Outside of the normal patch refreshes and boot issues, there are

For ORC_UNWINDER support in x86-64:
DEPENDS += "${@bb.utils.contains('ARCH', 'x86', 'elfutils-
native elfutils', '', d)}"
do we need both target and host elfutils
Yup. There were references to both. Some had to run for hostcc
and others in the target arch.
Just for reference this is pretty bad for performance as it delays the
kernel compile until some substantial parts of userspace build.
On a second look, I can likely turn off the target part, if someone
wants it, they can always install the package (or it could be a
rdepends).
I'll amend the commit and leave it on that branch with just the
DEPENDS on the -native version.
Is ORC_UNWINDER useful and commonly used?
The upstream kernel commit turned it on by default, I turned it off in
the kernel-cache, but I wanted to make sure the dependency was
in place.
The commit series from Josh Poimboeuf all lead to it being on as
the default choice (even with a slight overhead).
