For code that needs the ultimate performance (it can inline the @cmp
function too) or simply needs to avoid calling external functions for
whatever reason, provide an __always_inline variant of bsearch().
[ tglx: Renamed to __inline_bsearch() as suggested by Andy ]

Comparator function type, cmp_func_t, is defined in the types.h,
use it in bsearch() and, thus, add more sense to the corresponding
comment in the code.

For files only using THIS_MODULE and/or EXPORT_SYMBOL, map
them onto including export.h -- or if the file isn't even
using those, then just delete the include. Fix up any implicit
include dependencies that were being masked by module.h along
the way.

There a large number hand-coded binary searches in the kernel (run
"git grep search | grep binary" to find many of them). Since in my
experience, hand-coding binary searches can be error-prone, it seems
worth cleaning this up by providing a generic binary search function.
This generic binary search implementation comes from Ksplice. It has
the same basic API as the C library bsearch() function. Ksplice uses
it in half a dozen places with 4 different comparison functions, and I
think our code is substantially cleaner because of this.
