KVM: s390: enable more features that need no hypervisor changes
After some review about what these facilities do, the following
facilities will work under KVM and can, therefore, be reported
to the guest if the cpu model and the host cpu provide this bit.
There are plans underway to make the whole bit thing more readable,
but its not yet finished. So here are some last bit changes and
we enhance the KVM mask with:
9 The sense-running-status facility is installed in the
z/Architecture architectural mode.
---> handled by SIE or KVM
10 The conditional-SSKE facility is installed in the
z/Architecture architectural mode.
---> handled by SIE. KVM will retry SIE
13 The IPTE-range facility is installed in the
z/Architecture architectural mode.
---> handled by SIE. KVM will retry SIE
36 The enhanced-monitor facility is installed in the
z/Architecture architectural mode.
---> handled by SIE
47 The CMPSC-enhancement facility is installed in the
z/Architecture architectural mode.
---> handled by SIE
48 The decimal-floating-point zoned-conversion facility
is installed in the z/Architecture architectural mode.
---> handled by SIE
49 The execution-hint, load-and-trap, miscellaneous-
instruction-extensions and processor-assist
---> handled by SIE
51 The local-TLB-clearing facility is installed in the
z/Architecture architectural mode.
---> handled by SIE
52 The interlocked-access facility 2 is installed.
---> handled by SIE
53 The load/store-on-condition facility 2 and load-and-
zero-rightmost-byte facility are installed in the
z/Architecture architectural mode.
---> handled by SIE
57 The message-security-assist-extension-5 facility is
installed in the z/Architecture architectural mode.
---> handled by SIE
66 The reset-reference-bits-multiple facility is installed
in the z/Architecture architectural mode.
---> handled by SIE. KVM will retry SIE
80 The decimal-floating-point packed-conversion
facility is installed in the z/Architecture architectural
mode.
---> handled by SIE
