In pre-SMPng, the global 'imen' was used to track mask state of the hardware interrupts and was aligned to the masks used by spl*(). When the atpic code was converted to using the x86 interrupt source abstraction, the global 'imen' was preserved by having each PIC instance point to an individual byte in the global 'imen' to hold its 8-bit interrupt mask. The global 'imen' is no longer used for anything however, so rather than storing pointers in 'struct atpic', just store the individual 8-bit mask for each PIC as a char. While here, convert the ATPIC macro to using C99 initializers. |
