There's no point in having the host name duplicated between
the mmc_host structure and the encapsulated class device
structure.

Create a mmc_host class to allow enumeration of MMC host controllers
even though they have no card(s) inserted.

Not only was this unused, but its somewhat eccentric declaration
of "static inline const unsigned long" gives gcc4 heartburn.

BCM5785 (HT1000) is a Opteron Southbridge from Serverworks/Broadcom that
incorporates a single channel ATA100 IDE controller that is functionally
identical to the Serverworks CSB6 IDE controller. This patch adds support
for the new PCI device ID and also the support for this controller.

Down the road we want to eliminate the use of the global kernel lock entirely
from the NFS client. To do this, we need to protect the fields in the
nfs_inode structure adequately. Start by serializing updates to the
"cache_validity" field.
Note this change addresses an SMP hang found by njw@osdl.org, where processes
deadlock because nfs_end_data_update and nfs_revalidate_mapping update the
"cache_validity" field without proper serialization.
Test plan:
Millions of fsx ops on SMP clients. Run Nick Wilson's breaknfs program on
large SMP clients.

Introduce atomic bitops to manipulate the bits in the nfs_inode structure's
"flags" field.
Using bitops means we can use a generic wait_on_bit call instead of an ad hoc
locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from
nfs_inode at the same time.
The other new flags field will continue to use bitmask and logic AND and OR.
This permits several flags to be set at the same time efficiently. The
following patch adds a spin lock to protect these flags, and this spin lock
will later cover other fields in the nfs_inode structure, amortizing the cost
of using this type of serialization.

Certain bits in nfsi->flags can be manipulated with atomic bitops, and some
are better manipulated via logical bitmask operations.
This patch splits the flags field into two. The next patch introduces atomic
bitops for one of the fields.

Shub2 provides a much improved mechanism for issuing internode

Update the SN address macros so that they work on both shub1
and shub2. Most of the code to support shub2 was added last year
but this patch fixes a few bugs and adds macros to help generate
both processor-specific physical addresses & numalink physical
addresses. More cleanup & optimization will be done later.
