[Qemu-devel] [PATCH] i386: Rename bools in PCMachineState to end in _enabled

[minyard@acm.org]

From: Corey Minyard <cminyard@mvista.com>

This makes their function more clear and prevents conflicts when adding
the actual devices to the machine state, if necessary.

I have this change in my tree because I have SMBus ACPI support
for an SMBus IPMI device.  Thus I need to add the smbus to the
PC machine state and it seems better to have the device named
"smbus" and the enable named "smbus_enabled".

However, I think this change makes the code more consistent and
clear.  Thus I am sending it separately.
