A system isn't necessarily booted on physical processor 0 as this code
assumes. Also the array happens to be allocated in .bss so it's zero
initialized anyway. Systems which need to override this can do so in
their mp_ops->smp_setup() method.

This patch changes the gpio_free implementations for the arm architecture.

If there are several snapshots sharing an origin and one is removed
while the origin is being written to, the snapshot's mempool may get
deleted while elements are still referenced.
Prior to dm-snapshot-use-per-device-mempools.patch the pending
exceptions may still have been referenced after the snapshot was
destroyed, but this was not a problem because the shared mempool
was still there.
This patch fixes the problem by tracking the number of mempool elements
in use.
The scenario:
- You have an origin and two snapshots 1 and 2.
- Someone writes to the origin.
- It creates two exceptions in the snapshots, snapshot 1 will be primary
exception, snapshot 2's pending_exception->primary_pe will point to the
exception in snapshot 1.
- The exceptions are being relocated, relocation of exception 1 finishes
(but it's pending_exception is still allocated, because it is referenced
by an exception from snapshot 2)
- The user lvremoves snapshot 1 --- it calls just suspend (does nothing)
and destructor. md->pending is zero (there is no I/O submitted to the
snapshot by md layer), so it won't help us.
- The destructor waits for kcopyd jobs to finish on snapshot 1 --- but
there are none.
- The destructor on snapshot 1 cleans up everything.
- The relocation of exception on snapshot 2 finishes, it drops reference
on primary_pe. This frees its primary_pe pointer. Primary_pe points to
pending exception created for snapshot 1. So it frees memory into
non-existing mempool.

register_snapshot() performs a GFP_KERNEL allocation while holding
_origins_lock for write, but that could write out dirty pages onto a
device that attempts to acquire _origins_lock for read, resulting in
deadlock.
So move the allocation up before taking the lock.
This path is not performance-critical, so it doesn't matter that we
allocate memory and free it if we find that we won't need it.

This patch (as1157) adds a no-name PS/2-to-USB keyboard+mouse adapter
to the hid-dell driver. (The device shows up with a Product string
saying "Generic USB K/B", nothing more.) This will force an initial
"Set-LEDs" report to be sent to the device, without which it won't
send any keystroke information. Several bug reports mentioning this
device have been filed in various forums; the patch should resolve
them.
This is just a temporary stop-gap for 2.6.28. A later patch for
2.6.29 will introduce a more generic mechanism for "Set-LEDs", making
this change (and the entire hid-dell driver) unnecessary.

In testing 2.6.28-rc1, I found that passing 'dynamic_printk' on the command
line didn't activate the debug code. The problem is that dynamic_printk_setup()
(which activates the debugging) is being called before dynamic_printk_init() is
called (which initializes infrastructure). Fix this by setting setting the
state to 'DYNAMIC_ENABLED_ALL' in dynamic_printk_setup(), which will also
cause all subsequent modules to have debugging automatically started, which is
probably the behavior we want.

This patch (as1153) fixes a potential problem in hub initialization.
Starting in 2.6.28, initialization was split into several tasks to
help speed up booting. This opens the possibility that the hub may be
autosuspended before all the initialization tasks can complete.
Normally that wouldn't matter, but with incomplete initialization
there is a risk that the hub would never autoresume -- especially if
devices were plugged into the hub beforehand. The solution is a
simple one-line change to suppress autosuspend until the
initialization is finished.

This patch (as1151) protects usbcore against drivers that try to
unlink an URB after the URB's device or bus have been removed. The
core does not currently check for this, and certain drivers can cause
a crash if they are running while an HCD is unloaded.
Certainly it would be best to fix the guilty drivers. But a little
defensive programming doesn't hurt, especially since it appears that
quite a few drivers need to be fixed.
The patch prevents the problem by grabbing a reference to the device
while an unlink is in progress and using a new spinlock to synchronize
unlinks with device removal. (There's no need to acquire a reference
to the bus as well, since the device structure itself keeps a
reference to the bus.) In addition, the kerneldoc is updated to
indicate that URBs should not be unlinked after the disconnect method
returns.

Fix headers_install.pl and headers_check.pl to be compatible with versions
of Perl less than 5.6.0. It has been tested with Perl 5.005_03 and 5.8.8.
I realize this may not be an issue for most people, but there will still
be some that hit it, I imagine. There are three basic issues:
1. Prior to 5.6.0 open() only used 2 arguments, and the versions of
the scripts in 2.6.27.1 use 3.
2. 5.6.0 also introduced the ability to use uninitialized scalar
variables as file handles, which the current scripts make use of.
3. Lastly, 5.6.0 also introduced the pragma 'use warnings'. We can use
the -w switch and be backwards compatible.

setlocalversion used to use an abbreviated git commit sha1 to generate the
tag. This was changed in commit d882421f4e08ddf0a94245cdbe516db260aa6f41
"kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish format"
to use git describe to come up with a tag. Which is nice, but git describe
sometimes can't describe the revision.
Commit 56b2f0706d82535fd8d85503f2dcc0be40c8e55d ("setlocalversion: do not
describe if there is nothing to describe") addressed this, but there is still
no tag generated.
So, generate a plain abbreviated sha1 tag like setlocalversion used to when
git describe comes up short.
