Hi all!
I've tried to build the latest preempt-rt kernel from the
`v4.14/standard/preempt-rt/base`
and it fails to build. These are the hashes I've used:
This should go to the linux-yocto list, since that's where
people interested in the linux-yocto kernel variants will
notice it.
In this case, there was a bad merge. If you check the
preempt-rt branches of 4.14 there's a fix queued, but I
haven't sent SRCREV updates yet.

```
LINUX_VERSION = "4.14.71"
SRCREV_machine = "c37a14708f5b618602f84f83f902346e055824c3"
SRCREV_meta = "1fb0b0379fb5883ce5af7485374e3f78ee4272d3"
```
And the errors I get are:
```

Is there any change that the latest rt44 patches are nor applied?
Thanks!
