Same issue is there in jdk17u-dev repo. This doesn't affect functionality for now.
But this needs to be fixed to avoid possible confusion and for future kernel versions
which might make use of the second parameter of the sys_flush_icache system call.
This is RISC-V specific change. Verified with hotspot:tier1 (fastdebug) on linux-riscv64.
