Now that .init isn't implement anymore we can get rid of it and
do some more cleanup in the scsi device template:

* remove .blk - unused since 2.5.46
* remove .dev_noticed, only midlayer user is gone together with
  .init.  remaining instance now driver-private
* remove .nr_dev and .dev_max - they're purely driver internal
  and at least in sd and sr they'll be completly gone very soon.

Yes, this is the patch every maintainer of a modern HBA waited for the
last years </shameless plug>.

With all my recent changes there's no more reason to call scsi_register_host
except for the intialization it performs to every host found in
scsi_register.  But a driver can aswell do that at the end of it's
per-HBA detection routine (i.e. in ->probe for a modern PCI driver), so
export that code as scsi_add_host to drivers.  Do the same for the
release path (scsi_remove_host).  Such a new-style driver needs neither
->detect or ->release and is in theory hotplug-capable (well, once all
the races in the scsi midlayer are fixed..)

Next step of my ->init removal series.  sg does a few to much wierd
things with it's global array thay I prefer to leave it to Doug to
get rid of it (if he wants to), but this patch at least gets rid of
sg_init.

Move the register_chrdev to init_sg - open properly checks whether
the device exists so this doesn't cause any harm.  Remove the initial
allocation of the device array - the resizing code in sg_attach will
properly take care of it when called the first time.

Tested with a DVD reader/CD writer combination and ide-scsi.

Similar cleanup to the recent sd patch:  allocate the scsi_cd struct
in sd_attach instead of needing the global array and sd_init.

Tested with a DVD reader/CD write combination and ide-scsi.

Factor out code calling methods of all device template on a scsi_device
out to three helper functions in scsi.c, make scsi_devicelist static to
it and add a r/w semaphore to protect it.

Make scsi_host_list and scsi_host_hn_list static to hosts.c and remove
the never used scsi_host_tmpl_list (we only add to it and remove from
it but never traverse it)

Since osst is the last driver still implementing ->init and Willem said
he's gonna do a major update including a resync with st anyway I think
it's okay to put this hack in for now.  Instead of ->init beeing
directly called from the midlayer osst_attach now calls in in the
beginning - it has an internal protection so that the initialization
will be called only one anyway.

Both the /proc/sys/cpu/ and /proc/cpufreq interface can safely be
enabled in the same kernel. This simplifies the transition to the newer
interface. Only minor updates are needed in order to allow this to be
done.

Fix:
 - Makefile using obj-m directly, rather than subsituting the "m"
 - compiler breakage against older versions of gcc
 - adds some lacking return statements that gcc didn't catch
 - removes some 2.4 compatibility stuff
 - RTT calculation
 - puts the timeouts in terms of HZ rather than assuming HZ==100

A supplement to manfred's patch; remove copy_segments, release_segments
and even forget_segments from all architectures (except x86-64 since
Andi wants to do that seperately):

Did the changes that created this line actually build for anyone?
:-)

mbcache should be too.

This patch changes how media-change is detected to use a mechanism more
similar to what 'popular' OSes use.

The motive for this change is that more and more emulated-SCSI devices
(sbp2, usb-storage, etc) don't support START_STOP unless they need it.
Other OSes won't send a START_STOP unless the device reports NOT_READY,
indicating that it needs an explicit command to start up.

One could argue that these devices are out-of-spec, but they are so common
that they basically define the de facto spec.

Basically, any device that needs a START_STOP should still get it, but ones
that don't need it won't.

The i386 LDT code had it's own set of arch hooks (??_segments), I've
replaced most of them with the mmu context hooks in a previous patch.
The attached patch completes that change: replace release_segments with
destroy_context.

The patch is part of the -ac kernels in 2.4.  The patch breaks x86-64,
Andi Kleen promised to send you the corresponding
s/release_segments/destroy_context/ patch.

Cleaning simplified by descending down in aicasm when cleaning.

Fixed firmware build, someone made a spelling mistakei (aix -> aic).

No longer include Rules.make.

Made the *docs targets work after the restructuring of the kbuild files.

Fix cleaning up after make htmldocs, there are some directories
that needs to be deleted in that case.

This patch updates the p4-clockmod.c driver to correctly manage
HyperThreading-enabled Pentium IVs as well as those models which do
not support HyperThreading - thanks to Venkatesh Pallipadi for
explaining cpu_sibling_map to me. Additionally, an EXPORT_SYMBOL
was missing. (spotted by Marc-Christian Petersen - thanks!)

I've been posting recently. This one adds:
   - slave_attach() and slave_detach()
   - code clean up looking for a problem **
   - more debug code allowing scanning cmd sequence to
     be seen in the log (when opts=1)

** after several (never the first) sequences of modprobe/rmmod
on scsi_debug there is either:
   - an oops during modprobe when driverfs tries to create a
     directory
   - or a WARN_ON() at drivers/base/bus.c:277 during rmmod
[examples attached]

I'm not sure whether the problem is in scsi_debug, the
scsi mid level or in the driverfs code. Grepping indicates
that not many people currently utilize per driver parameters
with driverfs (i.e. driver_create_file() and
driver_remove_file()).

Update to the latest parport_gsc in the PA tree.

Some misc updates:
 - adapt our config.in changes to arch/parisc/Kconfig
 - general Makefile updaes for the new build system
 - remove asm-parisc/gsc.h in favour of asm-parisc/io.h
 - Alan-approved fix for the loff_t problem
 - Define POLLREMOVE like other architectures.
 - irq handling updates from Grant Grundler

x86 doesn't evaluate the argument to flush_dcache_page so this compilation
problem has gone overlooked:

SOM is the file format used for HPUX binaries.

This huge patch moves a bunch of drivers from arch/parisc/kernel to
drivers/parisc and adds some new drivers in drivers/parisc.

Some might argue that HPUX already has quite enough of a personality.

Build fixes, PA64 fixes, some new hpux syscalls, VFS fixes.
