[RFC PATCH V3 30/43] rv64ilp32_abi: kernel/smp: Disable CSD_LOCK_WAIT_DEBUG

[guoren at kernel.org]

From: "Guo Ren (Alibaba DAMO Academy)" <guoren at kernel.org>

The rv64ilp32 abi is based on CONFIG_64BIT, but uses ILP32 for a
smaller cache & memory footprint. So, disable CSD_LOCK_WAIT_DEBUG
to get smaller csd struct.
