28136775cd include/fpu/softfloat: implement float16_abs helper
This will be required when expanding the MINMAX() macro for 16
bit/half-precision operations.

24f91e81b6 target/*/cpu.h: remove softfloat.h
As cpu.h is another typically widely included file which doesn't need
full access to the softfloat API we can remove the includes from here
as well. Where they do need types it's typically for float_status and
the rounding modes so we move that to softfloat-types.h as well.

As a result of not having softfloat in every cpu.h call we now need to
add it to various helpers that do need the full softfloat.h
definitions.

cfd88fc6f2 fpu/softfloat-types: new header to prevent excessive re-builds
The main culprit here is bswap.h which pulled in softfloat.h so it
could use the types in its CPU_Float* and ldfl/stfql functions. As
bswap.h is very widely included this added a compile dependency every
time we touch softfloat.h. Move the typedefs for each float type into
their own file so we don't re-build the world every time we tweak the
main softfloat.h header.

a9579fff61 include/fpu/softfloat: remove USE_SOFTFLOAT_STRUCT_TYPES
It's not actively built and when enabled things fail to compile. I'm
not sure the type-checking is really helping here. Seeing as we "own"
our softfloat now lets remove the cruft.

7f1d87ab0f trace: avoid SystemTap "char const" warnings
SystemTap's dtrace(1) produces the following warning when it encounters
"char const" instead of "const char":

  Warning: /usr/bin/dtrace:trace-dtrace-root.dtrace:66: syntax error near:
  probe flatview_destroy_rcu

  Warning: Proceeding as if --no-pyparsing was given.

This is a limitation in current SystemTap releases.  I have sent a patch
upstream to accept "char const" since it is valid C:

  https://sourceware.org/ml/systemtap/2018-q1/msg00017.html

In QEMU we still wish to avoid warnings in the current SystemTap
release.  It's simple enough to replace "char const" with "const char".

I'm not changing the documentation or implementing checks to prevent
this from occurring again in the future.  The next release of SystemTap
will hopefully resolve this issue.

fb1a66bc01 tracetool: Update argument format regex to non-greedy star
Using the greedy star matching, arguments like "...%"PRIx64 caused issues
for functions with multiple PRI formats.

The issue was only seen with the ust backend, as it is the only one
using the format regex.

The result for many functions was that the arguments coming after the
greedy star end was left out of the tracepoint, and in some cases some
of the arguments that was traced had the wrong format.

919ae3dd11 hw/rdma: Implementation of PVRDMA device
PVRDMA is the QEMU implementation of VMware's paravirtualized RDMA device.
It works with its Linux Kernel driver AS IS, no need for any special
guest modifications.

While it complies with the VMware device, it can also communicate with
bare metal RDMA-enabled machines and does not require an RDMA HCA in the
host, it can work with Soft-RoCE (rxe).

It does not require the whole guest RAM to be pinned allowing memory
over-commit and, even if not implemented yet, migration support will be
possible with some HW assistance.

Implementation is divided into 2 components, rdma general and pvRDMA
specific functions and structures.

The second PVRDMA sub-module - interaction with PCI layer.
- Device configuration and setup (MSIX, BARs etc).
- Setup of DSR (Device Shared Resources)
- Setup of device ring.
- Device management.

This layer is composed of two sub-modules, backend and resource manager.
Backend sub-module is responsible for all the interaction with IB layers
such as ibverbs and umad (external libraries).
Resource manager is a collection of functions and structures to manage
RDMA resources such as QPs, CQs and MRs.

06329ccecf mem: add share parameter to memory-backend-ram
Currently only file backed memory backend can
be created with a "share" flag in order to allow
sharing guest RAM with other processes in the host.

Add the "share" flag also to RAM Memory Backend
in order to allow remapping parts of the guest RAM
to different host virtual addresses. This is needed
by the RDMA devices in order to remap non-contiguous
QEMU virtual addresses to a contiguous virtual address range.

Moved the "share" flag to the Host Memory base class,
modified phys_mem_alloc to include the new parameter
and a new interface memory_region_init_ram_shared_nomigrate.

There are no functional changes if the new flag is not used.

b44316fb36 linux-user: Remove THREAD macro
Back when we used to support compiling either with or without
NPTL threading library support, we used a macro THREAD which would
expand either to nothing (no thread support) or to __thread (threads
supported). For a long time now we have required thread support,
so remove the macro and just use __thread directly as other parts
of QEMU do.

Note that the 'Add test for migration to bad destination' displays
 a 'Connection refused' during running, but still gives the correct exit
 code and OK (It's checking that the source doesn't fail when
 it can't connect, so that's the right error).
 If it's particularly disliked that patch can be skipped individually.
