Introduced ld_flags, and separated out the common parts of link_multi
for normal and module objects.
Added a bit of a comment as well

"make dir/" is used to build a subsystem without going through the
full kernel tree, neither completing the build.
This is solely useful during development, when focus is on a
single subsystem.
This is the counterpart to "make dir/module.ko"

The bugs listed was no longer relevant.
Also updated OO-INDEX

Updated documentation/modules.txt with the following:
o Default config target is menuconfig
o Documented INSTLL_MOD_PATH
o Referenced to kernel 2.4
o How to compile modules outside the kernel tree

There is a lot of stuff in need for updating, this is first step

makefiles.txt brought up-to-date with the changes that has occured
in kbuild within the last couple of months.
Restructured to present relevant info earlier, and rewritten the
architecture specific section to a certain degree.

One change in style is that makefiles used throughout the kernel tree is called
"kbuild makefiles", because they follow the kbuild syntax.
Old notation was "subdirectory makefiles".

There is added a TODO section, if anyone feel tempted to add a bit more text.

Replace done for all archs except mips* and cris.
These architectures are lacking too much behind that it made sense

In arch/$(ARCH)/Makefile the objects to be linked as the very first are specified with HEAD.
To make more consistent naming, and to allow smarter kbuild style declarations
HEAD is replaced with head-y.
Support for the old notaion is kept for now.
Only i386 updated.

The recent change in the top level makefile allowed this clean-up in all
the architecture specific Makefiles.
No functional changes, just deleted the now optional targets

archmrproper and archclean is declared .PHONY in top-level Makefile,
therefore they are no longer mandatory in arch/$(ARCH)/Makefile.

Yeah, the final step!
  
Now that we've got the checksums for the exported symbols and the
checksums of the unresolved symbols for the module we're loading,
let's compare and see.
  
Again, we allow to load a module which has the version info stripped,
but taint the kernel in that case.

We'll need that index to find the version checksum for the symbol in
a bit.

In the case of CONFIG_MODVERSIONING, the build step will only
generate preliminary <module>.o objects, and an additional
postprocessing step is necessary to record the versions of the unresolved
symbols and add them into the final <module>.ko
  
The version information for unresolved symbols is again recorded into
a special section, "__versions", which contains an array of symbol
name strings and checksum (struct modversion_info). Size is here not
an issue, since this section will not be stored permanently in kernel
memory.
  
Makefile.modver takes care of the following steps:
o Collect the version information for all exported symbols from vmlinux
  and all modules which export symbols.
o For each module, generate a C file which contains the modversion
  information for all unresolved symbols in that module.
o For each module, compile that C file to an object file
o Finally, link the <module>.ko using the preliminary <module.o> + the
  version information above.
  
The first two steps are currently done by not very efficient scripting,
so there's room for performance improvement using some helper C code.

With CONFIG_MODVERSIONING, we need to record the versions of the unresolved
symbols in the final <module>.ko, which we only know after we finished
the descending build. So we only build <module>.o in that case.
  
Also, keep track of the modules we built, the post-processing step needs
a list of all modules. Keeping track is done by touching
.tmp_versions/path/to/module.ko

For extracting the versions and finding the unresolved symbols, we
need multi-part modules to be linked together already, so this
patch separates the building of the modules as a .o file from generating
the .ko in the next step.

Store the information on the checksum alongside the rest of the 
information on exported symbols. To actually use them, we need
something to check them against first, though ;)

Also, fix some conditional debug code to actually compile.

Again, the license string is only used at load time, so no need
to store it permanently in kernel memory.

modprobe --force allows to load modules without a matching version
magic string. This invalidation is done by clearing the SHF_ALLOC
flag, so check it in the kernel. Also, clear the SHF_ALLOC flag
unconditionally, since we don't need to store the __vermagic section
in the kernel, it's only checked once at load time. 

Up to now, we had a way to store the checksums associated with the
exported symbols, but they were not filled in yet. This is done
with this patch, using the linker to actually do that for us.
  
The comment added with this patch explains what magic exactly is going
on.

This patch adds the new config option CONFIG_MODVERSIONING which will
be the new way of checking for ABI changes between kernel and module
code.

This and the following patches are in part based on an initial
implementation by Rusty Russell and I believe some of the ideas go back
to discussions on linux-kbuild, Keith Owens and Rusty.

though I'm not sure I think credit for the basic idea of
storing version info in sections goes to Keith Owens and Rusty.

o Rename __gpl_ksymtab to __ksymtab_gpl since that looks more consistent
  and appending _gpl instead of putting it into the middle simplifies
  sharing code for EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL()
o Add CONFIG_MODVERSIONING
o If CONFIG_MODVERSIONING is set, add a section __kcrctab{,_gpl}, which
  contains the ABI checksums for the exported symbols listed in 
  __ksymtab{,_crc} Since we don't know the checksums yet at compilation
  time, just make them an unresolved symbol which gets filled in by the
  linker later.

Though the CONFIG_MODVERSIONS option was removed with rusty's module
rewrite and the associated code broken, a lot of that code was still
living on here and there. Now it's gone for good.

rusty's module rewrite removed the reference to EXPORT_SYMTAB 
from linux/module.h, and it's not used anywhere else, either.

In a discussion with Sam Ravnborg, the following problem became apparent:
Most vmlinux.lds.S (but the ARM ones) used the following construct:
  
       __start___ksymtab = .;                                          
       __ksymtab         : AT(ADDR(__ksymtab) - LOAD_OFFSET) {         
               *(__ksymtab)                                            
       }                                                               
       __stop___ksymtab = .;                                           
  
However, the link will align the beginning of the section __ksymtab
according to the requirements for the input sections. If '.' (current
location counter) wasn't sufficiently aligned before, it's possible
that __ksymtab actually starts at an address after the one
__start___ksymtab points to, which will confuse the users of
__start___ksymtab badly. The fix is to follow what the ARM Makefiles
did for this case, ie
  
       __ksymtab : AT(ADDR(__ksymtab) - LOAD_OFFSET) {                 
               __start___ksymtab = .;                                  
               *(__ksymtab)                                            
               __stop___ksymtab = .;                                   
       }

__virt_to_bus/__bus_to_virt depended on INTEGRATOR_HDR0_SDRAM_BASE
Unfortunately, this is defined in arch-integrator/platform.h, and
we really don't want to include it in memory.h.

We instead use BUS_OFFSET, which will eventually depend on the CPU
number in the system.

Only default BLK_DEV_IDEDMA on BLK_DEV_IDEDMA_ICS if ARCH_ACORN is
set, not if ARM is set.  There are PCI ARM systems out there!

Ensure that we clean up properly after initialisation error,
releasing all claimed resources in an orderly manner and
returning the correct error code.

Add cfbfillrect / cfbcopyarea / cfbimgblt objects for SA1100fb.
Remove redundant "pm" member.

Found a buglet in the marvel code -- doesn't change the number of IRQS
just the logic to get there.. This applies on top of the other marvel
code.
