New Revision: 260440
URL: http://svnweb.freebsd.org/changeset/base/260440

Log:
  Add option USB_HOST_ALIGN to configs that contain 'device usb'.  Setting
  this to the cache line size is required to avoid data corruption on armv4
  and armv5, and improves performance on armv6, in both cases by avoiding
  partial cacheline flushes for USB IO.
  
  All these configs already exist in 10-stable.  A few that don't (and
  thus can't be MFC'd yet) will be committed separately.
