Hello Bruce,
Just want to inform that I picked up Paul Charlie submission responsibilities
for LSI/AXXIA patches.
I checked the patches with checkpatch script and I verified these apply fine
on standard/axxia/base branch.
Topics:
- Update some RapidIO driver updates and errors fixes.
- Add new

commit 3e528cb7bae00ba0d73def6645d0f2fa906ee3e8 upstream
The bitfield allocation function returns error condition
as a negative value, but in two cases its result
was assigned to an unsigned member of the hw_perf_event
structure, thus the error would not be ever detected.

Change the log messages used in the RX path to be rate limited to avoid

Because CCN's cycle counter always runs, it will generate
an interrupt on overflow even if the relevant perf event
was not requested, causing a spurious warning message.
