In the Linux kernel, the following vulnerability has been resolved:
riscv: Fix IPIs usage in kfenceprotectpage()
flushtlbkernel_range() may use IPIs to flush the TLBs of all the cores, which triggers the following warning when the irqs are disabled:

So only flush the local TLB and let the lazy kfence page fault handling deal with the faults which could happen when a core has an old protected pte version cached in its TLB. That leads to potential inaccuracies which can be tolerated when using kfence.
