Subject: arm64: remove unused ARCH_PFN_OFFSET
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bf6b3fed186665cecbf0cf8be72da15d6585bfb0;p=thirdparty%2Flinux.git

arm64: remove unused ARCH_PFN_OFFSET

This is only relevant to the FLATMEM memory model, which isn't an option
since commit 782276b4d0ad ("arm64: Force SPARSEMEM_VMEMMAP as the only
memory management model").
