Add 'frsize' member to the statfs reply.
I'm not sure if sending f_fsid will ever be needed, but just in case leave
some space at the end of the structure, so less compatibility mess would be
required.Signed-off-by: Miklos Szeredi

- Removed some kmalloc's with __GFP_ZERO and replace it with memset()
because it didn't work properly.- Fixed returned message frame in i2o_cfg_passthru() which caused raidutils
to display wrong error message in case a disk was missing.- Fixed size of printk() in i2o_scsi.c.
- Fixed get_device() and put_device() in probing of the I2O controller.

When the sclp_cpi module is loaded on a system which does not support the

Add support for multiple subchannel sets. Works with arbitrary devices in
subchannel set 1 and is transparent to device drivers. Although currently
only two subchannel sets are available, this will work with the architectured
maximum number of subchannel sets as well.Signed-off-by: Cornelia Huck

This patch introduces a struct subchannel_id containing the subchannel number
(formerly referred to as "irq") and switches code formerly relying on the
subchannel number over to it.While we're touching inline assemblies anyway, make sure they have correct
memory constraints.Signed-off-by: Cornelia Huck

New feature V=V qdio pass-through.
QDIO and HiperSockets processing in z/VM V=V guest environments (as well as
V=R with z/VM running in LPAR mode) requires shadowing of all QDIO
architecture queue elements. Especially the shadowing of SBALs and SLSBs
structures in the hypervisor, and the need to issue SIGA SYNC operations to
observe state changes, eventually causes significant CPU processing overhead
in the hypervisor.The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and
SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O.Signed-off-by: Frank Pavlic

Hugh Dickins
Fix the broken atomic_cmpxchg primitive. Add atomic_sub_and_test,
atomic64_sub_return, atomic64_sub_and_test, atomic64_cmpxchg,
atomic64_add_unless and atomic64_inc_not_zero. Replace old style
atomic_compare_and_swap by atomic_cmpxchg. Shorten the whole header by
defining most primitives with the two inline functions atomic_add_return and
atomic_sub_return.In addition this patch contains the s390 related fixes of Hugh's "mm: fill
arch atomic64 gaps" patch.Signed-off-by: Martin Schwidefsky

Free the network IRQ when closing down the network devices at shutdown.
Delete the device from the opened devices list on close.These prevent an -EBADF when later disabling SIGIO on all extant descriptors

The stack command now sends the printk output back to the mconsole client.
This is done by registering a special console for the mconsole driver. This
receives all printk output. Normally, it is ignored, but when a stack command
is issued, any printk output will be sent back to the client.This will capture any printk output, whether it is stack output or not, since
we can't tell the difference.Signed-off-by: Jeff Dike
