e end of the address space. Address those problems by rewriting the kasan population function, splitting it into subfunctions for each different page table level.

Note that the comments come from arm64.

Removing this define also allows us to simplify some compile time logic. This fixes large kernel mappings with a size greater than 128MB, as it is the case for syzbot kernels whose size was just ~130MB. Note that on rv64, for now, we are then limited to PGDIR size for early mapping as we can't use PGD mappings (see [1]). That should be enough given the relative small size of syzbot kernels compared to PGDIR_SIZE which is 1GB.

When kasan is enabled this results in asan stub calls that are unlikely to be resolved by userspace, this just disables KASAN when building the VDSO. Verified the fix on a kernel with KASAN enabled using vDSO selftests.
