Modified Files: src/sys/kern: subr_cprng.c Log Message: Include MD machine/cpu_counter.h only if defined(__HAVE_CPU_COUNTER). XXX: Why not timecounter(9) but deprecated cpu_counter32() and microtime(9)? microtime(9) is part of timecounter(9). With extra overhead? There is no real replacement for cpu_counter32, which is doing a lot less processing than the alternatives. It seems used to get a random number and I think MI getbintime(9) is simple and enough. --- Izumi Tsutsui

Whee! This should fix all the vfork lossage! Any news on the addsi3 issue? christos
