Re: [PATCH 5/5] add setting gs/fsbase

FWIW, mach-bootstrap-hello is supposed to then echo back what you type
on the console, but it doesn't work. From some debugging, it seems
that once I input something, the following device_write () call hangs
here:

(gdb)
ast_taken () at ../kern/ast.c:88
88 if (reasons & AST_NETWORK)
(gdb)
96 if (self != current_processor()->idle_thread) {
(gdb) n
98 while (thread_should_halt(self))
(gdb) l
93 * or thread_block from the idle thread.
94 */
95
96 if (self != current_processor()->idle_thread) {
97 #ifndef MIGRATING_THREADS
98 while (thread_should_halt(self))
99 thread_halt_self(thread_exception_return);
100 #endif
101
102 /*
(gdb) bt
#0  ast_taken () at ../kern/ast.c:98
#1  0xffffffff81011b8e in _return_from_trap () at ../x86_64/locore.S:571
#2  0xffffffff9f442868 in ?? ()
#3  0xffffffff81018a70 in ?? () at ../kern/sched_prim.c:924
#4  0xffffffff9f43ffb8 in ?? ()
#5  0x0000000000000000 in ?? ()

I don't know what to make of that, but perhaps you will. Note that
again, this worked on i386.
