Hm, with the local build test, I get the following error:

CC [M] sound/xen/xen_snd_front_shbuf.o

Adding #include <linux/kernel.h> fixed the issue.

Did you really test your patches with the latest Linus tree?
My bad, it does build for ARM (which is my target), but also does
need "#include <linux/kernel.h>" for x86 which I didn't build this time.
Sorry about that.

Do you want me to resend this single patch or you can make the change
while applying?


Thank you,
