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.

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.

Planning to send all of the bug-fixes in my branch to Linus tomorrow - just
leaving it in linux-next for the full 24-hrs at least to make sure nothing
else goes haywire.
