[PATCH 0/2] doc: LSM: update usage document for current LSM stacking

The LSM usage document (Documentation/admin-guide/LSM/index.rst) has
not kept up with the LSM stacking infrastructure. It still describes
CONFIG_DEFAULT_SECURITY, which no longer exists, and its description
of the module ordering in /sys/kernel/security/lsm does not match
what the framework actually does.

Patch 1 updates the selection mechanism description to CONFIG_LSM and
the "lsm=" parameter, keeping "security=" documented as the deprecated
legacy option. This revisits an earlier attempt by Randy Dunlap [1]
that was rejected for treating the two parameters as equivalent; the
new text keeps them distinct.

Patch 2 fixes the ordering description: lockdown precedes capability
when CONFIG_SECURITY_LOCKDOWN_LSM_EARLY is enabled, the integrity
modules are always placed at the end of the list, and the remaining
modules follow the order given by CONFIG_LSM or "lsm=".
