KATO Takenori 9ad861edee - For some old Cyrix CPUs, %cr2 is clobbered by interrupts. This ... problem is worked around by using an interrupt gate for the page fault handler. This code was originally made for NetBSD/pc98 by Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp> and has already been in PC98 tree. Because of this bug, trap_fatal cannot show correct page fault address if %cr2 is obtained in this function. Therefore, trap_fatal uses the value from trap() function. - The trap handler always enables interruption when buggy application or kernel code has disabled interrupts and then trapped. This code was prepared by Bruce Evans <bde@FreeBSD.org>. Submitted by: Bruce Evans <bde@FreeBSD.org> Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp>		1998-12-02 08:15:17 +00:00
