e20122ff0f checkpatch: handle token pasting better
The mechanism to find possible type tokens can sometimes be confused and go into an
infinite loop.  This happens for example in QEMU for a line that looks like

         uint## BITS ##_t S = _S, T = _T;                            \
         uint## BITS ##_t as, at, xs, xt, xd;                        \

Because the token pasting operator does not have a space before _t, it does not
match $notPermitted.  However, (?x) is turned on in the regular expression for
modifiers, and thus ##_t matches the empty string.  As a result, annotate_values
goes in an infinite loop.

The solution is simply to remove token pasting operators from the string before
looking for modifiers.  In the example above, the string uintBITS_t will be
evaluated as a candidate modifier.  This is not optimal, but it works as long
as people do not write things like a##s##m, and it fits nicely into sub
possible.

For a similar reason, \# should be rejected always, even if it is not
at end of line or followed by whitespace.

The same patch was sent to the Linux kernel mailing list.

81e34930ce qemu-char: check errno together with ret < 0
In the tcp_chr_write function, we checked errno,
but errno was not reset before a read or write operation.
Therefore, this check of errno's actions is often
incorrect after EAGAIN has occurred.
we need check errno together with ret < 0.

02693cc4f4 i386: fix '-cpu ?' output for host cpu type
Since commit d6dcc5583e, '-cpu ?' shows the description of the
X86_CPU_TYPE_NAME("max") for the host CPU model:

Enables all features supported by the accelerator in the current host

instead of the expected:

KVM processor with all supported host features

or

HVF processor with all supported host features

This is caused by the early use of kvm_enabled() and hvf_enabled() in
a class_init function. Since the accelerator isn't configured yet, both
helpers return false unconditionally.

A QEMU binary will only be compiled with one of these accelerators, not
both. The appropriate description can thus be decided at build time.

2729d79d49 pr-helper: Rework socket path handling
When reviewing Paolo's pr-helper patches I've noticed couple of
problems:

1) socket_path needs to be calculated at two different places
(one for printing out help, the other if socket activation is NOT
used),

2) even though the default socket_path is allocated in
compute_default_paths() it is the only default path the function
handles. For instance, pidfile is allocated outside of this
function. And yet again, at different places than 1)

ee8c13b814 pr-helper: avoid error on PR IN command with zero request size
After reading a PR IN command with zero request size in prh_read_request,
the resp->result field will be uninitialized and the resp.sz field will
be also uninitialized when returning to prh_co_entry.

If resp->result == GOOD (from a previous successful reply or just luck),
then the assert in prh_write_response might not be triggered and
uninitialized response will be sent.

The fix is to remove the whole handling of sz == 0 in prh_co_entry.
Those errors apply only to PR OUT commands and it's perfectly okay to
catch them later in do_pr_out and multipath_pr_out; the check for
too-short parameters in fact doesn't apply in the easy SG_IO case, as
it can be left to the target firmware even.

The result is that prh_read_request does not fail requests anymore and
prh_co_entry becomes simpler.

a428594042 RISC-V: SoCify SiFive boards and connect GEM
This series has three tasks:
  1. To convert the SiFive U and E machines into SoCs and boards
  2. To connect the Cadence GEM device to the SiFive U board
  3. Fix some device tree problems with the SiFive U board
 
 After this series the SiFive E and U boards have their SoCs split into
 seperate QEMU objects, which can be used on future boards if desired.
 
 The RISC-V Virt and Spike boards have not been converted. They haven't
 been converted as they aren't physical boards, so it doesn't make a
 whole lot of sense to split them into an SoC and board. The only
 disadvantage with this is that they now differ to the SiFive boards.
 
 This series also connect the Cadence GEM device to the SiFive U board.
 There are some interrupt line changes requried before this is possible.

19c9a18f45 docker: add linux-user powered cross builder for QEMU
We can't use cross compilers in the current Debian stable and Debian
sid is sketchy as hell. So for powerpc fall back to dog-fooding our
own linux-user to do the build.

As we can only build the base image with a suitably configured
source tree we fall back to checking for its existence when we can't
build it from scratch. However this does mean you don't have to keep
a static powerpc-linux-user in your active configuration just to
update the cross build image.

We might as well have a custom rule for this. For one thing the
dependencies are different. As the primary dependency for
docker-image-% could never be docker-image-debian-bootstrap we can
drop that test in the main rule as well.

Missing EXECUTABLE, DEB_ARCH and DEB_TYPE are treated as hard faults
now. We also error out if the EXECUTABLE file isn't there. We should
really do this with a dependency on any source rules but currently
subdir-FOO-linux-user isn't enough on a clean build.

547cb45ea3 docker: add special handling for FROM:debian-%-user targets
These will have been build with debootstrap so we need to check
against the debian-bootstrap dockerfile. This does mean sticking to
debian-FOO-user as the naming conventions for boot-strapped images.
The actual cross image is built on top.

300cf467fd docker: debian-bootstrap.pre allow customising of variant/url
We default to the buildd variant as most of our images are for
building. However lets give the user the ability to specify "minbase"
if they want to create a simple base image for experimentation.

Allowing the tweaking of DEB_URL means we can also bootstrap other
Debian based OS's. For example:

  make docker-binfmt-image-debian-ubuntu-bionic-arm64 \
       DEB_ARCH=arm64 DEB_TYPE=bionic \
       DEB_VARIANT=minbase DEB_URL=http://ports.ubuntu.com/ \
       EXECUTABLE=./aarch64-linux-user/qemu-aarch64

beac6a98f6 docker: ubuntu: Update the package list before installing new ones
Since docker caches the different layers, updating the package
list does not invalidate the previous "apt-get update" layer,
and it is likely "apt-get install" hits an outdated repository.

See https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get

This fixes:

7781afb49c linux-user: add gcov support to preexit_cleanup
As we don't always take the normal exit path when running a guest we
can skip the normal exit destructors where gcov normally dumps it's
info. The GCC manual suggests long running programs use __gcov_dump()
to flush out the coverage state periodically so we use that here.

0708e6476f travis: add gcovr summary for GCOV build
This gives a more useful summary, sorted by descending % coverage,
after the tests have run. The final numbers will give an idea if our
coverage is getting better or worse.

To keep the width sane we need to post process the file that the old
gcovr tool generates. This is done with a mix of sed, awk and column
in the scripts/coverage-summary.sh script.

As quite a lot of lines don't get covered at all we filter out all the
0% lines. If the file doesn't appear it is not being exercised.

7c20c808a5 file-posix: Unlock FD after creation
Closing the FD does not necessarily mean that it is unlocked.  Fix this
by relinquishing all permission locks before qemu_close().

d815efcaf0 file-posix: Fix creation locking
raw_apply_lock_bytes() takes a bit mask of "permissions that are NOT
shared".

Also, make the "perm" and "shared" variables uint64_t, because I do not
particularly like using ~ on signed integers (and other permission masks
are usually uint64_t, too).
