This is a re-working of Paolo's eflags cleanup from October, which
I consider a pre-requisite to implementing the ADX extension. I've
rearranged most of the patches in trivial ways, and some quite
significantly.
I've tested the result by running the FC17 installer in both i386
and x86_64 mode, and the bmi/adx extensions with small user-land
test cases.
The patch series is at
git://github.com/rth7680/qemu.git eflags3
Please review.
