Ovidiu Panait 17488d3e1d lttng-modules: Fix "LTTng: vmalloc_sync_all symbol lookup failed" warnings
Fix the following warnings introduced after backporting linux kernel commit [1]
to stable branches:
# lttng create session
...
[  483.242037] LTTng: vmalloc_sync_all symbol lookup failed.
[  483.257056] Page fault handler and NMI tracing might trigger faults.
...

These patches should be dropped when a new stable 12.0 release is available.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
