* 'for-linus' of git://git390.marist.edu/pub/scm/linux-2.6:
[S390] compile fix for latest binutils
[S390] cio: prevent purging of CCW devices in the online state
[S390] qdio: fix init sequence
[S390] Fix parameter passing for smp_switch_to_cpu()
[S390] oprofile s390: prevent stack corruption
|

The cio_ignore purge function is intended to only remove CCW devices
which are in the offline state. There is a time frame after the purge
function finished where a CCW device is scheduled for removal but
still accessible. When the device is set online during this time
frame, it may first appear online before it is then removed.
Fix this by preventing that CCW devices can be set online while there
is work (such as removal triggered by the purge function) for it
pending. Also ensure that the purge function does not schedule devices
for removal which are in the process of being set online.

The 34xx and 3590 tape driver uses the system work queue to defer work
from the interrupt function to process context, e.g. a medium sense

work queue can occur.

A data buffer that is passed to the hardware must not cross a page
boundary. zfcp uses a series of kmem_caches to align the data to not
cross a page boundary. Introduce a new kmem_cache for the FC requests
sent from the zfcp driver and use it for the ELS ADISC data. The goal
is to migrate to the FC kmem_cache in later patches and remove the
request specific kmem_caches.

zfcp requires a mempool for the status read data blocks to resubmit
the "status read" requests at any time. Each status read data block
has the size of a page (4096 bytes) and needs to be placed in one

mempool_create_page_pool to create a mempool returning pages and
remove the zfcp kmem_cache.
