Ok, so I rebased tip:x86/mm and removed these two commits:

adf9ca9c69a2: x86/boot/compressed/64: Handle 5-level paging boot if kernel is above 4G

 arch/x86/boot/compressed/head_64.S | 127 ++++++++++++++++++++++++++-----------

b91993a87aff: x86/boot/compressed/64: Prepare trampoline memory

 arch/x86/boot/compressed/head_64.S    | 24 ++++++++++-
 arch/x86/boot/compressed/pgtable.h    | 18 ++++++++
 arch/x86/boot/compressed/pgtable_64.c | 79 +++++++++++++++++++++++++++++++++++
 3 files changed, 120 insertions(+), 1 deletion(-)

The other 5-level paging related commits tested out fine and are properly 
fine-grained.

Please split these two patches up - the first patch can probably be split up into 
5 parts or so. Let's start with no more than 5 patches per iteration, ok?

Thanks,

	Ingo
