Subject: [PATCH v4 6/6] riscv: Unconditionnally select KASAN_VMALLOC if KASAN
Date: Fri,  3 Feb 2023 08:52:32 +0100	[thread overview]
Message-ID: <20230203075232.274282-7-alexghiti@rivosinc.com> (raw)
In-Reply-To: <20230203075232.274282-1-alexghiti@rivosinc.com>

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.
