| | | | | | | this hardware alive is becoming increasingly difficult, and I should heed the message sent by the three disks which have died on me over the last few days. Noone sane will mourn these ports anyway. So long, and thanks for the fish.
* Do not actually write to the area spanned by the PT_OPENBSD_RANDOMIZE ifmiod2014-02-251-5/+10
| | | | | LOAD_DATA is not set in flags; allows a two-pass kernel load using COUNT_KERNEL and then LOAD_KERNEL to work; similar to sparc loadfile_sparc.c 1.3.
