Haren Myneni	146e9f1b65	crypto/nx: Add P9 NX specific error codes for 842 engine ... This patch adds changes for checking P9 specific 842 engine error codes. These errros are reported in coprocessor status block (CSB) for failures.

Haren Myneni	6333ed8f26	crypto: nx-842 - Mask XERS0 bit in return value ... NX842 coprocessor sets 3rd bit in CR register with XER[S0] which is nothing to do with NX request. Since this bit can be set with other valuable return status, mast this bit. One of other bits (INITIATED, BUSY or REJECTED) will be returned for any given NX request.

Dan Streetman	edc424f8cd	powerpc: Add ICSWX instruction ... Add the asm ICSWX and ICSWEPX opcodes. Add definitions for the Coprocessor Request structures needed to use the icswx calls to coprocessors. Add icswx() function to perform the ICSWX asm using the provided Coprocessor Command Word value and Coprocessor Request Block structure. This is required for communication with the NX-842 coprocessor on a PowerNV system.
