Move all register manipulation code into the core, also move register

Add check to make sure that the core is enabled and has outstanding

stay active even after the controller has been disabled until the

The clock frequecy supplied to the IP core is specific to a single

nfsd4: fix state lock usage in LOCKU
In commit 5ec094c1096ab3bb795651855d53f18daa26afde "nfsd4: extend state
lock over seqid replay logic" I modified the exit logic of all the
seqid-based procedures except nfsd4_locku(). Fix the oversight.
The result of the bug was a double-unlock while handling the LOCKU
procedure, and a warning like:

mscan: too much data copied to CAN frame due to 16 bit accesses
Due to the 16 bit access to mscan registers there's too much data copied to
the zero initialized CAN frame when having an odd number of bytes to copy.
This patch ensures that only the requested bytes are copied by using an
8 bit access for the remaining byte.

In debugging the failure of the glibc tst-cond18 test on parisc, I realized
that futexes need to use the same locks the lws calls. This fixes all the
pthread 'cond' tests. Sadly, there are still problems with thread cancellation.

The doorbell register was being unconditionally swapped. In x86, that
meant it was being swapped to BE and written to the descriptor and to
memory, depending on the case of blue frame support or writing to
doorbell register. On PPC, this meant it was being swapped to LE and
then swapped back to BE while writing to the register. But in the blue
frame case, it was being written as LE to the descriptor.
The fix is not to swap doorbell unconditionally, write it to the
register as BE and convert it to BE when writing it to the descriptor.
