* Flush PS/2 Devices on boot to avoid Locking dependent on the out buffer on real hardware / emulated PS2 over USB Removed Slow and Unnessisarty flipping causing kconsole write slowdowns consequently speeding up the boot process * sod wc * ignoring dynamically created objects, added make run rule which will automatically detect the platform and then use the correct platform rule * ACPI Power Shutdown
