- * The hypercall asms have to meet several constraints:
- * - Work on 32- and 64-bit.
- *    The two architectures put their arguments in different sets of
- *    registers.
- *
- * - Work around asm syntax quirks
- *    It isn't possible to specify one of the rNN registers in a
- *    constraint, so we use explicit register variables to get the
- *    args into the right place.
- *
- * - Mark all registers as potentially clobbered
- *    Even unused parameters can be clobbered by the hypervisor, so we
- *    need to make sure gcc knows it.
- *
- * - Avoid compiler bugs.
- *    This is the tricky part.  Because x86_32 has such a constrained
- *    register set, gcc versions below 4.3 have trouble generating
- *    code when all the arg registers and memory are trashed by the
- *    asm.  There are syntactically simpler ways of achieving the
- *    semantics below, but they cause the compiler to crash.
- *
- *    The only combination I found which works is:
- *     - assign the __argX variables first
- *     - list all actually used parameters as "+r" (__argX)
- *     - clobber the rest
- *
- * The result certainly isn't pretty, and it really shows up cpp's
- * weakness as as macro language.  Sorry.  (But let's just give thanks
- * there aren't more than 5 arguments...)
