2020-07-13osdep.h: Always include <sys/signal.h> if it existsDavid CARLIER
Regularize our handling of <sys/signal.h>: currently we include it in osdep.h, but only for OpenBSD, and we include it without an ifdef guard in a couple of C files. This causes problems for Haiku, which doesn't have that header. Instead, check in configure whether sys/signal.h exists, and if it does then always include it from osdep.h.

2020-07-13build: Check that mlockall() existsDavid CARLIER
Instead of assuming that all POSIX platforms provide mlockall(), test for it in configure. If the host doesn't provide this platform then os_mlock() will fail -ENOSYS, as it does already on Windows. This is necessary for Haiku, which does not have mlockall().

2020-07-13util/qemu-openpty.c: Don't assume pty.h is glibc-onlyDavid CARLIER
Instead of using an OS-specific ifdef test to select the "openpty() is in pty.h" codepath, make configure check for the existence of the header and use the new CONFIG_PTY instead. This is necessary to build on Haiku, which also provides openpty() via pty.h.

2020-07-13target/arm: Don't do raw writes for PMINTENCLRAaron Lindsay
Raw writes to this register when in KVM mode can cause interrupts to be raised (even when the PMU is disabled). Because the underlying state is already aliased to PMINTENSET (which already provides raw write functions), we can safely disable raw accesses to PMINTENCLR entirely.

While at it, I also shortened the lines of the first example a little bit. Otherwise they showed up with a horizontal scrollbar in my Firefox browser.

2020-07-13GitLab Gating CI: introduce pipeline-status contrib scriptCleber Rosa
This script is intended to be used right after a push to a branch. By default, it will look for the pipeline associated with the commit that is the HEAD of the *local* staging branch. It can be used as a one time check, or with the `--wait` option to wait until the pipeline completes. If the pipeline is successful, then a merge of the staging branch into the master branch should be the next step.

2020-07-11Revert "vga: build virtio-gpu as module"Gerd Hoffmann
This reverts commit 8d5a24c83dba90b08ef163bbf166d6dfbad9019b. Compiling all virtio-gpu objects into a single module isn't a good plan because the individual objects have different CONFIG_* dependencies. Leads to module load failures on s390x due to vga support being disabled, which in turn breaks '-device virtio-gpu-device' (flagged by travis ci). So back to the drawing board for modular virtio-gpu ...

2020-07-11tests/qht-bench: Adjust threshold computationRichard Henderson
In 06c4cc3660b3, we split the multiplication in two parts to avoid a clang warning. But because double still rounds to 53 bits, this does not provide additional precision beyond multiplication by nextafter(0x1p64, 0), the largest representable value smaller than 2**64. However, since we have eliminated 1.0, mutiplying by 2**64 produces a better distribution of input values to the output values.

2020-07-11tests: improve performance of device-introspect-testDaniel P. Berrangé
Total execution time with "-m slow" and x86_64 QEMU, drops from 3 minutes 15 seconds, down to 54 seconds. Individual tests drop from 17-20 seconds, down to 3-4 seconds. The cost of this change is that any QOM bugs resulting in the test failure will not be directly associated with the device that caused the failure. The test case is not frequently identifying such bugs though, and the cause is likely easily visible in the patch series that causes the failure. So overall the shorter running time is considered the more important factor. Signed-off-by: Daniel P.
