Hi,

I compiled Linus' Tree (40471856) on my x86_64 machine, once without the patch 
and once with the patch.


size vmlinux-with*
   text    data     bss     dec     hex filename
7996901 1236036 1118208 10351145         9df229 vmlinux-withoutpatch
7996554 1235988 1118208 10350750         9df09e vmlinux-withpatch

ls -la vmlinux-with*
-rwxr-xr-x 1 peter users 18921237 27. Mär 17:40 vmlinux-withoutpatch
-rwxr-xr-x 1 peter users 18921333 27. Mär 17:58 vmlinux-withpatch
