Incorporating review from v14. Lots of little changes, plus
a reorg of how exceptions implementing the atomic insns for
userland are generated.

Is it any more efficient to use multiplies instead of looping, as in:
uint64_t m;
b &= 7;
m = 0x0101010101010101ULL * ((1 << (8 - b)) - 1);
return (a & m) << b;
Or if multiplies are bad, what about straight-line expansion of the
mask, as in:
uint64_t m;
b &= 7;
m = (1 << (8 - b)) - 1;
m |= m << 32;
m |= m << 16;
m |= m << 8;
return (a & m) << b;

The multiply will (likely) be expanded by the compiler to the shift, but yes, I
should have played the mask game after Peter pointed out that this wasn't a
per-element variable shift in v14.

Thank you for your careful notification. :-)
I guess, it will be modified by RTH, before the patches v15 (or v16) are
integrated into qemu master tree.
If I should do anything for it, please let me know.
Thanks

I think this is OK, but you should fold the parts that are
changing earlier patches back into those patches
(and/or delete the code in the earlier patches so this
patch is just adding new code, not deleting old stuff).
