This patch was submitted by Olaf Hering to fix mf_proc.c where it does not
return error values correctly.

I only got iseries first time around.  Add CONFIG_DEBUG_STACKOVERFLOW for
pseries/pmac too.

Somehow we've been placing the rtas error_log file at /proc/ppc64/error_log,
which breaks at least one application I know of.  It is supposed to be at
/proc/ppc64/rtas/error_log (this is the 2.4 behavior).

This patch updates several of the ppc32 defconfigs.

From: Paul Mackerras <paulus@samba.org>

On machines with Altivec (i.e.  G4 and G5 processors), the altivec
floating-point instructions can operate in two modes: one where
denormalized inputs or outputs are truncated to zero, and one where they
aren't.  In the latter mode the processor can take an exception when it
encounters denormalized floating-point inputs or outputs rather than
dealing with them in hardware.

This patch adds code to deal properly with the exception, by emulating the
instruction that caused the exception.  Previously the kernel just switched
the altivec unit into the truncate-to-zero mode, which works but is a bit
gross.  Fortunately there are only a limited set of altivec instructions
which can generate the assist exception, so we don't have to emulate the
whole altivec instruction set.

This patch also makes sure that we always have a handler for the altivec
unavailable exception.  Without this, if you run a kernel that is not
configured for altivec support on a machine with altivec, it works fine
until a user process tries to execute an altivec instruction.  At that
point the kernel thinks it has taken an unknown exception and panics.  With
this patch it sends a SIGILL to the process instead.

This patch does nothing but fix up whitespace in three files in arch/ppc.
It deletes trailing blanks and tabs in several places and joins two lines
that didn't need to be split.

This patch adds preliminary support for the IBM PowerPC 750GX.  In summary
this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2 and more
advanced I/O pipelining.  It is beginning to appear in embedded systems and
was rumored to be under evaluation inside Apple.  Tested on PVR 70020101;
please merge.

arch/ppc64/lib/locks.c was recently added by Paulus' lock rewrite. It's
always compiled, which breaks non-SMP builds. Below patch makes it depend
on CONFIG_SMP.

This re-jigs atomic.h by providing atomic_add_return and
atomic_sub_return as other architectures do.  This allows us to
implement the atomic ops that test the new value without having
to write the underlying atomic operation in various forms.

Patch from: Ian Campbell

This changes the atomic_t in struct page named count into a private
member _count which breaks arch/arm/mm/init.c at line 80 which reads
page->count directly in show_mem().
                                                                                
The comments in the above changeset suggest that page_count(page) is
precisely equal to the old page->count semantics, even though the
semantics of _count are different, so I think the following is correct

Doesn't anyone ever actually build the patches they send me...

this makes the core use the new safe waiting helper.

  - remove wait_ms from hub driver

this is a new waiting helper safe even if we are left on a waitqueue.
This version addresses Alan's concerns about ifdefs. Please apply.

  - add delay helper that is safe even if we are still on another waitqueue

This resolves a FIXME by adding module parameters that can
be used to provide stable (vs random) addresses, and gets
rid of a runtime error from obsolete module parameter usage
in the RNDIS code.

The stable ethernet addresses are nice to hosts, which will
normally want to save them away in config databases.  For
example, without stable addresses Windows XP will end up
recording quite a lot of RNDIS devices.

This should fix the problem David Meggy found, where RNDIS was setting
the OID_GEN_CURRENT_PACKET_FILTER state incorrectly.  It's the same
issue Andrew Morton noticed a while back, for that matter, but with
more than just a "now compiles on 64 bit" fix.

Basically the code needs to interpret 32 bits provided in the request
from the (Windows) host, rather than 8 bits of other memory that's got
some irrelevant value.

The fix is just to save the 32 bits.  I did the same thing with the
CDC Ethernet filter, which should eventually be used the same way:  to
limit what packets get sent to the host.  Also defined a couple more
of the CDC requests.
