f02f4e8406 Fixed a bug that previous revision has introduced -- we missed
the double quotes ("" and '') as a separate argument.

Reported by:	ache

The fix in this and previous revisions combined is functionally
equivalent to the below patch against rev. 1.27 but the code is
now much easier to follow:

67b460e517 Dhclient dumps core on suspend/resume cycles. If the client isn't active
then we need to go to the reboot state or in state_bound it will core on
the de-reference of client -> active -> options since client -> active = NULL.

While we are here, fix the indentation.

f7071e6735 - Now that both schedulers support temporary cpu pinning use this rather
than the switchin functions to guarantee that we're operating with the
   correct tlb entry.
 - Remove the post copy/zero tlb invalidations.  It is faster to invalidate
   an entry that is known to exist and so it is faster to invalidate after
   use.  However, some architectures implement speculative page table
   prefetching so we can not be guaranteed that the invalidated entry is still
   invalid when we re-enter any of these functions.  As a result of this we
   must always invalidate before use to be safe.

539782b88b - Don't define DETECT_DEADLOCK. I don't know that this code has detected
a deadlock in several years.  Furthermore, the IPI code is currently
   protected by a seperate spinlock.  This only served to make IPIs twice as
   expensive as they had to be which severely slowed down the IPI heavy ULE
   scheduler.

c85cdc3d0f - Add a flags parameter to mi_switch. The value of flags may be SW_VOL or
SW_INVOL.  Assert that one of these is set in mi_switch() and propery
   adjust the rusage statistics.  This is to simplify the large number of
   users of this interface which were previously all required to adjust the
   proper counter prior to calling mi_switch().  This also facilitates more
   switch and locking optimizations.
 - Change all callers of mi_switch() to pass the appropriate paramter and
   remove direct references to the process statistics.

ca8a19313e Add some basic support for measuring sleep mutex contention to the
mutex profiling code.  As with existing mutex profiling, measurement
is done with respect to mtx_lock() instances in the code, as opposed
to specific mutexes.  In particular, measure two things:

(1) Lock contention.  How often did this mtx_lock() call get made and
    have to sleep (or almost sleep) waiting for the lock.  This helps
    identify the "victims" of contention.

(2) Hold contention.  How often, while the lock was held by a thread
    as a result of this mtx_lock(), did another thread try to acquire
    the same mutex.  This helps identify the causes of contention.

I'm currently exploring adding measurement of "time waited for the
lock", but the current implementation has proven useful to me so far
so I figured I'd commit it so others could try it out.  Note that this
increases the size of mutexes when MUTEX_PROFILING is enabled, so you
might find you need to further bump UMA_BOOT_PAGES.  Fixes welcome.

81a3e3bfb9 Deal with MOD_FREQUENCY before MOD_OFFSET because the latter is the
one which runs the actual update.  This fixes a bug where there were
a delay in applying the frequency adjustment.  In extreme cases this
could result in marginal stability of the kernel-pll.

60b2122af9 1. Statically initialize swap_pager_full and swap_pager_almost_full to the
full state.  (When swap is added their state will change appropriately.)
2. Set swap_pager_full and swap_pager_almost_full to the full state when
   the last swap device is removed.
Combined these changes eliminate nonsense messages from the kernel on swap-
less machines.
