* remotes/bonzini-gitlab/tags/for-upstream:
meson: reenable filemonitor-inotify compilation
meson: build all modules by default
configure: do not create roms/seabios/config.mak if SeaBIOS not present
tests/tcg: Fix target-specific Makefile variables path for user-mode
KVM: x86: ignore interrupt_bitmap field of KVM_GET/SET_SREGS
KVM: use KVM_{GET|SET}_SREGS2 when supported.
meson: add comments in the target-specific flags section
configure, meson: move config-poison.h to meson
meson: build contrib/ executables after generated headers
configure: move non-command-line variables away from command-line parsing section
configure: parse --enable/--disable-strip automatically, flip default
configure, makefile: remove traces of really old files
configure: do not set bsd_user/linux_user early
configure: simplify creation of plugin symbol list
block/file-posix: Simplify the XFS_IOC_DIOINFO handling
meson: cleanup common-user/ build
user: move common-user includes to a subdirectory of {bsd,linux}-user/
