Ok, if we want to unbreak the tools builds, two series are required for
6.12.

[1] which addresses the asm/fence.h path issue
[2] which addresses the same issue, but for non-cross builds

[2] can be pulled to RISC-V fixes, but [1] reside in the bpf-next tree
(target 6.13). Details here: [3].

To reiterate what I asked Andrii, but for RISC-V fixes: Would it be
possible to pull these patches [2] into the RISC-V tree, having a
duplicate set in bpf-next? Or are we stuck with stable backporting, as
Andrii suggests?
