This patch fixes bits of the DRM so to make the radeon DRI work on
non-cache coherent PCI DMA variants of the PowerPC processors.
It moves the few places that needs change to wrappers to that
other architectures with similar issues can easily add their
own changes to those wrappers, at least until we have more useful
generic kernel API.

This interface was originally designed wrong, confusing bit-fields and
integers, major brown paper bag going back many years...
But userspace only ever used 4 values so fix the interface for new
users and fix the implementation to deal with the 4 values userspace
has ever emitted (0x1, 0x2, 0x3, 0x6).

This reverts commit b140b99c41.
[ conflict in drivers/ide/ide-probe.c fixed manually ]
It turned out that probing order change causes problems for some drives:
http://bugzilla.kernel.org/show_bug.cgi?id=10239
Since root causes are still being investigated and are unlikely to be fixed
before 2.6.25 lets revert this change for now. As a result cable detection
becomes less reliable when compared with 2.6.24 but the affected drives are
useable again.

There have been reported regressions of the SIL 680 driver when using MMIO, so
this makes it only try MMIO on Cell blades where it's known to be necessary
(the host bridge doesn't do PIO on these).
We'll try to find the root problem with MMIO separately.

This reorganization moves the PHY status into a separate
struct. Flow Control setup is moved into this struct as well
and frame size away from here into the adapter struct where its
inly use is.
The post-link-up code is now a separate function and moved out
of the watchdog function itself. This allows us to track the
es2lan restart issue a bit easier.

The functions time_before, time_before_eq, time_after, and time_after_eq are
more robust for comparing jiffies against other values.
So use the time_after() macro, defined in linux/jiffies.h, which deals with
wrapping correctly.

hibernation support for non-PnP ISA cards.

The asix usb driver currently depends on NET_ETHERNET which means you

drivers/net/pasemi_mac.c is enabled by CONFIG_PASEMI_MAC, which depends on
PPC64 && PCI. However pasemi_mac.c uses several routines that are only
built when PPC_PASEMI is selected. This can lead to an unbuildable config:
ERROR: ".pasemi_dma_start_chan" [drivers/net/pasemi_mac.ko] undefined!
So make CONFIG_PASEMI_MAC depend on PPC_PASEMI instead of PPC64.

If "location" is > "addr_len" bits, the high bits of location would interfere
with the READ_CMD sent to the eeprom controller.
A patch was submitted to bug:
http://bugzilla.kernel.org/show_bug.cgi?id=4420
which simply truncated the "location", read whatever was in "location
modulo addr_len", and returned that value. That avoids confusing the
eeprom but seems like the wrong solution to me.
Correct would be to not read beyond "1 << addr_len" address of the eeprom.
I am submitting two changes to implement this:
1) tulip_read_eeprom will return zero (since we can't return -EINVAL)
if this is attempted (defensive programming).
2) In tulip_core.c, fix the tulip_read_eeprom caller so they don't
iterate past addr_len bits and make sure the entire tp->eeprom[]
array is cleared.
I konw we don't strictly need both. I would prefer both in the tree
since it documents the issue and provides a second "defense" from
the bug from creeping back in.

And redirect sock_prot_inuse_add and _get to use one.
As far as the dereferences are concerned. Before the patch we made
1 dereference to proto->inuse.add call, the call itself and then
called the __get_cpu_var() on a static variable. After the patch we
make a direct call, then one dereference to proto->inuse_idx and
then the same __get_cpu_var() on a still static variable. So this
patch doesn't seem to produce performance penalty on SMP.
This is not per-net yet, but I will deliberately make NET_NS=y case
separated from NET_NS=n one, since it'll cost us one-or-two more
dereferences to get the struct net and the inuse counter.
