Hi,
When trying to test my coresight patches, I found that etr,etf and stm
device nodes are missing from /dev.
Bisection gives this as the bad commit.

driver: base: Disable CONFIG_UEVENT_HELPER by default
Since commit 7934779a69f1184f ("Driver-Core: disable /sbin/hotplug by
default"), the help text for the /sbin/hotplug fork-bomb says
"This should not be used today [...] creates a high system load, or
[...] out-of-memory situations during bootup". The rationale for this
was that no recent mainstream system used this anymore (in 2010!).
A few years later, the complete uevent helper support was made
optional
in commit 86d56134f1b67d0c ("kobject: Make support for uevent_helper
optional."). However, if was still left enabled by default, to
support
ancient userland.
Time passed by, and nothing should use this anymore, so it can be
disabled by default.
