[patch 3/5] Apply the PG_sensitive flag to audit subsystem

["Larry H." <research@subreption.com>]

This patch deploys the use of the PG_sensitive page allocator flag
within the audit subsystem. It's not necessarily a high profile
target for use of this flag, but could be expected to contain
potentially sensitive information under some circumstances.
