tag 662658 +patch
kthxbye
Hi!
The patch below compiles on both linux-amd64 and kfreebsd-amd64. I
have tested the resulting binary on both architectures and it seems to
work. output of `x86info -a` on the same hardware (Thinkpad X220 with
Intel i5 2520M) is identical (apart from 2 different register
assignments).
The first hunk is needed to build (header doesn't exist on
!linux). The second part is taken from FreeBSD Ports as well. I haven't
included the conditionals on kernel version as the "old" way is suited
for pre-squeeze kernels and not relevant to us (the freebsd patch adds
the new interface).
Regards
Christoph
