces the code is changed to KPROBE_SWAP_INST. This however is done when preemption is still enabled. So the state of the current cpu doesn't necessarily reflect the real state. To fix this move the code that changes the state to non-preemptible context.

* [S390] dasd: fix refcounting in dasd_change_stateSebastian Ott2009-06-22
| | | | | | | | | | | | | | | | | | To set a dasd online dasd_change_state is called twice. The first cycle will schedule initial analysis of the device, set the rc to -EAGAIN and will not touch the device state any more. The initial analysis will in turn call dasd_change_state to increase the state to the final DASD_STATE_ONLINE. If the dasd_change_state on the second thread outruns the other one both finish with the state set to DASD_STATE_ONLINE and the device refcount will be decreased by 2. Fix this by leaving dasd_change_state on rc == -EAGAIN so that the refcount will always be decreased by 1.

* [S390] Use del_timer instead of del_timer_syncMichael Holzheu2009-06-22
| | | | | | | | | | | | | When syncing the sclp console queue, we call del_timer_sync() while holding the "sclp_con_lock" spinlock. This lock is also taken in the timer function "sclp_console_timeout". Therefore the sync version of del_timer() cannot be used here. Because the synchronous deletion of the timer is only needed in the suspend callback and in that case only one CPU is remaining and therefore it is not possible that the timer function is running in parallel, we can safely use del_timer() instead of del_timer_sync().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hosts (hardware configurations, or particular SD/MMC slots) may not support 4-bit bus. For example, on MPC8569E-MDS boards we can switch between serial (1-bit only) and nibble (4-bit) modes, thought we have to disable more peripherals to work in 4-bit mode. Along with some small core changes, this patch modifies sdhci-of driver, so that now it looks for "sdhci,1-bit-only" property in the device-tree, and if specified we enable a proper quirk.
