+Subject: [PATCH] top: protect against the anomalous 'Mem' graph display
+
+Until this patch, top falsely assumed that there would
+always be some (small) amount of physical memory after
+subtracting 'used' and 'available' from the total. But
+as the issue referenced below attests, a sum of 'used'
+and 'available' might exceed that total memory amount.
+
+I'm not sure if this is a problem with our calculation
+of the 'used' amount, a flaw in the kernel 'available'
+algorithms or some other reason I cannot even imagine.
+
+Anyway, this patch protects against such a contingency
+through the following single line addition of new code
+. if (pct_used + pct_misc > 100.0 || pct_misc < 0) ...
+
+The check for less than zero is not actually necessary
+as long as the source numbers remain unsigned. However
+should they ever become signed, we'll have protection.
+
+[ Most of the changes in this commit simply separate ]
+[ a variable's definition from its associated logic. ]
