96ccbf68a6 Pull in r156591 from upstream llvm trunk: 
Allow unique_file to take a mode for file permissions, but default
  to user only read/write.

and r156592 from upstream clang trunk:

  For final output files create them with mode 0664 to match other
  compilers and expected defaults.

This should fix clang creating files with mode 0600.

6516bffdef Rename pmap_collect() to pmap_pv_reclaim() and rewrite it such that it no 
longer uses the active and inactive paging queues.  Instead, the pmap now
maintains an LRU-ordered list of pv entry pages, and pmap_pv_reclaim() uses
this list to select pv entries for reclamation.

Note: The old pmap_collect() tried to avoid reclaiming mappings for pages
that have either a hold_count or a busy field that is non-zero.  However,
this isn't necessary for correctness, and the locking in pmap_collect() was
insufficient to guarantee that such mappings weren't reclaimed.  The new
pmap_pv_reclaim() doesn't even try.

c414207ab0 Compute the master clock frequency, so we no longer need to have it 
compiled into the kernel.  This allows us to boot the same kernel on
machines with different master clock frequencies, so long as we can
determine the main clock frequency accurately.  Cleanup the pmc clock
init function so it can be called in early boot so we can use the
serial port just after we call cninit.

# We have two calls to at91_pmc_clock_init for reasons unknown, that will
# be fixed later -- it is harmless for now.

b10ed4a911 Replace all uses of the vm page queues lock by a r/w lock that is private 
to this pmap.c.  This new r/w lock is used primarily to synchronize access
to the TTE lists.  However, it will be used in a somewhat unconventional
way.  As finer-grained TTE list locking is added to each of the pmap
functions that acquire this r/w lock, its acquisition will be changed from
write to read, enabling concurrent execution of the pmap functions with
finer-grained locking.
