Plain text emails are usually wrapped at 72 characters. It makes it
easier to read the git log if you wrap lines.
Good job braving the nasty nest of #ifdefs in raw_getlength() :). The
code change looks good. Minor changes below - normally I'd make them
while merging your patch but I don't compile QEMU on Mac so I can't
compile test it. Please send a new version of this patch.

Not sure if tags are case-sensistive but it is usually written as
"Signed-off-by:". The git -s option does this for you, that's usually
more convenient than typing it out manually.

Please follow QEMU coding style and use lower_case_with_underscore
variable names.

No need to shadow the local variable that was already declared at the
top of the function. Please drop this.
