This step introduces the file arch/x86/Kconfig

The main part of the new Kconfig file is shared
and the remaining i386/x86_64 specific symbols
are covered by dependencies.
A x86_64 allmodconfig build did not show any differences.
The variable K64BIT can now be used to select the
value of CONFIG_64BIT.
This is for example useful for powerpc to generate

After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
make ARCH=x86.
With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
= select 64-bit
For x86 ARCH may say i386 or x86_64 and soon x86.
Rely on CONFIG_X64_32 to select between 32/64 or just
hardcode the value as appropriate.

- Change the prototype of pci_hp_register() to take the bus and
slot number (on parent bus) as parameters.
- Remove all the -get_address methods since this functionality
Detect all physical PCI slots as described by ACPI, and create
entries in /sys/bus/pci/slots/.
Not all physical slots are hotpluggable, and the acpiphp module
does not detect them. Now we know the physical PCI geography of
our system, without caring about hotplug.

I'm not very happy with hint #2. I struggled with ways to express it
and finally decided to ship it^W^W release early/release often. :)
Suggestions welcome.

Add a section on kconfig hints: how to do something in Kconfig files.
Fix a few typos/spellos.
Change the semantics of pci_create_slot() such that it does not
require a hotplug release() method when creating a slot. Now, we
can use this interface to create a pci_slot for any physical PCI
slots, not just hotpluggable ones.
Add new pci_slot_add_hotplug() interface so that various PCI

In kernel/exit.c we have this code :

But, mm_release() may dereference it's second argument ('mm'), so
This patch adds several markers around semaphore primitives.
Along with a tracing application this patch can be useful for measuring
kernel semaphore usage and contention.

Hmmm... More memory free? How did that happen? More pages cached for some
reason. The total available memory is increased by 8k.
Nice. Looks all reasonable. Thanks for the numbers.

These patches provide a kernel tracing interface called trace.
ChangeLog:
-Added a new example that demonstrates per-cpu continuous tracing
of data generated by marker probes.
-Removed inline from relay patch.
-Moved examples into /sample directory.
The motivation for trace is to:
- Provide a
This patch allows relay channels to be reset i.e. unconsumed.
Basically allows a 'rewind' function for flight-recorder tracing.

NFSD forgets to call mnt_drop_write after a successful rename. Here's a
fix. (Ah, the curse of a stackable file system developer: you have to debug
everyone else's too. :-)
One thing I wasn't sure is whether I could move the mnt_drop_write line a
little above, just after the call to vfs_rename.
