For the downstream distribution of QEMU, we want to compile without
CONFIG_PARALLEL. Commit 9157eee1b1 already moved the function
parallel_hds_isa_init() (which is still required for linking) into a file
that is included anyway, but commit bb3d5ea858 moved it
to a separate file which is only compiled again if CONFIG_PARALLEL is
set. To be able to link QEMU again without CONFIG_PARALLEL, the file
should be considered for linking for all targets that have CONFIG_ISA_BUS.
And while we're at it, add a proper comment in there with the rationale
for the separate file.

The RAM device presents a memory region that should be handled
as an IO region and should not be pinned.
In the case of the vfio-pci, RAM device represents a MMIO BAR
and the memory region is not backed by pages hence
KVM_MEMORY_ENCRYPT_REG_REGION fails to lock the memory range.

Currently, a callback registered through the RAMBlock notifier
is not able to get the memory region type (i.e callback is not
able to use memory_region_is_ram_device function). This is
because mr->ram assignment happens _after_ the memory is allocated
whereas the callback is executed during allocation.

For devices that require msi_init/msix_init to succeed, add a
dependency on CONFIG_MSI_NONBROKEN. This will prevent those devices
from appearing in a binary that cannot instantiate them.

Not all interrupt controllers have a working implementation of
message-signalled interrupts; in some cases, the guest may expect
MSI to work but it won't due to the buggy or lacking emulation.
In QEMU this is represented by the "msi_nonbroken" variable. This
patch adds a new configuration symbol enabled whenever the binary
contains an interrupt controller that will set "msi_nonbroken". We
can then use it to remove devices that cannot be possibly added
to the machine, because they require MSI.

Set msi_nonbroken as true for the PLIC.
According to the comment located here:
https://git.qemu.org/?p=qemu.git;a=blob;f=hw/pci/msi.c;h=47d2b0f33c664533b8dbd5cb17faa8e6a01afe1f;hb=HEAD#l38
the msi_nonbroken variable should be set to true even if they don't
support MSI. In this case that is what we are doing as we don't support
MSI.

Bastian: this patchset converts the RISC-V decoder to decodetree in four major steps:
1) Convert 32-bit instructions to decodetree [Patch 1-15]:
Many of the gen_* functions are called by the decode functions for 16-bit
and 32-bit functions. If we move translation code from the gen_*
functions to the generated trans_* functions of decode-tree, we get a lot of
duplication. Therefore, we mostly generate calls to the old gen_* function
which are properly replaced after step 2).
Each of the trans_ functions are grouped into files corresponding to their
ISA extension, e.g. addi which is in RV32I is translated in the file
'trans_rvi.inc.c'.
2) Convert 16-bit instructions to decodetree [Patch 16-18]:
All 16 bit instructions have a direct mapping to a 32 bit instruction. Thus,
we convert the arguments in the 16 bit trans_ function to the arguments of
the corresponding 32 bit instruction and call the 32 bit trans_ function.
3) Remove old manual decoding in gen_* function [Patch 19-29]:
this move all manual translation code into the trans_* instructions of
decode tree, such that we can remove the old decode_* functions.
Palmer: This, with some additional cleanup patches, passed Alistar's
testing on rv32 and rv64 as well as my testing on rv64, so I think it's
good to go. I've run my standard test against this exact tag.
I still don't have a Mac to try this on, sorry!

The slirp code is not yet split off into a separate repository, so
configuring QEMU to use slirp as a submodule is premature. This
causes the non-existant "slirp" to be requested from git when syncing
submodules. This in turn appears to be cause of non-deterministic
failures some developers are seeing with QEMU's submodule sync process.

Commit dd577a26ff ("block/file-posix:
implement bdrv_co_invalidate_cache() on Linux") introduced page cache
invalidation so that cache.direct=off live migration is safe on Linux.
The invalidation takes a significant amount of time when the file is
large and present in the page cache. Normally this is not the case for
cross-host live migration but it can happen when migrating between QEMU
processes on the same host.
On same-host migration we don't need to invalidate pages for correctness
anyway, so an option to skip page cache invalidation is useful. I
investigated optimizing invalidation and detecting same-host migration,
but both are hard to achieve so a user-visible option will suffice.
As a bonus this option means that the cache invalidation feature will
now be detectable by libvirt via QMP schema introspection.

is used to translate multiply instructions.

this splits the 64-bit only instructions into its own decode file such
that we generate the decoder for these instructions only for the RISC-V
64 bit target.

for now only LUI & AUIPC are decoded and translated. If decodetree fails, we
fall back to the old decoder.
