Arnd Bergmann ec437d0159 kernel: trace: preemptirq_delay_test: use offstack cpu mask ...

[ Upstream commit adc353c0bf ]

A CPU mask on the stack is broken for large values of CONFIG_NR_CPUS:

kernel/trace/preemptirq_delay_test.c: In function ‘preemptirq_delay_run’:
kernel/trace/preemptirq_delay_test.c:143:1: error: the frame size of 8512 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]

Fall back to dynamic allocation here.
