Kristof Provost effd82ca70 dtrace: fix fbt return probes on RISC-V ... Return values are passed in a0, so read it from there. We also pass a1 through to userspace, as the ABI allows small structs to be returned in registers a0/a1. While here read the register values directly from the trapframe rather than rtval, and remove the now unneeded argument from dtrace_invop(). Set fbtp_roffset so that we get the correct return location in arg0. Reviewed by: markj Sponsored by: Axiado Differential Revision: https://reviews.freebsd.org/D26389		2020-09-11 09:15:49 +00:00
