Result: Xorg works.
- Can you bisect between 887f3ceb51cd[good] and 56bec2f9d4d0[bad] to
identify first bad commit that stops after loading the dtb and uImage ?
- Once that first bad commit is identified, can you check whether
the preceeding commit with cherry-picked 525642624783 has Xorg
working or not ?
Thanks

git bisect start
git bisect good 887f3ceb51cd
git bisect bad 56bec2f9d4d0
git bisect good -- Xorg restarts again and again but we are looking
for the first bad commit that stops the boot after loading the dtb and
uImage.
git bisect good -- Xorg restarts again and again.
git bisect good -- Xorg restarts again and again.
git bisect good -- Xorg restarts again and again.

powerpc/mm/64s: Add _PAGE_KERNEL_ROX
In the past we had a fallback definition for _PAGE_KERNEL_ROX, but we
removed that in commit d82fd29c5a8c ("powerpc/mm: Distribute platform
specific PAGE and PMD flags and definitions") and added definitions
for each MMU family.
However we missed adding a definition for 64s, which was not really a
bug because it's currently not used.
But we'd like to use PAGE_KERNEL_ROX in a future patch so add a
definition now.

Xorg works after compiling with the cherry-pick of 525642624783.
Hi All,
I compiled and tested the latest git kernel with the new PowerPC updates
5.13-2 today. Unfortunately the Xorg issue still exists.
If I revert the PowerPC updates 5.13-1 and 5.13-2 then Xorg works
without any problems.
Please check the BookE changes in the PowerPC updates 5.13-1 because my
Book3S machines aren't affected by this issue.
Thanks,
Christian
