Introduce generic kasan_populate_zero_shadow(shadow_start, shadow_end). This function maps kasan_zero_page to the [shadow_start, shadow_end] addresses. This replaces x86_64 specific populate_zero_shadow() and will be used for ARM64 in follow on patches. The main changes from original version are: * Use p?d_populate*() instead of set_p?d() * Use memblock allocator directly instead of vmemmap_alloc_block() * __pa() instead of __pa_nodebug(). __pa() causes troubles iff we use it before kasan_early_init(). kasan_populate_zero_shadow() will be used later, so we ok with __pa() here.
