I am preparing to convert the boot time page table to the kernels native format. To achieve that I need to enable PAE. Enabling PSE and the no execute bit would not hurt. So this patch modifies the boot cpu path to execute all of the kernels enable code if and only if we have the proper bits set in mmu_cr4_features. Signed-off-by: Eric W.
