The Linux kernel turns space-register hashing off unconditionally at bootup. That code was provided by HP at the beginning of the PA-RISC Linux porting effort, and I don't know why it was decided then why Linux should not use space register hashing. 32-bit HP-UX versions seem to not use space register hashing either. But for 64-bit HP-UX versions, Sven Schnelle noticed that space register hashing needs to be enabled and is required, otherwise the HP-UX kernel will crash badly. On 64-bit CPUs space register hashing is controlled by a bit in diagnose register %dr2. Since we want to support Linux and 32- and 64-bit HP-UX, we need to fully emulate the diagnose registers and handle specifically the bit in %dr2. This patch adds the code to calculate the gva memory mask based on the space-register hashing bit in %dr2 and the PSW_W (64-bit) flag. The value is cached in the gva_offset_mask variable in CPUArchState and recalculated at every modification of the CPU PSW or %dr2.
