Please note:
  1) The code in BusyBox in GPLv2 (only).
  2) The submitted patch was GPLv2 or later.
  3) The result of "agregating" those two codes is licensed using the common
     denominator, that is GPLv2 (only).

I have thought of a little way to present things. You can see it as a bit
mask, each bit being one license grant. When "agregating" code from different
licenses, the result is licensed under the bitwise-AND of the two (or more)
license grants. If you end up with 0 (no bit set), then there is no common
license, and merging is forbidden (unless you are eager to go to court).

Exemple in this case:
 - bit #0 means licensed under GPLv2
 - bit #1 means licensed under "or any later version"

 - BusyBox has bit #0 set, and bit #1 unset:          01
 - The patch has both bits set (GPLv2, or later):   & 11
 - The result has bit #0 set, and bit #1 unset:     = 01

 - Thus the result is GPLv2 (only).

Yann E. MORIN.
