This is a forward port of a 2.4 driver that has been present in a couple of
(enterprise) distributions for some time.  It works for me :-), I even get
console output :-) This makes the machine almost usable - next we will get
virtual disk.

It has been considerably tidied up, but if you have any further worries
with it, let me know.

Currently the flag indicating whether or not hugepages are allowed below
4GB is not correctly propagated across fork(), which can lead to oopses.
The patch below fixes this.

From: Stephen Rothwell <sfr@canb.auug.org.au>

This patch allows iSeries to come much closer to building.

This is a precurser to my trying to merge the virtual device drivers for
iSeries (console, disk and cdrom).

From: David Gibson <david@gibson.dropbear.id.au>

The patch below fixes a bug in ppc64's 32-bit execve() path.  It duplicates
logic already in the normal fs/exec.c do_execve() to avoid dropping a NULL
mm.  The bprm.mm becomes NULL once the exec passes the "point of no
return".  Without this patch a failure past that point (e.g.  mmap()
failure) will cause an oops, with it just a killed process.

I played with it a little more, and pretty much got everything working,

This patch is needed for the USB storage subsystem to recognize the

After much discussion with the SCSI folks, here's a patch to export
max_sectors as a sysfs attribute.  Turning this down makes some people's
devices more stable, but at a significant cost in performance.  Now, users
can adjust it without recompilation.

This is YAASP (yet another Alan Stern patch).

According to James Bottomley, we need to notify the SCSI midlayer whenever
we issue a driver-initiated device reset.  That can happen in several
places, most notably following a transport error.  This patch adds
code to the reset routine to take care of it.  (Notifying about resets
requested by the midlayer itself is unnecessary but harmless.)

I've noticed in 2.6 kernels that HIDIOCGREPORT does not wait for io
completion before returning to the caller. This creates a few unpleasant
issues for userspace:

First, code sequences such as...

        ioctl(fd, HIDIOCGREPORT, &rinfo);
        ioctl(fd, HIDIOCGUSAGE, &uinfo);
        ioctl(fd, HIDIOCGSTRING, &sdesc);

...that used to work in 2.4 now fail in 2.6 if the device takes more
than a few milliseconds to respond to HIDIOCGREPORT. (I'm seeing this
issue on APC UPSes, FWIW.)

Second, userspace code can easily flood the kernel with control messages
since the kernel provides no "backpressure". The result is a lot of
"hid-core.c: control queue full" errors and lost reports.

2.6 hid-core.c appears to submit the request and return immediately.
Although the 2.4 code differs significantly, I traced the call path to
usb-core.c, which seems to block with a timeout, so the code supports my
userspace observation. (Assuming I didn't misread it.)

Patch from Frank Becker

Crud removal. Updated cerf doc.

The SA CerfPDA/CerfPOD have long been gone. I see no
community activity. The last official release was 2.4.9.

Removed ifdefs for CERF_CPLD (which referred to the PDA/POD), go figure.
Removed keyboard driver.
Removed default configs for PDA/POD.
Removed PDA/POD related LCD stuff.

Patch from Nicolas Pitre

Patch from Tony Lindgren

Following patch adds ARM710T processor support to proc-arm720.S.

The preferred way to add support was discussed on the Linux-arm-kernel
mailing list in December, with a link to the thread here:

http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2003-October/017596.html

NEC ARM710T is used in Psion Windermere architecture, and possibly
other systems.

710T works fine with the 720T functions, except the high_mapping
does not work for vectors_base(). Even if the high bit register is
set, the vectors stay at 0x00000000 instead of 0xffff0000.

Patch from Peter Teichmann

This adds German Umlauts (ÄÖÜäöüß) and some other Characters to the
Acorn 8x8 console font.

Patch from David Brownell

This patch adds the UDC driver itself.

Depends on the udc platform_data patch (#3 this series)
and on 1659/1 (kconfig/kbuild support).

SUPERCEDES patch 1658/1 (against test5)

Patch from David Brownell

This adds basic lubbock-specific customization for the UDC driver,
and makes it use INIT_MACHINE.

Depends on the INIT_MACHINE patch and the UDC platform_data patches
(#1, #3 in this series).

Be careful of patch conflicts applying to other kernels, mostly due
to different platform devices being listed.

Patch from David Brownell

This declares the pxa2xx_udc platform device, defines
the platform_data made available to that driver, and
allows different machines to customize that platform_data.

Same idea as in the FB driver.  Be careful of patch conflicts
applying to other kernels, mostly due to different platform
devices being listed.

This patch fixes a long-standing (albeit unidentified) problem in the
queueing code for the UHCI HCD.  The code propagates data toggle settings
between messages in a queue for control transfers just the same as bulk
and interrupt transfers.  That is a mistake, since control messages always
restart with data toggle 0.  With this patch, the UHCI driver now passes
test 10 (control URB queueing) in David Brownell's usbtest suite.

The patch appears to change more than it really does, because it alters
the indentation level of a large section of code.

non-fatal didn't get the same change that k7.c did a few months
back, so it reads from banks that actually _cause_ MCEs.

This patch also adds a bunch of copyright headers whilst we're
in that neighborhood.

In particular, load the host early in order to do proper
locking without having to access the command structure later.

This patch arranges for the exception tables to be sorted on most
architectures.  It sorts the main kernel exception table on startup
and the module exception tables when they get loaded.  The main table
is sorted reasonably early - just after kmem_cache_init - but that
could be moved even earlier if necessary.

There is now a lib/extable.c which includes the sort_extable()
function from arch/ppc/mm/extable.c and the search_extable() function
from arch/i386/mm/extable.c, which had been copied to many
architectures.  On many architectures, arch/$(ARCH)/mm/extable.c
became empty and so I have removed it.

There are four architectures which do things differently from i386:
alpha, ia64, sparc and sparc64.  Alpha and ia64 store the offset from
the offset from the exception table entry to the instruction, and
sparc and sparc64 have range entries in the table.  For those
architectures I have added empty sort_extable functions.  The
maintainers for those architectures can implement something better if
they care to.  As it is they are no worse off than before.

Although it is a moderately sizable patch, it ends up with a net
reduction of 377 lines in the size of the kernel source. :)

I have tested this on x86 and ppc with a module that uses __get_user
in an init function, deliberately laid out to get the exception table
out of order, and it works (whereas it oopsed without this patch).

This went missing somewhere.  Here's a patch which puts it back.

Sanitize 66MHz clock use: "enable" 66MHz clock before starting UDMA3/4/5
read/write transfer and "disable" it after finishing transfer.

- fixes timings for non-UDMA3/4/5 operations (correct 33MHz timings are used)

- allows using UDMA3/4/5 modes on a capable drive even if non-UDMA3/4/5 drive
  is present on the same channel

- fixes corner case when one drive on the channel was using UDMA66/100 + LBA48
  (so clock was enabled/disabled for each read/write) and other one was using
  UDMA66/100 + LBA28, it could happen that request on LBA48 drive disabled
  66MHz clock and it was not enabled for the next transfer on LBA28 drive

drive->id is now always present even if no device is attached,
therefore check for drive->present instead.

This fixes bugzilla bug #1431.

Always tune controller PIO timings.  This fixes lockup during PIO access
(ie. 'cat /proc/ide/hda/identify') when Promise BIOS is disabled.

When binding to a link-local address, inet6_bind() and raw6_bind() only
check that an interface is specified and that the address exists, but
they don't check if it actually exists on the specified interface.

Similarly, in datagram_sent_ctl() we don't check for the possibility of a
link-local address when we receive the source address from userspace.
