xtensa: userspace: use ADDX4 to calculate syscall table index When looking for jump address in the syscall table, we need to multiply the syscall ID by 4 before adding the address offset of the beginning of the table. This is due to the jump address being 32-bit (4 bytes). Instead of using two instructions to shift the ID by 4 first and then the addition, we can use one ADDX4 instruction to achieve the same result. Signed-off-by: Daniel Leung <daniel.leung@intel.com>
