Re: [PATCH] MIPS: perf: fix build failure

[Marcin Nowakowski <marcin.nowakowski@imgtec.com>]

Hi Sudip,

This patch fixes the build error, but leaves the I6500 handling incorrect.
I had explained to Ralf how the build should be fixed a while ago so 
hopefully he will fix it up in his -next branch (dd71e57bacb5 should 
have been applied on top of f7a31b5e7874, but in Ralf's tree 
f7a31b5e7874 is applied on v4.12-rc4 while dd71e57bacb5 is applied on 
v4.12-rc2).
You can see what those commits should look like by examining patchwork 
submissions (links available in commit descriptions).
