Remove absolute path in output of drivers/scsi/script_asm.pl
Extracted from Keith Owens' kbuild-2.5 by patch@luckynet.dynu.com.

This patch was extracted from Keith Owens' kbuild-2.5 by

This patch adds the following targets, which generate some configs
useful for testing - which kind should be clear from the names:

o allyesconfig
o allmodconfig
o allnoconfig
o randconfig

It also adds

o defconfig

which does the same as make oldconfig but uses the defaults for all
new options without asking.

The actual patch was done by Ghozlane Toumi, maintained in kbuild-2.5
by Keith Owens, and extracted by Sam Ravnborg and patch@luckynet.dynu.com.

For consistency, it makes a lot of sense to add -DMODULE (plus
the other special switches with CONFIG_MODVERSIONS) to .S files
which get assembled. It surely fixes an ugly workaround for
sparc64, guess we'll see if it breaks something for other archs
(I wouldn't think so, though)

For some cases, we cannot decide if a target would change just by looking
at its prequisites, i.e. it's quite likely that it remains the same
even though a prequisite changed. The updated timestamp would cause
a lot of unnecessary recompiles. In this case, we actually generate
a temporary file, compare it to the old file and only the contents
are different do overwrite the old file.

The "update-if-changed" snippet remains always the same, so let's
put it into a macro instead of duplicating it. After that change,
scripts/mkversion_h is so small that we rather put the three remaining
lines directly into the Makefile.

into tp1.ruhr-uni-bochum.de:/home/kai/kernel/v2.5/linux-2.5.make

So here we are: make vmlinux/bzImage/whatever will now also build
modules as it goes. Other than that, everything works as usual.
"make modules" builds only the modules (but you shouldn't need
it anymore). If you don't want the modules built, you can
do "make KBUILD_MODULES= vmlinux/whatever" to only compile built-in
objects.

If people want it, I can also allow for "make vmlinux/whatever nomodules"
to do the same.

Also, add '  ' in Rules.make to properly align output in quiet mode.

If an object was changed to not export symbols anymore, the
corresponding stale .ver file would have been left lying around
and been picked up when generating modversions.h. 

The obvious solution to remove include/linux/modules/* at the
beginning of "make dep" is not really good, since that means
that .ver files would be regenerated unconditionally, thus causing
a lot of possibly unnecessary rebuilds.

So, instead, we build a temporary shadow tree of all export-objs
(as empty files) during the recursive "make fastdep" phase, and use 
that to generate modversions.h.

Ensure that we touch include/linux/modversions.h if any of the
.ver files changes, that's our marker to rebuild all modversions
affected files.

If KBUILD_VERBOSE is not set in the environment, have it default
to 1 (i.e. on)

Rules.make now has three targets:
o default (a.k.a first_rule): The actual build. Deciding whether
  to build built-in or modular or both is decided by
  $(KBUILD_MODULES) and $(KBUILD_BUILTIN) now, instead of using
  different targets
o fastdep: doesn't actually dependencies anymore, only generates
  modversions
o modules_install: Well, you guess what that does.

Cleaned up descending, and no more differentiating between 
$(subdir-y) and $(subdir-m). That means $(mod-subdirs) can
go away now.

We used to force the obvious deep structure of all objects which
export symbols into a flat list in include/linux/modules. This
initially caused the restriction the no two exporting objects could
have the same name (Ever wondered why there's ksyms.c and
i386_ksyms.c?)

With the ALSA merge this restriction was mostly lifted by some hack,
but some cases still don't work right (Hi XFS). As it's much cleaner
to just use a normal tree under include/linux/modules, reflecting the
source tree, we now do just that.

Making dependencies once up front is not ideal. For one, you don't need
them initially, since when you don't have the .o file, you bet you have
to build it no matter what the dependencies say - dependencies are about
deciding when to *re*build.

There's more reasons, like:
o you don't even know which files you'll build, so you have to go over
  all files (even over drivers/{sbus,s390,...} on i386)
o generated files don't exist yet, so you cannot pick up dependencies
  on them
o even if dependencies are right initially, they change when you work on 
  your tree or patch it, and nobody will notice unless you run "make dep"
  explicitly again

Anyway, gcc knows hows to emit a correct dependency list, so we just use
that. Well, a little bit of hacking is necessary to remove the dependency
on autoconf.h and put in individual CONFIG_WHAT_EVER dependencies instead,
since otherwise changing one config option would cause everything to be
rebuilt.

I should add that I didn't come up with this all by myself, most work
is actually done in gcc and there were discussions about using -MD on
kbuild-devel way back, so I should mention Keith Owens and Michael
Elizabeth Chastain, and probably others that I forgot, so I apologize
just in case.

