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 ++++++++++++++++++++++++++----------- 1 file changed, 89 insertions(+), 38 deletions(-)
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
