The current DWARF info for CR are incorrect, causing the gcc unwinder to
go to lunch if we take a segfault in the vdso. This fixes it.
Problem identified by Andrew Haley, and fix provided by Jakub Jelinek
(thanks !).
Unfortunately, a bug in gcc cause it to not quite work either, but that
is being fixed separately with something around the lines of:
linux-unwind.h:
fs->regs.reg[R_CR2].loc.offset = (long) ®s->ccr - new_cfa;
+ /* CR? regs are just 32-bit and PPC is big-endian. */
+ fs->regs.reg[R_CR2].loc.offset += sizeof (long) - 4;
(According to Jakub)

PA6T has a bug where the slbie instruction does not honor the large
segment bit. As a result, we have to always use slbia when switching
context.
We don't have to worry about changing the slbie's during fault processing,
since they should never be replacing one VSID with another using the
same ESID. I.e. there's no risk for inserting duplicate entries due to a
failed slbie of the old entry. So as long as we clear it out on context
switch we should be fine.

After 6 years the ppc64 kernel still thinks its important to tell me my
cache line size is 0x80 bytes. I think most people who care know that by
now. The rest probably cant even understand the hex output.
Since we might have misconfigured firmware or cpus that have a linesize
that isnt 128 bytes, I still print it out for those cases. If people
would prefer to remove it completely, lets do it.
Also for lpar remove the htab_address printout since its not used.

When checking out the new NO_HZ support in powerpc, I noticed we never
slept for more than 2 seconds. It turns out SLAB has a 2 second per cpu
timer that causes this.
After switching to SLUB I see some nice 4 second sleeps which is the
limit on this POWER6 box (the decrementer ticks at 512MHz):
slept 4.19 sec
slept 4.19 sec
slept 4.19 sec
slept 4.19 sec
slept 3.96 sec
slept 3.80 sec
slept 2.99 sec
Since SLUB is now the default and some powerpc defconfigs already enable
it, lets enable SLUB across the board for consistency. While doing this
I also noticed that the maple defconfig has SLAB debugging enabled which
is sure to make your box nice and slow. Fix that too.

The devtree root is now searched for devices matching a built-in whitelist
during boot, so these devices appear on the bus from the beginning. It is
still possible to manually add/remove devices to/from the bus by using the
probe/remove sysfs interface. Also, when a device driver registers itself,
the devtree is matched against its matchlist.

Remove old code that will be replaced by rewritten and shorter functions in
the next patch. Keep struct ibmebus_dev and struct ibmebus_driver for now,
but replace ibmebus_{,un}register_driver() by dummy functions. This way, the
kernel will still compile and run during the transition and git bisect will
be happy.

Extract generic of_device allocation code from of_platform_device_create()
and move it into of_device.[ch], called of_device_alloc(). Also, there's now
of_device_free() which puts the device node.
This way, bus drivers that build on of_platform (like ibmebus will) can
build upon this code instead of reinventing the wheel.

Apparently poking the link status registers when autonegotiation
is running on the PHY might botch the PHY link on 80003es2lan
devices. While this is a very rare condition we can completely

the proper information to ethtool.

main change:
* greatly improve per-NIC probe diagnostic output. Similar to other
net drivers, print out MAC address, PHY info, and various hardware and
software flags that may be relevant.
other changes:
* similar to other net drivers, only print the initial version message
when we have found at least one board.
* don't bother to print error message when pci_enable_device() fails,
it will do so for us.
* use dev_printk() rather than printk() in nv_probe(). This gives
use a standardized output similar to the rest of the kernel, and
eliminates the need to manually print out PCI bus id.
* use DRV_NAME constant where appropriate
* clean struct pci_driver indentation

On the mpc5200b the ccr register is 32 bits wide while on the
mpc5200 it's only 16 bits. It's up to the driver to use the
correct format depending on the chip it's running on.
The 5200b also offers some more registers & status in AC97
mode. Again, if not running on a 5200b the driver should not
use those.
