Just did 5 s2d runs, back-to-back, with Rafael's linux-next branch.
Looks good so far, no hickups. I'll watch it the coming days if there
are any changes.

Reported-and-tested-by: Borislav Petkov <bp@...e.de>

Btw, I'm running with:

CONFIG_ARCH_HAS_ELF_RANDOMIZE=y
CONFIG_RANDOMIZE_BASE=y
CONFIG_RANDOMIZE_MEMORY=y
CONFIG_RANDOMIZE_MEMORY_PHYSICAL_PADDING=0x0

Thanks guys for the fixes.
