Andy Lutomirski 7d8d8cfdee x86/doublefault/32: Rewrite the x86_32 #DF handler and unify with 64-bit ... The old x86_32 doublefault_fn() was old and crufty, and it did not even try to recover. do_double_fault() is much nicer. Rewrite the 32-bit double fault code to sanitize CPU state and call do_double_fault(). This is mostly an exercise i386 archaeology. With this patch applied, 32-bit double faults get a real stack trace, just like 64-bit double faults.
