Add test case running code interacting with registers within a
ucontrol VM.
* Add uc_gprs test case
The test uses the same VM setup using the fixture and debug macros
introduced in earlier patches in this series.

: PRINT_HEX with 512 bytes
* print_run: use print_psw and print_hex to print contents of VM run
state and SIE state description
* print_regs: print content of general and control registers
All prints use pr_debug for the output and can be configured using
DEBUG.

atomicity for the flags.
With the userspace definition of the SIE block layout now being present
we can reuse the values in other tests where applicable.

architecture specific defines that are now used in multiple test cases.
Christoph Schlameuss (9):
selftests: kvm: s390: Define page sizes in shared header
selftests: kvm: s390: Add kvm_s390_sie_block definition for userspace
tests
selftests: kvm: s390: Add s390x ucontrol test suite with
containing CONFIG_KVM_S390_UCONTROL.
This config needs to be set to built-in (y) as this cannot be built as
module.

Multiple test cases need page size and shift definitions.
By moving the definitions to a single architecture specific header we
limit the repetition.
Make use of PAGE_SIZE, PAGE_SHIFT and PAGE_MASK defines in existing
code.
