Hi Vinod,

Hi Vinod Koul and Dan Williams,
Please have a look at these patches.
Note that patch 2~6 had beed sent out for upstream before, but were together
with other storage patches
The new ELFv2 little-endian ABI increases the stack redzone -- the
area below the stack pointer that can be used for storing data --
from 288 bytes to 512 bytes. This means that we need to allow more
space on the user stack when delivering a signal to a 64-bit process.
To make the code a bit clea

This enables support for userspace to fetch and initiate FSP and
Platform dumps from the service processor (via firmware) through sysfs.
Based on original patch from Vasant Hegde

- We register for OPAL notification events.
- OPAL sends new dump available notification.

pHyp can change cache nodes for suspend/resume operation. Currently the
device tree is updated by drmgr in userspace after all non boot CPUs are
enabled. Hence, we do not modify the cache list based on the latest cache
nodes. Also we do not remove cache entries for the primary

Sorry to update lately. It takes a long time to apply for test machine
and then, I hit a series of other bugs which I could not resolve
easily. And for now, I have some high priority task, and will come
back to this topic when time is available.
Besides this, I had do some basic test for numa-fault
The branch target should be the func addr, not the addr of func_descr_t.
So using ppc_function_entry() to generate the right target addr.
