Pull weak function declaration removal from Bjorn Helgaas:
 "The "weak" attribute is commonly used for the default version of a
  function, where an architecture can override it by providing a strong
  version.

  Some header file declarations included the "weak" attribute.  That's
  error-prone because it causes every implementation to be weak, with no
  strong version at all, and the linker chooses one based on link order.

  What we want is the "weak" attribute only on the *definition* of the
  default implementation.  These changes remove "weak" from the
  declarations, leaving it on the default definitions"
