x86/kasan, mm: Introduce generic kasan_populate_zero_shadow()
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.
