During this new restart, we turn off the device, but as the uCode failed to initialise it already is turned off. As a consequenc...

Analyze and fix the following issue in the Linux kernel code: kprobes/arm: Fix ldrd/strd emulation
Problem Details: Currently emulate_ldrd and emulate_strd don't even have the adjustment of the PC value, so in case of Rn == PC, it will not update the PC incorrectly but instead load/store from the wrong address. Let's add both the adjustment of the PC value and the check for PC == PC. Signed-off-by: Viktor Rosendah...

Thankfully, we're only interested in fetching the faddr value if srr is enabled, so we can simply make this an RCU sequence and use plain rcu_derefere...
