[PATCH v2 3/4] vmlinux.lds.h: add missing alignment for symbol CRCs

From: Luis Chamberlain
Date: Mon Jan 29 2024 - 14:27:20 EST


Commit f3304ecd7f06 (linux/export: use inline assembler to populate
symbol CRCs") fixed an issue with unexpected padding by adding
asm inline assembly to directly specify the desired data layout.
It however forgot to add the alignment, fix that.
