svn commit: r234144 - in stable/9/sys: amd64/amd64 conf i386/conf i386/i386 i386/include kern pc98/pc98 x86/isa x86/x86

New Revision: 234144
URL: http://svn.freebsd.org/changeset/base/234144

Log:
  MFC 232744,232747,233031:
  - Allow a native i386 kernel to be built with 'nodevice atpic'.  Just as on
    amd64, if 'device isa' is present quiesce the 8259A's during boot and
    resume from suspend.
  - Move i386's intr_machdep.c to the x86 tree and share it with amd64.
  - Merge r232744 changes to pc98.
    (Allow a kernel to be built with 'nodevice atpic'.)
  - Move ICU related defines from x86/isa/atpic.c to x86/isa/icu.h and
    use them in x86/x86/intr_machdep.c.
  
  Note, I normally would have merged 232747 separately, but 233031 assumed
  232747 was already merged and 232744 needs to be merged with 233031.
