Meson runs a test to see if Sphinx works, and automatically disables it
on error. This can lead to the CI jobs skipping docs build without
maintainers noticing the problem. Use --enable-docs to force a fatal
error if Sphinx doesn't work on the jobs where we expect it to be OK.

Most of the build jobs will create the sphinx documentation. If we
expose this as an artifact of a "pages" job in a "public" directory, it
will get published using GitLab Pages. This means a user can push a
branch with docs changes to GitLab and view the results at
https://yourusername.gitlab.io/qemu/

LLVM's linker, LLD, supports the keyword "INSERT AFTER", starting with
version 11.
However, when multiple sections are defined in the same "INSERT AFTER",
they are added in a reversed order, compared to BFD's LD.
This patch makes fork_fuzz.ld generic enough to work with both linkers.
Each section now has its own "INSERT AFTER" keyword, so proper ordering is
defined between the sections added.

We switched to hardlinks in
a942f64cc4 ("scripts/oss-fuzz: use hardlinks instead of copying")
The motivation was to conserve space (50 fuzzers built with ASAN, can
weigh close to 9 GB).
Unfortunately, OSS-Fuzz (partially) treated the underlying copy of the
fuzzer as a standalone fuzzer. To attempt to fix, we tried:
f8b8f37463 ("scripts/oss-fuzz: rename bin/qemu-fuzz-i386")
This was also not a complete fix, because though OSS-Fuzz
ignores the renamed fuzzer, the underlying ClusterFuzz, doesn't:
https://storage.googleapis.com/clusterfuzz-builds/qemu/targets.list.address
https://oss-fuzz-build-logs.storage.googleapis.com/log-9bfb55f9-1c20-4aa6-a49c-ede12864eeb2.txt
(clusterfuzz still lists qemu-fuzz-i386.base as a fuzzer)
This change keeps the hard-links, but makes them all point to a file
with a qemu-fuzz-i386-target-.. name. If we have targets, A, B, C, the
result will be:
qemu-fuzz-i386-target-A (base file)
qemu-fuzz-i386-target-B -> qemu-fuzz-i386-target-A
qemu-fuzz-i386-target-C -> qemu-fuzz-i386-target-A
The result should be that every file that looks like a fuzzer to
OSS-Fuzz/ClusterFuzz, can run as a fuzzer (we don't have a separate base
copy). Unfortunately, there is not simple way to test this locally.
In the future, it might be worth it to link the majority of QEMU in as a
shared-object (see https://github.com/google/oss-fuzz/issues/4575 )

The 'addr' would not be NULL after checking 'succ' is valid,
and it has been dereferenced in the previous code(args = g_strdup_printf()).
So the check on 'addr' in the tpm_test_swtpm_test() is redundant. Remove it.

After the transition to Meson, the build directory now have
subdirectories named "qemu-system-*.p", and device-crash-test
will try to execute them as if they were binaries. This results
in errors like:
PermissionError: [Errno 13] Permission denied: './qemu-system-or1k.p'
When generating the default list of binaries to test, check if
the path is actually a file and if it's executable.

libvhost-user is needed when CONFIG_LINUX is set. The CONFIG_VHOST_USER
check in meson.build is incorrect.
In fact, no explicit check is needed since this dependency is not built
by default. If something declares a dependency on libvhost-user then it
will be built, otherwise it won't be built (i.e. on non-Linux hosts).
This fixes ./configure --disable-vhost-user && make.

BlockDeviceMapEntry has never been used. It was added in commit
facd6e2 "so that it is published through the introspection mechanism."
What exactly introspecting types that aren't used for anything could
accomplish isn't clear. What "introspection mechanism" to use is also
nebulous. To the best of my knowledge, there has never been one that
covered this type. Certainly not query-qmp-schema, which includes
only types that are actually used in QMP.
Not being able to introspect BlockDeviceMapEntry hasn't bothered
anyone enough to complain in almost four years. Get rid of it.

MapEntry and BlockDeviceMapEntry are kind of the same thing, and the
latter is not used, so we want to remove it. However, the documentation
it provides for some fields is better than that of MapEntry, so steal
some of it for the latter.
(And adjust them a bit in the process, because I feel like we can make
them even clearer.)

