    Check hyp_stack_switch return
    
    * i386/i386/pcb.c (switch_ktss): Check value returned by hyp_stack_switch.

commit 57c69b08378fc5b29f39227e8692a997f2374e31

commit d62085e5c5eb47cc2442899b125c799cb90e6d7b
Author: Samuel Thibault <address@hidden>
Date:   Fri Apr 6 21:17:05 2012 +0200

    Do not take address of va_list variable
    
    This breaks on x86_64, where it is an array and thus gets bogus results.
    
    * ddb/db_output.c (db_printf, kdbprintf): Pass copy of va_list variable 
instead
    of its address.
    * kern/debug.c (panic, log): Likewise.
    * kern/printf.c (vprintf, iprintf, sprintf, vsnprintf): Likewise.
    (_doprnt): Take va_list instead of va_list *, fix usage and comment 
accordingly.
    * kern/printf.h (_doprnt): Take va_list instead of va_list *.
