 Log Message:
 amdgpu: Mark float-dependent variables volatile.
 
 This way they are computed -- using FP instructions -- before
 DC_FP_END, after which point FP instructions will trap or behave
 unpredictably.
 
 This is a workaround, not a proper solution -- really, the
 DC_FP_START/END calls should happen in a separate compilation unit
 built without -mhard-float or whatever, but that's a lot more work to
 make happen for now.
