d3109e582d o Screw over users of the kern.{security.,}suser_permitted sysctl again,
by renaming it to kern.security.suser_enabled.  This makes the name
  consistent with other use: "permitted" now refers to a specific right
  or privilege, whereas "enabled" refers to a feature.  As this hasn't
  been MFC'd, and using this destroys a running system currently, I believe
  the user base of the sysctl will not be too unhappy.
o While I'm at it, un-staticize and export the supporting variable, as it
  will be used by kern_cap.c shortly.

08e732a88b Remove the MPSAFE keyword from the parser for syscalls.master.
Instead introduce the [M] prefix to existing keywords.  e.g.
MSTD is the MP SAFE version of STD.  This is prepatory for a
massive Giant lock pushdown.  The old MPSAFE keyword made
syscalls.master too messy.

Begin comments MP-Safe procedures with the comment:
/*
 * MPSAFE
 */
This comments means that the procedure may be called without
Giant held (The procedure itself may still need to obtain
Giant temporarily to do its thing).

sv_prepsyscall() is now MP SAFE and assumed to be MP SAFE
sv_transtrap() is now MP SAFE and assumed to be MP SAFE

ktrsyscall() and ktrsysret() are now MP SAFE (Giant Pushdown)
trapsignal() is now MP SAFE (Giant Pushdown)

Places which used to do the if (mtx_owned(&Giant)) mtx_unlock(&Giant)
test in syscall[2]() in */*/trap.c now do not.  Instead they
explicitly unlock Giant if they previously obtained it, and then
assert that it is no longer held to catch broken system calls.

Rebuild syscall tables.

4b437abe78 If a file has been completely unlinked, stop automatically syncing the
file.  ffs will discard any pending dirty pages when it is closed,
so we may as well not waste time trying to clean them.  This doesn't
stop other things from writing it out, eg: pageout, fsync(2) etc.

70aca15c21 Optionize UPAGES for the i386. As part of this I split some of the low
level implementation stuff out of machine/globaldata.h to avoid exposing
UPAGES to lots more places.  The end result is that we can double
the kernel stack size with 'options UPAGES=4' etc.

This is mainly being done for the benefit of a MFC to RELENG_4 at some
point.  -current doesn't really need this so much since each interrupt
runs on its own kstack.

12d4e47ee8 Force a commit on kern_mutex.c to explain reason for last commit but while
I'm at it also add a comment in mtx_validate() explaining the purpose
of the last change.

Basically, this fixes booting kernels compiled with MUTEX_DEBUG. What used
to happen is before we setidt from init386() [still using BTX idt], we
called mtx_init() on several mutex locks, notably Giant and some others.
This is a problem for MUTEX_DEBUG because it enables mtx_validate() which
calls kernacc(), some of which in turn requires Giant.
Fix by calling kernacc() from mtx_validate() only if (!cold).

1383792740 Add a new kernel option RESTARTABLE_PANICS. If this option is present,
then one can restart from a panic by resetting the panicstr variable to
NULL.  This commit conditionalizes the previously committed functionality
on this variable.  It also removes the __dead2 attribute from the panic()
function so that when one continues from a panic() the behavior will
be predictable.
