This PR include 2 changes to refine the testcases: 1. Now we using IPI to trigger interrupt in testing instead of INT instruction, this means we don't need to hardcode the vector number. That can avoid some problem. Fixes: #40374 2. Refined the test cases. Tigger interrupt by INT instruction and IPI cannot be masked by irq_disabled(). Unless it's a external interrupt, such as a timer. Now remove those incorrect part of these testcases. Signed-off-by: Enjia Mai <enjiax.mai@intel.com>
