Module Name:    src

Modified Files:
        src/sys/arch/powerpc/ibm4xx: clock.c intr.c
        src/sys/arch/powerpc/include/ibm4xx: ibm4xx_intr.h

Log Message:
Make sure we mask statclock timer on ibm4xx systems. This avoids
pthread "related" panics like:

    panic: remrunqueue: bit 18 not set
    Stopped in pid 479.3 (exsprite) at      netbsd:cpu_Debugger+0x10:       lwz

               r1=0x445fff40 cr=0x40000002 xer=0 ctr=0x41aae208 esr=0 pid=0x36

While there, cleanup IPL_ definitions somewhat and fix interrupt mask
calculation per spl(9).
