Hi all,

Today's linux-next merge of the risc-v tree got a conflict in:

drivers/perf/Kconfig

between commits:

c2b24812f7bc ("perf: starfive: Add StarLink PMU support")
f0dbc6d0de38 ("perf: starfive: Only allow COMPILE_TEST for 64-bit architectures")

from the arm64 tree and commit:

bc969d6cc96a ("perf: RISC-V: Introduce Andes PMU to support perf event sampling")

from the risc-v tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