We source some scripts, but still pass parameters to them, e.g.

	. mk_version_h $@ $(KERNELRELEASE) $(VERSION) ...

This does not work for all kinds of /bin/sh (it does for bash, that's
why I did not notice).

The fix is easy: Just mark the scripts executable and call instead of
source them.

Unfortunately, patch(1) doesn't understand about propagating chmod.
bk does, so changing the tree isn't hard, and we introduce an explicit
chmod a+x executed during the build for propagating this change into
those trees which get "traditionally" patched up.

Just use 'make some/dir/foo.lst' to produce mixed source code and
assembly for debugging. (If the object gets linked in and you have
a System.map, it'll relocate appropriately)

Apart from the needed Makefile bits, also clean up the script
"makelst".

Suppress echoing of commands when using "make -s", so that make -s
does indeed have the effect one would expect.

Add a quiet mode, which will print not the entire command but only
one line per rule. To turn it on, use

	make KBUILD_VERBOSE=0 vmlinux/whatever

or set KBUILD_VERBOSE=0 in your environment.

For now, the verbose mode is default, which gives you the old behavior
of printing all commands.

The output in quiet mode is based on what Keith Owens' kbuild-2.5 does,
I like, I did not want to invent yet another output format.

The current top-level Makefile has a fundamental problem which
makes "make oldconfig vmlinux" impossible:

It includes .config, which is changed by "oldconfig". So after "oldconfig"
.config has changed and the .config the Makefile had read is obsolete.
make provides a mechanism to cope with this, it'll restart automatically 
if any of the files it included changed, if you let it know that you
changed it, just using a normal rule which has .config as its target.

However, once you tell make that "make oldconfig" changes .config, you
have another problem: oldconfig always uses .config to be remade, there's
no mechanism to tell if it's up to date. So makes notices that .config
has changed, restarts, makes oldconfig again, notices that .config has
changed, restarts, ... you get the picture.

The way to solve this is to do a proper two-stage approach: If you just
say "make oldconfig", there's no need for the Makefile to even read the
.config. If it does not, it won't restart and recurse infintely.
So we divide the Makefile into two sections: One for targets which don't
need the variables from .config, like *config, clean, mrproper and
one section which does the actual build, which needs to know the
CONFIG_ options.

If one of the "noconfig" targets is given, we handle those, without
reading .config. From there, we call make again, filtering out the already
handled targets, to do the main work.

The fact that this actually works correctly can be seen by trying
"make vmlinux oldconfig" which will execute things in the right
order - and this is not just nitpicking, it means that "-j" will
get this case right, too.

The $(CONFIGURATION) hack used to start "make config" automatically
can go away now, too. Since we don't know which of make *config the
user prefers, we'll just ask him call "make whatever-config" himself,
instead of forcing "make config" on him.

The following patch cleans up the i386 usage of <linux/init.h>.
This remove <linux/init.h> from <asm-i386/system.h> which did not need
it, <asm-i386/highmem.h> which only had it due to an extern using
__init, which is not needed.

This adds <linux/init.h> to <asm-i386/bugs.h> which actually has
numerous __init functions and adds <linux/init.h> to 9 files inside of
arch/i386 which were indirectly including <linux/init.h> previously.

When trying to build mpage.c for ARM, I get errors from bio.h since kdev_t
isn't defined.  The following fixes this.

(I fail to see how this can build for anyone as it currently stands; its
probably something x86 specific buried in the asm-i386 includes.)

Another simple part of a Matthew Wilcox patch.

We do not need to pass the file descriptor to the fcntl_[sg]etlk
functions, only the struct file * which we have already got
from the file descriptor and verified.

Trivial part of a patch by Matthew Wilcox

A few cases of list_del(x) + INIT_LIST_HEAD(x) crept in recently which
can be replaced with list_del_init(x).

 - Work a bit on the automatic CRC error recovery handling. System still hangs.
   But one thing for sure - we don't have to use any specialized irq handler for
   it.

 - Since ioctl don't any longer submit requests to the queue without
   rq->special set, we can safely remove args_error handling from
   start_request.

 - Make REQ_SPECIAL usage in ide-floppy obvious.

 - Use REQ_SPECIAL everywhere instead of REQ_DRIVE_ACB. This is actually a bit
   dangerous but should work as far as I can see.

 - Unfold the now not REQ_SPECIAL specific dequeing part of ide_end_drive_cmd().
   Turns out that we can thereafter remove the calls to ide_end_drice_cmd() at
   places where the request type isn't REQ_SPECIAL all any longer. (tcq.c)


 - After the above operation it turns out that there are just two places where
   ide_end_drive_cmd remains, namely: ata_error, task_no_data_intr
   drive_cmd_intr.

