when allocating the record in the first place, allocate the final buffer
when closing the BSM record. At that point, more size information is
available, so a sufficiently large buffer can be allocated.
This allows the kernel to generate audit records in excess of
MAXAUDITDATA bytes, but is consistent with Solaris's behavior. This only
comes up when auditing command line arguments, in which case we presume
the administrator really does want the data as they have specified the
policy flag to gather them.

is incorrect, and causes endianness bugs on 64-bit big-endian
machines (sparc64), it's the best choice for now, as many of
these IOCTLs are used inside the kernel, and bogusly pass an
argument as "int *" which results in unaligned access panics
on sparc64 when attempting to dereference them via *(intptr_t *).
(Several of us are working on a real fix, which is uneasy.)
switch by worklist type contains two for() loops, for D_INDIRDEP and
D_PAGEDEP. On error, these loops are exited by break, where the switch
actually shall be leaved. Use goto instead of break to reach the error
handling code.

code is still under giant lock, but the session/pgrp release code just used
proctree_locks. This explains why moving the proctree_lock in sys/kern/tty.c
rev. 1.258 did fix the panics in our SMP systems.
This should also fix some race panics with revoked ttys.
