Subject: [patch] removes MAX_ARG_PAGES

A while back, I sent out a preliminary patch
(http://thread.gmane.org/gmane.linux.ports.hppa/752) to remove the
MAX_ARG_PAGES limit on command line sizes.  Since then, Peter Zijlstra
and I have fixed a number of bugs and addressed the various
outstanding issues.

The attached patch incorporates the following changes:

- Fixes a BUG_ON() assertion failure discovered by Ingo Molnar.
- Adds CONFIG_STACK_GROWSUP (parisc) support.
- Adds auditing support.
- Reverts to the old behavior on architectures with no MMU.
- Fixes broken execution of 64-bit binaries from 32-bit binaries.
- Adds elf_fdpic support.
- Fixes cache coherency bugs.

We've tested the following architectures: i386, x86_64, um/i386,
parisc, and frv.  These are representative of the various scenarios
which this patch addresses, but other architecture teams should try it
out to make sure there aren't any unexpected gotchas.
