SVN rev 197442 on 2009-09-23 20:13:36Z by jkim
- Use spin lock instead of default mutex for safety. INT/IRET instructions
save/clear/restore flags but emulated flags have no effect on the host.
I believe BIOS writers never meant to run their code in emulated
environment with interrupt enabled. :-)
- Use memcpy(3) instead of copying individual members. I believe struct
x86regs was intentionally copied from the first half of struct x86emu_regs
for this very purpose.
- Fix some style nits and consistencies.
