Fix build warnings in the arch_numa common code:

../include/linux/kern_levels.h:5:18: warning: format '%Lx' expects argument of type 'long long unsigned int', but argument 3 has type 'phys_addr_t' {aka 'unsigned int'} [-Wformat=]
../drivers/base/arch_numa.c:360:56: note: format string is defined here
  360 |    pr_warn("Warning: invalid memblk node %d [mem %#010Lx-%#010Lx]\n",
../drivers/base/arch_numa.c:435:39: note: format string is defined here
  435 |  pr_info("Faking a node at [mem %#018Lx-%#018Lx]\n", start, end - 1);

Fixes: ae3c107cd8be ("numa: Move numa implementation to common code")

Thanks, this is on for-next.  Did you, by any chance, find %Lx documented
anywhere?  It's not ISO C and the GCC source code says it's a GNU extension,
but I couldn't find it in the documentation (or even where to add it, which I
guess is how I forgot to send my version fo the patch).

'man sprintf' says this:

       As  a nonstandard extension, the GNU implementations treats ll and L as
       synonyms, so that one can, for example, write llg (as a synonym for the
       standards-compliant  Lg) and Ld (as a synonym for the standards compli-
       ant lld).  Such usage is nonportable.


and linux/lib/vsprintf.c has some handling for it:

	if (qualifier == 'L')
		spec->type = FORMAT_TYPE_LONG_LONG;

and

		case 'L':
			if (is_sign)
				*va_arg(args, long long *) = val.s;
			else
				*va_arg(args, unsigned long long *) = val.u;
			break;


Does that help?

The manpage does it, I guess I just wasn't reading closely enough. Thanks!
