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.

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.

PS I submitted this to Petkan years ago but he probably lost it.

For some reason, gcc-2.95.4 dies horridly on those asmlinkage
declarations.

I was unable to work out _why_ those functions have asmlinkage, as there
seem to be no instances of them - nobody calls
pwc_register_decompressor().
 What's up with that?

took me a while to get my external usb drive running under linux-2.6.6,
appears to need the appended fix. according to the header in unusual_devs.h
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
messed with but it is not being read anywhere so it seems entirely
pointless.

I assume this must be a remainder from old code which mucked around with
the page uptodateness but which has since been (re-)moved.

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.

There are currently two files besides mm/vmalloc.c that make use of that
function:

- arch/sh/kernel/cpu/sh4/sq.c

- arch/arm/kernel/module.c which has no prototype at all and cause

sizeof(struct kiocb) is dangerously large for a structure commonly
allocated on-stack. This patch converts the 24*sizeof(long) field,
->private, to a void pointer for use by file_operations entrypoints.
A ->dtor() method is added to the kiocb in order to support the release
of dynamically allocated structures referred to by ->private.

The sole in-tree users of ->private are async network read/write,
which are not, in fact, async, and so need not handle preallocated
->private as they would need to if ->ki_retry were ever used. The sole
truly async operations are direct IO pread()/pwrite() which do not
now use ->ki_retry(). All they would need to do in that case is to
check for ->private already being allocated for async kiocbs.

This rips 88B off the stack on 32-bit in the common case.

For each node there are a defined list of MAX_NR_ZONES zones.  These are
selected as a result of the __GFP_DMA and __GFP_HIGHMEM zone modifier flags
being passed to the memory allocator as part of the GFP mask.  Each node
has a set of zone lists, node_zonelists, which defines the list and order
of zones to scan for each flag combination.  When initialising these lists
we iterate over modifier combinations 0 ..  MAX_NR_ZONES.  However, this is
only correct when there are at most ZONES_SHIFT flags.  If another flag is
introduced zonelists for it would not be initialised.

This patch introduces GFP_ZONETYPES (based on GFP_ZONEMASK) as a bound for
the number of modifier combinations.

Like a few other drivers the vc driver is doing unlocked careless

This has been reported a couple of times and is consistently causing some
folks grief, so Urban, would you mind terribly if i send this patch to at
least clear current bug reports.  If there is additional stuff you want
ontop of this let me know and i can send a follow up patch.

The bug is that at times we haven't completed setting up the smb_ops so we
have a temporary 'null' ops in place until the connection is completely up.
 With this setup it's possible to hit ->readdir() whilst the null ops are
still in place, so we put the process to sleep until the connection setup
is complete and then call the real ->readdir().
