These build failures are still triggering upstream:

 arch/x86/xen/trace.c:44:2: error: array index in initializer not of integer type
 arch/x86/xen/trace.c:44:2: error: (near initialization for ‘xen_hypercall_names’)
 arch/x86/xen/trace.c:45:1: error: ‘__HYPERVISOR_arch_4’ undeclared here (not in a function)
 arch/x86/xen/trace.c:45:2: error: array index in initializer not of integer type
 arch/x86/xen/trace.c:45:2: error: (near initialization for ‘xen_hypercall_names’)

Oh, that I haven't seen. Can you send me the .config for that please.

You can't be trying very hard then.  I see lots of these (but no,

Ah, I am getting it now. Thanks for reporting it.

This should do the trick:

Acked-by: Randy Dunlap <redacted>

That patch did the trick here too:

Acked-by: Ingo Molnar <redacted>

Except that i'm still seeing the occasional build failure - see the 
error log below. Config attached.

Much appreciate for the report. I believe this fix (which I think hit
linux-next yesterday?) should do that:

     xen/tracing: it looks like we wanted CONFIG_FTRACE
    
    Apparently we wanted CONFIG_FTRACE rather the CONFIG_FUNCTION_TRACER.

I'm not sure this is correct either.  Maybe it should be
CONFIG_TRACEPOINTS?  Steven?

Actually, I believe the correct answer is:

CONFIG_EVENT_TRACING
