Add this to the kernel and then we can convert the tree over to use it.

This patch reorganizes the way suspend and resume notifications are
sent to drivers. The major changes are that now the PM core acquires
every device semaphore before calling the methods, and calls to
device_add() during suspends will fail, while calls to device_del()
during suspends will block.
It also provides a way to safely remove a suspended device with the
help of the PM core, by using the device_pm_schedule_removal() callback
introduced specifically for this purpose, and updates two drivers (msr
and cpuid) that need to use it.

The security_sb_post_mountroot() hook is long-since obsolete, and is
fundamentally broken: it is never invoked if someone uses initramfs.
This is particularly damaging, because the existence of this hook has
been used as motivation for not using initramfs.
Stephen Smalley confirmed on 2007-07-19 that this hook was originally
used by SELinux but can now be safely removed:

Adds security_get_sb_mnt_opts, security_set_sb_mnt_opts, and
security_clont_sb_mnt_opts to the LSM and to SELinux. This will allow
filesystems to directly own and control all of their mount options if they
so choose. This interface deals only with option identifiers and strings so
it should generic enough for any LSM which may come in the future.
Filesystems which pass text mount data around in the kernel (almost all of
them) need not currently make use of this interface when dealing with
SELinux since it will still parse those strings as it always has. I assume
future LSM's would do the same. NFS is the primary FS which does not use
text mount data and thus must make use of this interface.
An LSM would need to implement these functions only if they had mount time
options, such as selinux has context= or fscontext=. If the LSM has no
mount time options they could simply not implement and let the dummy ops
take care of things.
An LSM other than SELinux would need to define new option numbers in
security.h and any FS which decides to own there own security options would
need to be patched to use this new interface for every possible LSM. This
is because it was stated to me very clearly that LSM's should not attempt to
understand FS mount data and the burdon to understand security should be in
the FS which owns the options.

With that patch fixed.c now fully emulates MDIO bus, thus no need
to duplicate PHY layer functionality. That, in turn, drastically
simplifies the code, and drops down line count.
As an additional bonus, now there is no need to register MDIO bus
for each PHY, all emulated PHYs placed on the platform fixed MDIO bus.
There is also no more need to pre-allocate PHYs via .config option,
this is all now handled dynamically.

This patch is the beginning of moving the attribute_containers to use

Factor out ata_pci_activate_sff_host() from ata_pci_one(). This does
about the same thing as ata_host_activate() but needs to be separate
because SFF controllers use different and multiple IRQs in legacy
mode.
This will be used to make SFF LLD initialization more flexible.
