Key Changes Compared to Version 2:
Patch 1: changed loop conditions to avoid setting r0
Patch 7: replaced manual byte swapping with const_le32
Patch 9: used ROUND_DOWN to align the stack

Mark Corbin (15):
  bsd-user: Implement RISC-V CPU initialization and main loop
  bsd-user: Add RISC-V CPU execution loop and syscall handling
  bsd-user: Implement RISC-V CPU register cloning and reset functions
  bsd-user: Implement RISC-V TLS register setup
  bsd-user: Add RISC-V ELF definitions and hardware capability detection
  bsd-user: Define RISC-V register structures and register copying
  bsd-user: Add RISC-V signal trampoline setup function
  bsd-user: Implement RISC-V sysarch system call emulation
  bsd-user: Add RISC-V thread setup and initialization support
  bsd-user: Define RISC-V VM parameters and helper functions
  bsd-user: Define RISC-V system call structures and constants
  bsd-user: Define RISC-V signal handling structures and constants
  bsd-user: Implement RISC-V signal trampoline setup functions
  bsd-user: Implement 'get_mcontext' for RISC-V
  bsd-user: Implement set_mcontext and get_ucontext_sigreturn for RISCV

Warner Losh (2):
  bsd-user: Add generic RISC-V64 target definitions
  bsd-user: Add RISC-V 64-bit Target Configuration and Debug XML Files
