Marcel Moolenaar 79c3bcf42c In the nested TLB fault handler, for a direct-mapped address, make ... sure to clear the lower 12 bits. We're adding the translation attributes to the physical address and non-zero bits in the first 12 bits would give us something unexpected, including invalid bit values. Those trigger nested general protection faults. We do not have to clear the region bits, because they are ignored anyway, so we can replace an existing dep instruction with the one we need. This fixes GP faults for the swapper thread, as it's the only thread that has a direct-mapped stack. Since the bug is in the nested TLB fault handler, the frequency of hitting the GP is in the order of hours/days under load.		2014-01-15 03:57:41 +00:00
