Yes, I think a macro would be fine. Should we use cache_desc.block_size or L1_CACHE_BYTES? It doesn't make much difference as L1_CACHE_BYTES is defined as 16 bytes which is the minimum block size and using that will always invalidate a whole block. It would be good to have a comment explaining why using L1_CACHE_BYTES is enough.

However a zeroed pt_regs structure is created at build time and kept at top of the init stack for task_pt_regs() to function properly with the init task in the same manner as a normal task with user level context.

Besides, task_pt_regs() no longer converts a fixed offset from top of a task kernel stack to a pt_regs structure pointer, but rather returns whatever in the thread_info.user_pt_regs field, which is initialized at build time to '(struct pt_regs *)TOP_OF_INIT_STACK - 1' for the init task.

As a result, there is no point to reserve any padding space at top of the init stack, so remove the padding space.

A FRED event frame could contain different amount of information for different event types, e.g., #MCE could push extra bytes of information, or perhaps even for different instances of the same event type.
