The axis-mapping of lis3dev device on many (rather most) HP machines
doesn't follow the standard.  When each new model appears, users need to
adjust again.  Testing this requires the rebuild of kernel, thus it's not
trivial for end-users.

This patch adds a module parameter "axes" to allow a custom axis-mapping
without patching and recompiling the kernel driver.  User can pass the
parameter such as axes=3,2,1.  Also it can be changed via sysfs.

exofs_new_inode() was incrementing the inode->i_count and
decrementing it in create_done(), in a bad attempt to make sure
the inode will still be there when the asynchronous create_done()
finally arrives. This was very stupid because iput() was not called,
and if it was actually needed, it would leak the inode.

However all this is not needed, because at exofs_evict_inode()
we already wait for create_done() by waiting for the
object_created event. Therefore remove the superfluous ref counting
and just Thicken the comment at exofs_evict_inode() a bit.

While at it change places that open coded wait_obj_created()
to call the already available wrapper.

introduced:

CPU Topology HW:      0 0 0 4 6 4
CPU Topology SW:      0 0 0 0 4 24

The HW line describes the cpu topology nesting levels when the maximum
nesting level is used to get the corresponding SYSIB.
The SW line describes what Linux is actually using. In this case it
supports only two levels (CONFIG_SCHED_BOOK off) and therefore the
hardware folded the two lower levels in the SYSIB response block.

The dasd interrupt handler needs to distinguish solicited from
unsolicited interrupts, as unsolicited interrupts may require special
handling (e.g. summary unit checks) and solicited interrupts require
proper error recovery for the failed I/O request.
The interrupt handler needs to check several bit fields in the
interrupt response block (irb) to make this distinction.
So far our check of the status control bits has not been specific
enough, which may lead to a failed request getting just retried
instead of the necessary error recovery.

panic if a clear function is currently active at the subchannel for

the number of retries is never initialized, leading to an immediate
failure of the function which results in a kernel panic.

Fix this by initializing the iretry counter when the function is
first called. Also replace the kernel panic with a return code: a
