The .align directive has inconsistent behavior across architectures. Use .balign instead everywhere. This is a no-op for s390, but with this there is no mix in using .align and .balign anymore. Future code is supposed to use only .balign.

* insn_page is a special 4k aligned dummy function for kprobes.

* It will contain all kprobed instructions that are out-of-line executed.
|
|
* The page must be within the kernel image to guarantee that the
|
|
* out-of-line instructions are within 2GB distance of their original
|
|
* location. Using a dummy function ensures that the insn_page is within

|
|
* the beginning on, thus avoiding to split large mappings if the page
|
|
* would be in the data section instead.
