This makes for better messages on what is going on. It also
allows us (if we want to), to pick the PCI starting address
somewhere else in the gap. That may be a good idea (ie do a

	pci_mem_start = (gapstart + (gapsize >> 3) + 0xfffff) & ~0xfffff;

or similar.

We really don't care about anything beyond the 4GB mark,
so make the tests for that explicit (and add a comment),
and use regular "unsigned long" for the gap information.

A conflict between X and radeonfb can cause system memory corruption
when switching console from X (note that this is not realted to the
recent radeonfb patches, the problem has been there forever as far as I
can tell).

This patch works around it in radeonfb by making sure the "offsets"
register that driver the memory mapping of the accel engine are always
properly set before every accel op. A better fix should be done in fbcon
ultimately.

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!

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).
