Eliminate redundant and incorrect booke206_page_size_to_tlb function from ppce500_spin.c in preference to previously existing but newly exported definition from e500.c Defect analysis: The booke206_page_size_to_tlb function in e500.c was updated in commit2bd9543"ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages" to reflect a change in the definition of MAS1_TSIZE_SHIFT from 8 (corresponding to a min TLB page size of 4kb) to a value of 7 (TLB page size 2k). The booke206_page_size_to_tlb() function defined in ppce500_spin.c was never updated to reflect the change in MAS1_TSIZE_SHIFT. In http://lists.nongnu.org/archive/html/qemu-ppc/2016-06/msg00533.html, Scott Wood suggested this "root cause" explanation: SW> The patch that changed MAS1_TSIZE_SHIFT from 8 to 7 was around the SW> same time as the patch that added this code, which is probably why SW> adjusting it got missed. Commit2bd9543cd3did update the SW> equivalent code in ppce500_mpc8544ds.c, which now resides in SW> hw/ppc/e500.c and has been changed to not assume a power-of-2 SW> size. The ppce500_spin version should be eliminated. Signed-off-by: Aaron Larson <alarson@ddci.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
