This fixes a build failure with gcc-3.4.1, where we use some functions
before we define them inline. 

The simple way to fix those is to simply un-inline the functions in
question. Since they are somewhat large that's what I did.

An alternative would be to rework the ordering of the file so the
functions are defined before their first use.

Moxa have released several driver updates now including support up to
2.6.8 but don't themselves feel its worth the effort of doing a cleaned
up merge for the base kernel.  So I pulled their latest driver release
(1.8) and removed all the macro gunge that makes it build on
2.2.0->2.6.8.  I then fixed it to run on 2.6.9/10 and fixed a bug in the
break handling.

It still doesn't do PCI hotplug but I don't have any PCI moxa cards to
really tackle that particular case. 

I've also merged Adriank Bunk's two 'could be static' changes into this

Fix suggested by Benjamin Herrenschmidt <benh@kernel.crashing.org>

On architectures like PPC, char is handled as "unsigned char", thus the
pcm_format_data table entries with -1 give a positive 255.  This results
in Oops with OSS-emulation on such architectures.

This patch reverts the additions of an ABI supporting thread and process
CPU clocks in the posix-timers code.  This returns us to 2.6.9's condition,
there is no support for any new clockid_t values for process CPU clocks.

This also fixes the return value for clock_nanosleep when unsupported (I
think this is used only by sgi-timer at the moment).  The POSIX-specified
code for valid clocks that don't support the sleep operation is ENOTSUP.
On most architectures the kernel doesn't define ENOTSUP and this name is
defined in userland the same as the kernel's EOPNOTSUPP.

Patch from Pierre Ossman

Fix a pretty bad bug that caused sometimes signals on x86-64
to be restarted like system calls. This corrupted the RIP and
in general caused undesirable effects.

The problem happens because orig_rax is unsigned on x86-64,
but it originally was signed when the signal code was written.
And the if (orig_rax >= 0) ended up always true.
And gcc didn't warn about this, because the warning is only in 
-Wextra. 

In 2.4 we still had a cast for it, but somehow it got dropped
in 2.5.

Credit goes to John Slice for tracking it down and Erich Boleyn
for the original fix. All blame to me. I fixed it at another
place too.

This should go in before 2.6.10. It fixes a forgotten case to provide
police backward compatibility statistics for old iproute2 versions
running on a new kernel with actions enabled. Should make distributions
happy with older iproute2 versions and all-included kernel configs
since they probably favour actions over plain policer.

  cls-police: police creation succeeded

The qdisc_tree_lock is already held if we're comming via the destroy

Don't allow user space mappings in the first page even if we are
using high vectors - this may prevent BUG() from working, as well
as allowing kernel NULL pointer derefs to be silently ignored.

Rather than working out where the vector page is mapped, always
map the vector page at the high vectors location, and conditionally
handle the coherency issues with the low vector mapping if present.

This is the third of 3 patches from David Woodhouse which fix various
problems with signal handling on ppc64.

At present, if a signal is being delivered, and the process has specified
delivery of that signal on an alternate stack but the alternate stack that
has been specified is invalid (i.e.  the kernel gets a fault writing to the
alternate stack), then we (correctly) give the process a SIGSEGV but we put
the wrong signal mask in the saved state on the stack - i.e.  we put the
mask that would have been established for the original signal handler
there.

This patch fixes it by making setup_rt_frame, handle_rt_signal32 and
handle_signal32 return a status code to indicate whether they successfully
established a stack frame.  If they fail, the caller doesn't block the
signals specified for the signal handler.
