The patch referenced below moved the loading of segment registers
out of load_up_mmu() in order to do it earlier in the boot sequence.
However, the secondary CPU still needs it to be done when loading up
the MMU.

Sorry patchwork didn't pick that up and I missed it. The AUTOSEL bot
will probably pick it up anyway though.
Don't worry, this was unneeded because we added KASAN in 5.2.
My mistake.
Christophe
cheers
