After a machine check that is handled by a debugger or by sending a
signal to a user task, set MSR.RI again.

Previously we used macros that constructed .longs since we couldn't
rely on having a recent enough binutils.  Now we check the binutils
version.

Add branch-to-self after return-from-interrupt, fix critical exception
handling, fix synchronization in set_context, other cleanups.

This also breaks the code for setting the correct priority of the NMI IRQ
out into its own function which simplifies things in a few places.

The last changes did trigger another latent bug in the inline assembly.
akpm noticed it because he compiles his kernels with frame pointers.

Uninline elv_next_request() and move it to elevator.c, where it belongs.
Because of CURRENT declaration, this actually saves lots of space.  From
Andrew.

init_rootfs() (from ramfs) doesn't appear in any header file.  I didn't
see any that looked like a good home, so lets put a prototype at the top
of fs/namespace.c.  This only use of this function is in namespace.c.

This patch makes sure the 3c509 module license is always GPL.  Currently
the MODULE_LICENSE() marco is only used when CONFIG_ISAPNP or
CONFIG_ISAPNP_MODULE is defined.  I have moved MODULE_LICENSE() to the
#ifdef MODULE section at the bottom of 3c509.c.

Same is true for the MODULE_DEVICE_TABLE() macro.

Not sure why I forgot to do this, but here is a small bit of tidying up
of some leftover parentheses from the memlist macro removal. The
parentheses are just noise and should go.

page_alloc.c does not use either slab.h or swapctl.h. This removes the
inclusion of those headers from page_alloc.c

nr_free_pages() is overly verbose. The following is perhaps clearer and
gets to the point with fewer lines of code and inside of 80 columns.

14 of our 17 architectures define sys_pause exactly the same
way.  The other three don't define it at all.  I assume glibc
translates pause() into sigsuspend() or something.

In favour of those now in kernel.h..
