scsi_add_lun doesn't set sdp->devfs_name before calling
scsi_register_device().  Since scsi_register_device calls down to things
like sd_probe, which do try to use sdp->devfs_name, things fail.

Just an easy change, moving the sdp->devfs_name creation before calling
scsi_register_device().

This brings the x86-64 port uptodate.  Only architecture specific
changes.

The biggest change is the forward port of the 2.4 timing code with full
HPET support.  This should improve timing stability on some Opteron
boxes considerably.

Also add the optimized low level functions from 2.4 (clear_page,
copy_page, memcpy, csum_copy etc.) They were supposed to be merged
earlier, but got dropped due to some SNAFU.  Especially the clear_page
changes should improve performance considerably, because the old version
used write combining writes which put all the new process data out of
cache.  New version serves cache hot.

Also some other bugfixes.

Full changelog:
- Re-add some lost patches: improved copy_page, clear_page, memset, memcpy,
  csum_copy from 2.4.
- New timing code from 2.4 (Bryan O'Sullivan, John Stultz, Vojtech Pavlik)
- Use correct MSR to write northbridge MCE configuration
- Fix and reenable simics check in APIC timer calibration
- Check if BIOS enabled APIC and don't use APIC mode if not.
- Remove some obsolete code in APIC handling.
- Fix potential races in the IOMMU code.
- Don't print backtrace twice on oops.
- Fix compilation of swsuspend (Pavel Machek)
- Add oops locking to kernel page faults.
- Use prefetcht0 for C level kernel prefetches.

Patch from Jakub Jelínek <jakub@redhat.com>

Make sure setfsuid/setfsgid return values are right.  Before
include/linux/security.h was added, setfsuid/setfsgid always returned
old_fsuid, no matter if the fsuid was actually changed or not.

With the default security ops it seems to do the same, because both
security_task_setuid and security_task_post_setuid return 0, but these
are hooks which seem to return 0 on success, -errno on failure, so if
some non-default security hook is installed and ever returns -errno in
setfsuid/setfsgid, -errno will be returned from the syscall instead of
the expected old_fsuid.  This makes it hard to distinguish uids
0xfffff001 ..  0xffffffff from errors of security hooks.

The task_kmod_set_label hook is no longer necessary.

kmod is now handled by keventd which already does reparent_to_init, so
there is no need to worry about getting the security labels right for
code running off the keventd workqueue.

As discussed before, this allows for early initialization of security
modules when compiled statically into the kernel.  The standard
do_initcalls is too late for complete coverage of all filesystems and
threads, for example.

As per Linus' proposal: make special macros for the user-accessible
fixmap, simplifying access checks to make it trivial to handle ia64
issues.

Once the blockdev inode for /dev/ram0 is dirtied we have a memory-backed
inode on the blockdev superblock's s_dirty list.

sync_sb_inodes() sees the memory-backed inode on the superblock and assumes
that all the other inodes on the superblock are also memory-backed.  This is
not true for the blockdev superblock!  We forget to write out dirty pages
against the following blockdevs.

Fix this by just leaving the inode dirty and moving on to inspect the other
blockdev inodes on sb->s_io.

(This is a little inefficient: an alternative is to leave dirtied
memory-backed inodes on inode_in_use, so nobody ever even considers them for
writeout.  But that introduces an inconsistency and is a bit kludgey).

Here is rocket driver patch against 2.5.70-bk18.  Changes are:

-  Removed non-GPL license text from headers
-  Removed check_region()/request_region() raciness
-  Made the driver a >2.5 driver only (as you had suggested)

already being unhashed on entry.

as we delete the entry, we can only poison the back pointer, not the
traversal pointer (rcu traversal only ever walks forward).

Make __d_drop() take this into account.
