A perf interrupt hits and ends up calling # trace_hardirqs_off() when restoring interrupt flags to a disable # state. # # Fix this by disabling perf interrupts as well while adjusting irq # tracing state. # # Add a debug check that catches the condition sooner. # # Fixes: 68b34588e202 ("powerpc/64/sycall: Implement syscall entry/exit logic in C") # Cc: stable@vger.kernel.org # v5.7+ #
