#     powerpc/powernv: copy/paste - Mask SO bit in CR
#     
#     NX can set the 3rd bit in CR register for XER[SO] (Summary overflow)
#     which is not related to paste request. The current paste function
#     returns failure for a successful request when this bit is set. So mask
#     this bit and check the proper return status.
#     
#     Fixes: 2392c8c8c045 ("powerpc/powernv/vas: Define copy/paste interfaces")
