The root cause of the bug was fixed in v4.17 by 5c9b0b1c4988 ("x86/boot/compressed/64: Set up GOT for paging_prepare() and cleanup_trampoline()"). The only pending patch I have at the moment is http://lkml.kernel.org/r/20180612103657.18041-1-kirill.shutemov@linux.intel.com Do you want me to resend it again? -- Kirill A. Shutemov
