It's the only abuse of proc_iops left (except the totally b0rked comx
driver).  The patch is from Al, I just forward-ported it from 2.4.

Background: struct proc_dir_entry has a struct inode_operations *proc_iops
member, it's from Linux's stoneage and used internally by procfs to assign
either the link or directory inode ops.

Unfortunately some drivers started to abuse it do do bad things like create
on lookup (that's the comx thingy which relies on unexported symbols and thus
is broken for modular builds since mid-2.3) or various ->permission tricks
(all gone by now).

After this patch is gone I have another one that kills proc_iops and just
uses a normal conditional inside procfs to assign the right one directly.

Found this while converting netfilter modules to use the new
parameters.  Also fixes an out-by-one error in maximum elements you
can put in array.

The current "intarray" module params were never tested, and um, suck.
Only one person uses them, and it looks painful.

Since noone uses them, replace them with tested versions.

Add generic filesystem options parser (infrastructure) and use it to parse
mount options in several filesystems (adfs, affs, autofs, autofs4, ext2,
ext3, fat, hfs, hpfs, isofs, jfs, procfs, udf, and ufs).

It saves between 128 and 512 bytes per filesystem.

This attempts to take care of 2 of the MM todos I had on
my backlog:

1) Zap the stupid flush_cache_all() thing with more meaningful
   interfaces.

2) Resolve the ptrace user page access issues, first stage.

The "first stage" mentioned for #2 is simply creating the
user page accesor interfaces.  The next stage needs to be
mucking with get_user_pages() so that we can control when
the flush_dcache_page() occurs.  Then we:

1) For every platform where flush_dcache_page() is a non-nop
   add a call to the beginning of copy_{from,to}_user_page().
2) Make access_process_vm() set the "no dcache flush" bit in
   it's call to get_user_pages().

The idea also was that we'd consolidate the write etc. boolean
args passed to get_user_pages() into flag bits too.

But at least with the below, we can delete that reminder FIXME
comment from kernel/ptrace.c, the platforms have the necessary
tools and just need to make use of it :)

As a bonus I noticed that VMALLOC_VMADDR() did absolutely nothing.

After all of this I only have 1 real TODO left, and that's dealing
with the SMP TLB/pte invalidation stuff, very low priority until
someone starts doing more work with sparc32/SMP in 2.6.x :)

Remove duplicated #defines

From: Andries.Brouwer@cwi.nl

ext2 used a 32-bit field for dev_t, with possibly undefined storage
following; thus, no action was required to go to 32-bit dev_t, but going to
64-bit dev_t required some subtlety: 0 was written in the first word and
the 64 bits in the following two.  Al truncated my 64-bit stuff to 32 bits
but did not understand why there was this split, and wrote 0 followed by a
single word.  We should at least zero the word following to have
well-defined storage later.

The last change to isdn_common.c removed a label that is used when
ISDN_PPP is defined.  This patch puts it back.

From: Oliver Xymoron <oxymoron@waste.org>

I just noticed the ikconfig stuff made it into mainline via -mm. I
also just noticed that it's based in part on a patch I posted almost 5
years ago:

http://groups.google.com/groups?q=oliver+xymoron+config.gz&hl=en&lr=&ie=UTF-8&selm=fa.j8fsl5v.g08fjo%40ifi.uio.no&rnum=2

Sadly, after wandering aimlessly in the desert of unloved patches all
those years, all attribution got lost. This adds a copyright + license
to scripts/bin2c.c, which hasn't aged a day.

Currently com20020 and com20020_cs both call request_region on the same
block of ports leading to a conflict.  This patch resolves this by moving
request_region out of the generic driver and into the isa/pci/cs drivers.

The hugetlbfs_fill_super() doesn't free up memory allocated for sbinfo on
the way out in case of parsing error (and a few others).  This leads to
memory leak If root tries to mount a hugetlbfs with invalid mount option.
Here is a patch that fix the problem.

