Hello Raghavendra, That is exactly I had done albeit from menuconfig. Basically the whole point was to make sure my patch compiles against ARM11 architectures as well. Hence I ensured the .config contains the relevant flags on.
Most ARM11 implementations are ARMv6k, which has support for the instruction, but the older ARMv6 (without k) does not. From your description, I assume you only tested with ARMv6k, not ARMv6. Please enable the OMAP2 and IMX31 platforms to test ARMv6. Arnd
