A few very simple changes in order to make CONFIG_NUMA work everywhere, so
the distros can build one common binary kernel for distributions.

Share a common physnode_map structure between NUMA-Q and Summit.

This is a minor cleanup.  We currently define and declare the BKL's
kernel_flag spinlock on either SMP or PREEMPT, which means a UP+PREEMPT
machine gets it.

We only need the actual lock on SMP.

This also shows how to add files to the initramfs build, but is 
commented out.

Fix oops in getdfs when null path passed in on mount.  Fix oops when changed readsize caused readpages problem.  Add support for altering rsize so can reduce pages read across net
below default of 4

This fixes the SMP runqueue locking bug when updating the wakers
priority.  It also includes:

 - only update the priority and do a requeueing if the sleep average has
   changed. (this does not happen for pure CPU hogs or pure interactive
   tasks, so no need to requeue/recalc-prio in that case.) [All the
   necessary values are available at that point already, so gcc should
   have an easy job making this branch really cheap.]

 - do not do a full task activation in the migration-thread path - that is
   supposed to be near-atomic anyway.

 - fix up comments

I solved the SMP locking bug by moving the requeueing outside of
try_to_wake_up().  It does not matter that the priority update is not
atomically done now, since the current process wont do anything
inbetween.  (well, it could get preempted in a preemptible kernel, but
even that wont do any harm.)

The following messages are of interest only when debugging aio.
Otherwise, they are just console clutter.

- Remove broken lock accounting
- Introduce __locks_delete_block()
- Stop using kdevname()
- Fix locks_remove_posix()

 - fix a (now-) bug in kernel/softirq.c, it did a wakeup outside any
   atomic regions, which falsely identified random processes as a
   non-atomic wakeup, and which causes random priority boost to be
   distributed.

 - reset the initial idle thread's priority back to PRIO_MAX after doing
   the wakeup_forked_process() - correct preemption relies on this.

 - update current->prio immediately after a backboost.

 - clean up effective_prio() & sleep_avg calculations so that there are
   fewer RT-task special cases.  This has the advantage of the sleep_avg
   being maintained even for RT tasks - this could be advantegous for
   tasks that briefly enter/exit RT mode.

Seems there is a memleak on error exit path in drivers/char/vt.c, here's
the patch.  Found with help of smatch + enhanced unfree script.

__activate_task() and wake_up_forked_process() should call
nr_running_inc(rq) rather than doing a rq->nr_running++.

The console initcall patch that went in contains a typo that prevents
alpha from building.

The stack reducing patch that recently went in prevent alpha from
building (missing some ELF_CORE_COPY_XFPREGS ifdefs). The excluded
patch fixes it.

This one simply sets TARGET_CPUS to cpu_callout_map instead of
cpu_online_map so that when we finally do boot we actually use the other
cpus for servicing interrupts.

This change was wrong. pfn_to_nid is a macro.

NODE_THRESHOLD got accidentally dropped in the interactive scheduler
changes merge. This puts it back.

Apple PowerBooks want <asm/prom.h> in ohci-pci.c for the prototype of
pci_device_to_OF_node().  This patch adds it to the already present
list of PowerBook specific #includes:

This squashes (gcc-3.2) "label and end of compound statement
deprecated" warnings in usb-serial.c.

This has been around for many years but was never finished. No
need to carry it on to yet another stable kernel.

hisax.h defined a CARD_* macro for each CONFIG option, which
is totally unnecessary, just use the CONFIG option directly.
