s390: add support for IBM z15 machines

2019-09-13T10:19:14+00:00

Add detection for machine types 0x8562 and 8x8561 and set the ELF platform
name to z15. Add the miscellaneous-instruction-extension 3 facility to
the list of facilities for z15.

And allow to generate code that only runs on a z15 machine.

s390: drop meaningless 'targets' from tools Makefile

2019-06-04T13:03:38+00:00

'targets' should be specified to include .*.cmd files to evaluate
if_changed or friends.

Here, facility-defs.h and dis-defs.h are generated by filechk.

Because filechk does not generate .*.cmd file, the 'targets' addition
is meaningless. The filechk correctly updates the target when its
content is changed.

s390: drop redundant directory creation from tools Makefile

2019-06-04T13:03:34+00:00

As you can see in scripts/Kbuild.include, the filechk creates the
parent directory of the target as needed.

This Makefile does not need to explicitly create the directory.

s390: drop unneeded -Wall addition from tools Makefile

2019-06-04T13:03:29+00:00

The top level Makefile adds -Wall globally for all host tools:

  KBUILD_HOSTCFLAGS   := -Wall -Wmissing-prototypes -Wstrict-prototypes -O2 \

I see two "-Wall" added for compiling these tools.

Of course, it is allowed to pass the same option multiple times, but
we do not need to do so.

s390: do not pass $(LINUXINCLUDE) to gen_opcode_table.c

2019-06-04T13:03:22+00:00

I guess HOSTCFLAGS_gen_opcode_table.o was blindly copied from
HOSTCFLAGS_gen_facilities.o

The reason of adding $(LINUXINCLUDE) to HOSTCFLAGS_gen_facilities.o
is because gen_facilities.c references some CONFIG options. (Kbuild
does not cater to this for host tools automatically.)

On the other hand, gen_opcode_table.c does not reference CONFIG
options at all. So, there is no good reason to pass $(LINUXINCLUDE).

KVM: s390: add deflate conversion facilty to cpu model

2019-04-25T06:24:17+00:00

This enables stfle.151 and adds the subfunctions for DFLTCC. Bit 151 is
added to the list of facilities that will be enabled when there is no
cpu model involved as DFLTCC requires no additional handling from
userspace, e.g. for migration.

Please note that a cpu model enabled user space can and will have the
final decision on the facility bits for a guests.
