From: Christoffer Dall christoffer.dall@linaro.org
commit fc396e066318c0a02208c1d3f0b62950a7714999 upstream.
We are incorrectly rearranging 32-bit words inside a 64-bit typed value for big endian systems, which would result in never marking a virtual interrupt as inactive on big endian systems (assuming 32 or fewer LRs on the hardware). Fix this by not doing any word order manipulation for the typed values.
