The microblaze test failures are triggered by commit 721f4a6526da
("mm/memblock: remove empty dummy entry"). The fix is at
https://lore.kernel.org/all/20240729053327.4091459-1-rppt@kernel.org/
and should hopefully be sent upstream in the near future.

The ppc failures bisect to commit 6b0e82791bd0 ("powerpc/e500: switch to 64
bits PGD on 85xx (32 bits)"). This commit is related to other hugepage
related patches and can not easily be reverted. I don't know the status.
Given the context (changing the pgd sixe) it may well be a qemu problem.

The mips64 test failure is a networking interface failure. It started
happening a week or two ago. The problem is spurious and thus difficult
to bisect.

There is also a spurious failure with parisc64 images, triggered by commit
c37927a203fa ("genirq: Set IRQF_COND_ONESHOT in request_irq()"). The same
problem is also seen in v6.10.3 where that patch was backported. This is a
heisenbug: Any debugging added to figure out what is going on makes it
disappear. I don't know if it is a race condition or a bug in qemu or
something else. I did not see this problem with v6.11-rc2 but with an
interim image (v6.11-rc1-272-g17712b7ea075).
