The proposed patch uses the aux-vector to pass the fd of the open misc
binary to the interpreter, instead of using argv[1] for that purpose.

Previous patch - open_nonreadable_binaries, offered the option of
binfmt_misc opening the binary on behalf of the interpreter.  In case
binfmt_misc is requested to do that it would pass the file-descriptor of
the open binary to the interpreter as its second argument (argv[1]).  This
method of passing the file descriptor was suspected to be problematic,
since it changes the command line that users expect to see when using tools
such as 'ps' and 'top'. 

The proposed patch changes the method of passing the fd of the open binary
to the translator.  Instead of passing it as an argument, binfmt_misc will
request the ELF loader to pass it as a new element in the aux-vector that
it prepares on the stack for ELF interpreter.  With this patch, argv[1]
will hold the full path to the binary regardless of whether it opened it or
not.

If a fault in the kernel leads to an unexpected protection fault whilst in
a code path which holds mmap_sem we will deadlock in do_page_fault() while
trying to classify the fault.  By carefully testing the source of the fault
we can detect and OOPS on the vast majority of these, greatly enhancing

We're now putting 24-byte structures into .init.setup via __setup.  But
x86_64's compiler is emitting a `.align 16' in there, so they end up on
32-byte boundaries and do_early_param()'s pointer arithmetic goes wrong.

Fix that up by forcing the compiler to align these structures to sizeof(long).

I'm hitting this problem because the module I want to load was
compiled with -g, so the filesize is absolutely huge.  kernel/module.c
does a vmalloc() to inhale the entire file, and then two calls to
module_alloc() (which calls vmalloc() on ia64) to load the 'init' and
'core' sections. The 'init' is small and slips into a gap early in the
vmalloc playspace, while the 'core' area is allocated after the huge
area that was allocated for the inhaled copy of the whole file.

I made a one coding change to Jean-Marc's version, adding a check to
see whether the init/core sections are close enough together for the
PCREL21B to reach (they almost always are).

I've kept the test that there are no jumps from core to init (though
the message that is printed is almost as unhelpful as the one that you
get when you statically link a module into the kernel that has calls
to the discarded .exit section :-)

This patch stalled out before on the question of whether a PLT was
overkill for a section-to-section branch, and whether it would be
better to use relaxation techniques to extend the range.  Doing that
might be more elegant in some way, but it needs a whole heap of extra
code (to count how many relaxed branches need to be added and
allocated them as needed).  This seems a lot of extra code that is
only ever going to be exercised by maniacs like me with 49MB .ko
files.

I fixed up the comments to be a little more heplful.

The packet scheduler simulates 64 bit jiffies on 32 bit platforms by running
a timer keeping a mark and and offset.  Since there is no locking and this is
racy and doesn't handle jiffie wrap real well.

We can use get_jiffies_64 on 2.6 do get what is needed.
The downside is the overhead of a function call, and a cache miss in
get_jiffies_64.

The last argument in the PSCHED_TDIFF_SAFE is no longer used;

This code in the csz scheduler, is just plain broken.  The TDIFF_SAFE 
effectively expands to:
	unsigned long delay = now - q->t_c;
	if (delay > 0) {
		delay = 0;
		goto do_reset;
	}
	if (delay >> q->delta_log)

So delay is always 0!  I assume that what was originally intended
is the to keep delay bounded to 1<<q->delta_log.

I don't think we're in K&R any more, Toto.

If you want a NULL pointer, use NULL. Don't use an integer.

Most of the users really didn't seem to know the proper type.

This fixes the issue where the Generic driver would bind to all usb-serial
devices, so the disconnect would not properly go to the real driver that
controlled the device.  This was very bad when unloading the module with
the device still connected.

Another patchlet after turning on preempt and rerunning tests.
- against dev.c is a genuine bug - i wish preempt would have
given a more sane hint. Strange on how its a non issue when preempt is
off. 
- against act_api.c is just an annoyance. I removed the kmod because it
will only make sense to list actions if policies exist for that action.

Gcc 3.4 has a new DFA scheduler for ia64. Unfortunately, it is not
well tested for Itanium 1. When I tried to use gcc 3.4 to compile
2.6 kernel configured for Merced, gcc failed in many places:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15598
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15653
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15655
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16130
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16142
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16143

Some of them have been fixed. But I am afraid many more remain. I don't
know how many Itanium 1 machines left in production use. If people want
to optimize kernel for Itanium 1, they can stick with the older gccs.
Or they should upgrade their machines. I think the gcc developer's time
should be better spent on somewhere else. I have been using this patch
for a while, kernel seems to work OK.

I strongly recommend that this patch be applied.

Without this patch, running tcpdump on an SMP machine with the
pegasus adapter locks up 9 times out of 10.  This is what happens:

CPU0				CPU1
pegasus_start_xmit
	netif_stop_queue
				pegasus_set_multicast
					netif_stop_queue
					netif_wake_queue

Which crashes if another packet is sent to pegasus_start_xmit before
the first one is finished.

If there are other drivers doing this, please fix them too.

took me a while to get my external usb drive running under linux-2.6.6,

one should send them to you, so here you go.

the funny thing is that it works fine unter linux-2.6.0-test11 on different
hardware, but then i'm out of my depth concerning what might have been
changed in the usb driver in the meantime. i don't really follow the
changes. i didn't find any real documentation about what these flags do,
only a couple of "my usb drive worked with 2.4 but doesn't work any more
with 2.6" messages on the web, and some of them pointed to unusual_devs.h. i
do not claim to know what i've done with this fix, but i'd like to see it
officially included. :-)

I noticed that fs/buffer.c::drop_buffers() contains some code that
AFAICS doesn't actually do anything other than waste cpu cycles so here
is patch to remove it...  The local variable was_uptodate is being

pointless.

efi.h declares a function type, and then uses that as an argument to
another function, and expects the compiler to magically demote the
function to a function pointer.

Even a gcc person (rth) was surprised that this was legal, and it
doesn't match any other use of a function pointer in the kernel, and
sparse doesn't like the implicit type-conversion.

So make the type sane in the first place, instead of depending on
a very weird corner case of the C language.

This fixes a bug in the ppc64 memset where the code that gets the
destination address aligned (or is supposed to) was looking at the
bottom 3 bits of the count rather than the destination address.  The
result of this was that the kernel wouldn't boot on POWER3 machines. 
The patch also removes an unnecessary duplicate instruction.
