Remove includes of <linux/smp_lock.h> where it is not used/needed.
Suggested by Al Viro.

Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc,
sparc64, and arm (all 59 defconfigs).

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

After discussions in the thread titled:
    [PATCH] scsi_debug: illegal blocking memory allocation
here is a patch containing the discussed fix and some other
fixes and additions. The patch is against lk 2.6.20-rc3 .
The version is bumped to 1.81 .

ChangeLog:
  - Change several GFP_KERNEL allocations to GFP_ATOMIC
    as they can be called from queuecommand() context
  - check above allocation returns and if out of memory
    report DID_REQUEUE in two cases, DID_NO_CONNECT in
    another, and fail slave configure() in another
  - add support for WRITE BUFFER command
  - add aborted_command error injection support
    (opts mask 0x10), similar mechanism to
    recovered_error injection.

This patch adds support for REPORT TARGET PORT GROUPS. This is used
eg for the multipathing priority callout to determine the path
priority.
With this patch multipath-tools can use the existing mpath_prio_alua
callout to exercise the path priority grouping.

See http://www.torque.net/sg/sdebug26.html for more
information on the scsi_debug driver.

ChangeLog:
  - add 'vpd_use_hostno' parameter to allow simulated hosts
    to see the same set of targets (and luns). For testing
    multipath software.
  - add 'fake_rw' parameter to ignore the data in READ and
    WRITE commands
  - add support for log subpages (new in SPC-4)
  - yield appropriate block descriptor for MODE SENSE
    commands (only for pdt=0 (i.e. disks))
  - REQUEST SENSE response no longer shows the stopped
    power condition (SAT changed to agree with SPC-3)

  - add 'virtual_gb' parameter to simulate large storage
    (by wrapping in dev_size_mb megabytes of actual ram)
  - add 'no_lun_0' parameter to skip lun 0 on each target
    (but still respond as required to INQUIRY + REPORT LUNS)
  - add well know lu support
  - add MODE SELECT commands support [pages: 0xa and 0x1c]
  - add LOG SENSE command support [pages: 0xd and 0x2f]
  - add READ CAPACITY (16) support
  - increase number of mode pages supported (to read),
    mainly transport specific (SAS) mode (sub)pages
  - add more VPD pages and extend others, including
    ATA information VPD page
  - START STOP UNIT now maintains a state machine
  - READ (16) and WRITE (16) cope with lbas larger
    than 32 bits (needed for the 'virtual_gb' parameter)
  - allow single command transfers up to 32 MB
  - more precise error (sense data) messages

This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

Wrap a highly common idiom.  Makes the code easier to read, helps pave
the way for sdev->{id,channel} removal, and adds a token that can easily
by grepped-for in the future.

There are a couple sdev_id() and scmd_printk() updates thrown in as well.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
