Subject: [PATCH AUTOSEL 6.3 5/7] riscv: Unconditionnally select KASAN_VMALLOC if KASAN

From: Alexandre Ghiti <alexghiti@...osinc.com>

[ Upstream commit 864046c512c2cd8418dc928b91981fb12a80396c ]

If KASAN is enabled, VMAP_STACK depends on KASAN_VMALLOC so enable
KASAN_VMALLOC with KASAN so that we can enable VMAP_STACK by default.
