From: Jeff Dike Get rid of a bunch of unused stuff - cpu_feature had no users linux_prog is little-used, so its declaration is moved to the user for easy deletion when the whole file goes away a long-unused debugging aid in helper.c is gone Signed-off-by: Jeff Dike Cc: Paolo 'Blaisorblade' Giarrusso Signed-off-by: Andrew Morton --- arch/um/include/kern_util.h | 1 - arch/um/include/user_util.h | 1 - arch/um/kernel/tt/gdb.c | 2 ++ arch/um/os-Linux/helper.c | 11 ----------- arch/um/os-Linux/main.c | 8 +------- arch/um/sys-i386/bugs.c | 23 ----------------------- arch/um/sys-x86_64/bugs.c | 23 ----------------------- 7 files changed, 3 insertions(+), 66 deletions(-) diff -puN arch/um/include/kern_util.h~uml-delete-unused-code arch/um/include/kern_util.h --- a/arch/um/include/kern_util.h~uml-delete-unused-code +++ a/arch/um/include/kern_util.h @@ -23,7 +23,6 @@ struct kern_handlers { extern const struct kern_handlers handlinfo_kern; extern int ncpus; -extern char *linux_prog; extern char *gdb_init; extern int kmalloc_ok; extern int jail; diff -puN arch/um/include/user_util.h~uml-delete-unused-code arch/um/include/user_util.h --- a/arch/um/include/user_util.h~uml-delete-unused-code +++ a/arch/um/include/user_util.h @@ -60,7 +60,6 @@ extern void kill_child_dead(int pid); extern int cont(int pid); extern void check_sigio(void); extern void arch_check_bugs(void); -extern int cpu_feature(char *what, char *buf, int len); extern int arch_handle_signal(int sig, union uml_pt_regs *regs); extern int arch_fixup(unsigned long address, void *sc_ptr); extern void arch_init_thread(void); diff -puN arch/um/kernel/tt/gdb.c~uml-delete-unused-code arch/um/kernel/tt/gdb.c --- a/arch/um/kernel/tt/gdb.c~uml-delete-unused-code +++ a/arch/um/kernel/tt/gdb.c @@ -115,6 +115,8 @@ struct gdb_data { int err; }; +extern char *linux_prog; + static void config_gdb_cb(void *arg) { struct gdb_data *data = arg; diff -puN arch/um/os-Linux/helper.c~uml-delete-unused-code arch/um/os-Linux/helper.c --- a/arch/um/os-Linux/helper.c~uml-delete-unused-code +++ a/arch/um/os-Linux/helper.c @@ -25,23 +25,12 @@ struct helper_data { char *buf; }; -/* Debugging aid, changed only from gdb */ -int helper_pause = 0; - -static void helper_hup(int sig) -{ -} - static int helper_child(void *arg) { struct helper_data *data = arg; char **argv = data->argv; int errval; - if (helper_pause){ - signal(SIGHUP, helper_hup); - pause(); - } if (data->pre_exec != NULL) (*data->pre_exec)(data->pre_data); errval = execvp_noalloc(data->buf, argv[0], argv); diff -puN arch/um/os-Linux/main.c~uml-delete-unused-code arch/um/os-Linux/main.c --- a/arch/um/os-Linux/main.c~uml-delete-unused-code +++ a/arch/um/os-Linux/main.c @@ -25,12 +25,7 @@ #include "os.h" #include "um_malloc.h" -/* Set in set_stklim, which is called from main and __wrap_malloc. - * __wrap_malloc only calls it if main hasn't started. - */ -unsigned long stacksizelim; - -/* Set in main */ +/* Set in main, unchanged thereafter */ char *linux_prog; #define PGD_BOUND (4 * 1024 * 1024) @@ -52,7 +47,6 @@ static void set_stklim(void) exit(1); } } - stacksizelim = (lim.rlim_cur + PGD_BOUND - 1) & ~(PGD_BOUND - 1); } static __init void do_uml_initcalls(void) diff -puN arch/um/sys-i386/bugs.c~uml-delete-unused-code arch/um/sys-i386/bugs.c --- a/arch/um/sys-i386/bugs.c~uml-delete-unused-code +++ a/arch/um/sys-i386/bugs.c @@ -79,29 +79,6 @@ static int find_cpuinfo_line(int fd, cha return(0); } -int cpu_feature(char *what, char *buf, int len) -{ - int fd, ret = 0; - - fd = os_open_file("/proc/cpuinfo", of_read(OPENFLAGS()), 0); - if(fd < 0){ - printk("Couldn't open /proc/cpuinfo, err = %d\n", -fd); - return(0); - } - - if(!find_cpuinfo_line(fd, what, buf, len)){ - printk("Couldn't find '%s' line in /proc/cpuinfo\n", what); - goto out_close; - } - - token(fd, buf, len, '\n'); - ret = 1; - - out_close: - os_close_file(fd); - return(ret); -} - static int check_cpu_flag(char *feature, int *have_it) { char buf[MAXTOKEN], c; diff -puN arch/um/sys-x86_64/bugs.c~uml-delete-unused-code arch/um/sys-x86_64/bugs.c --- a/arch/um/sys-x86_64/bugs.c~uml-delete-unused-code +++ a/arch/um/sys-x86_64/bugs.c @@ -88,29 +88,6 @@ static int find_cpuinfo_line(int fd, cha return(0); } -int cpu_feature(char *what, char *buf, int len) -{ - int fd, ret = 0; - - fd = os_open_file("/proc/cpuinfo", of_read(OPENFLAGS()), 0); - if(fd < 0){ - printk("Couldn't open /proc/cpuinfo, err = %d\n", -fd); - return(0); - } - - if(!find_cpuinfo_line(fd, what, buf, len)){ - printk("Couldn't find '%s' line in /proc/cpuinfo\n", what); - goto out_close; - } - - token(fd, buf, len, '\n'); - ret = 1; - - out_close: - os_close_file(fd); - return(ret); -} - /* Overrides for Emacs so that we follow Linus's tabbing style. * Emacs will notice this stuff at the end of the file and automatically * adjust the settings for this buffer only.
