The SPI0 block is not at all connected to the AB8500 on the

on the header may also be used for GPIO, but let's assume
that SPI is a probable usecase on the Snowball and mux in the

This moves the SKE keypad pin control table out of the board
file and into the device tree. This was previously set to be
active on all MOP500 and HREF boards but after reading the
schematic this seems incorrect: the HREFv60 and later uses
one of these for MC5 and no reference designs have the SKE
connected to any hardware so just leave the pins alone
in the power-on state.

This moves the MCDE pin control table out of the board file
and into the device tree. Some pins and configs have been
marked as used by sub-devices or slaves to the MCDE, such
as I2C device 0-070 which is the HDMI interface circuit
AV8100, but the pins rather belong to the MCDE SOC block
as they come out of the main ASIC. The touch screen GPIO
is not related to MCDE so this gets deleted and need to
be tied to the respective touch screen (I2C) device
once that device is added instead.

As we need to connect resources such as pin mappings and clocks
when deleting board files, we create a MCDE node even though there
is no driver for it. As it is only using standard bindings right
now, this does not matter much. When a proper driver is written
for the MCDE, it can augment this node with custom properties.

There are two code paths how page with pmd page table can be freed:
pmd_free() and pmd_free_tlb().
I've missed the second one and didn't add page table destructor call
there. It leads to leak of page->ptl for pmd page tables, if
dynamically allocated page->ptl is in use.
The patch adds the missed destructor and modifies documentation
accordingly.

The VSX MSR bit in the user context indicates if the context contains VSX
state. Currently we set this when the process has touched VSX at any stage.
Unfortunately, if the user has not provided enough space to save the VSX state,
we can't save it but we currently still set the MSR VSX bit.
This patch changes this to clear the MSR VSX bit when the user doesn't provide
enough space. This indicates that there is no valid VSX state in the user
context.
This is needed to support get/set/make/swapcontext for applications that use
VSX but only provide a small context. For example, getcontext in glibc
provides a smaller context since the VSX registers don't need to be saved over
the glibc function call. But since the program calling getcontext may have
used VSX, the kernel currently says the VSX state is valid when it's not. If
the returned context is then used in setcontext (ie. a small context without
VSX but with MSR VSX set), the kernel will refuse the context. This situation
has been reported by the glibc community.
Based on patch from Carlos O'Donell.

Up until now we have only used cpu_to_chip_id() in the topology code,
which is only used on SMP builds. However my recent commit a4da0d5
"Implement arch_get_random_long/int() for powernv" added a usage when
SMP=n, breaking the build.
Move cpu_to_chip_id() into prom.c so it is available for SMP=n builds.
We would move the extern to prom.h, but that breaks the include in
topology.h. Instead we leave it in smp.h, but move it out of the
CONFIG_SMP #ifdef. We also need to include asm/smp.h in rng.c, because
the linux version skips asm/smp.h on UP. What a mess.

I encountered following issue:
[ 0.283035] ibmvscsi 30000015: couldn't initialize event pool
[ 5.688822] ibmvscsi: probe of 30000015 failed with error -1
which prevents the storage from being recognized, and the machine from
booting.
After some digging, it seems that it is caused by commit 4886c399da
as dma_mask pointer in viodev->dev is not set, so in
dma_set_mask_and_coherent(), dma_set_coherent_mask() is not called
because dma_set_mask(), which is dma_set_mask_pSeriesLP() returned EIO.
While before the commit, dma_set_coherent_mask() is always called.
I tried to replace dma_set_mask_and_coherent() with
dma_coerce_mask_and_coherent(), and the machine could boot again.

Commit fba2369e6c (mm: use vm_unmapped_area() on powerpc architecture)
has a bug in slice_scan_available() where we compare an unsigned long
(high_slices) against a shifted int. As a result, comparisons against
the top 32 bits of high_slices (representing the top 32TB) always
returns 0 and the top of our mmap region is clamped at 32TB
This also breaks mmap randomisation since the randomised address is
always up near the top of the address space and it gets clamped down
to 32TB.
