The NoMMU kernel is broken for QEMU virt machine from Linux-5.9-rc6 because clint_time_val is used even before CLINT driver is probed at following places: 1. rand_initialize() calls get_cycles() which in-turn uses clint_time_val 2. boot_init_stack_canary() calls get_cycles() which in-turn uses clint_time_val The issue#1 (above) is fixed by providing custom random_get_entropy() for RISC-V NoMMU kernel. For issue#2 (above), we remove dependency of boot_init_stack_canary() on get_cycles() and this is aligned with the boot_init_stack_canary() implementations of ARM, ARM64 and MIPS kernel.
