2009-06-22[S390] dasd_pm: fix stop flag handlingStefan Haberland
The stop flags are handled in the generic restore function so the stop flag is removed also for FBA and DIAG devices. Signed-off-by: Stefan Haberland <stefan.haberland@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-22[S390] ap/zcrypt: Suspend/Resume ap bus and zcryptFelix Beck

2009-06-22[S390] qdio: Sanitize do_QDIO sanity checksJan Glauber

2009-06-22[S390] qdio: leave inbound SBALs primedJan Glauber
It is not required to change the state of primed SBALs. Leaving them primed saves a SQBS instruction under z/VM. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-22[S390] qdio: merge AI tasklet into interrupt handlerJan Glauber
Since the adapter interrupt tasklet only schedules the queue tasklets and contains no code that requires serialization in can be merged with the adapter interrupt handler. That possibly safes some CPU cycles. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-22[S390] qdio: extract all primed SBALs at onceJan Glauber
For devices without QIOASSIST primed SBALS were extracted in a loop. Remove the loop since get_buf_states can already return more than one primed SBAL. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-06-22[S390] qdio: fix check for running under z/VMJan Glauber
The check whether qdio runs under z/VM was incorrect since SIGA-Sync is not set if the device runs with QIOASSIST. Use MACHINE_IS_VM instead to prevent polling under z/VM. Merge qdio_inbound_q_done and tiqdio_is_inbound_q_done. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2009-06-22[S390] Use del_timer instead of del_timer_syncMichael Holzheu
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().

2009-06-21sdhci: Add support for hosts that are only capable of 1-bit transfersAnton Vorontsov
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.

2009-06-20ide-cd: prevent null pointer deref via cdrom_newpc_intrRainer Weikusat
With 2.6.30, the error handling code in cdrom_newpc_intr was changed to deal with partial request failures by normally completing the 'good' parts of a request and only 'error' the last (and presumably, incompletely transferred) bio associated with a particular request. In order to do this, ide_complete_rq is called over ide_cd_error_cmd() to partially complete the rq. The block layer does partial completion only for requests with bio's and if the rq doesn't have one (eg 'GPCMD_READ_DISC_INFO') the request is completed as a whole and the drive->hwif->rq pointer set to NULL afterwards. When calling ide_complete_rq again to report the error, this null pointer is derefenced, resulting in a kernel crash. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=13399.

2009-06-19spi_mpc83xx: add small delay after asserting chip-select lineAnton Vorontsov
This is needed for some underlaying GPIO controllers that may be a bit slow, or if chip-select signal need some time to stabilize. For what it's worth, we already have the similar delay for chip-select de-assertion case.

2009-06-19spi_mpc83xx: quieten down the "Requested speed is too low" messageAnton Vorontsov
When a platform is running at high frequencies it's not always possible to scale-down a frequency to a requested value, and using mmc_spi driver this leads to the following printk flood during card polling: ... mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use 520828 Hz instead. mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use 520828 Hz instead. ... Fix this by using WARN_ONCE(), it's better than the flood, and also better than turning dev_err() into dev_dbg(), since we actually want to warn that some things may not work correctly.

2009-06-19spi_mpc83xx: handle other Freescale processorsAnton Vorontsov
With this patch we'll able to select spi_mpc83xx driver on the MPC86xx platforms. Let the driver depend on FSL_SOC, so we don't have to worry about Kconfig anymore. Also remove the "experimental" dependency, the driver has been tested to work on a various hardware, and surely not experimental anymore.

2009-06-19gpio: driver for PrimeCell PL061 GPIO controllerBaruch Siach
This is a driver for the ARM PrimeCell PL061 GPIO AMBA peripheral. The driver is implemented using the gpiolib framework. This driver also includes support for the use of the PL061 as an interrupt controller (secondary).
