  - riscv: Fix IPIs usage in kfence_protect_page() flush_tlb_kernel_range() may use IPIs to flush the TLBs of     all the cores, which triggers the following warning when the irqs are disabled: [ 3.455330] WARNING: CPU:

That leads to potential inaccuracies which can be     tolerated when using kfence. (CVE-2024-53687)
