EXTRA_TARGETS has been overloaded with functionality.
This is now split in two:
targets := list targets kbuild did not know of otherwise
extra-y := list targets to be build when not building modules only.
extra-y is mainly used to list .o files that is not to be included
in the fnal built-in.o file for a directory.

EXTRA_TARGETS served several purposes before:
1) List targets to be build (built-in only)
2) Inform kbuild of targets within the makefile

Mixing the above are causing confusion, so for now on
targets :=
is used to inform kbuild about targets in a Makefile - that it otherwise
did not know about.

kbuild uses the "targets :=" information to:
a) read the dependency file .target.cmd
b) delete the target file during make clean

Introduced filechk for all architectures that previously used
update-if-changed.
No longer add asmoffsets.h.tmp to CLEAN_FILES.
This is a private file to the filechk rule

Added a new rule filechk used to check when a generated file
actually is changed. If there is no actual changes the file
is left without updating the timestamp.
When building a kernel from scratch two printouts occurs:
  CHK      file-to-generate
  UPD      file-to-generate

The first line tell that kbuild checks the file, second line tell that
the file is being updated (or created).
On successive runs only the first line is printed.
Output is the same in verbose and non-verbose mode.

This replaces the former update-if-changed which has been deleted.
generate-asm-offsets.h has been renamed as well.
All users are updated in next patch.
Output when generating compile.h follow above style

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.

Make CONFIG_SYSCTL control sys32_sysctl as well.  Based on a patch from Peter Chubb.

From Rusty Lynch:

* makes sysfs cleanup the buffer->data allocated by the attribute write
functions
* fixes a bug that causes the kernel to oops when somebody attempts to
write to the file.

This patch was previously integrated, but dropped erroneously by a bk 
merge. 

This fixes file cleanup during a sysfs directory removal by deleting files
from ->d_subdirs as they're iterated over, then checking if we can get a
reference on them.

Andy Grover told me this should be posted here.  It allows ACPI to
compile even with PCI turned off.  Patch against 2.5.60.

ia 64 part of the patch.  This gives you a 32 bit version of sys_futex (hopefully).

concurrent renames in another directory.

I doubt this can be triggered in practice, and the fix is
a bit heavy-handed, but let's see if numbers can show that
the simple fix doesn't show any real lock contention.

list.h must now include stddef since it uses NULL.

This is the "boot sector removal" patch for i386 updated for Linux
2.5.63-bk7.  The only change against the 2.5.59 version is that the
FDOPTS Makefile variable, which lets one create a floppy image with
arbitrary kernel options, has been merged from the x86-64 version, and
the comments have been updated.

The patch removes the in-kernel boot sector, which these days rarely
work correctly (it only supports up to 1 MB kernels, and only work on
legacy floppies -- not on IDE or USB devices, nor on any kind of
emulated devices like El Torito), replaces it with a placeholder stub,
and sets up the Makefile targets to create floppies or floppy images
using SYSLINUX.  The FDOPTS Makefile variable can be used to set
kernel command line options (thanks to a suggestion by Andi Kleen.)

Note that the same change has already been applied to the x86-64
architecture.  The last hunk of the patch corrects a comment in that
architecture.
