The PCI bus names included in /proc/iomem and /proc/ioports are
of the form 'PCI Bus #XX' where XX is the bus number.  This patch
changes the naming to 'PCI Bus XXXX:YY' where XXXX is the domain
number and YY is the bus number.  For example, PCI bus 14 in
domain 0 will show as 'PCI Bus 0000:14' instead of 'PCI Bus #14'.
This change makes the naming consistent with other architectures
such as ia64 where multiple PCI domain support has been around
longer.

This function was obviously never being used since early 2.5 days as any
device that it would try to remove would never really be removed from
the system due to the PCI device list being held in the driver core, not
the general list of PCI devices.

As we have not had a single report of a problem here in 4 years, I think
it's safe to remove now.

This lets us check if the device is really added to the driver core or
not, which is what we need when walking some of the bus lists.  The flag

no_pci_devices() should use the driver core list of PCI devices, not our
"separate" one.
Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

We currently keep 2 lists of PCI devices in the system, one in the
driver core, and one all on its own.  This second list is sorted at boot
time, in "BIOS" order, to try to remain compatible with older kernels
(2.2 and earlier days).  There was also a "nosort" option to turn this
sorting off, to remain compatible with even older kernel versions, but
that just ends up being what we have been doing from 2.5 days...

Unfortunately, the second list of devices is not really ever used to 
determine the probing order of PCI devices or drivers[1].  That is done
using the driver core list instead.  This change happened back in the
early 2.5 days.

Relying on BIOS ording for the binding of drivers to specific device
names is problematic for many reasons, and userspace tools like udev
exist to properly name devices in a persistant manner if that is needed,
no reliance on the BIOS is needed.

Matt Domsch and others at Dell noticed this back in 2006, and added a
boot option to sort the PCI device lists (both of them) in a
breadth-first manner to help remain compatible with the 2.4 order, if
needed for any reason.  This option is not going away, as some systems
rely on them.

This patch removes the sorting of the internal PCI device list in "BIOS"
mode, as it's not needed at all anymore, and hasn't for many years.
I've also removed the PCI flags for this from some other arches that for
some reason defined them, but never used them.

This should not change the ordering of any drivers or device probing.

[1] The old-style pci_get_device and pci_find_device() still used this
sorting order, but there are very few drivers that use these functions,
as they are deprecated for use in this manner.  If for some reason, a
driver rely on the order and uses these functions, the breadth-first
boot option will resolve any problem.

This cleans up the search.c file, now using the pci list of devices that
are created for the driver core, instead of relying on our separate list
of devices.  It's better to use the functions already created for this
kind of thing, instead of rolling our own all the time.

This work is done in anticipation of getting rid of that second list of
pci devices all together.

And it ends up saving code, always a nice benefit.

This also removes one compiler warning for when CONFIG_PCI_LEGACY is
enabled as we no longer internally use the deprecated functions anymore.

security_module_enable() can only be called during kernel init.
Signed-off-by: NJames Morris <jmorris@namei.org>

Add the security= boot parameter. This is done to avoid LSM
registration clashes in case of more than one bult-in module.

User can choose a security module to enable at boot. If no
security= boot parameter is specified, only the first LSM
asking for registration will be loaded. An invalid security
module name will be treated as if no module has been chosen.

LSM modules must check now if they are allowed to register
by calling security_module_enable(ops) first. Modify SELinux
and SMACK to do so.

Do not let SMACK register smackfs if it was not chosen on
boot. Smackfs assumes that smack hooks are registered and
the initial task security setup (swapper->security) is done.

This patch effectively reverts commit d0498d9a
aka "[NET]: Do not allocate unneeded memory for dev->priv alignment."
It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST
removal.

For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size"
was also 2048 bytes, but allocator with debugging options turned on started
giving out !32-byte aligned memory resulting in redzones overwrites.

Patch does small optimization in ->priv'less case: bumping size to next
32-byte boundary was always done to ensure ->priv will also be aligned.
But, no ->priv, no need to do that.

The kernel now panics reliably on boot if you have a SATAPI device
connected.

The problem was introduced by the libata merge trying to pull out all
the SFF code into a separate module.  Unfortunately, if you're a satapi
device you usually need to call atapi_request_sense, which has a bare
invocation of a SFF callback which is NULL on non-SFF HBAs.  Fix this by
making the call conditional.
