John Baldwin 62a08214bc Remove 'imen' global variable from atpic(4).
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 invididual 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.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
