qeth: Reduce CPU consumption through less SIGA-r calls

2011-11-16T22:28:20+00:00

Patch avoids SIGA-r calls in case of SIGA-r required. It only calls
SIGA-r if a threshold of free buffer is reached. CPU consumption is
reduced as a consequence.

qeth: l3 fix rcu splat in xmit

2011-11-16T22:28:14+00:00

when use dst_get_neighbour to get neighbour, we need
rcu_read_lock to protect, since dst_get_neighbour uses
rcu_dereference.

netiucv: reinsert dev_alloc_name for device naming

2011-11-16T22:28:10+00:00

Invocation of dev_alloc_name() is re-inserted, because the created
net_device name is used to create the device name for the iucv bus.
This device is created before the register_netdev call.

qeth: remove WARN_ON leftover

2011-11-16T22:28:04+00:00

The patch "qeth: exploit asynchronous delivery of storage blocks"
added a WARN_ON in qeth_schedule_recovery. A device recovery should
not cause a kernel warning. This is obviously a debugging  left-over
that we forgot to remove.

qeth: return with -EPERM if sniffing is not enabled

2011-11-16T22:27:59+00:00

Without appropriate configuration at the SE, a HiperSockets device
cannot be used for sniffing. Setting the sniffer attribute is rejected
with -EPERM.

[S390] fix mismatch in summation of I/O IRQ statistics

2011-10-30T14:16:15+00:00

Current IRQ statistics support does not show detail counts for I/O
interrupts which are processed internally only. The result is a
summation count which is way off such as this one:

           CPU0       CPU1       CPU2
I/O:       1331        710        442
[...]
QAI:         15         16         16   [I/O] QDIO Adapter Interrupt
QDI:          1          0          0   [I/O] QDIO Interrupt
DAS:        706        645        381   [I/O] DASD
C15:         26         10          0   [I/O] 3215
C70:          0          0          0   [I/O] 3270
TAP:          0          0          0   [I/O] Tape
VMR:          0          0          0   [I/O] Unit Record Devices
LCS:          0          0          0   [I/O] LCS
CLW:          0          0          0   [I/O] CLAW
CTC:          0          0          0   [I/O] CTC
APB:          0          0          0   [I/O] AP Bus

Fix this by moving I/O interrupt accounting into the common I/O layer.
