[ROSLOAD]: Implement OslExecuteTransition, OslArchKernelSetup,
ArchRestoreProcessorFeatures, OslArchTransferToKernel.
[ROSLOAD]: Factor out the logo code. Clean ups.
[ROSLOAD]: The IA32_MISC_ENABLE MSR bit actually _disables_ NX, so
diabling the bit _enables_ NX.
[ROSLOAD]: The MSR_XD_ENABLE_MASK is for the _high_ DWORD of the MSR
(bit 34), not the low.
[ROSLOAD]: Fix printf.
[ENVIRON/ROSLOAD]: Switch to CPU_INFO structure instead of blindly using
INT[4]. Revealed a bug in the PAE detection which was reading out of
bounds.
