I dug into this a bit more, and something has changed in master with respect to patch handling, I'm bisecting now to find the failure. Your patch when tested in the yocto bernard branch works fine, when I try it in yocto master, the patch is not propagated to the work dir so the tools can't pick it up and apply it to the BSP branch.

A patch specified in the SRC_URI will be picked up by the tools and applied to the end of the BSP branch during the patching phase. It has definitely worked during all the development cycles, so if you are seeing it not work, it's a bug and I'll fix it.

[OE-core] How to patch yocto kernel
Hi I am trying to test this patch http://uclibc.org/~kraj/perf-tool-Fix-gcc-4.6.0-issues.patch to fix the build using gcc 4.6.0 but the kernel patching for yocto is not as usual as other recipes since it uses entire set of tooling around it. I tried to look around for documentation and few references I found https://wiki.pokylinux.org/wiki/Wind_River_Kernel discourages putting patches in metadata. and in another document it says it uses git to do patching but does not explain how. So if someone can explain in simple terms how to patch a linux-yocto would be really helpful from a developer POV or any documentation will be helpful. How do people develop/test patches on linux-yocto I understand eventually they are desired to be part of linux-yocto git but that comes after they are tried and tested locally I would have preferred to have the usual SRC_URI patching atleast for local testing. As of now it seems not to use normal OE recipe procedures.
