SIESTATC is serialized in the following way:
- Testing or modifying SIERUNNING requires Dispatch Lock.
- Modifying any other bit requires Dispatch Lock AND
either Guest Instruction-stream or Console Function
Mode. Testing any of these other bits only requires
that 1 of the 3 previously mentioned serializations
is held.

SIxMODE and SIxMODEX contain bits
that can be used to determine the machine mode type.
[VMDBK only: In the state descriptions which VM imbeds in
(RGuest) VMDBKs, these bits should NOT be used for this
purpose anymore; instead, the HCPVMODE macro should be
used to test for machine modes: System-370, ESA/370,
ESA/XC. 370-XA machines are considered to be ESA/370.]

0004 4 Signed 4 SIEPREFX Guest prefix register value in
bits 1-18 or 1-19. The other bits
are not part of the prefix value
and must be masked off if
SIEPREFX is used as a full word
value. Either VMDPRFMK or MSKPFX
in HCPEQUAT may be used to
isolate the prefix value. MSKPFX
can be used to mask off the
non-prefix values. VMDPFXMK
should be used to also ensure the
correct value of bit 19 depending
on whether the guest is ESA/390
or z/Architecture mode.

.11. .... SIEICEXL X'60' SIEICEXL In SIE the
interception status is one byte,
x'51'. The XILC is bits 1 and 2
of that byte. A value in those
bits of 2 indicates the
interception was for an EX type
instruction. A value of 3 in
those bits indicates the
interception was for an EXRL type
instruction. ICEXL and ICEXS
describe this scenario.
.1.. .... SIEICEXS X'40' SIEICEXS The intercepted
Execute-type instruction has an
instruction length of 6 if bits 1
and 2 are on (a value of 3) and
ICEX is on. The Execute-type
instruction has an instruction
length of 4 if bit 1 is on and
bit 2 is off (a value of 2) and
if ICEX is on. These two bits are
only set if the
Execute-Extensions Facility is
