Re: [PATCH 1/7] Revert "riscv: Clear pending interrupts before enabling IPIs"

Hi Sean

Clearing MIP doesn't do anything. Whoops. The following commits should tackle this problem in a more robust manner.

I still not catch your points about that this commit 947263033 really help to fix pending IPIs not clean problem on k210 platform at that time, but you just said it do nothing and remove it here currently.

Thanks, Rick

This reverts commit 9472630337e7c4ac442066b5a752aaa8c3b4d4a6.
