Commit 0c8c0f03e3a2 ("x86/fpu, sched: Dynamically allocate 'struct fpu'") moved the thread_struct to the bottom of task_struct. As a result, the offset is now too large to be used in an immediate add on arm64 with some kernel configs:arch/arm64/kernel/entry.S: Assembler messages: arch/arm64/kernel/entry.S:588: Error: immediate out of range arch/arm64/kernel/entry.S:597: Error: immediate out of range This patch calculates the offset using an additional register instead of an immediate offset.
