Subject: s390: remove setting for saved_max_pfn
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8bdc237ac113dd42a1c977c8cd3a65a82f774d5e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

s390: remove setting for saved_max_pfn

The only user of saved_max_pfn in s390 is read_oldmem interface but we
have removed that interface, so saved_max_pfn is now unneeded in s390, and
we needn't set it anymore.
