Description
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:
BUG: sleeping function called from invalid context at include/linux/sched/mm.h:274
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 1, name: swapper/0

CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.1.0 #53
Hardware name: Xilinx Versal vmk180 Eval board rev1.1 (QSPI) (DT)
