225edeac51 - When there is no room for returning the result, nss backend
have to return ERANGE and terminate with NS_RETURN.
- When gethostbyname_r(3) and the friends end with an error,
  set errno to the value nss backend returns, and return errno
  value.

5ef8fb65f9 Allow interrupt driven config hooks to be registered from config hook callbacks.
Interrupt driven configuration hooks serve two purposes: they are a
mechanism for registering for a callback that is invoked once interrupt
services are available, and they hold off root device selection so long
as any configuration hooks are still active.  Before this change, it was
not possible to safely register additional hooks from the context of a
configuration hook callback.  The need for this feature arises when
interrupts are required to discover new devices (e.g. access to the XenStore
to find para-virtualized devices) which in turn also require the ability
to hold off root device selection until some lengthy, interrupt driven,
configuration task has completed (e.g. Xen front/back device driver
negotiation).

More specifically, the mutex protecting the list of active configuration
hooks is never held during a callback, and static information is used
to ensure proper ordering and only a single callback to each hook even
when faced with registration or removal of a hook during an active run.

116a77bda7 Add the half of time-of-day clock resolution when we adjust system time from
time-of-day clock or vice versa.  For x86 systems, RTC resolution is one
second and we used to lose up to one second whenever we initialize system
time from RTC or write system time back to RTC.  With this change, margin
of error per conversion is roughly between -0.5 and +0.5 second rather
than between -1 and 0 second.  Note that it does not take care of errors
from getnanotime(9) (which is up to 1/hz second) or CLOCK_GETTIME() latency.
These are just too expensive to correct and it is not worthy of the cost.

User created symbolic links are now inserted at the head of the
directory entry list after the "." and ".." entries. A new directory
entry flag DE_COVERED indicates that an entry is covered by a symbolic
link.

2c4575477e Fix crunchide to work on sparc64 and perhaps other 64 bit platforms.
I used the wrong type when setting st_name in the symbol table entry
struct. It's an Elf64_Word which is defined as an unsigned 32 bit int
on both 32 and 64 bit platforms.

To make things sensible, define some new macros to use as "word" macros
and use those, rather than simply using the explicit 32 bit macros.

619fede20e Implement pmap changes suggested by alc@:
1. Move dirty bit emulation code that is duplicted for kernel and user
in trap.c to a function pmap_emulate_modified() in pmap.c.

2. While doing dirty bit emulation, it is not necessary to update the
TLB entry on all CPUs using smp_rendezvous(), we can just update the
TLB entry on the current CPU, and let the other CPUs update their TLB
entry lazily if they get an exception.

3beb1b723f The buffers b_vflags field is not always properly protected by
bufobj lock. If b_bufobj is not NULL, then bufobj lock should be
held when manipulating the flags. Not doing this sometimes leaves
BV_BKGRDINPROG to be erronously set, causing softdep' getdirtybuf() to
stuck indefinitely in "getbuf" sleep, waiting for background write to
finish which is not actually performed.

Add BO_LOCK() in the cases where it was missed.

691401eef8 Softdep_process_worklist() should unsuspend not only before processing
the worklist (in softdep_process_journal), but also after flushing the
workitems. Might be, we should even do this before bwillwrite() too, but
this seems to be not needed for now.

Fs might be suspended during processing the queue, and then there is
nobody around to unsuspend.

52f81b679a Loading the NF CCA values may take longer than expected to occur.
If it does, don't then try reprogramming the NF "cap" values (ie
what values are the "maximum" value the NF can be) - instead,
just leave the current CCA value as the NF cap.

This was inspired by some similar work from ath9k. It isn't
a 100% complete solution (as there may be some reason where a
high NF CCA/cap is written, causing the baseband to stop thinking it
is able to transmit, leading to stuck beacon and interface reset)
which I'll investigate and look at fixing in a later commit.

422605a3b9 - Improve the wait4data() routine so it behaves better when checking
print-jobs which have last-modification times that are in the future.
  This shouldn't happen, of course, but it can.  And when it did happen,
  the previous check could cause completely-spooled jobs to sit in the
  queue for 20 minutes per job.  The new code waits until the last-modify
  time is not changing, instead of making decisions based on the specific
  value of last-modify.
