Also, support for certain number of other system calls is\ndropped in nanoMIPS (those are most of the time obsoleted system\ncalls).\n\nWithout this patch, build for nanoMIPS would fail.\n\nReviewed-by: Richard Henderson <richard.henderson@linaro.org>\nReviewed-by: Aleksandar Markovic <amarkovic@wavecomp.com>\nSigned-off-by: Aleksandar Markovic <amarkovic@wavecomp.com>\nSigned-off-by: Stefan Markovic <smarkovic@wavecomp.com>\n---\n linux-user/strace.c | 14 +++++++++++++-\n linux-user/syscall.c | 29 +++++++++++++++++++++++++++++\n 2 files changed, 42 insertions(+), 1 deletion(-)", "diff": "diff --git a/linux-user/strace.c b/linux-user/strace.c\nindex bd897a3..33f4a50 100644\n--- a/linux-user/strace.c\n+++ b/linux-user/strace.c\n@@ -2304,7 +2304,19 @@ print_statfs(const struct syscallname *name,\n print_pointer(arg1, 1);\n print_syscall_epilogue(name);\n }\n-#define print_statfs64 print_statfs\n+#endif\n+\n+#ifdef TARGET_NR_statfs64\n+static void\n+print_statfs64(const struct syscallname *name,\n+ abi_long arg0, abi_long arg1, abi_long arg2,\n+ abi_long arg3, abi_long arg4, abi_long arg5)\n+{\n+ print_syscall_prologue(name);\n+ print_string(arg0, 0);\n+ print_pointer(arg1, 1);\n+ print_syscall_epilogue(name);\n+}\n #endif\n \n #ifdef TARGET_NR_symlink\ndiff --git a/linux-user/syscall.c b/linux-user/syscall.c\nindex dfc851c..3d57966 100644\n--- a/linux-user/syscall.c\n+++ b/linux-user/syscall.c\n@@ -7286,6 +7286,9 @@ static inline int target_to_host_mlockall_arg(int arg)\n }\n #endif\n \n+#if (defined(TARGET_NR_stat64) || defined(TARGET_NR_lstat64) || \\\n+ defined(TARGET_NR_fstat64) || defined(TARGET_NR_fstatat64) || \\\n+ defined(TARGET_NR_newfstatat))\n static inline abi_long host_to_target_stat64(void *cpu_env,\n abi_ulong target_addr,\n struct stat *host_st)\n@@ -7348,6 +7351,7 @@ static inline abi_long host_to_target_stat64(void *cpu_env,\n \n return 0;\n }\n+#endif\n \n /* ???
