Hello all,

I need to remap 1 page from user space to kernel and I use get_user_pages_remote for this purpose

ret = get_user_pages_remote(tsk, tsk->mm, offset, 1,

&pinned_page, NULL);

Kernel is 4.9.88

I compiled module for Arm Vertex board and run it under QEMU with no problem

But on Android 9 with this exactly kernel I got Oops:

Unable to handle kernel paging request at virtual address fe002000

pgd = d8c14000

[fe002000] *pgd=00000000

Internal error: Oops: 5 [#1] PREEMPT SMP ARM

I checked config files and did not find any difference( almost except balloon ) in memory related configs.

Does anybody have a clue what is a problem here?

Regards,

Lev
