+// This is function to make a PAL procedure call. Based on the Index
+// value this API will make static or stacked PAL call. The following table
+// describes the usage of PAL Procedure Index Assignment. Architected procedures
+// may be designated as required or optional. If a PAL procedure is specified
+// as optional, a unique return code of 0xFFFFFFFFFFFFFFFF is returned in the
+// Status field of the PAL_CALL_RETURN structure.
+// This indicates that the procedure is not present in this PAL implementation.
+// It is the caller¡¯s responsibility to check for this return code after calling
+// any optional PAL procedure.
+// No parameter checking is performed on the 5 input parameters, but there are
+// some common rules that the caller should follow when making a PAL call. Any
+// address passed to PAL as buffers for return parameters must be 8-byte aligned.
+// Unaligned addresses may cause undefined results. For those parameters defined
+// as reserved or some fields defined as reserved must be zero filled or the invalid
+// argument return value may be returned or undefined result may occur during the
+// execution of the procedure. If the PalEntryPoint does not point to a valid
+// PAL entry point then the system behavior is undefined. This function is only
+// available on IPF.

+// On Entry :

+ Enables the 32-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. This function is
+ only available on IA-32. After the 32-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 NULL. The function
+ EntryPoint must never return.
+
+ There are a number of constraints that must be followed before calling this
+ function:
+ 1) Interrupts must be disabled.
+ 2) The caller must be in 32-bit protected mode with flat descriptors. This
+ means all descriptors must have a base of 0 and a limit of 4GB.
+ 3) CR0 and CR4 must be compatible with 32-bit protected mode with flat
+ descriptors.
+ 4) CR3 must point to valid page tables that will be used once the transition
+ is complete, and those page tables must guarantee that the pages for this
+ function and the stack are identity mapped.
+
