commit efd21e10fc3bf4c6da122470a5ae89ec4ed8d180 upstream.
When enable the kernel debug config, there is below calltrace detected:
BUG: using smp_processor_id() in preemptible [00000000] code: cryptomgr_test/339
caller is debug_smp_processor_id+0x20/0x30
CPU: 9 PID: 339 Comm: cryptomgr_test Not tainted 5.10.63-yocto-standard #1
Hardware name: NXP Layerscape LX2160ARDB (DT)
Call trace:
dump_backtrace+0x0/0x1a0
show_stack+0x24/0x30
dump_stack+0xf0/0x13c
check_preemption_disabled+0x100/0x110
debug_smp_processor_id+0x20/0x30
dpaa2_caam_enqueue+0x10c/0x25c
......
cryptomgr_test+0x38/0x60
kthread+0x158/0x164
ret_from_fork+0x10/0x38
According to the comment in commit ac5d15b4519f("crypto: caam/qi2
- use affine DPIOs "), because preemption is no longer disabled
while trying to enqueue an FQID, it might be possible to run the
enqueue on a different CPU(due to migration, when in process context),
however this wouldn't be a functionality issue. But there will be
above calltrace when enable kernel debug config. So, replace this_cpu_ptr
with raw_cpu_ptr to avoid above call trace.
Fixes:
