[PATCH v3 0/4] um: Add seccomp support

[MickaÃl SalaÃn]

This series add seccomp support to User-mode Linux (i386 and x86_64
subarchitectures) and fix ptrace issues. This apply on v4.4-rc7 and pass all
the 48 tests from selftest/seccomp plus the UML ptsc test.

Changes since v2:
* remove get_syscall() from os.h and don't include it in syscall.c [1/4]
* rebase to v4.4-rc7

Changes since v1; addressed Richard Weinberger's comments:
* fix a new PTRACE_SETREGS bug on x86_64 [1/4]
* fix an old PTRACE_SETREGS bug when updating orig_ax on i386 [1/4]

Regards,
 MickaÃl
