| | | | | | | | | | Instead of the deprecated read_dev_chars() and read_conf_data_lpm(), implement dasd_generic_read_dev_chars() and dasd_eckd_read_conf_lpm(). These should even recover better from error than the original cio functions. Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

* s390: cio: Delay uevents for subchannelsCornelia Huck2007-04-271-0/+6
| | | | | | | | | | | | | | | | | We often have the situation that we register a subchannel and start device recognition, only to find out that the device is not usable after all, which triggers an unregister of the subchannel. This often happens on hundreds of subchannels on a LPAR, leading to a storm of events which aren't of any use. Therefore, use uevent_suppress to delay the KOBJ_ADD uevent for a subchannel until we know that its ccw_device is to be registered.

* qeth: Remove usage of subsys.rwsemCornelia Huck2007-04-271-2/+0
| | | | | | | | | | | | | the current driver tree contains the removal of subsys.rwsem. Unfortunately, this breaks qeth. However, it should be no problem to fix the walking of the devices for /proc/qeth: No need to take subsys.rwsem during walking the devices, driver_find_devices() should already suffice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

| | | | | | | | | | | | | | | | | | | | Now the skb->nh union has just one member, .raw, i.e. it is just like the skb->mac union, strange, no?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | s390 machines provide hardware support for creating Linux dumps on SCSI disks. For creating a dump a special purpose dump Linux is used. The first 32 MB of memory are saved by the hardware before the dump Linux is booted. Via an SCLP interface, the saved memory can be accessed from Linux. This patch exports memory and registers of the crashed Linux to userspace via a debugfs file. For more information refer to Documentation/s390/zfcpdump.txt, which is included in this patch.
