Log:
  For 6000 series and newer devices the DC calibration results are no
  longer requested of the boot firmware. Instead of sending those results
  to the runtime firmware the firmware is told to do the DC calibration
  itself.

Log:
 Remove gratuitous i386/amd64 inconsistency in favour of the less verbose
 version of declaring a variable initialized to zero.


This is resolved backwardsly.  style(9) forbids initializing variables in
declarations (except for the bug in it which allows this).

Also, here this is inconsisent with all the other initializations, since
those actually follow style(9).

Other style bugs visible in this patch:
- the declarations are totally disordered.  The initializations are at least
  in the same order as the declarations
- the cast in the old initialization of `lastaddr' was followed by a space.
  It is unclear if this cast is needed, and the new initialization doesn't
  have it.  It is not needed if bus_addr_t is a integer or pointer type,
  but bus_addr_t should be opaque.  If it is a pointer type, then the variable
  is not initialized to zero, but to a null pointer.  MD code like this can
  know what it is, but then you can't copy this code around.

Some of the other functions in this file have larger style bugs in
declarations/initializations than this.

Log:
  Bring in a new feature, adding a -f option to readlink to print the path
  of the target, similar to realpath(1). See the discussion at:
  http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=34662

  grok -f, and there's no alternative (+fix)

  1.27
  "The ofmt variable is actually a bit mask (not the character that was
  in the format string) so that we can "or" it with the bits in the
  formats variable.  This fixes the missing " -> " in front of the real
  path (when you use %SR).
  
  Also, the ?: needs another space."
  
  Obtained from:ata...@netbsd.org
  
  I am purposely omitting the following changes:

svn commit: r216205 - head/usr.bin/stat

2010-12-05 Thread Doug Barton 
Author: dougb
Date: Sun Dec  5 21:29:20 2010
New Revision: 216205
URL: http://svn.freebsd.org/changeset/base/216205

Log:
  Bring in the update from NetBSD 1.28:
  
  "Fix WARNS=4 issues (-Wcast-qual -Wsign-compare)"
  
  Because of code differences I had to hand-apply parts of the patch,
  so responsibility for errors goes to me.

Log:
  sh: Avoid marking a job as done before it is fully created.
  
  In r208489, I added code to reap zombies when forking new processes, to
  limit the amount of zombies. However, this can lead to marking a job as done
  or stopped if it consists of multiple processes and the first process ends
  very quickly. Fix this by only checking for zombies before forking the first
  process of a job and not marking any jobs without processes as done or
  stopped.

svn commit: r216210 - head/lib/msun/src

2010-12-05 Thread David Schultz 
Author: das
Date: Sun Dec  5 22:11:03 2010
New Revision: 216210
URL: http://svn.freebsd.org/changeset/base/216210

Log:
  Add a "kernel" log function, based on e_log.c, which is useful for
  implementing accurate logarithms in different bases.  This is based
  on an approach bde coded up years ago.
  
  This function should always be inlined; it will be used in only a few
  places, and rudimentary tests show a 40% performance improvement in
  implementations of log2() and log10() on amd64.
  
  The kernel takes a reduced argument x and returns the same polynomial
  approximation as e_log.c, but omitting the low-order term. The low-order
  term is much larger than the rest of the approximation, so the caller of
  the kernel function can scale it to the appropriate base in extra precision
  and obtain a much more accurate answer than by using log(x)/log(b).

Log:
  sh: Improve jobs output of pipelines.
  
  If describing the status of a pipeline, write all elements of the pipeline
  and show the status of the last process (which would also end up in $?).
  Only write one report per job, not one for every process that exits.
  
  To keep some earlier behaviour, if any process started by the shell in a
  foreground job terminates because of a signal, write a message about the
  signal (at most one message per job, however).
  
  Also, do not write messages about signals in the wait builtin in
  non-interactive shells. Only true foreground jobs now write such messages
  (for example, "Terminated").
