[PATCH] x86_64: Clean up double fault handling
Since a double fault always implies that kernel data structures are corrupt, this fault should neither be handed to user mode handling, nor should the handler allow resuming the faulting code stream (since architecturally this isn't a fault, but an abort). Note that this slightly depends on the previously submitted patch adjusting the prototype of notify_die() (a compiler warning will result without that other patch). AK: Removed obsolete CONFIG_CHECKING code, added comments Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
