[PATCH v11 7/9] arm64/kasan: add and use kasan_map_populate()

[Pavel Tatashin]

BTW, don't we need the same aligments inside for_each_memblock() loop?

How about change kasan_map_populate() to accept regular VA start, end
address, and convert them internally after aligning to PAGE_SIZE?

Thank you,
Pavel
