Hi Ritesh,

Thanks, your diff fixes the issue on the Turris 1.1.

Test results:

- 6.18.55, CONFIG_JUMP_LABEL=y: Without your diff, the board hangs
  during boot module loading in 5/5 boots and is reset by the
  watchdog. With maxcpus=1, it boots. With your diff, it boots
  successfully in 10/10 attempts, with no warnings or oopses.
- 6.18.55, CONFIG_JUMP_LABEL=n: With your diff, 10/10 successful boots.
- 7.3-rc1, CONFIG_PROVE_LOCKING=y: With your diff and jump labels both
  enabled and disabled, 3/3 successful boots in each configuration.
  The smp.c:917 warning from my report is gone, and lockdep reports
  no issues.

Feel free to add:

Tested-by: Josef Schlehofer <pepe.schlehofer@gmail.com>

Josef