   We can avoid it by changing the logics in ata_error a slightly.

   So now just to cases remain where ide_end_drive_cmd remains used:
   drive_cmd_intr and task_no_data_intr.

 - Now looking  a bit closer we can realize that drive_cmd_intr and
   task_no_data_intr can be easly merged together, since the usage of
   task_no_data_intr implied taskfile.sector_number == 0.

 - Use one single ata_special_intr function for the handling of interrupts
   submitted through ide_raw_cmd.

 - Move the remaining artefacts of ide_end_drive_cmd directly to
   ata_special_intr. Oh we don't need to check for REQ_SPECIAL any longer there,
   since the context is already known.

 - Set the ata_special_intr handler and command type directly inside
   ide_raw_taskfile to save code.

Same thing as patch #1165/1 but for 2.5.x

The kernel expects these to return values in unsigned long types.

- remove LAST_DESC in favour of passing the array size to iotable_init
- replace domain and permission bits/cache attributes with a generic
  "type", which can be easily converted to the required domain and
  permission bits/cache attributes at run time.  It also removes the
  possibility for getting such things wrong and (accidentally)
  allowing all user space to fiddle with devices directly.

This patch removes fsuser().  Now both suser() and fsuser() are gone and
all permission checks use an appropriate capable() call.

Attached patch replaces the lone remaining suser() call with capable()
and then removes suser() itself in a triumphant celebration of the glory
of capable().  Or something. ;-)

Small cleanup of capable() and some comments, too.

 - Simplify ide_cmd_type_parse by removing the handling of commands which we
   never use.

 - Realize that pre_task_out_intr and pre_task_mulout_intr are semanticaly
   identical. Use only pre_task_out_intr(). This allowed us to
   eliminate the prehandler altogether.

 - Updated fix for misconfigured host chips by Vojtech Pavlik.

 - Be more permissive about ioctl handling to allow device type drivers to do
   they own checks.

 - ali14xx cleanups by Andrej Panin.

 - Unfold usage ide_cmd_type_parser in tcq.c code. This makes this operation
   local to ide-disk.c. Move it as well as the interrupt handlers used only for
   the handling of disk requests there too.

 - Guard against calling handler before the drive is ready for it in
   ata_taskfile()! Well this bug was there before, but right now we inform
   about it.

 - Unfold ide_cmd_type_praser in ide-disk.c. Merge the remaining bits of it with
   get_command. Well it's no more.

 - Move recal_intr to ide.c - the only place where it's used.

This doesn't change the "mechanics" of the code but it makes it a lot more
"obvious" what's going on.

2.5.20 seems to be incapable of executing binaries in a ramdisk-based
root filesystem.  The ramdisk in question is an ext2fs, with a 1K
block size loaded via the compressed ramdisk loader in do_mounts().

It appears that, in the case of a 1K block sized filesystem, we attempt
to read two 512-byte sectors into a BIO vector.  The first one is copied
into the first 512 bytes.  The second sector, however, is copied over
the first 512 bytes.  Obviously not what we really want.

Rev. 2, slightly cleaned up:

Noted by Alexey Vyskubov

- Make sure proper pci id is passed to probe()
- make sure pci_dev->driver is set and reset on driver registration/unregistration
- call remove_driver to force unload of driver on unregistration

driver_unbind was called when drv->refcount == 0.
It would call driver_for_each_dev to do the unbinding
The first thing that would do was get_device, which...
BUG()'d if drv->refcount == 0. 
Duh. 

- make sure drv->devices is initialized on registration (from Peter Osterlund)
- add remove_driver for forcing removal of driver

There was a potential race with the module unload code. When a pci driver was unloaded, it would call pci_unregister_driver, which would simply call put_driver.
If the driver's refcount wasn't 0, it wouldn't unbind it from devices, but the module unload would still continue. 
If something tried to access the driver later (since everyone thinks its still there), Bad Things would happen. 
This fixes it until there can be tighter integration between the device model and module unload code.

Here's followup patch that makes it work. Notice freeze_processes() --
if you don't do that you risk data corruption.

This cleans up swsusp in 2.5.20. Killed sysrq-D support (it is too
much trouble to support suspending from interrupt), kill unused
define, fix compile-time warnings (thanks to Adam).

I created arch/i386/suspend.c not to clash with ACPI people so much in
future. (More stuff is going to move into it in the future, to clean
up functions that really do not belong to the headers.)

This patch merges in all the currently outstanding bluesmoke bits from
2.5-dj to 2.5.20, it also has the pleasant side effect of fixing the
compilation. Test compiled with and without MCE.
