    FATAL: can't create arch/ppc/boot/lib/../../../../lib/zlib_inflate/infblock.o: No such file or directory

when building a ppc kernel using O=$(output_dir) with CONFIG_ZLIB_INFLATE=n,
because the $(output_dir)/lib/zlib_inflate directory doesn't get created.

This patch, which makes arch/ppc/boot/lib/Makefile create the
directory if needed, is one fix for the problem.

Instead, tty_io.c will always copy user space data to
kernel space, leaving the drivers to worry only about
normal kernel buffers.

No more "from_user" flag, and having the user copy in
each driver.

This cleans up the code and also fixes a number of
locking bugs.

This makes us do the proper copy_to_user() for the new
posix timers code.

I forgot to add 'const volatile' to the I/O read/write functions in the last
patch, and also forgot to update the _relaxed variants.  This patch fixes
that by adding 'const volatile' to the sn2 specific read/write routines as
well as the ia64 machine vector wrappers.

This is a big patch mostly because I trimmed shub_mmr.h down from 17M to 11k
or so.  It fixes a number of things sparse discovered and removes some dead
code, fixes up some prototypes, etc.  Of note:
 
o sn_proc_fs.c was directly dereferencing user pointers, fixed
o sn_hwperf.c was missing an include and was using asm-ia64 directly
o the I/O routines were all missing proper sparse annotations
o dead code in prominfo_proc.c has been removed
o fix generic build by putting numionodes into asm/sn/io.h

With this patch applied, the check build is pretty clean.  The sn_console bit
depends on some of the other changes, so it's included here.

Looks like we were casting a value into a union and sparse doesn't like that.

Some have noticed that the overlapping sched domains code doesn't quite work
as intended (it results in disjoint domains on some machines), and that a top
level, machine spanning domain is needed.  This patch from John Hawkes adds
it to the ia64 code.  This allows processes to run on all CPUs in large
systems, though balancing is limited.  It should go to Linus soon now
otherwise large systems will only have ~16p (depending on topology) usable by
the scheduler.  I sanity checked it on a small system after rediffing John's
original, and he's done some testing on very large systems.
 
 Nick, can you buy off on the sched.c change?  Alternatively, do you want to
 send that fix separately John? Nick did indeed ACK this change, but it isn't
 dependent on this ia64 specific part ... so it's going to be submitted
 separately.
