| * qeth: don't query for info if hardware not ready.Eugene Crosser2014-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When qeth device is queried for ethtool data, hardware operation is performed to extract the necessary information from the card. If the card is not online at the moment (e.g. it is undergoing recovery), this operation produces undesired effects like temporarily freezing the system. This patch prevents execution of the hardware query operation when the card is not online. In such case, ioctl() operation returns error with errno ENODEV.

* | s390/3215: fix tty output containing tabsMartin Schwidefsky2014-08-15
|/ | | | | | | | | | | | | | | | | git commit 37f81fa1f63ad38e16125526bb2769ae0ea8d332 "n_tty: do O_ONLCR translation as a single write" surfaced a bug in the 3215 device driver. In combination this broke tab expansion for tty ouput. The cause is an asymmetry in the behaviour of tty3215_ops->write vs tty3215_ops->put_char. The put_char function scans for '\t' but the write function does not. As the driver has logic for the '\t' expansion remove XTABS from c_oflag of the initial termios as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you want to use the HMC's ASCII console as console device for a z/VM guest you have to specify console=ttyS1 on the kernel command line. But it won't work until you specify conmode=sclp as well. This behavior is inconsistent with the use of the ASCII console as TTY device which works on z/VM without the need to specify a conmode. Fix this inconsistency by removing the check for conmode=sclp in the ASCII console registration function.

| * s390/cio: silence lockdep warningSebastian Ott2014-06-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems where a ccw based console device is used a lockdep false alarm could be triggered when a device driver calls printk while holding a subchannels lock (e.g. in it's irq handler). Since this is valid behavior fix this by introducing a separate lock class for the console subchannels lock. The lockdep warning was revealed by "printk: enable interrupts before calling console_trylock_for_printk()" which changed console_unlock() to be called with lockdep enabled.
