While reviewing the interrupt related code and register dump, we found couple of issues related to interrupt related register programming. Firstly, the function enabling/disabling the interrupts was trying to clear the interrupts which were not enabled in first place and secondly there is a potential race scenario between interrupt subroutine and interrupt enable/disable related functions as they both access interrupt registers without a common lock. This series addresses the aforementioned problems.
