Fix: remove regmap instrumentation for kernels < 4.1
Modifications to regmap.h instrumentation in mainline Linux kernel has
been no less than erratic. First, the public instrumentation header
regmap.h include a private driver header in Linux 4.0. Then, regmap.h
is moved to the private driver directory in Linux 4.1. To make things
worse, the 4.0 commit has been picked into stable branches of the Linux
kernel.
Since this does not appear to be an instrumentation of utmost
importance, only build this instrumentation probe if the private header
is found in the driver directory (need full kernel sources).
This removes regmap instrumentation for older kernels.

Fix: kmem instrumentation: mm_page_alloc extfrag change_ownership field
Linux kernel 3.12.30 and onward changes the parameter received by this
callback. It's the same type, but the meaning differs. This is why it
did compile fine, but the data gathered did not really represent
change_ownership.
This change has been introduced in the Linux kernel by this commit:

Fix: implement time.h wrapper for FD_ISSET
Kernels v3.4.0 to v3.4.7 still define FD_ISSET, but __FD_ISSET has been
removed. Therefore, we cannot use the FD_ISSET define to find out of we

This issue affects only architectures without efficient unaligned
