From: 이경택 <gt82.lee@samsung.com> commit 0ab070917afdc93670c2d0ea02ab6defb6246a7c upstream. If regwshift is 32 and the selected architecture compiles '<<' operator for signed int literal into rotating shift, '1<<regwshift' became 1 and it makes regwmask to 0x0. The literal is set to unsigned long to get intended regwmask.