- ifdef out a couple of unused functions

- remove unused label

- __setup function is not used when compiled as a module.

This fixes the qla1280 driver to not try to release an unlocked spinlock
at boot time - as well as a couple of other minor mods.

I also changed the MMIO option to be dependant on X86_VISWS as it's
really a chipset problem and not something each and every driver should
be asking for. 

Getting a global CONFIG_MMIO_IS_BROKEN option would probable be a win
here.

This fixes (again...) CPU frequency calibration on some platforms with
the Cypress chip.  That is, at some point CLOCK_TICK_RATE has been
changed to represent RTC reference clock instead of PIC one.  Which
makes calibrate_cc_with_pic() produce utterly bogus results.

Here is a very small set of fixes for Linux/axp, with a new one for
"sched_clock" just introduced.

Note that all but the arch/alpha/mm/init.c are required for a clean
build, since warnings->errors is still on.

The arch/alpha/mm/init.c stuff is from Jeff for MARVEL, and MUST be there
for any machines running the latest firmware...

This fixes an oops with failed inode reads on UDF

Free the right buffer on allocation error

Originally, before this set of patches moving stuff out from kernel/ksyms.c,
set_cpus_schedule was EXPORT_SYMBOL_GPL, my mistake, bring it back.

Also follow Andrew Morton's suggestions of moving the EXPORT_SYMBOL{_GPL) even
closer to the place where the symbol exported is defined, i.e. just after the
symbol definition, this makes mistakes more difficult to happen, as when the
symbol definition is #ifdefed the EXPORT_SYMBOL{_GPL} is in the same block.

Our tools are somewhat too stupid.  They find a mistyped CONFIG_HIGMEM
(missing 'H') and assume a dependency on config/higmem.h. Fix the comment.

Vserver is a patch that implements BSD jail style virtual host semantics
inside Linux, where every process not only runs in its own namespace (it
reuses the chroot code for that, should switch to CLONE_NEWNS for 2.6),
but also its own hostname and IP address as well as its own view of
/proc.

Because of that added functionality, it needs more than what is
available in the LSM framework (which can only allow/deny permissions,
not alter return values).

The source code has been running stable for the last few years and is in
use at quite a few service providers.  The Fedora project also wants to
use vserver for their build system.  However, vserver for 2.4 just tacks
their syscalls onto the end of the syscall table and the userland tools
find those "dynamic numbers" somehow ...  EWWWW.

For 2.6 I'd like to do things right.  At the moment the vserver patch
has sys_new_s_context and sys_set_ipv4root calls, but since we'll
probably end up getting an ipv6 call too and people are planning future
functionality, I guess it would be more appropriate to multiplex these
through one sys_vserver patch, in the same way sys_ipc works.

For your reference, you can find more information about
vserver on these pages:

	http://www.13thfloor.at/VServer/
	http://www.solucorp.qc.ca/miscprj/s_context.hc

I estimate the project has about a dozen developers now.  We are
planning on making the implementation for 2.6 fairly lightweight,
reusing infrastructure from other code where possible and only doing
things through sys_vserver where there is no other way.

This small change just adds sys_vserver to the syscall table.

This picks up another place where aliases where getting lost.  And adds
a couple of checks.  I can't hang the osdl database thingy anymore.

The transfer alias list loops could probably quite nicely be changed to

	if (unlikely(!list_empty( old_queuelist )))
	    __list_splice( old_queuelist, new_queuelist.prev);

There doesn't seem to be any active maintainer for EFS: It's either
abandoned, or never required specific patches too badly (also quite
possible in this case). 

It went into the tree in 2.3.2 and from there to 2.6.0-test6 I see
nothing that would look like maintainer's update.  OTOH, it's read-only
and shouldn't be too badly broken (or hard to keep alive).

Outside of trunk (i.e.  in 2.4.16--) we have a backport of global 2.5
change (sb_bread()) and check for set_blocksize() failures (from Alan). 
This is the 2.6.x equivalent.
