Details

In the Linux kernel, the following vulnerability has been resolved:

drivers: perf: Do not broadcast to other cpus when starting a counter

This command:

$ perf record -e cycles:k -e instructions:k -c 10000 -m 64M dd if=/dev/zero of=/dev/null count=1000

gives rise to this kernel warning:

That's because the fix in commit 3fec323339a4 ("drivers: perf: Fix panic in riscv SBI mmap support") was wrong since there is no need to broadcast to other cpus when starting a counter, that's only needed in mmap when the counters could have already been started on other cpus, so simply remove this broadcast.
