trivia:

Using %-21s would do the same as padding the format
string argument and would create smaller object code.

	offset += scnprintf(buf + offset, PAGE_SIZE - offset,
			    "%-21s \t(0x%lX)\t 0x%08X\n", "HOST_SIGNATURE",

Using an extra space before a tab is odd.

Using a space after a tab is odd too.

etc...
