I tested these patches applied to v6.7-rc7 on PS3 with
CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2=y, and they seem to be working OK.  I did
not do any extensive testing though.

I tested three configurations:

 - With only the first patch 'Fix lv1 hcall assembly for ELFv2 calling
   convention' applied.

 - With the first two patches, 'Fix lv1 hcall assembly for ELFv2 calling
   convention' and 'lv1 hcall code use symbolic constant for LR save
   offset' applied.

 - And with all three patches applied.

All three configurations worked OK.  Thanks again for working on this.

Michael, I think we can just add these three patches and remove my patch that
disables CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2.
