[S390] zcrypt: fix ap_device_list handling

2008-03-05T11:37:19+00:00

In ap_device_probe() we can add the new ap device to the internal
device list only if the device probe function successfully returns.
Otherwise we might end up with an invalid device in the internal ap
device list.

[S390] sclp_vt220: speed up console output for interactive work

2008-03-05T11:37:18+00:00

Currently an output buffer can wait up to HZ/2 until the buffer is
flushed. The wait time is noticeable in interactive tools like mc.

Change the value to HZ/20, which seems enough for interactive work.

[S390] dasd: fix reference counting in display method for proc/dasd/devices

2008-03-05T11:37:18+00:00

Using the /proc/dasd/devices interface leaves the reference counter
of alias devices in an inconsistent state. A process that tries to set
such a device offline afterwards will hang.
The dasd_devices_show function returns immediately for alias devices
and this code path was missing a dasd_put_device call.

[S390] dasd: let dasd erp matching recognize alias recovery

2008-03-05T11:37:18+00:00

When a request fails that was started on an alias device then the
first recovery step is to retry it on the base device. If the
recovery request fails again with the same symptoms, the next step
should not be a simple retry, but should be a proper recovery based
on sense data, etc. To do so, the dasd recovery functions need to
recognize the alias recovery step in the erp chain by comparing
the start devices.

Build fix for drivers/s390/char/defkeymap.c

2008-03-04T16:01:26+00:00

Commit 5ce2087ed0eb424e0889bdc9102727f65d2ecdde (Fix default compose
table initialization) left a trailing quote.

drivers/s390/char/defkeymap.c:156: error: syntax error before ';' token
make[3]: *** [drivers/s390/char/defkeymap.o] Error 1

Fix that.

Fix default compose table initialization

2008-03-03T22:53:16+00:00

Oddly enough, unsigned int c = '\300'; puts a "negative" value in c, not
0300...  This fixes the default unicode compose table by using integers
instead of character constants.

claw: make use of DIV_ROUND_UP

2008-02-24T04:57:45+00:00

The kernel.h macro DIV_ROUND_UP performs the computation
(((n) + (d) - 1) / (d)) but is perhaps more readable.

[S390] qdio: FCP/SCSI write I/O stagnates on LPAR

2008-02-19T14:29:35+00:00

If running on LPAR, qdio might overlook an incoming buffer in certain
scenarios. The patch makes sure that incoming buffers are detected
immediately in all situations.

[S390] sclp: clean up send/receive naming scheme

2008-02-19T14:29:34+00:00

Make state change events adjust the correct mask by cleaning up
naming inconsistencies. Also remove chance for lockup by removing
unnecessary mask related check before reading events.
