4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christoffer Dall <christoffer.dall@xxxxxxxxxx> 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.
