When CONFIG_RANDSTRUCT enabled, members of task_struct are randomized. There is a chance that TASK_STACK_CANARY be out of 12bit immediate's range and causes build errors. TASK_STACK_CANARY is naturally aligned, so fix it by replacing ld.d/st.d with ldptr.d/stptr.d which have 14bit immediates.

Hi Huacai,

What about 32bit build in this case?

Use the same solution as other registers, please see: https://lore.kernel.org/loongarch/20251122043634.3447854-7-chenhuacai@loongs...
