Do you think the following adjustment make sense or it is definitely wrong?
I can only answer this if I understand which problem it solves. Why do
you need the 2M alignment in this case?

Sorry for the late response，my purpose is that we don't want to enable
KPTI if
KASLR is disabled. For now, if there are some firmware bug, the kernel
image is
relocated which lead to kaslr_requires_kpti() returen
ture(kaslr_offset() > 0).
the change to 2M alignment is a workaround and according to your
explanation,
I don't think the workaround is necessary. I want to make sure that the
above
scene is expected? thanks.
