Hi All,

Kernel compilation is failing with following error -

error: 'EM_RISCV' undeclared (first use in this function); did you mean 'EM_CRIS'?

Anyone seen this before ?

Thanks,
Amit

Can someone please suggest a working code in mptcp_net_next branch and how to download that ? I am looking to run mPTCP version 1 only.

hello @sdntechforum can you try appying upstream commit fe7118f4742f ? that should fix your error.

The upstream commit is in Linus' tree and I expect to be very soon in net-next, probably tomorrow in our export branch.
Because it is not related to MPTCP, I guess we can close this issue.
