* 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc: (202 commits)
[POWERPC] Fix compile breakage for 64-bit UP configs
[POWERPC] Define copy_siginfo_from_user32
[POWERPC] Add compat handler for PTRACE_GETSIGINFO
[POWERPC] i2c: Fix build breakage introduced by OF helpers
[POWERPC] Optimize fls64() on 64-bit processors
[POWERPC] irqtrace support for 64-bit powerpc
[POWERPC] Stacktrace support for lockdep
[POWERPC] Move stackframe definitions to common header
[POWERPC] Fix device-tree locking vs. interrupts
[POWERPC] Make pci_bus_to_host()'s struct pci_bus * argument const
[POWERPC] Remove unused __max_memory variable
[POWERPC] Simplify xics direct/lpar irq_host setup
[POWERPC] Use pseries_setup_i8259_cascade() in pseries_mpic_init_IRQ()
[POWERPC] Turn xics_setup_8259_cascade() into a generic pseries_setup_i8259_cascade()
[POWERPC] Move xics_setup_8259_cascade() into platforms/pseries/setup.c
[POWERPC] Use asm-generic/bitops/find.h in bitops.h
[POWERPC] 83xx: mpc8315 - fix USB UTMI Host setup
[POWERPC] 85xx: Fix the size of qe muram for MPC8568E
[POWERPC] 86xx: mpc86xx_hpcn - Temporarily accept old dts node identifier.
[POWERPC] 86xx: mark functions static, other minor cleanups
...
None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

* Initialize IDE ports in mpc8xx_ide_probe().
* Remove m8xx_ide_init() and ppc_ide_md hooks - no need for them
(IDE mpc8xx host driver takes care of all this setup).
* Remove needless 'if (irq)' and 'if (data_port >= MAX_HWIFS)' checks
from m8xx_ide_init_hwif_ports().
* Remove 'ctrl_port' and 'irq' arguments from m8xx_ide_init_hwif_ports().
* Rename m8xx_ide_init_hwif_ports() to m8xx_ide_init_ports().
* Add __init tag to m8xx_ide_init_ports().
This patch fixes hwif->irq always being overriden to 0 (== auto-probe, is
this even working on PPC?) because of ide_init_default_irq() call in ide.c.
There should be no other functional changes.

There are no "default" IDE ports on PPC4xx so ppc4xx_ide_init_hwif_ports() is
unnecessary, remove it. Also remove no longer needed <linux/ide.h> include.
There should be no functional changes caused by this patch.

Rename commproc.[ch] to cpm1.[ch] to be more consistent with cpm2. Also
rename cpm2_common.c to cpm2.c as suggested by Scott Wood. Adjust the
includes accordingly.

m8xx_pic_init calls both mpc8xx_pic_init and cpm_pic_init. Renaming the
function to use the same name space as the rest of the mpc8xx
specific funtions and to be more meaningful.
m8xx_pic_init is declared in ppc8xx_pic.h but defined nowhere in the ppc
tree. Remove it.

PSC drivers should not access the CDM registers directly. Instead provide
a common routine for setting the PSC clock parameters with the required
locking.

I2C adapter drivers are supposed to handle retries on nack by themselves
if they do, so there's no point in setting .retries if they don't.
As this retry mechanism is going away (at least in its current form),
clean this up now so that we don't get build failures later.

All kobjects require a dynamically allocated name now. We no longer
need to keep track if the name is statically assigned, we can just
unconditionally free() all kobject names on cleanup.

The casting is safe only when the list_head member is the first member
of the structure, and even then it is better to use the address of the
list_head structure member.

The ml300 and ml403 xparameters.h files use different macros for the
AC97 interrupt pin assignments. This normalizes them to a canonical
value similar to what EDK generates for most other devices. This is
needed to get ml300 support to compile in arch/ppc.

Since commit 76d2160147, the NE2000 card
is not working anymore on PPC and POWERPC and produces WATCHDOG
timeouts.
The patch below fixes that the same way it has been done on x86, x86_64
and MIPS.

Reverts commit a15da8eff3
This driver is used by devices other than the xilinx opb-uartlite which
depend on bytewise access to the registers. The change to 32 bit access
does not work on these devices.

The Uartlite data sheet defines the registers as 32 bit wide. This
patch changes the register access to use 32 bit transfers and eliminates
the magic +3 offset which is currently required to make the device
work.
