And complicating matters even further, your patch presumes that the
kernel has configured CONFIG_SPARSEMEM_EXTREME in conjunction with
CONFIG_SPARSEMEM. Would it be possible for an s390x to be configured
with just CONFIG_SPARSEMEM alone?
Not sure. I have never tried building s390x kernel configured with just
CONFIG_SPARSEMEM alone.
If so, your patch breaks down.
Or is there another way you can determine which MAX_PHYSMEM_BITS value
is in use?
This value is a #define constant and I dont see any kernel symbol
holding this value which could have been easy way to determine this value.
