riscv: mm: add missing memcpy in kasan_init
Hi Atish,
It seems that the panic is due to the missing memcpy during kasan_init.
Could you please check whether this patch is helpful?
When doing kasan_populate, the new allocated base_pud/base_p4d should
contain kasan_early_shadow_{pud, p4d}'s content. Add the missing memcpy
to avoid page fault when read/write kasan shadow region.
Tested on:
- qemu with sv57 and CONFIG_KASAN on.
- qemu with sv48 and CONFIG_KASAN on.
- EPSS
