* bionic/linux: 4.15.0-166.174 -proposed tracker (LP: #1953667)
* Ubuntu version macros overflow with high ABI numbers (LP: #1953522)
- SAUCE: Revert "stable: clamp
Confirmed that lttng-modules can now be built with the derivative
kernels based on linux/4.15.0-166.174 which have high ABI numbers and
were causing lttng-modules build to fail previously.
Examples:
* bionic/linux-dell300:
- before:
Based on the updated bionic:linux kernel (4.15.0-166.174) we have spun
the bionic:linux-snapdragon derivative which was failing to build lttng-
modules with the previous base. This now works as well as the base
kernel (still) passing that test:

Looking at lttng-modules upstream I saw that this got fixed by them for
Xenial in some middle way (that and there was a later patch to cast

bug with the results. If the problem is solved, change the tag
'verification-needed-bionic' to 'verification-done-bionic'. If the
problem still exists,
