Thanks for the patch and effort. I can confirm your kernel package boots fine 
on my LeMaker BananaPi.
  $ uname -a
  Linux bananapi 4.9.0-8-armmp-lpae #1 SMP Debian 4.9.144-4 (2019-02-18) armv7l 
GNU/Linux

journalctl also shows no errors that haven't been there before.

Timo

Just to confirm: installed this on the Armada XP on my desk (copy of
the buildd hardware we're using) and it works just fine.

Based on this suggestion and Julien's suggested patch on IRC a couple
hours ago, I've tested the attached patch successfully (as in: from a
busy loop in qemu-system-arm to the “expected” kernel panic, as
discussed in another subthread).

I've uploaded linux-image binaries (armmp and armmp-lpae) here, which
were cross-built through sbuild, thanks to Vagrant's suggestion on IRC:
  https://people.debian.org/~kibi/linux-bug-922478/

which is:
  DEBIAN_KERNEL_DISABLE_DEBUG=yes sbuild -d stretch-proposed-updates -c 
stretch-amd64-sbuild --build=amd64 --profiles='pkg.linux.notools nodoc nopython 
cross pkg.linux.nosource' --host=armhf linux_4.9.144-4.dsc

Checking this on real hardware would be great, trying to put everyone
involved in the loop through cc.

Subject: [PATCH] Update debian/arm-avoid-abi-change-in-4.9.139.patch (Closes:
 #922478).

This makes it take into account the function pointers reordering in
arch/arm/mm/proc-macros.S (addition of check_bugs), fixing the failure
to boot many armhf devices.

With thanks to Adrian Bunk for the hint, and Julien Cristau for the
prospective patch.

2019-02-17 Thread Vagrant Cascadian 
After upgrading to the latest 4.9.x kernel in sid, all of the armhf
boards running this kernel failed to boot.

Adding to the list:

imx6: Cubox-i4pro, Cubox-i4x4, Wandboard Quad
exynos5: Odroid-XU4
exynos4: Odroid-U3
rk3328: firefly-rk3288

So it clearly impacts a wide variety of systems...
