Subject: [PATCH] kasan, mm: fix build issue with asmlinkage

    kasan: shadow declarations only for software modes

introduces a build failure when it removed an include for linux/pgtable.h
It actually only needs linux/linkage.h

Test builds on both x86_64 and arm build cleanly

Fixes:   2df573d2ca4c ("kasan: shadow declarations only for software modes")
