                                behavior is considered to have
                                occurred if these
                                environmentally induced errors
                                cause the processor to deviate
                                from its normal execution and
                                eventually causes different

                                 at the processor bus pins.
                                Processor errors that do not
                                have this effects (i.e.,
                                software induced machine checks)
                                may or may not be promoted

  @param EnableVmsw   Bit54, Enable the use of the vmsw
                      instruction. When 0, the vmsw instruction

                      When 1, this bit will enable normal

                                    0, the processor may predict
                                    predicate results and

                                    instructions until the

  @param TestControl  This is an ordered implementation-specific
                      control word that allows the user control
                      over the length and runtime of the
                      processor self-tests. This control word is
                      ordered from the longest running tests up
                      to the shortest running tests with bit 0
                      controlling the longest running test. PAL
                      may not implement all 47-bits of the
                      test_control word. PAL communicates if a
                      bit provides control by placing a zero in
                      that bit. If a bit provides no control,
                      PAL will place a one in it. PAL will have
                      two sets of test_control bits for the two
                      phases of the processor self-test. PAL
                      provides information about implemented
                      test_control bits at the hand-off from PAL
                      to SAL for the firmware recovery check.
                      These test_control bits provide control
                      for phase one of processor self-test. It
                      also provides this information via the PAL
                      procedure call PAL_TEST_INFO for both the
                      phase one and phase two processor tests
                      depending on which information the caller
                      is requesting. PAL interprets these bits
                      as input parameters on two occasions. The
                      first time is when SAL passes control back
                      to PAL after the firmware recovery check.
                      The second time is when a call to
                      PAL_TEST_PROC is made. When PAL interprets
                      these bits it will only interpret
                      implemented test_control bits and will
                      ignore the values located in the
                      unimplemented test_control bits. PAL
                      interprets the implemented bits such that
                      if a bit contains a zero, this indicates
                      to run the test. If a bit contains a one,
                      this indicates to PAL to skip the test. If
                      the cs bit indicates that control is not
                       available, the test_control bits will be
                      ignored or generate an illegal argument in
                      procedure calls if the caller sets these
                      bits.

  @param ControlSupport   This bit defines if an implementation
                          supports control of the PAL self-tests
                          via the self-test control word. If
                          this bit is 0, the implementation does
                          not support control of the processor
                          self-tests via the self-test control
                          word. If this bit is 1, the
                          implementation does support control of
                          the processor self-tests via the
                          self-test control word. If control is
                          not supported, GR37 will be ignored at
                          the hand-off between SAL and PAL after
                          the firmware recovery check and the

/**
  Makes a PAL procedure call.

  This is a wrapper function to make a PAL procedure call.  Based on the Index value,
  this API will make static or stacked PAL call. 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 4 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.
  This function is only available on IPF.

  @param Index - The PAL procedure Index number.
  @param Arg2  - The 2nd parameter for PAL procedure calls.
  @param Arg3  - The 3rd parameter for PAL procedure calls.
  @param Arg4  - The 4th parameter for PAL procedure calls.

  @return structure returned from the PAL Call procedure, including the status and return value.
