From: Steve Muckle <smuckle@xxxxxxxxxxxxxx> The subarchitecture field in the fpsid register is 7 bits wide. The topmost bit is used to designate that the subarchitecture designer is not ARM. We use this field to determine which VFP version is supported by the CPU. Since the topmost bit is masked off we detect non-ARM subarchitectures as supporting only HWCAP_VFP and not HWCAP_VFPv3 as it should be for Qualcomm's processors. Use the proper width for the mask so that we report the correct elf_hwcap of non-ARM designed processors.
