Support more flexible child pid set/clear operations for NPTL.

there's one more improvement in the interface: set the parent-TID prior
doing the copy_mm() - this helps cfork() to pass the TID to the child as
well.

Very recent Athlons (Model 8 stepping 1 and above) (XPs/MPs and mobiles)
have an interesting problem.  Certain bits in the CLK_CTL register need
to be programmed differently to those in earlier models. The problem arises
when people plug these new CPUs into boards running BIOSes that are unaware
of this fact.

The fix is to reprogram CLK_CTL to 200xxxxx instead of 0x600xxxxx as it was
in previous models. The AMD folks have found that this improves stability.

The patch below does this reprogramming if an affected model/bios is
detected.

I'm interested if someone with an affected model could run some
benchmarks before and after to also see if this affects performance.

uClinux ports can't use mmu tricks for reading /dev/zero due to the
lack of one.  similarly it can't mmap /dev/zero.

We must always use total_swapcache_pages instead of
swapper_space.nrpages in code that doesn't depend on CONFIG_SWAP

also fix a bug in hammerfall driver, removing __exit from a function
that is called from a non __exit function.

also convert some struct initializations to C99 style and change
irq_count to tcic_irq_count, as irq_count now is a macro...

and also makes a var go to .bss...

I had to add back the smp_lock.h include to compile with CONFIG_PREEMPT,
as kernel_locked was not defined and is used by in_atomic().

Patch against the latest scsi-misc-2.5:

Fix is to only plug on prep deferral if the device queue is empty
(otherwise we can rely on returning I/O to restart the queue)

* Fix compile warning in matroxfb when only 8bpp support is enabled.
* Set memory type correctly on Matrox G400.

* Executable files on ncpfs are marked by combination of SHARED and
  SYSTEM attribute, not by SYSTEM attribute alone.

  After this change gcc output is really marked executable on ncpfs.

lcall7 and lcall27 code paths are almost identical, except one
constant. This code merges these two paths together, by moving
constant to the beginning of function.

It is possible to eliminate even more of lcall7 and lcall27
code paths, but at cost of splitting SAVE_ALL into two halves,
and I do not want to do that. But if you think that it is worth
of effort, I can save 16 more bytes, but at cost of speed.

Side effects of merge is that now stack is addressed relative
to %ebx instead of relative to %esp, so generated code is
shorter and faster.

- Use PCI_BUS_NUM_RESOURCES instead of hardcoded `4' in
  pci_find_parent_resource;
- clean up pci_claim_resource() and make it a bit more informative
  on errors;
- pdev_sort_resources() must be __devinit, as it's called from
  pbus_assign_resources_sorted(), which is __devinit now;
- fix one remaining dev->name in debugging printk.

The detection of subtractive decoding bridges is broken: `class' variable
doesn't contain ProgIf byte at this point, I should check `dev->class'
instead.

This fixes resource allocation problems on certain docking stations.

The dev_t argument of sys_mknod is passed to vfs_mknod, and is then cast
to int when foo_mknod is called, and is subsequently very often cast
back to dev_t.  (For example, minix_mknod() calls minix_set_inode() that
takes a dev_t.)

This is a cleanup that avoids this back-and-forth casting by giving
foo_mknod a prototype with dev_t.  In most cases now the dev_t is
transmitted untouched until init_special_inode.

It also makes the two routines hugetlbfs_get_inode() and
shmem_get_inode() static.

Fixes miscalculation of required module size due to alignment issues of
first section after common, and also doesn't think that no init section
is an allocation failure.

Patch from Adam Richter.  I have a nicer solution based on aliases, but
it requires coordination with USB, PCI and PCMCIA maintainers, which is
taking time.

This restores the old code in the meantime: one week without this is too
long for people who need it.

This removes Rules.make inclusions, makes make clean work properly,
removes EXTRA_TARGETS where not needed, and fixes a couple of compile
warnings in the boot wrappers where <linux/string.h> wasn't included.

This solves some mutual inclusion problems.

Now atomic.h defines the smp_mb__* macros completely itself without
needing the smp_mb definition from <asm/system.h>
