svn commit: r333819 - in head/sys: conf modules/blake2 modules/crypto modules/drm2/i915kms modules/ipfilter

[Matt Macy]

Author: mmacy
Date: Sat May 19 00:04:01 2018
New Revision: 333819
URL: https://svnweb.freebsd.org/changeset/base/333819

Log:
  Silence non-actionable warnings in vendor code
  
  We can't modify vendor code so there's no signal in warnings from it.
  Similarly -Waddress-of-packed-member is not useful on networking code
  as access to packed structures is fundamental to its operation.
