Justin T. Gibbs 7e2a739f03 Fix assertion failure when using userland DTrace probes from ... the pid provider on a kernel compiled with INVARIANTS. sys/cddl/contrib/opensolaris/uts/intel/dtrace/fasttrap_isa.c: In fasttrap_probe_pid(), attempts to write to the address space of the thread that fired the probe must be performed with the process of the thread held. Use _PHOLD() to ensure this is the case. In fasttrap_probe_pid(), use proc_write_regs() instead of calling set_regs() directly. proc_write_regs() performs invariant checks to verify the calling environment of set_regs(). PROC_LOCK()/UNLOCK() around the call to proc_write_regs() so that it's invariants are satisfied.
