Detailed Description

template<typename ReduceType, typename Float2, typename FloatN>
struct quda::blas::xpyHeavyQuarkResidualNorm_< ReduceType, Float2, FloatN >

Variant of the HeavyQuarkResidualNorm kernel: this takes three arguments, the first two are summed together to form the solution, with the third being the residual vector. This removes the need an additional xpy call in the solvers, impriving performance.
