This adds support for tracing callchains for powerpc, both 32-bit
and 64-bit, and both in the kernel and userspace, from PMU interrupt
context.
The first three entries stored for each callchain are the NIP (next
instruction pointer), LR (link register), and the contents of the LR
save area in the
This provides a mechanism to allow the perf_counters code to access
user memory in a PMU interrupt routine on a 64-bit kernel. Such an
access can cause a SLB miss interrupt and/or a MMU hash table miss
interrupt.
An SLB miss interrupt on a user address will update the slb_cache and
slb_cache_ptr

Hi all,
The fixed link support is broken since The Big OF MDIO Rework,
the rework simply removed most of the code that was needed for
fixed links.
Too bad I didn't notice this earlier, I saw a bunch of patches
on the ml, but unfortunately I didn't look very close presuming
that Grant knew what he
