[PATCH v3 00/12] linux-user: Add more syscalls, enhance tracing & logging enhancements

[Helge Deller]

Here is a bunch of patches for linux-user.

Most of them add missing syscalls and enhance the tracing/logging.
Some of the patches are target-hppa specific.
I've tested those on productive hppa debian buildd servers (running qemu-user).

Thanks!
Helge

Changes to v2:
- Fix build of close_range() and pidfd_*() patches on older Linux
  distributions (noticed by Stefan Hajnoczi)

Changes to v1:
- Dropped the faccessat2() syscall patch in favour of Richard's patch
- Various changes to the "missing signals in strace output" patch based on
  Richard's feedback, e.g. static arrays, fixed usage of _NSIG, fix build when
  TARGET_SIGIOT does not exist
- Use FUTEX_CMD_MASK in "Show timespec on strace for futex" patch
  unconditionally and turn into a switch statement - as suggested by Richard
