Hi,

I have a 64 bits kernel running with 32 bits binaries.
If I run 32 bits perf on this 64 bits kernel 3.14, I got weird result :

- perf trace doesn't work [1]

I have patches that fix that:
git clone https://github.com/dsahern/linux.git
git checkout perf-full-monty

And if autodetection fails you can manually force it with -M x86.
