This is the core of the distributed lock manager which is required
to use GFS2 as a cluster filesystem. It is also used by CLVM and
can be used as a standalone lock manager independantly of either
of these two projects.

It implements VAX-style locking modes.

sparse can't parse a struct definition in include/asm-powerpc/lppaca.h,
even though gcc can accept it.  The form looks like this:

        struct __attribute__((whatever)) foo { };

An equivalent that both gcc and sparse can handle is

        struct foo { } __attribute__((whatever));

This is the only definition of this type in the tree, and fixing it is
easier than fixing sparse.

[ Side note: fixing sparse wouldn't be hard, but the "attribute at the
  end" version is the canonical one, and the one that makes sense. So
  let's just fix the kernel instead. Luc Van Oostenryck already sent
  out a sparse patch to the sparse mailing list in case anybody cares.

There are a couple of problems in the DMA setup code for skge.
* In the 64 bit case, it doesn't set the consistent mask.
* In the 32 bit case, the error check is backwards!
It likely will only be visible as a bug on 64 bit platforms.

Ensure a consistent value is read from the STICK register by ensuring
that both high and low are read without high changing due to a roll
over of the low register.

Various Debian/SPARC users (myself include) have noticed problems with
Hummingbird based systems. The symptoms are that the system time is
seen to jump forward 3 days, 6 hours, 11 minutes give or take a few
seconds. In many cases the system then hangs some time afterwards.

I've spotted a race condition in the code to read the STICK register.
I could not work out why 3d, 6h, 11m is important but guess that it is
due to the 2^32 jump of STICK (forwards on one read and then the next
read will seem to be backwards) during a timer interrupt. I'm guessing
that a change of -2^32 will get converted to a large unsigned
increment after the arithmetic manipulation between STICK,
nanoseconds, jiffies etc.

I did a test where I modified __hbird_read_stick to artificially
inject rollover faults forcefully every few seconds. With this I saw
the clock jump over 6 times in 12 hours compared to once every month
or so.
