Enables the 64-bit paging mode on the CPU. CR0, CR3, CR4, and the page tables
|

must be properly initialized prior to calling this service. This function
|

assumes the current execution mode is 32-bit protected mode with flat
|
||||
descriptors. This function is only available on IA-32. After the 64-bit
|
||||
paging mode is enabled, control is transferred to the function specified by
|
||||
EntryPoint using the new stack specified by NewStack and passing in the
|
||||
parameters specified by Context1 and Context2. Context1 and Context2 are
|
||||
optional and may be 0. The function EntryPoint must never return.
|

|

@param Cs The 16-bit selector to load in the CS before EntryPoint
|

is called. The descriptor in the GDT that this selector
|

references must be setup for long mode.
|

@param EntryPoint The 64-bit virtual address of the function to call with

the new stack after paging is enabled.

@param Context1 The 64-bit virtual address of the context to pass into

paging is enabled.
