Andrey Ryabinin 873f59b8bd x86/kasan: Use the same shadow offset for 4- and 5-level paging ... commit 12a8cc7fcf upstream. We are going to support boot-time switching between 4- and 5-level paging. For KASAN it means we cannot have different KASAN_SHADOW_OFFSET for different paging modes: the constant is passed to gcc to generate code and cannot be changed at runtime. This patch changes KASAN code to use 0xdffffc0000000000 as shadow offset for both 4- and 5-level paging. For 5-level paging it means that shadow memory region is not aligned to PGD boundary anymore and we have to handle unaligned parts of the region properly. In addition, we have to exclude paravirt code from KASAN instrumentation as we now use set_pgd() before KASAN is fully ready.
