This patch fixes the pa8800 at a gross level (there are still other
subtle incoherency issues which can still cause crashes and HPMCs).
What it does is try to force eject inequivalent aliases before they
become visible to the L2 cache (which is where we get the incoherence
problems).
A new function (parisc_requires_coherency) is introduced in
asm/processor.h to identify the pa8x00 processors (8800 and 8900)
which have the issue.

It seems PA7200 processors also suppress traps on loads to
%r0. This means we can prefetch for read on these cpus. Of course,
we can't support prefetch for write, since that requires
LOAD DOUBLEWORD which was added with PA2.0

asm/processor.h on parisc wants spinlocks for cpuinfo, but
linux/spinlock_types.h needs lockdep, and lockdep wants prefetch.
This leads to a horrible circular dependancy, because <asm/processor.h>
is including something which depends on things which are not defined
until the end of the file.
Kludge around this by moving prefetch related code into <asm/prefetch.h>
and including it before <linux/spinlock_types.h>, however this is just
a temporary solution until this mess can be cleaned up.

Currently the kernel audit system represents arch's as numbers and will
gladly accept comparisons between archs using >, <, >=, <= when the only
thing that makes sense is = or !=. I'm told that the next revision of
auditctl will do this checking but this will provide enforcement in the
kernel even for old userspace. A simple command to show the issue would
be to run
auditctl -d entry,always -F arch>i686 -S chmod
with this patch the kernel will reject this with -EINVAL

More than a little bit ugly, storing integers in void*, but at least the
code is correct, unlike some of the more crufty Linux kernel code found
elsewhere.
Rather than having two casts to massage the value into u32, it's easier
just to have a single cast and use "%lu", since it's just a printk.

Add QUICC Engine (QE) configuration, header files, and
QE management and library code that are used by QE devices
drivers.
Includes Leo's modifications up to, and including, the
platform_device to of_device adaptation:
"The series of patches add generic QE infrastructure called
qe_lib, and MPC8360EMDS board support. Qe_lib is used by
QE device drivers such as ucc_geth driver.
This version updates QE interrupt controller to use new irq
mapping mechanism, addresses all the comments received with
last submission and includes some style fixes.
v2: Change to use device tree for BCSR and MURAM;
Remove I/O port interrupt handling code as it is not generic
enough.
v3: Address comments from Kumar; Update definition of several
device tree nodes; Copyright style change."
In addition, the following changes have been made:
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o fixed qe_snums_init() serial num assignment to use a const array
o made CONFIG_UCC_FAST select UCC_SLOW
o reduced NR_QE_IC_INTS from 128 to 64
o remove _IO_BASE, etc. defines (not used)
o removed irrelevant comments, added others to resemble removed BD_ defines
o realigned struct definitions in headers
o various other style fixes including things like pinMask -> pin_mask
o fixed a ton of whitespace issues
o marked ioregs as __be32/__be16
o removed platform_device code and redundant get_qe_base()
o removed redundant comments
o added cpu_relax() to qe_reset
o uncasted all get_property() assignments
o eliminated unneeded casts
o eliminated immrbar_phys_to_virt (not used)
