SubjectNew(?) UBSAN warnings in 4.18.0-rc6-00218-ga26fb01c2879 with gcc-8
After testing 4.18.0-rc6-00192 successfully with gcc-7, I upgraded my 
Debian unstable to latest gcc (now defaults to gcc-8) and compiled latest git
4.18.0-rc6-00218-ga26fb01c2879. The new kernel spits out multiple
UBSAN warnings in different places: in mm, radix-tree and network code.
I have compilead a coubple of kernels with gcc-8 before but most have
been 64-bit, this is the first 32-bit one.
