The RISC-V arch_timer selftests is used to validate Sstc timer
functionality in a guest, which sets up periodic timer interrupts
and check the basic interrupt status upon its receipt.
This KVM selftests was ported from aarch64 arch_timer and tested
with Linux v6.7-rc4 on a Qemu riscv64 virt machine.
---
Changed since v4:
* Rebased to Linux 6.7-rc4
* Included Paolo's patch(01/11) to fix issues with SPLIT_TESTS
* Droped the patch(KVM: selftests: Unify the makefile rule for split targets)
since Paolo's patch had included the fix
* Added new patch(05/11) to include header file vdso/processor.h from linux
source tree to leverage the cpu_relax() definition - Conor/Andrew
* Added new patch(11/11) to enable user configuration of timer error margin
parameter which alleviate the intermitent failure in stress test - Andrew
* Other minor fixes per Andrew's comments
