Strange code in head.S

While looking at head.S, I noticed that in the FTR Section
CPU_FTR_HAS_HIGH_BATS, the register used during all the mtspr
SPRN_DBATxx,r20 is r20.
But shouldn't it be r10 ?
In the 2.4 version it was r20 but for all the preceding code of
clear_bat, it has been replaced with r10 but not in the FTR ...
Maybe I'm wrong, I'm not working on an arch that uses it. It's just
seems strange to me ...
