Ok, I forgot about 64bit machines. BTW also your '20-' is obviously
_wrong_ because you are supposing that sizeof(long)-sizeof(short) is 2.

So this seems to me the only _ugly_ solution:

--- 2.3.17/include/linux/kernel.h Wed Sep 8 18:18:56 1999
+++ kernel.h Fri Sep 10 14:13:09 1999
@@ -94,8 +94,8 @@
unsigned long totalswap; /* Total swap space size */
unsigned long freeswap; /* swap space still available */
unsigned short procs; /* Number of current processes */
- unsigned long totalbig; /* Total big memory size */
- unsigned long freebig; /* Available big memory size */
+ unsigned long totalbig __attribute__((packed)); /* Total big memory size */
+ unsigned long freebig __attribute__((packed)); /* Available big memory size */
char _f[22-2*sizeof(long)]; /* Padding: libc5 uses this.. */

Anyway it's clear that such structure is very _bad_ designed w.r.t. 64bit
