- Fix abuse of buffer space in scan for Media Header.

Define callback wrapper function mtd_erase_callback() to handle 
partition offsets during the callback, rather than attempting to 
fix them up in the freed erase_info structure after the callback 
has already happened.

This patch corrects a problem with Netgear FA311
ethernet card (a cheap one). Without it, the MAC address is byte swapped
ie :
HWaddr 02:00:07:E3:E9:F5
instead of :
HWaddr 00:02:E3:07:F5:E9

(the correct MAC address vendor code for Netgear/LiteOn is 00:02:E3)

The following patch adds a couple of missing byteswaps and allows the
Atmel wireless driver to work in WEP mode on big-endian CPUs. (tested
on powerPC).

* We are not correctly reporting supported bit rates.
* Fix it.

* Change the "version" OID to what it should be.
* Fix memory leaks - mgt_get_request always returns
* allocated memory for non-int OIDS (with an exception -
* keep reading). If the caller checks the return and itself
* returns, then it must free memory.
* However, it is possible to return from mgt_get_request
* early (!priv->mib). In this case, weird things can happen
* in isl_ioctl. Quick fix, at least to force an oops, is
* to set the union value to NULL. The real fix is to
* recode all mgt_get_request calls in isl_ioctl.

* We are handing back HANDLED even though the IRQ is not for us.
  We also change device state.
  This is plainly wrong.
  AFAICT we also need to take the spin lock early.
  Tested/running on UP/SMP for about a week now.
  (Discovered on one of my lappies that had the X driver on the same IRQ)
  (Proposed on Prism54 Devel with no objections)

* It seems that Viro patched prism54 with the following patch set :

cset-viro@www.linux.org.uk[torvalds]|ChangeSet|20040727040034|54764.txt

* I do not see any indication in any mailing list of this.
  It would be nice if we could be informed of such changes :-)

* (Changes committed to our CVS)

Investigation of why the build is failing due to bogus detection of
undefined symbols: We're getting this warning:

arch/i386/kernel/irq.c
{standard input}: Assembler messages:
{standard input}:3565: Warning: setting incorrect section type for
.bss.page_aligned

Which comes from this code in the 4k stacks code:

static char softirq_stack[NR_CPUS * THREAD_SIZE]  __attribute__((__aligned__(THREAD_SIZE), __section__(".bss.page_aligned")));
static char hardirq_stack[NR_CPUS * THREAD_SIZE]  __attribute__((__aligned__(THREAD_SIZE), __section__(".bss.page_aligned")));

Removing the __section__() fixes it, as does moving to gcc 3.2 or 3.3,
but gcc 2.95 and 3.0 still exhibit the problem.  It seems the 4k stack
developers like newer compilers than I do :) 

The gcc 2.95 section declaration looks like this:
	.section        .bss.page_aligned,"aw",@progbits
while the 3.1 section looks like this:
	.section        .bss.page_aligned,"aw",@nobits

It's definitely a bug that's been fixed:
http://sources.redhat.com/ml/binutils/2002-10/msg00507.html

I've been told that I can fix it with a carefully crafted assembly file and
maybe a change to the linker script, but all that it buys us is a little
space in the uncompressed kernel image.  Plus, the warning will still be
there at compile-time.  

I say, put them back in plain old BSS.

Without this patch, mainline via-rhine cannot wake the chip if some other
driver puts it to D3. The problem has hit quite a few people already.

This is a fix for the heisenbug with via-rhine refusing to work
sometimes. Patch "[9/9] Restructure reset code" contained a change made
necessary by patch [8/9]. Mainline merged [8/9] for 2.6.8 and is still
missing the fix, while -mm got it with [9/9].

Jesper Juhl provided crucial test data when no one else was able to
reproduce the symptoms.

This allows the VFS layer to the update rather than the
low-level drivers. 

Use the proper "pointer to pos" that is passed down instead.

It's causing massive user confusion, and breaks installers by
mounting the filesystem read-only.
