s390/zcrypt: ap bus rescan problem when toggle crypto adapters on/off

2013-05-02T15:10:20+00:00

The bus rescan process was called simultaneously on
every device failure. This finally leads into race
conditions (double device add/remove actions).

This patch protects the rescan area by mutual exclusion
and improves ap_config_timer handling

s390/irq: remove split irq fields from /proc/stat

2013-01-08T09:57:07+00:00

Now that irq sum accounting for /proc/stat's "intr" line works again we
have the oddity that the sum field (first field) contains only the sum
of the second (external irqs) and third field (I/O interrupts).
The reason for that is that these two fields are already sums of all other
fields. So if we would sum up everything we would count every interrupt
twice.
This is broken since the split interrupt accounting was merged two years
ago: 052ff461c8427629aee887ccc27478fc7373237c "[S390] irq: have detailed
statistics for interrupt types".
To fix this remove the split interrupt fields from /proc/stat's "intr"
line again and only have them in /proc/interrupts.

This restores the old behaviour, seems to be the only sane fix and mimics
a behaviour from other architectures where /proc/interrupts also contains
more than /proc/stat's "intr" line does.

s390/zcrypt: msgType50 (RSA-CRT) fix

2012-11-23T10:14:30+00:00

The message request handling (type50 - clear key) for RSA operations
(in CRT format) are now handled correctly with respect to the crb
format container.
