Kernel: Change the way we call a syscall in signal_trampoline_dummy
The function signal_trampoline_dummy was using int 0x82 to call
SC_sigreturn. Since x86 is no longer supported, the correct way
to call a syscall is using the syscall instruction.
This paves the way to remove the syscall trap handling mechanism.
