I fixed it up (I just used the former as the latter seems to no longer be needed - I also undid the change to arch/riscv/Kconfig from the latter) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts.Agreed, it looks to me like I should drop my RISC-V change in favor of the native support. Please let me know if I am mistaken. If I do not hear otherwise, I will pull my commit out of -next in favor of those two on my next rebase.
Sorry I forgot to send the shared tag. We can pre-merge if you want, I'm fine either way just let me know.
Thanx, Paul
