This is also do as the suggestion of "Linux Kernel Mentorship Task List"

https://wiki.linuxfoundation.org/lkmp/lkmp_task_list#cleanup_cppcheck_errors
"Shifting signed 32-bit value by 31 bits is undefined behaviour errors"

Change Log:

V2: Using BIT() macro instead of (1UL << nr) 

V3: 
* Update the comments from Russell King.
* Update commit message and cover letter for clearly the reason as request
  Peter Zijlstra
* For avoiding the broken only change (1<<nr) pattern to BIT(nr)
