On this machine, a single core Athlon 64 with a 32 bit current Linus' git head kernel, I get a lock-up early in the boot process. (A dmesg output of a successful boot-up of kernel 4.1.0 up to and slightly passed the point where the git head kernel locks up is attached).

A photo of the lock-up appears at:

module: Optimize __module_address() using a latched RB-tree

Currently __module_address() is using a linear search through all
modules in order to find the module corresponding to the provided
address. With a lot of modules this can take a lot of time.

One of the users of this is kernel_text_address() which is employed
in many stack unwinders; which in turn are used by perf-callchain and
ftrace (possibly from NMI context).

So by optimizing __module_address() we optimize many stack unwinders
which are used by both perf and tracing in performance sensitive code.

I am happy to supply further details and run further tests.
