Yes. The patches are generated using git format-patch and sent by
git send-email. That's how it always created patches for me. I am not sure if

We should be able to copy upto count bytes

Why?

Without this we end up doing

+    struct kvm_get_htab_buf {
+        struct kvm_get_htab_header header;
+        /*
+         * Older kernel required one extra byte.
+         */
+        unsigned long hpte[3];
+    } hpte_buf;


even though we are only looking for one hpte entry.

Ok, please give me an example with real numbers and why it breaks.

Didn't quiet get what you are looking for. As explained before, we now
need to pass an array with array size 3 even though we know we need to
read only 2 entries because kernel doesn't loop correctly.
