Now that the script 'features-refresh.sh' is available, uses this script
to refresh all the arch-support.txt files in place.

Arnd Bergmann 1ea5afd42a Documentation: arch-support: remove obsolete architectures
A number of architecture ports are obsolete and getting dropped,
so we no longer want to track the respective features.

We already removed the lines for metag and mn10300, this does
the same edits for all the others.

For the remaining 21 architectures, this shows how many are known
to implement each given feature:

need to be added.

The AVR32 architecture support has been removed from the Linux kernel,
hence remove all references to it from Documentation.

Mickaël Salaün c50b4659e4 um: Add seccomp support
This brings SECCOMP_MODE_STRICT and SECCOMP_MODE_FILTER support through
prctl(2) and seccomp(2) to User-mode Linux for i386 and x86_64
subarchitectures.

secure_computing() is called first in handle_syscall() so that the
syscall emulation will be aborted quickly if matching a seccomp rule.

This is inspired from Meredydd Luff's patch
(https://gerrit.chromium.org/gerrit/21425).
