This patch set refactors modpost first to make it easier to add new code. My goals: - Refactors EXPORT_SYMBOL, <linux/export.h> and <asm/export.h>. You can still put EXPORT_SYMBOL() in *.S file, very close to the definition, but you do not need to care about whether it is a function or a data. This removes EXPORT_DATA_SYMBOL(). - Re-implement TRIM_UNUSED_KSYMS in one-pass. This makes the building faster. - Move the static EXPORT_SYMBOL check to modpost. This also makes the building faster. This patch set is applicable to linux-next 20230608.
