bisect results for powerbook G4 not booting on latest git tree

[Aristeu Sergio Rozanski Filho]

Hi,
	I was unable to find someone who already did it, so here it
	the possible culprit of latest git tree (pulled both Linus' and
	Paul's tree) not booting on a powerbook G4:

a0652fc9a28c3ef8cd59264bfcb089c44d1b0e06 is first bad commit

    powerpc: Unify the 32 and 64 bit idle loops

    This unifies the 32-bit (ARCH=ppc and ARCH=powerpc) and 64-bit idle
    loops.  It brings over the concept of having a ppc_md.power_save
    function from 32-bit to ARCH=powerpc, which lets us get rid of
    native_idle().  With this we will also be able to simplify the idle
    handling for pSeries and cell.
