From 699d2937d45d9dabc1772d0d07501ccc43885c23 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Fri, 3 Oct 2008 22:00:32 +0200 Subject: traps: x86: converge trap_init functions - set_system_gate on i386 is really set_system_trap_gate - set_system_gate on x86_64 is really set_system_intr_gate - ist=0 means no special stack switch is done: - introduce STACKFAULT_STACK, DOUBLEFAULT_STACK, NMI_STACK, DEBUG_STACK and MCE_STACK as on x86_64. - use the _ist variants with XXX_STACK set to zero - remove set_system_gate Signed-off-by: Alexander van Heukelum Signed-off-by: Ingo Molnar traps: x86: correct copy/paste bug: a trap is a GATE_TRAP Fix copy/paste/forgot-to-edit bug in desc.h.
