Guo Ren 1509e93916 riscv: Fixup race condition on PG_dcache_clean in flush_icache_pte ... commit 950b879b7f0251317d26bae0687e72592d607532 upstream. In commit 588a513d3425 ("arm64: Fix race condition on PG_dcache_clean in __sync_icache_dcache()"), we found RISC-V has the same issue as the previous arm64. The previous implementation didn't guarantee the correct sequence of operations, which means flush_icache_all() hasn't been called when the PG_dcache_clean was set. That would cause a risk of page synchronization.
