Hello, can you mark the individual patches with RFC rather than the wole series?

Michal Suchánek's on September 24, 2019 7:33 pm: > Hello, > > can you mark the individual patches with RFC rather than the wole > series? Hey, thanks for the reviews. I'll resend all but the last two patches soon for merge in the next window. scv needs a bit more work but hopefully it will be mergeable as well but I will submit that afterward. Thanks, Nick
[RFC PATCH 00/27] current interrupt series plus scv syscall
My interrupt entry patches have finally collided with syscall and interrupt exit patches, so I'll merge the series. Most patches have been seen already, however there have been a number of small changes and fixes throughout the series. The final two patches add support for 'scv' and 'rfscv' instructions. I'm posting this out now so we can start considering ABI and userspace support. We have the PPC_FEATURE2_SCV hwcap for this.
