[stable] KASLR could not find suitable E820 region...

Hi Kees,

We noticed the below boot errors in stable kernels 3.16.7 and 3.17.2
on real hardwares:

early console in decompress_kernel
KASLR could not find suitable E820 region...

Decompressing Linux... Parsing ELF... Performing relocations...

32-bit relocation outside of kernel!

These kconfig options are enabled:

CONFIG_RANDOMIZE_BASE=y
CONFIG_RANDOMIZE_BASE_MAX_OFFSET=0x40000000

Before digging further, we'd like to ask for a quick answer that
whether they've been fixed by some commit in current mainline kernel?

Thanks,
Fengguang
