as well as support mmap(2) flag MAP_DROPPABLE to allow
zero memory under memory pressure on newer Linux systems.

Otherwise a `make -k check` fails here in our build environment
with newer kernels and with /dev/console as physical device.

Shouldn't this be 0x08? At least that's how it's defined in mman.h.

If the kernel does not know (means header does not know) we should not
set an unknown flags as this will fail also (IMHO).
Only if older header files are used in combination with newer kernel
we would see the current behaviour.

The code in question doesn't actually call mmap, it creates a syscall filter that tests whether any unknown flags are set.  Basically
  if ((flags & ~known_flags) != 0) abort();
So putting something into known_flags that might not be known to the kernel when Emacs is run is harmless.  In fact, it's beneficial for the case where the mman.h that's used when compiling seccomp-filter.c is older than the kernel that will be used to run Emacs.

Nit pick could you link to kernel.org instead?

The replacement link would be:
https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9651fcedf7b92d3f7f1ab179e8ab55b85ee10fc1

What is about the attacheds patch ... here I go with the
latest manual page ioctl_tty(2) as well if the macro
MAP_DROPPABLE is not defined then the value 0x08 is
used.
