That's now a 404, strangely.  Did you mean "[PATCH 0/2] Fix indirect
syscall handler for syscalls with > 4 args"?

James - assuming I guessed correctly above, why is it that the second
patch "MIPS: Remove pt_regs adjustments in indirect syscall handler"
hasn't been applied?  Was this fixed some other way upstream?

Hmm, I may have made a typo with that link. Here's the real one:
https://www.linux-mips.org/archives/linux-mips/2017-03/msg00575.html

I've just tried with v4.13-rc1 and the bug is still not fixed there. My
guess is that the first patch is more obviously correct than the second
one so was applied first. I have never received any feedback on these
patches so I don't actually know why only one of them was applied.

Thanks,
James

I'm certainly not able to review this patch, so I won't apply it until
it's either accepted upstream or reviewed by Aurelien or another MIPS
porter.
