[ CC PaX and David Woodhouse ]

I remembered that CONFIG_FTRACE is not working correct (details see
[1] as explained by PaX).
Thus I disabled it (see 4.4.4-2-llvmlinux-amd64).
That 'mcount' bogus lines are gone.

In a 2nd test-build I turned off CONFIG_PROVE_LOCKING en-plus as it
enables CONFIG_TRACE_IRQFLAGS (4.4.4-4-llvmlinux-amd64).

The call-traces when booting and/or un-/re-plugging my USB-mouse are
still alive in all built clang-compiled Linux-kernels.

dmesg-output for -4 kernel is attached, it includes the usbhid
test-patch from Alan Stern (plus some other CC:stable fixes against
Linux v4.4.4).

Hope this helps.
