Hi Andrew,
After merging the akpm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
arch/powerpc/mm/stab.c: In function '__ste_allocate':

Ok.
I will use sizeof(name) for snprintf() call.
Thanks.

When checking whether a bit representing a register is set in
sample_regs, a 64-bit mask, use 64-bit value (1LL).

When we try to create backtraces (call-graphs) with the perf tool
perf record -g /tmp/sprintft
we get backtraces with duplicate arcs for sprintft[1]:

Add ability to link with libunwind on Power.
This is based on similar changes in x86 and arm. Basically, implement
accessor functions that libunwind can call into while building the
backtrace from the user stack (which the kernel saved in a perf sample
- in previous commit).
Tested on Fedora-20 w
When requested, have the kernel save the user stack in each perf sample
so 'perf report' can use libunwind and produce better backtraces.
The downside of course is that the kernel has to copy the user-stack
on each sample which has both performance and file-size implications

I decided to run my tests on linux-next, and my wakeup_rt tracer was
broken. After running a bisect, I found that the problem commit was:
linux-next commit c365c292d059
"sched: Consider pi boosting in setscheduler()"
And the reason the wake_rt tracer test was failing, was because it had

Since sdhci_bcm_kona_sd_card_emulate() can be called from interrupt
context, we must use a spinlock instead of a mutex. This change
essentially restores the way things worked before the change to
mutexes in http://www.spinics.net/lists/linux-mmc/msg20276.html.
Without this change, we see "scheduli

The IBM PPC476GTR SoC that is used on the Akebono board uses a
different ethernet PHY interface that has wake on lan (WOL) support
with the IBM emac. This patch adds support to the IBM emac driver for
this new PHY interface.
At this stage the wake on lan functionality has not been implemented.

This patch adds support for PCI MSI with a new system device. The DMA

The IBM Akebono board is a development board for the new PPC476GTR
system on chip (SoC).
This version of the series updates the device tree and drops the USB
patches as the equivalent functionality is already in linux-next. It
also addresses feedback from the previous submission.

The IBM Akebono code uses the same initialisation functions as the
earlier Currituck board. Rather than create a copy of this code for
Akebono we will instead integrate support for it into the same file as
the Currituck code.
This patch just renames the board support file and updates the Makefile.
