Bruce Evans 2088de1b49 Don't pass PSL_NT to vm86 signal handlers. Some vm86/real mode
programs, including msdos, set PSL_NT in probes for old cpu types,
although PSL_NT doesn't do anything useful in vm86 or real mode.
PSL_NT is even less useful in the signal handlers.  It just causes
T_TSSFLT faults on return from syscalls made by the handlers.
These faults are fixed up lazily so that Xsyscall() doesn't have
to be slowed down to prevent them.  The fault handler recently
started complaining about these faults occurring "with interrupts
disabled".  It should not have, but the complaints pointed to this
bug.
