This is a refresh of a David Daney's patch set to implement MIPS support
for perf. It has been posted before but not received any comments or
(N)Acks.
This series depends on
http://patchwork.linux-mips.org/patch/5246/
which currently is pending for 4.1 in the MIPS tree so I'd like to upstream
these two patches through the MIPS tree as well.
David's original patches are archived at:
http://www.linux-mips.org/cgi-bin/mesg.cgi?a=linux-mips&i=1368817238-11548-1-git-send-email-ddaney.cavm%40gmail.com
http://patchwork.linux-mips.org/patch/5249/
http://patchwork.linux-mips.org/patch/5250/
Cheers,
Ralf
