84020a8aed
This is an add-on patch for the original series that implemented RISC-V that improves the implementation of Linux emulation for SE mode. Basically it cleans up linux/linux.hh by removing constants that haven't been defined for the RISC-V Linux proxy kernel and rearranging the stat struct so it aligns with RISC-V's implementation of it. It also adds placeholders for system calls that have been given numbers in RISC-V but haven't been given implementations yet. These system calls are as follows: - readlinkat - sigprocmask - ioctl - clock_gettime - getrusage - getrlimit - setrlimit The first five patches implemented RISC-V with the base ISA and multiply, floating point, and atomic extensions and added support for detailed CPU models with memory timing. [Fixed incompatibility with changes made from patch 1.] Signed-off by: Alec Roelke Signed-off by: Jason Lowe-Power <jason@lowepower.com>
