MFC r274286:

Pull in r201784 from upstream llvm trunk (by Benjamin Kramer):

  AsmParser: Disable Darwin-style macro argument expansion on non-darwin targets.

  There is code in the wild that relies on $0 not being expanded.

This fixes some cases of using $ signs in literals being incorrectly
assembled.

MFC r274294:

Add llvm patch corresponding to r274286.
MFC r272190:

cxgbe(4): explicitly set various if_hw_tso* values.
MFC r273280:

cxgb(4): reset the PHY if it generates an interrupt for no apparent reason.
MFC r273615:

cxgbe(4): bump up PF4's share of some global resources.

This increases the size of the per-port RSS slice and also allows the
driver to use a larger number of tx and rx queues.
MFC r273627,r273628:

r273627:

  - Print out "Bail out!" in die(..) so prove terminates immediately
  - Handle the output from newer versions of openssl md5, similar to what
    pjd@ did in r248304

r273628:

  Move the redirection to stderr out of the cmd variable assignment

  Putting 2>/dev/null in cmd= escapes the redirection operation, which causes
  mdconfig to think it's a filename

Release 2014j - 2014-11-10 17:37:11 -0800

  Changes affecting current and future time stamps

    Turks & Caicos' switch from US eastern time to UTC-4 year-round
    did not occur on 2014-11-02 at 02:00.  It's currently scheduled
    for 2015-11-01 at 02:00.  (Thanks to Chris Walton.)

  Changes affecting past time stamps

    Many pre-1989 time stamps have been corrected for Asia/Seoul and
    Asia/Pyongyang, based on sources for the Korean-language Wikipedia
    entry for time in Korea.  (Thanks to Sanghyuk Jung.)  Also, no
    longer guess that Pyongyang mimicked Seoul time after World War II,
    as this is politically implausible.

    Some more zones have been turned into links, when they differed
    from existing zones only for older time stamps.  As usual,
    these changes affect UTC offsets in pre-1970 time stamps only.
    Their old contents have been moved to the 'backzone' file.
    The affected zones are: Africa/Addis_Ababa, Africa/Asmara,
    Africa/Dar_es_Salaam, Africa/Djibouti, Africa/Kampala,
    Africa/Mogadishu, Indian/Antananarivo, Indian/Comoro, and
    Indian/Mayotte.

  Changes affecting commentary

    The commentary is less enthusiastic about Shanks as a source,
    and is more careful to distinguish UT from UTC.
