Konstantin Belousov f98c3ea74e - When executing FreeBSD/amd64 binaries from FreeBSD/i386 or Linux/i386 ... processes, clear PCB_32BIT and PCB_GS32BIT bits [1]. - Reread the fs and gs bases from the msr unconditionally, not believing the values in pcb_fsbase and pcb_gsbase, since usermode may reload segment registers, invalidating the cache. [2]. Both problems resulted in the wrong fs base, causing wrong tls pointer be dereferenced in the usermode.
