Andreas Färber 49e158785f target-s390x: Pass S390CPU to s390_{add, del}_running_cpu()
This prepares for moving the halted field to CPUState.
Most call sites can already supply S390CPU, for some env becomes unused.

Andreas Färber f94667336e target-s390x: Clean up cpu_inject_*() signatures
Despite cautioning that S390CPU is needed for upcoming CPUState
refactorings, commit 5d69c547d9 (s390:
I/O interrupt and machine check injection.) added functions
cpu_inject_io() and cpu_inject_crw_mchk() with CPUS390XState argument,
claiming consistency with cpu_inject_ext().

This complicates making cpu_interrupt() take a CPUState even more and it
required to pass &cpu->env from some S390CPU-aware call sites already,
creating inconsistency elsewhere. Address that.

This also eliminates the need for CPUS390XState in s390_virtio_irq().

Andreas Färber c7396bbb25 target-s390x: Mark as unmigratable
CPU_SAVE_VERSION was undefined, so "cpu_common" VMState and
cpu_{save,load}() were not registered. They were no-ops.
Therefore there is no backwards compatibility to keep, so we can mark
S390CPU as unmigratable at device level.

Stefan Weil a158986d85 s390x: Remove inline function ebcdic_put and related data from cpu.h
The function is only used in misc_helper.c, so move it to that file.

This reduces the size of debug executables (compiled without optimization)
because they get unused code and data for each compilation which includes
cpu.h.

Executables with optimization don't change their size.

ebcdic2ascii is currently unused and could be removed (not done here).

The array ascii2ebcdic must be accessed with an unsigned index, therefore
(int)ascii[i] was replaced by (uint8_t)ascii[i]. The old code would have
failed for a signed char less than 0. The current code only converts
"QEMU" and spaces to EBCDIC, so there is no problem today.

Richard Henderson c95ec459c6 target-s390: Optimize ADDC/SUBB
Giving the proper mask to disas_jcc allows us to generate an inline
comparison generating the carry/borrow with setcond.

In the very worst case, when we must use the external helper to compute
a value for CC, we generate (cc > 1) instead of (cc >> 1), which is only
very slightly slower on common cpus.

In the very best case, when the CC comes from a COMPARE insn and the
compiler is using ALCG with zero, everything folds out to become just
the setcond that the compiler wanted.

Heinz Graalfs f6c98f9286 s390: sclp base support
This adds a more generic infrastructure for handling Service-Call
requests on s390. Currently we only support a small subset of Read
SCP Info directly in target-s390x. This patch provides the base
infrastructure for supporting more commands and moves Read SCP
Info.
In the future we could add additional commands for hotplug, call
home and event handling.

Christian Borntraeger 5b08b344bf s390: use sync regs for register transfer
Newer kernels provide the guest registers in kvm_run. Lets use
those if available (i.e. the capability is set). This avoids
ioctls on cpu_synchronize_state making intercepts faster.

In addition, we have now the prefix register, the access registers
the control registers up to date. This helps in certain cases,
e.g. for resolving kernel module addresses with gdb on a guest.

On return, we update the registers according to the level statement,
i.e. we put all registers for KVM_PUT_FULL_STATE and _RESET_STATE.

Avi Kivity a8170e5e97 Rename target_phys_addr_t to hwaddr
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific).  Replace it with a finger-friendly,
standards conformant hwaddr.

Outstanding patchsets can be fixed up with the command

  git rebase -i --exec 'find -name "*.[ch]"

The blank lines inside the single dump make it difficult for the
eye to pick out the block.  Worse, with interior newlines, but
no blank line following, the PSW line appears to belong to the
