When encountering this issue while compiling the kernel, should I choose 1, 2, or 3?

* Restart config...

* Memory initialization

Initialize kernel stack variables at function entry
> 1. no automatic stack variable initialization (weakest) (INIT_STACK_NONE)
2. pattern-init everything (strongest) (INIT_STACK_ALL_PATTERN) (NEW)
3. zero-init everything (strongest and safest) (INIT_STACK_ALL_ZERO) (NEW)

It depends on what this kernel will be for. I would go with #3 and make a note that it was chosen so if the kernel fails that choice is in account when tracking down a reason.

Sometimes there can be a cascading effect when certain options are combined that could prevent the kernel from compiling. Though this is all part of the process of compiling a useful kernel.

I just want to know which compatibility is used by default.
I used to compile directly without popping up this prompt. But now it pops up and I want to know the difference between these three options. You must select a number to continue.
Thank you for your reply!

The default in previous kernels is (1).
