081c11a5d0 [POWERPC] Fix 64 bits vDSO DWARF info for CR register
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) &regs->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)

f66bce5e6a [POWERPC] Add 1TB workaround for PA6T
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.

9697add0f8 [POWERPC] Quieten cache information at boot
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.

309a109255 [POWERPC] Enable SLUB in *_defconfig
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.

55347cc996 [POWERPC] ibmebus: Add device creation and bus probing based on of_device
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.

369d742def e1000e: don't poke PHY registers to retreive link status
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
avoid it alltogether by just using the MAC link bits to provide
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

7acb939130 [POWERPC] bestcomm: GenBD task support
This is the microcode for the GenBD task and the associated
support code. This is a generic task that copy data to/from
a hardware FIFO. This is currently locked to 32bits wide
access but could be extended as needed.

The microcode itself comes directly from the offical
API (v2.2)

2f9ea1bde0 [POWERPC] bestcomm: core bestcomm support for Freescale MPC5200
This patch adds support for the core of the BestComm API
for the Freescale MPC5200(b). The BestComm engine is a
microcode-controlled / tasks-based DMA used by several
of the onchip devices.

Setting up the tasks / memory allocation and all common
low level functions are handled by this patch.
The specifics details of each tasks and their microcode
are split-out in separate patches.

This is not the official API, but a much cleaner one.
(hopefully)

07e6e93136 [POWERPC] mpc52xx: Update mpc52xx_psc structure with B revision changes
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.

1088a20998 [POWERPC] rheap: Changes config mechanism
Instead of having in the makefile all the option that
requires rheap, we define a configuration symbol
and when needed we make sure it's selected.
