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.

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.

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.

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.

For very large framebuffers, it is theoretically possible for the result
of 'vs->throttle_output_offset * VNC_THROTTLE_OUTPUT_LIMIT_SCALE' to
exceed the size of a 32-bit int. For this to happen in practice, the
video RAM would have to be set to a large enough value, which is not
likely today. None the less we can be paranoid against future growth by
using division instead of multiplication when checking the limits.

Having analyzed the coredump, I understood that the reason is that
ioc_tag is reset on vnc_disconnect_start and ioc is cleaned
in vnc_disconnect_finish. Between these two events due to some
reasons the ioc_tag was set again and after vnc_disconnect_finish
the handler is running with freed ioc,
which led to the segmentation fault.
The patch checks vs->disconnecting in places where we call
qio_channel_add_watch and resets handler if disconnecting == TRUE
to prevent such an occurrence.

Commit 92b540dac9 introduce a counter to handle the timeouts in a
better way. But in case ccnt reaches 512, the current read character is
ignored - and if that character is part of the string that we are looking
for, the test fails to match the string.
Almost all of the tests look for a string within the first 512 bytes of
firmware output, so the problem never triggered there. But the hppa test
that has been added recently looks for a longer string at the very end of
a long output, thus there's a chance that we miss a character there so
that the test fails unexpectedly. Fix it by *not* reading and dropping a
character if the counter reaches 512.

The spapr-cap cap-ibs can only have values broken or fixed as there is
no explicit workaround required. Currently setting the value workaround
for this cap will hit an assert if the guest makes the hcall
h_get_cpu_characteristics.
Report an error when attempting to apply the setting with a more helpful
error message.

A few changes worth noting:
- Didn't migrate ctx->exception to DISAS_* since the exception field is
in many cases architecturally relevant.
- Moved the cross-page check from the end of translate_insn to tb_start.
- Removed the exit(1) after a TCG temp leak; changed the fprintf there to
qemu_log.

A couple of notes:
- removed ctx->nip in favour of base->pc_next. Yes, it is annoying,
but didn't want to waste its 4 bytes.
- ctx->singlestep_enabled does a lot more than
base.singlestep_enabled; this confused me at first.

Several places in the code need to calculate a VCPU id:
(cpu_index / smp_threads) * spapr->vsmt + cpu_index % smp_threads
(core_id / smp_threads) * spapr->vsmt (1 user)
index * spapr->vsmt (2 users)
or guess that the VCPU id of a given VCPU is the first thread of a virtual
core:
index % spapr->vsmt != 0
Even if the numbering logic isn't that complex, it is rather fragile to
have these assumptions open-coded in several places. FWIW this was
proved with recent issues related to VSMT.
This patch moves the VCPU id formula to a single function to be called
everywhere the code needs to compute one. It also adds an helper to
guess if a VCPU is the first thread of a VCORE.
