Dasd code cleanup: 1) remove white space, 2) remove the emacs override sections, and 3) use kzalloc instead of kmalloc. Signed-off-by:

If a machine checks interrupts the external or the i/o interrupt handler before they have completed the cpu time calculations, the accounting goes wrong. After the cpu returned from the machine check handler to the interrupted interrupt handler, a negative cpu time delta can occur. If the accumulated cpu time in lowcore is small enough this value can get negative as well. The next jiffy interrupt will pick up that negative value, shift it by 12 and add the now huge positive value to the cpu time of the process. To solve this the machine check handler is modified not to change any of the timestamps in the lowcore if the machine check interrupted kernel context. Signed-off-by: -

The ccw dump function dasd_eckd_dump_ccw_range can crash because it does not take care about the IDAL flag in the ccw. Check for IDALs flag set in CCW and follow the indirect list to print the data that is refered by the ccw. Signed-off-by:

The initial i/o to a 3270 device is done using the static module variables raw3270_init_data and raw3270_init_request. If the 3270 device driver is built as a module and gets loaded above 2GB, the initial i/o will fail because these variables will get addresses > 2GB. To make it work the two variables are moved to struct raw3270 and the data structure is allocated with GFP_DMA. Signed-off-by: -

The software watchdog calls machine_restart from a timer function. The s390 machine_restart calls console_unblank to flush the console output. This is needed for panic to get the panic message printed. If console_unblank is called in interrupt a BUG is triggered in acquire_console_sem. That makes the software watchdog panic instead of restarting the machine. To get around this problem the call to console_unblank is made conditionally on !in_interrupt() || oops_in_progress.

Changes in the DASD driver require an asynchronous implementation of the subchannel reprobe loop. This loop was so far only used by the blacklisting mechanism but is now available to all CCW device drivers. Signed-off-by:

Work around the problem that a device cannot be unregistered from driver_for_each_device() because of klist node refcounting: Get device after device owned by the driver to be unregistered with driver_find_device() and then unregister it. This works because driver_get_device() gets us out of the region of the elevated klist node refcount. driver_find_device() will always get the next device in the list after the found one has been unregistered.

Trying to set a DASD root device online can fail under some circumstances with the message "Read configuration data returned error -5". The cause is that read configuration data incorrectly aborts with -EIO when it encounters a temporary busy condition at a storage server. Perform retry when encountering temporary busy conditions.

show_stack() passes a pointer to the current stack frame to show_trace(). Because of tail call optimization the pointer doesn't point to the original stack frame anymory and therefore traces are wrong. Don't pass the pointer of the current stack frame to show_trace(). Instead let show_trace() calculate the pointer on its own. Signed-off-by:

The recent vsnprintf() fix introduced an off-by-one, and it's now possible to overrun the target buffer by one byte. The "end" pointer points to past the end of the buffer, so if we have to truncate the result, it needs to be done though "end[-1]". [ This is just an alternate and simpler patch to one proposed by Andrew and Jeremy, who actually noticed the problem ] Acked-by:

This patch adds earlier initialization of spi_device.mode, as needed on boards using nondefault chipselect polarity. An example would be ones using the RS5C348 RTC without an external signal inverter between the RTC chipselect and the SPI controller. Without this mechanism, the first setup() call for that chip would wrongly enable chips, corrupting transfers to/from other chips sharing that SPI bus. Signed-off-by:
