Patch from Lennert Buytenhek

This is an old patch from 2.6.9-rc3-ds2 that never made it upstream.
The IXP2000 slowport has two modes of operation, 8-bit and 32-bit.
The slowport itself is a byte-wide bus, and in 8-bit mode, it does the
more-or-less obvious thing: every word read causes four byte reads,
and those bytes are then combined into a word according to the xscale
core's current endian setting.  So, what value you get depends on what
endianity your IXP2000 is running in.
In 32-bit mode, however, it is the slowport itself which combines
bytes into words, and for this it unconditionally uses little endian
mode.  In this mode, word reads from the slowport will return the
same value no matter whether the xscale core is running in big or
little endian mode.  This can be a plus in some cases.  Byte (and
halfword) accesses in 32-bit mode have rather useless semantics
due to this, though.
The usefulness of 32-bit mode is limited to the initial boot.  When
the IXP2000 resets, the slowport is always in 32-bit mode, so if you
flash the bootloader into flash (which is connected to the slowport)
using little-endian byte ordering, the xscale will always read the
instruction stream correctly, no matter whether it's running in big
or little endian mode.
After booting it makes no sense to use 32-bit mode anymore.  Especially
since the slowport's word ordering in 32-bit mode is little endian,
and the IXP2000 is conventionally run in big endian, which gives all
kinds of fun issues when trying to access peripherals connected to
the slowport.
In fact, the current MTD map driver for IXP2000 already sets the
slowport to 8-bit mode because it cannot access the flash otherwise.
However, this means that if the MTD map driver is not compiled in for
some reason, the slowport will stay in 32-bit mode after the initial
boot, which will cause peripheral accesses to unexpectedly break!

I am awfully sorry, but that patch contained a bug. The code dereferenced
cmd->back as if it were a pointer to a request even when it wasn't. It worked
by accident, because rq->flags overlapped with a zeroed memory in other case.

This patch fixes a nasty bug that took us almost a week to track down on
ppc64, introduced by the 4L page table changes, and resulting in random
memory corruption. All archs that rely on a PTE page's struct page to
contain the mm & address (in mapping/index) will be affected.

zeromap_pud_range() is one of these page tables walking functions that
split the address into a base and an offset. It forgets to add back the
"base" when calling the lower level zeromap_pmd_range(), thus passing a
bogus virtual address. Most archs won't care, unless they do the above,
since the lower level can allocate a PTE page.

Kudo's to Michael Ellerman too who spent that week running tests after
tests to track it down, since the only way we managed to get it to show
up was after about 1 to 2h of LTP runs ...

(Note: We are in _urgent_ need to consolidate all those page table
walking functions, they all do things in a subtely different way, with
different checks (sometimes redudant) and inconsitent with each other,
even within a given set of them. Hopefully, Nick has some work in
progress there).

When using 4level-fixup.h, a PMD page may end up beeing freed before the
matching PGD entry is cleared due to the way the compatibility macros
work. This can cause nasty races on some architectures.

This patch fixes it by defining pud_clear() to be pgd_clear(). That
means we'll actually write 0 twice, a small price to pay here,
especially seeing how easy it is to convert to the new headers anyway
(hint hint, ppc & ppc64 patches as soon as 2.6.11 is out).

This gets rid of a bug found in some IRQ handling logic, after tripping
a debug assertion.  Basically, a recent patch called the wrong routine to
unlink a QH.  Net result, it wasn't allowing for the case that some other
QH was already being unlinked.  This patch uses the correct routine; the
names are confusingly similar, and the effect is often identical.

The consequence of using the wrong routine was that the driver could
lose one of the pending unlinks (probably wedging some activity) and
treat the other one as completed before it was safe to do so (which
probably wouldn't oops, but could cause other nasty corruption).

Implemented ACPI 3.0 support for implicit conversion within
the Match() operator. match_obj can now be of type
integer, buffer, or string instead of just type integer.
Package elements are implicitly converted to the type
of the match_obj. This change aligns the behavior of
Match() with the behavior of the other logical operators
(LLess(), etc.)  It also requires an errata change to the
ACPI specification as this support was intended for ACPI
3.0, but was inadvertently omitted.

Fixed a problem with the internal implicit "to buffer"
conversion.  Strings that are converted to buffers will
cause buffer truncation if the string is smaller than the
target buffer. Integers that are converted to buffers will
not cause buffer truncation, only zero extension (both as
per the ACPI spec.) The problem was introduced when code
was added to truncate the buffer, but this should not be
performed in all cases, only the string case.

Fixed a problem with the Buffer and Package operators
where the interpreter would get confused if two such
operators were used as operands to an ASL operator (such
as LLess(Buffer(1){0},Buffer(1){1}).  The internal result
stack was not being popped after the execution of these
operators, resulting in an AE_NO_RETURN_VALUE exception.

Fixed a problem with constructs of the form
Store(Index(...),...). The reference object returned from
Index was inadvertently resolved to an actual value. This
problem was introduced in version 20050114 when the
behavior of Store() was modified to restrict the object
types that can be used as the source operand (to match
the ACPI specification.)

Reduced stack use in acpi_get_object_info().

It appears that access to the PLL registers of the radeon chip is
unreliable while the card is in "legacy VGA" text mode. I don't have a
good explanation yet, it might be the BIOS mucking around behind my
back. This fixes the lockup by moving the code that enables/disables the
dynamic power management to after the mode is set.

I'm still waiting for a proper explanation from ATI...

Noted while going through the n_tty code: that buffer check
used to check against the size of the temporary kernel buffer,
but since the tty layer was changed to use kernel buffers
though-out, the kernel buffer array became just a pointer, and
the check was limiting the opost blocksize to the size of a
pointer, which makes no sense.

Just remove it, since now the whole buffer is always in kernel
space.
