update cpuinfo
Hi, I'm sorry for the ping here, but I was wondering if there're any estimated date for this to be merged? I understand that the risc-v architecture is not in the top tier of support, but as this should be a fairly small PR and would help others to build Tensorflow Lite for risc-v devices. :) Also I'll happy to bump this to the latest commit ([3c8b153](https://github.com/pytorch/cpuinfo/tree/3c8b1533ac03dd6531ab6e7b9245d488f13a82a5)) of `pytorch/cpuinfo` if you'd like me to do so. 😃 > Hi, I'm sorry for the ping here, but I was wondering if there're any estimated date for this to be merged?

Hi @cocoa-xu Sorry for the delay, we are working on this PR internally. Thank you for your contribution!  > > Hi, I'm sorry for the ping here, but I was wondering if there're any estimated date for this to be merged?

Got it! Thanks for your kind reply 😃
Update cpuinfo so that TensorFlow builds for riscv64 again, as PR https://github.com/pytorch/cpuinfo/pull/204 broke it for including the `<sys/hwprobe.h>` header, which only exists in the RISC-V Android NDK. It was fixed in https://github.com/pytorch/cpuinfo/pull/215.
