Sorry for the too much late reply, Kirill.
Yes, you can skip it.

As Nitin said in that patch's thread, zsmalloc has assumed
PFN_BIT is (BITS_PER_LONG - PAGE_SHIFT) so it already covers
X86_5LEVEL well, I think.

In summary, there is no need to change it.
I hope it helps to merge this patchset series.

Thanks.
