svn commit: r361012 - in stable/11/sys: conf modules/drm2/i915kms modules/ipfilter

[Dimitry Andric]

Author: dim

New Revision: 361012
URL: https://svnweb.freebsd.org/changeset/base/361012

Log:
  MFC r305392:
  
  For kernel builds, instead of suppressing certain clang warnings, make
  them non-fatal, so there is some incentive to fix them eventually.
  
  MFC r333819 (by mmacy):
  
  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.
