This series fixes some boot time printf output to stderr by adding os_info() and os_warn(). The information-level messages via os_info() are suppressed when "quiet" kernel option is specified. Also the last one allows user to pass "console=" option to kernel. Note that the output of --help and --version are still sent to stdout since they are intentionally shown by the user. Changes from v1: - Introduce os_info() and os_warn() to replace most of printf() instead of reusing non_fatal(). - Replace fprintf(stderr, ...) with os_warn() for error messages. Thank you, --- Masami Hiramatsu (6): um: Use printk instead of printf in make_uml_dir um: Add os_info() for pre-boot information messages um: Use os_info for the messages on normal path um: Add os_warn() for pre-boot warning/error messages um: Use os_warn to print out pre-boot warning/error messages um: console: Ignore console= option arch/um/drivers/stdio_console.c | 3 +++ arch/um/include/shared/os.h | 4 ++++ arch/um/kernel/physmem.c | 10 +++++----- arch/um/kernel/um_arch.c | 16 +++++++++------- arch/um/kernel/umid.c | 4 ++-- arch/um/os-Linux/execvp.c | 2 +- arch/um/os-Linux/main.c | 9 ++++----- arch/um/os-Linux/mem.c | 28 ++++++++++++++-------------- arch/um/os-Linux/start_up.c | 28 +++++++++++++++------------- arch/um/os-Linux/umid.c | 19 +++++++++++-------- arch/um/os-Linux/util.c | 34 ++++++++++++++++++++++++++++++++++ 11 files changed, 102 insertions(+), 55 deletions(-) -- Masami Hiramatsu
