Ok.

But then that function receives both the addr and the cpumode, so its
callers should take into account the mixed ip/addr cpumodes, i.e. if we
get a sample with an ip in kernel and an addr in userspace, all we know
is that the ip is in the kernel, so we can either check the x86-specific
(well, specific to archs that share the address space for kernel and
userspace) machine__kernel_ip(addr) and pass a kernel cpu mode to
thread__find_addr(), otherwise ask for thread__find(addr, cpumode=user),
no?

Since this is x86 specific stuff, using machine__kernel_ip(addr) to
figure out the addr cpumode seems the way to go, right?
