People relied on the build generation number to find out if they actually
booted the right kernel, only incrementing it on config changes isn't
enough for them. So this patch goes back to the old behavior, only done
right this time:

We now don't increment the generation number on every invocation of make, 
but on every link of vmlinux. At the same time, this patch fixes the
Makefile to only relink vmlinux if any of its prequisite object files
(or the command line) changed. Incrementing the version number
happens *after* we decided to relink vmlinux.

Before overwriting version.h, check if it actually changed - otherwise
we will unnecessarily rebuild a lot of files, as e.g. module.h depends
on version.h, and many files include module.h

o Add dependencies on generated files explicitly to the
  aic7xxx Makefile - These cannot be figured out
  automatically
 
o Rename the precompiled firmware files to 
  shipped_aic7xxx_{reg,seq}.h, so that we don't overwrite 
  shipped files when regenerating the firmware

This patch restores the previous behavior of stopping the build
immediately on error (unless the -k option is given to make)

Before this patch, we would do the echo command no matter if the
compile failed, thus returning success always.

E.g. make arch/i386/kernel/process.[is] used to work at least
in the cases where the object wouldn't need any additional command
line flags defined in the local subdir.

Get back this behavior, I think I know how to do this correctly, too,
but that's for later.

Remove the default for UTS_MACHINE, it gets set in
include/linux/compile.h, just as UTS_RELEASE.

(noticed by David Gibson)

This adds a #include to drivers/pci/power.c to define __init.  At least
on PPC4xx this fixes compile problems.

The recursive build used to do the following: On entering a directory,
we would first call make in the subdirectories listed in $(subdir-y),
and then call make in the current directory again, with the target
'all_targets'.

The second invocation was used to make sure that the subdir makes completed
before trying to build the O_TARGET/L_TARGET in the current dir, since
this would link in objects in these subdirectories.

However, using correct dependencies achieves the same, i.e. just
make the objects in $(obj-y) which are not in the local subdirectory
depend on 'sub_dirs', which is the rule to descend into subdirs.

This patch actually halves the time "make vmlinux" takes when there's
nothing to do (which makes sense, as we save half of the make invocations)

There's no good reason to build the objects in init/ explicitly from
the top-level Makefile. Instead, handle init/ like every other
subdir, which also provides the automatic checks for a changed
command line etc.

Fix some trivial variable/functions/label defined (static) but not used
warnings.

Removal of locks.h broke the build due to missing definition of capable()
and current.

ips driver update ( version 5.10.13-BETA )

The lock.h header contained some hand-crafted lcoking routines from
the pre-SMP days.  In 2.5 only lock_super/unlock_super are left,
guarded by a number of completly unrelated (!) includes.

This patch moves lock_super/unlock_super to fs.h, which defined
struct super_block that is needed for those to operate it, removes
locks.h and updates all caller to not include it and add the missing,
previously nested includes where needed.

This patch implements ioctl() for getting space used by file.
I agree it's ioctl() abuse, it doesn't work on links and has
other ugly properties. Better would be to change 'struct stat'
but changing it just due to this is overkill and it will take
some time before there will be enough changes which will provoke
yet another struct stat :). So this is temporary solution...
If you don't like it, simply reject it. The function it provides
is not fundamental...

So that should be all patches. Any comments (or decision about
including/not including) welcome.

This patch implements configurable backward compatible quota interface.
Maybe this isn't needed in 2.5 but as some people want to use patches
in 2.4 where it's necessary I have implemented it.

Implemented proper syncing of dquots - ie. also global information
about quota files are synced. We find info to sync by walking through
all superblocks...

Remove use of 'short' in parameters of functions. 'int' is used instead.

Implementation of new quota format. The code is almost the same
as in -ac versions of kernel. All the code for new format is in
quota_v2.c

Implementation of old quota format. All the code for old format is now in
quota_v1.c. Code mostly remained the same as in older kernels (just minor
changes were needed to bind it with quota interface).

This is probably the largest chunk in quota patches. It removes old quotactl interface
and implements new one. New interface should not need arch specific conversions so they
are removed. All quota interface stuff is moved to quota.c so we can
easily separate things which should be compiled even if quota is disabled (mainly
because XFS needs some interface even if standard VFS quota is disabled).
Callbacks to filesystem on quota_on() and quota_off() are implemented (needed by Ext3),
quota operations callbacks are now set in super.c on superblock initialization and
not on quota_on(). This way it starts to make sense to have callbacks on alloc_space(),
alloc_inode() etc. as filesystem can override them on read_super(). This will be used
later for implementing journalled quota.

This patch implements counting of used space in inodes in bytes.
New field i_bytes is added and used space modulo 512 is kept in
it (rest is still kept in i_blocks). Functions manipulating both
i_blocks and i_bytes are implemented (inode_add_bytes(), inode_sub_bytes()
and inode_set_bytes()). Filesystems allocating only in whole blocks
can safely ignore i_bytes field and continue using i_blocks...

This patch implements accounting of used space in bytes.

  This patch moves reporting of quota statistics from Q_GETSTATS call to
/proc/fs/quota. Also reporting of registered quota formats is added.

  This patch implements list 'quota_formats' with registered quota formats
and functions register_quota_format() and unregister_quota_format() for
manipulating the list.

This patch removes most format dependent code from dquot.c and quota.h
and puts calls of callback functions instead.

  This patch adds dq_dup_ref to struct dquot. Functions altering just usage of
quota take just this duplicated reference, inodes, quotactl() helpers take real
dq_count reference. dqput() blocks if there are some duplicated references and
put reference is last 'real one'. This way is assured that quota IO is not
done from functions altering quota usage (quota structure is written on last dqput()).
