Montecito and Montvale behaves slightly differently than previous
Itanium processors, resulting in the MCA due to a failed PIO read
to sometimes surfacing outside the nofault code.  This code is
based on discussions with Intel CPU architects and verified at
customer sites.

  [POWERPC] Fix build failure on Cell when CONFIG_SPU_FS=y

Commit aed3a8c9bb1a8623a618232087c5ff62718e3b9a introduced a
definition of notify_spus_active in .../cell/spu_syscalls.c, and
another definition under #ifndef MODULE in .../cell/spufs/sched.c.
The latter is not necessary and causes the build to fail when
CONFIG_SPU_FS=y, so this removes it.  It also removes the export
of do_notify_spus_active, which is unnecessary.

After 17d57a9206b4de6ad082ac9f2d2346985abbd2aa ("x86: fix x86-32 early
fixmap initialization.") removing lg.ko caused a printk from vunmap:

	mm/memory.c:115: bad pgd 004b3027.

On the second use after module load, the kernel crashes.

This fixes the immediate problem (accessed and dirty bits not set as
expected in pmd_none_or_clear_bad).  I can't see why this would cause
a crash, but I haven't been able to reproduce it once this is applied.

Fix a bug in the printing of the os-area magic numbers which assumed
that magic numbers were zero terminated strings.  The magic numbers
are represented in memory as integers.  If the os-area sections are
not initialized correctly they could contained random data that would
be printed to the display.  Also unify the handling of header and db
magic numbers and make both of type array of u8.

This removes an OProfile dependency on the spufs module.  This
dependency was causing a problem for multiplatform systems that are
built with support for Oprofile on Cell but try to load the oprofile
module on a non-Cell system.

This reverts commit fbdcf18df73758b2e187ab94678b30cd5f6ff9f9.

As pointed out by Yanmin Zhang, the problem was already fixed
differently (and correctly), and rather than fix anything, it actually
causes us to create a sub-optimal sched-domains hierarchy (not setting
up the domain belonging to the core) when CONFIG_X86_HT=y.