To be fair with other subsystems listed as 'Odd Fixes' but having
maintainers more present, demote the Renesas sections from being
'Maintained' to 'Odd Fixes' (has a maintainer but they don't have
time to do much other than throw the odd patch in.)
This matches Magnus's possibilities so far:

The nanoMIPS ISA has been announced in 2018 for various projects:
GCC: https://gcc.gnu.org/legacy-ml/gcc/2018-05/msg00012.html
Linux: https://lwn.net/Articles/753605/
QEMU: https://www.mail-archive.com/qemu-devel@nongnu.org/msg530721.html
Unfortunately the links referenced doesn't work anymore (www.mips.com).
From this Wayback machine link [1] we can get to a working place to
download a toolchain (a more recent release than the one referenced
in the announcement mails):
http://codescape.mips.com/components/toolchain/nanomips/2018.04-02/downloads.html
The toolchain page mention LLVM but simply links http://llvm.org/
where there is no reference on nanoMIPS.
The only reference in the GCC mailing list, is the nanoMIPS
announcement: https://gcc.gnu.org/pipermail/gcc/2018-May.txt
The developer who authored the announcements have been emailed [2]
to ask for more information but all their emails are now bouncing:
- Your message to Stefan.Markovic@mips.com couldn't be delivered.
- Your message to smarkovic@wavecomp.com couldn't be delivered.
- Couldn't deliver the message to the following recipients:
Robert.Suchanek@mips.com, matthew.fortune@mips.com,
marcin.nowakowski@mips.com
Our deprecation policy do not allow feature removal before 2 release,
therefore declare the nanoMIPS ISA code deprecated as of QEMU 5.2.
This gives time to developers to update the QEMU community, or
interested parties to step in to maintain this code.

s390-pci-vfio.c calls into the vfio code, so we need it to be
built conditionally on vfio (which implies CONFIG_LINUX).

This patch adds some gen_io_start() calls to allow execution
of s390x targets in icount mode with -smp 1.
It enables deterministic timers and record/replay features.

The architecture states that the iplb location is only written to low
core for list directed ipl and not for traditional ccw ipl. If we don't
skip this then operating systems that load by reading into low core
memory may fail to start.
We should also not write the iplb pointer for network boot as it might
overwrite content that we got via network.

Commit b2c00bce54c ("meson: convert hw/9pfs, cleanup") introduced
CONFIG_9PFS (probably a wrong conflict resolution). This config is
not used anywhere. Backends depend on CONFIG_FSDEV_9P which itself
depends on CONFIG_VIRTFS.
Remove the invalid CONFIG_9PFS and use CONFIG_FSDEV_9P instead, to
fix the './configure --without-default-devices --enable-xen' build:

Coverity points out that we don't check the return value from
copy_from_user() in vma_dump_size(). This is to some extent
a "can't happen" error since we've already checked the page
with an access_ok() call earlier, but it's simple enough to
handle the error anyway.

In pgd_find_hole_fallback(), Coverity doesn't like the use
of "if (MAP_FIXED_NOREPLACE || ...)" because it's using a
logical operator on a constant other than 0 or 1 and its
heuristic thinks we might have intended a bitwise operator
instead.
The logic is correct (we are checking whether the host really
has a MAP_FIXED_NOREPLACE or whether we fell back to the
"#define as 0 to ignore" from osdep.h); make Coverity
happier by explicitly writing out the comparison with zero.

HPT resizing is asynchronous: the guest first kicks off the creation of a
new HPT, then it waits for that new HPT to be actually created and finally
it asks the current HPT to be replaced by the new one.
In the case of a userland allocated HPT, this currently relies on calling
qemu_memalign() which aborts on OOM and never returns NULL. Since we seem
to have path to report the failure to the guest with an H_NO_MEM return
value, use qemu_try_memalign() instead of qemu_memalign().

Sometimes QEMU needs to allocate the HPT in userspace, namely with TCG
or PR KVM. This is performed with qemu_memalign() because of alignment
requirements. Like glib's allocators, its behaviour is to abort on OOM
instead of returning NULL.
This could be changed to qemu_try_memalign(), but in the specific case
of spapr_reallocate_hpt(), the outcome would be to terminate QEMU anyway
since no HPT means no MMU for the guest. Drop the dead code instead.

This reverts commit cd0372c515c4732d8bd3777cdd995c139c7ed7ea.
The patch is incorrect in that it retains copies between globals and
non-local temps, and non-local temps still die at the end of the BB.
Failing test case for hppa:
.globl _start
_start:
cmpiclr,= 0x24,%r19,%r0
cmpiclr,<> 0x2f,%r19,%r19
---- 00010057 0001005b
movi_i32 tmp0,$0x24
sub_i32 tmp1,tmp0,r19
mov_i32 tmp2,tmp0
mov_i32 tmp3,r19
movi_i32 tmp1,$0x0

movi_i32 tmp1,$0x0
mov_i32 r19,tmp1
setcond_i32 psw_n,tmp2,tmp3,ne
set_label $L1
In this case, both copies of "mov_i32 tmp3,r19" are removed. The
second because opt thought it was redundant. The first is removed
later by liveness because tmp3 is known to be dead. This leaves
the setcond_i32 with an uninitialized input.
Revert the entire patch for 5.2, and a proper optimization across
the branch may be considered for the next development cycle.

done later at the end of tcg_gen_code. There, a failing range
check results in a returned error code, which causes the TB to
be restarted at half the size.

pc,pci,vhost,virtio: fixes
