Yah, acpi.c didn't have any copyright banner so I used my 'default'
template for new files here to cover any additions, but that does give
a misleading impression.

I'm not sure how this is normally addressed, but I'm planning on just
continuing the acpi.c tradition of *not* adding copyright notices for new
code, and simply document that the contents of the file are mostly movement
from acpi.c

AFAICT the full author list for the changes in question are, in
alphabetical order:

Chao Fan <>
Junichi Nomura <>
Borislav Petkov <>

Chao, Junichi, Borislav,

If you would like to be listed as an author in efi.c (which is mainly just a
movement of EFI config table parsing code from acpi.c into re-usable helper
functions in efi.c), please let me know and I'll add you.

Otherwise, I'll plan on adopting the acpi.c precedent for this as well, which
is to not list individual authors, since it doesn't seem right to add Author
fields retroactively without their permission.
