Subject[PATCH] x86/boot: use .code16 instead of .code16gcc
From
Date
This reverts commit 28b48688 ("x86, boot: use .code16gcc instead
of .code16").

Versions of binutils older than 2.16 are already not working, so this
workaround is no longer necessary either.

Since I just made .code16 work in LLVM, this removes one more barrier to
building the kernel with LLVM/clang. And it looks like 'clang -m16' for
the C code in arch/x86/boot shouldn't actually be that hard to do now
either.
