Hi Mikhail,
Could you please clarify why these are not two separate commits?
- Update s390x_vr_IS_VMALLOC_ADDR() to include a non-zero
vmalloc_start
check, making it consistent with s390x_generic_IS_VMALLOC_ADDR().
This one looks as a bug fix to me.
- Remove redundant vmalloc_start check from s390x_kvtop().
And this one is a follow-up optimization, unless there was
a reason for this check before commit d0164e7 ("s390x: uncouple
physical and virtual memory spaces"). Do you have any ideas?
