No objection from me.

You contributed that file originally with not-really-Linux,
not-really-Xen formatting. The decompressors I added later
based on Linux code all retained the Linux coding style, so getting
the LZO code aligned back is certainly in line with that (and our
general policy).

Not anymore - the Dom0 kernel may come LZO-compressed, and
hence the decompression code is also being used there.
