Change the WR context pool to be shared across mount points. This
reduces the RDMA transport memory footprint significantly since
idle mounts don't consume WR context memory.

Add a dma map count in order to verify that all DMA mapping resources
have been freed when the transport is closed.

Modify the RDMA_READ processing to use the reply and chunk list mapping data
types. Also add a special purpose 'hdr_count' field in in the context to hold
the header page count instead of overloading the SGE length field and
corrupting the DMA map length.

A bug in libsensors <= 2.10.6 is exposed
when this new hwmon I/F is enabled.
Create CONFIG_THERMAL_HWMON=n
until some time after libsensors 2.10.7 ships
so those users can run the latest kernel.
libsensors 3.x is already fixed -- those users
can use CONFIG_THERMAL_HWMON=y now.

The second argument "type" is not used in audit_filter_user(), so I think that type can be removed. If I'm wrong, please tell me.

If a timer fires after kvm_inject_pending_timer_irqs() but before
local_irq_disable() the code will enter guest mode and only inject such
timer interrupt the next time an unrelated event causes an exit.
It would be simpler if the timer->pending irq conversion could be done
with IRQ's disabled, so that the above problem cannot happen.
For now introduce a new vcpu requests bit to cancel guest entry.

cleanup:
Document token header size with a #define instead of open-coding it.
Don't needlessly increment "ptr" past the beginning of the header
which makes the values passed to functions more understandable and
eliminates the need for extra "krb5_hdr" pointer.
Clean up some intersecting white-space issues flagged by checkpatch.pl.
This leaves the checksum length hard-coded at 8 for DES. A later patch
cleans that up.

Rename nfsd_permission() specific MAY_* flags to NFSD_MAY_* to make it

Since we no longer make any distinction between shutdown signals with
nfsd, then it becomes easier to just standardize on a particular signal
to use to bring it down (SIGINT, in this case).

This patch is rather large, but I couldn't figure out a way to break it
up that would remain bisectable. It does several things:
- change svc_thread_fn typedef to better match what kthread_create expects
- change svc_pool_map_set_cpumask to be more kthread friendly. Make it
take a task arg and and get rid of the "oldmask"
- have svc_set_num_threads call kthread_create directly
- eliminate __svc_create_thread

This removes the BKL from the RPC service creation codepath. The BKL
really isn't adequate for this job since some of this info needs
protection across sleeps.
Also, add some comments to try and clarify how the locking should work
and to make it clear that the BKL isn't necessary as long as there is
adequate locking between tasks when touching the svc_serv fields.
