================================================================================

The x86intrin code in internal/api/ext_x86_*.h are derived from GCC and Clang.
The only reason why this code is duplicated is the fact that the compiler code
cannot be included into kernel code code as is. Thus, the functions used by
leancrypto are extracted - I wished this would not have been necessary.

Anyhow, the GCC code is: GPL 3. The LLVM code is: Apache License v2.0.

NOTE: The presence of GPL 3 code is NOT considered to taint the leancrypto code
base to the GPL 3 restrictions, because all duplicated code is only and
exclusively inline code (i.e. the upstream code is also inline code) to invoke
the proper compiler intrinsics. Therefore, the duplicated code must be
viewed identically to the regular code which by common approach will not
levy the GPL 3 restrictions on the consuming code. Therefore, in light of this
consideration, leancrypto is still assumed to retain the original license
mentioned above.

Once GCC and Clang could be brought to de-entangle declarations for library code
from the actual intrinsic declarations to invoke compiler built-ins, this
duplicated code can be removed.
