[S390] cio: introduce consistent subchannel scanning

2009-09-22T20:58:42Z

Previously, there were multiple subchannel scanning mechanisms which could potentially conflict with each other. Fix this problem by moving blacklist and ccw driver triggered scanning to the existing evaluation method. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: idset use actual number of ssids

2009-09-22T20:58:42Z

The functions idset_sch_new and for_each_subchannel_staged use different values for the number of subchannel sets. Make it consistent by changing idset_sch_new to also use the actual number of subchannel sets. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: dont kfree vmalloced memory

[S390] cio: introduce css_settle

2009-09-22T20:58:41Z

Introduce the css_driver callback settle which can be implemented by a subchannel driver to wait for the subchannel type specific asynchronous work to finish. In channel_subsystem_init_sync we call that for each subchannel driver. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: introduce css_eval_scheduled

2009-09-22T20:58:41Z

Use css_eval_scheduled to determine if all scheduled subchannel evaluation is finished. Wait for this value to be 0 in the channel subsystem init function. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: merge init calls

2009-09-22T20:58:41Z

Define initialization sequence of css and ccw bus init calls by merging them into a single init call. Also introduce channel_subsystem_init_sync to wait for the initialization of devices to finish. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

driver model: constify attribute groups

2009-09-15T16:50:47Z

Let attribute group vectors be declared "const". We'd like to let most attribute metadata live in read-only sections... this is a start. Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman

[S390] Get rid of cpuid.h header file.

2009-09-11T08:29:56Z

Merge cpuid.h header file into cpu.h. While at it convert from typedef to struct declaration and also convert cio code to use proper lowcore structure instead of casts. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] proper use of device register

2009-09-11T08:29:45Z

Don't use kfree directly after device registration started. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky

[S390] cio: remove subchannel init_name

2009-09-11T08:29:40Z

We used the init_name to set the console subchannels name early at the boot stage. With the patch cio: fix memleak in subchannel validation we moved the name setting to the point where we actually register the console subchannel. At this time we can do dynamic allocations and therefore use dev_set_name. Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky
