Max Filippov e64681b487 xtensa: use MEMBLOCK_ALLOC_ANYWHERE for KASAN shadow map 
KASAN shadow map doesn't need to be accessible through the linear kernel
mapping, allocate its pages with MEMBLOCK_ALLOC_ANYWHERE so that high
memory can be used. This frees up to ~100MB of low memory on xtensa
configurations with KASAN and high memory.

Cc: stable@vger.kernel.org # v5.1+
Fixes: f240ec09bb ("memblock: replace memblock_alloc_base(ANYWHERE) with memblock_phys_alloc")
