0297e0c067 Handle unlikely errors from personality syscall 
Despite being marked as SYSCALL_NEVER_FAILS, personality syscall still
might report a failure on some architectures due to obscure kernel
bugs.  Check for this unlikely case and let users know that their
kernel has gone bananas.

* personality.c (SYS_FUNC(personality)): Do not parse syscall return
value in case of syserror.

727508b077 Enhance personality syscall decoding 
* xlat/personality_options.in: Split into ...
* xlat/personality_types.in: ... personality types and ...
* xlat/personality_flags.in: ... personality flags.
* personality.c: Include "xlat/personality_types.h"
and "xlat/personality_flags.h" instead of "xlat/personality_options.h".
(SYS_FUNC(personality)): Print PER_MASK part of personality as
a symbolic value, and the rest of personality as a set of flags.
* tests/personality.c (main): Add more test cases.
* tests/personality.test: Update.

1e155f76e7 Print personality value 0xffffffff properly 
Value 0xffffffff of personality syscall first argument has a special
meaning, it is not a set of personality flags.

* personality.c (SYS_FUNC(personality)): If personality equals
to 0xffffffff, print it verbatim.
* tests/personality.c (main): Test it.
