[PATCH] powerpc: Fix asm offsets to point to actual FP and VMX regs
From: Michael Neuling <hidden>
Date: 2017-05-08 06:23:42
The asm code assumes the FP regs are at the start of fp_state. While this is true now, it may not always be the case and there is nothing enforcing it. This fixes the asm-offsets to point to the actual FP registers inside the fp_state. Similarly for VMX.
