- from /proc/self/auxv. Or do the probing ourselves. The only thing
- extra that AT_HWCAP gives us is HWCAP_S390_HIGH_GPRS, which indicates
- that the kernel saves all 64-bits of the registers around traps while
- in 31-bit mode. But this is true of all "recent" kernels (ought to dig
- back and see from when this might not be true). */
