lttng-modules: Backport fixes for kernel instrumentation
This backport fixes from upcoming 2.9.4 release. Those are:
- Fix: vmalloc wrapper on kernel < 2.6.38
- Fix: vmalloc wrapper on kernel >= 4.12
- Add kmalloc failover to vmalloc
- Fix: mmap: caches aliased on virtual addresses
- Fix: update ext4 instrumentation for kernel 4.13
- Fix: Sleeping function called from invalid context
- Fix: sched for v4.11.5-rt1
- Fix: handle missing ftrace header on v4.12
This fix failures in some BSP layers which are using Linux 4.13
already.
