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 <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu> traps: x86: correct copy/paste bug: a trap is a GATE_TRAP Fix copy/paste/forgot-to-edit bug in desc.h. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
