NAME

       get_unaligned - get value from possibly mis-aligned location

SYNOPSIS

       get_unaligned  (ptr);

ARGUMENTS

       ptr    pointer to value

DESCRIPTION

       This  macro  should  be  used  for accessing values larger in size than
       single bytes at locations that are expected to be  improperly  aligned,
       e.g. retrieving a u16 value from a location not u16-aligned.

       Note   that   unaligned   accesses   can  be  very  expensive  on  some
       architectures.
