svn commit: r306065 - in head/sys vs. PowerMacs: Nathan's trail patch included but inappropriate?

[Jukka A. Ukkonen]

FWIW my old PowerMac G4 ("Quicksilver") seems to be quite content
with this...

>>        __asm __volatile("mfsprg0 %0\n\t"
>>                         : "=&r"(ofw_sprg0_save)
>>                         :
>>                         );

I finally managed to get this tested yesterday evening.

Note! This G4 is still running 10.3-stable instead of 11.0-stable.
