kvm-x86: Remove eflags conversion into emulator format (Jan Kiszka)
It seems that the conversion of the kernel-delivered eflags state into qemu's internal split representation was once needed in an older kvm design (register read-back may have taken place from inside cpu_exec). Today it is plain wrong and causes incorrect cpu state reporting (gdb, monitor) and should also corrupt its saving (savevm, migration). Drop the related lines.
