Hopefully this will make it more maintainable and less error prone. Code makes use of search_exception_tables(). Since it calls this function before the kernel exeception table is sorted, there is an early call to sort_main_extable(). This way it's easy to use the already present infrastructure of fixup sections. Also this would allows to easily convert the rest of head[31|64].S into C code.

3592 tape devices are able to write data encrpyted on tape mediums. This z/Linux device driver support includes the following functions: * ioctl to switch on/off encryption * ioctl to query encryption status of drive * ioctls to set and query key encrypting keys (kekls) * long busy interrupt handling Signed-off-by: NMichael Holzheu <holzheu@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

Starting with the z9 the CPU Cryptographic Assist Facility comes with an integrated Pseudo Random Number Generator. The generator creates random numbers by an algorithm similar to the ANSI X9.17 standard. The pseudo-random numbers can be accessed via a character device driver node called /dev/prandom. Similar to /dev/urandom any amount of bytes can be read from the device without blocking.

This patch adds support for clock synchronization to an external time reference (ETR). The external time reference sends an oscillator signal and a synchronization signal every 2^20 microseconds to keep the TOD clocks of all connected servers in sync. For availability two ETR units can be connected to a machine. If the clock deviates for more than the sync-check tolerance all cpus get a machine check that indicates that the clock is out of sync. For the lovely details how to get the clock back in sync see the code below. Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

If we have a subchannel id which has been generated via for_each_subchannel(), it might contain an invalid subchannel set id. We need to catch the ensuing operand exception by using stsch_err() instead of stsch() in all possible cases.

The reserve/release IOCTLs sometimes do not work. If second system does a 'steal lock' the pending unit check (Format 3 Msg F) is delivered. Since ERP is disabled for reserve/release, the IOCTL call fails. We have to allow basic ERP (retries) for reserve/release IOCTLs.

If we try to start path verification when an unsolicited interrupt is already pending, stctl shows status pending and we delay path verification again.

The initialization of the dasd_eer code is one of the last steps of the dasd driver initialization. When initialization fails in one of the earlier steps, the dasd_exit function is called to clean up what has been done so far. So the dasd_eer_exit function may be called, although the dasd_eer_init function wasn't called before and dasd_eer_exit tries to unregister a misc device that wasn't registered, which results in a BUG. Make sure that dasd_eer_exit can be called without initialization. Use a dynamically allocated struct miscdevice instead of a static one, so we only try to unregister the device if it exists and was actually registered.

Requests are aborted when the sclp interface reports 'not operational' even though they may still be active at the sclp, leading to concurrent writes to request memory by both the kernel and the sclp interface.

MMC high-speed, wide bus support and SD high-speed are functions that aren't critical for correct operation of the card. As such, they shouldn't mark the card as bad or dead when there is a failure activating these features. This is needed in particular on some really stupid hardware (e.g. Winbond's) where not all data transfer commands are supported. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

The wbsd hardware is so incredibly brain damaged that it has an internal list of commands that result in data transfers. The result being that commands that aren't on this list aren't supported. Instead of locking up, waiting for a data interrupt that will never come, we try to fail a bit more gracefully. Signed-off-by: NPierre Ossman <drzeus@drzeus.cx>

Many controllers have an upper limit on the number of blocks that can be transferred in one request. Allow the host drivers to specify this and make sure we avoid hitting this limit. Also change the max_sectors field to avoid confusion. This makes it map less directly to the block layer limits, but as they didn't apply directly on MMC cards anyway, this isn't a great loss.

As there's only one work item (media_switcher) to handle and it's effectively serialized with itself, I found it more convenient to use kthread instead of workqueue.

Hardware does not say whether card was inserted or removed when reporting socket events. Moreover, during suspend, media can be removed or switched to some other card type without notification. Therefore, for each socket in the change set the following is performed: 1. If there's active device in the socket it's unregistered 2. Media detection is performed 3. If detection recognizes supportable media, new device is registered This patch also alters some macros and variable names to enhance clarity.
