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

   linux-user: Add missing signals in strace output

Series applied to my linux-user-for-7.2 branch,
except PATCH 11 and 12 that have comments.

Thank you !!
I'll send updated versions for patches 11 and 12 asap.
Btw, where can I find your linux-user-for-7.2 branch?
It would help me to diff the new patches against this branch...
