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

     CC [M]  sound/xen/xen_snd_front_shbuf.o
     In file included from sound/xen/xen_snd_front_shbuf.c:11:0:

     ./arch/x86/include/asm/xen/interface.h:92:21: error: unknown type name 
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?
Yes, it's fine.
Thank you
FWIW, the patches are in topic/xen branch in sound.git tree, and I'll
keep boiling for a while to see if any issues are caught by 0day bot.
Thank you, hope everything goes well

Thank you,
