Re: PATCH: Define DR_LEN_8 only if __x86_64__ is defined


The kernel doesn't actually constrain the dr7 value, so a user could use
DR_LEN_8 on 64-bit hardware (maybe even with a 32-bit kernel?).  But it
seems reasonable that in -m32 mode you are only encouraged to produce code
that actually works on 32-bit-only hardware.  So this is fine.
