| |
Marcin Juszkiewicz reported issues while generating syscall table for riscv using 4.20-rc1. The patch refactors our unistd.h files to match some other architectures.
- Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h - Adjust kernel asm/unistd.h
So now asm/unistd.h UAPI header should show all syscalls for riscv.
Before this, Makefile simply put `#include <asm-generic/unistd.h>` into generated asm/unistd.h UAPI header thus user didn't see:
- __NR_riscv_flush_icache - __NR_newfstatat - __NR_fstat
which are supported by riscv kernel.
