Subject: [PATCH 1/2 -mm] capabilities: define CONFIG_COMMONCAP
currently the compilation of commoncap.c is determined
through Makefile logic. So there is no single CONFIG
variable which can be relied upon to know whether it
will be compiled.
Define CONFIG_COMMONCAP to be true when lsm is not
compiled in, or when the capability or rootplug modules
are compiled. These are the cases when commoncap is
currently compiled. Use this variable in security/Makefile
to determine commoncap.c's compilation.
Apart from being a logic cleanup, this is needed by the
upcoming cap_bset patch so that prctl can know whether
PR_SET_BSET should be allowed.
