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

soc: xilinx: rename cpu_number1 to dummy_cpu_number

The per cpu variable cpu_number1 is passed to xlnx_event_handler as
argument "dev_id", but it is not used in this function. So drop the
initialization of this variable and rename it to dummy_cpu_number.
This patch is to fix the following call trace when the kernel option
CONFIG_DEBUG_ATOMIC_SLEEP is enabled:
