cris: Drop reference to get_cmos_time()

2015-11-02T19:03:05Z

Function get_cmos_time() was removed with commit 657926a83df9 ("cris: time: Cleanup of persistent clock stuff"). The remaining reference to it may cause the following build error. arch/cris/kernel/built-in.o:(___ksymtab+get_cmos_time+0x0): undefined reference to `get_cmos_time' Makefile:946: recipe for target 'vmlinux' failed Fixes: 657926a83df9 ("cris: time: Cleanup of persistent clock stuff") Cc: Xunlei Pang Cc: Rabin Vincent Signed-off-by: Guenter Roeck Signed-off-by: Jesper Nilsson

cris: time: Cleanup of persistent clock stuff

2015-11-02T19:03:05Z

- Remove update_persistent_clock(), as it does nothing now. - Remove read_persistent_clock(), let it fall back to the weak version. Cc: Mikael Starvik Cc: John Stultz Cc: Arnd Bergmann Signed-off-by: Xunlei Pang Acked-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: add STACKTRACE_SUPPORT

2015-09-04T22:56:50Z

Add stacktrace support, which is required for lockdep and tracing. The stack tracing simply looks at all kernel text symbols found on the stack, similar to the trap stack dumping code, which can also be converted to use this. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: add support for irqflags tracing

2015-09-04T22:56:49Z

Add support irqflags tracing, which is required for things like lockdep and ftrace. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: use GENERIC_SCHED_CLOCK

2015-03-25T10:03:41Z

Provide a fast sched clock using the free-running timer and the generic sched_clock infrastructure. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: handle multiple signals

2015-03-25T09:53:54Z

Al Viro noted that CRIS fails to handle multiple signals. This fixes the problem for CRISv32 by making it use a C work_pending handling loop similar to the ARM implementation in 0a267fa6a15d41c ("ARM: 7472/1: pull all work_pending logics into C function"). This also happens to fixes the warnings which currently trigger on CRISv32 due to do_signal() being called with interrupts disabled. Test case (should die of the SIGSEGV which gets raised when setting up the stack for SIGALRM, but instead reaches and executes the _exit(1)): #include #include #include #include static void handler(int sig) { } int main(int argc, char *argv[]) { int ret; struct itimerval t1 = { .it_value = {1} }; stack_t ss = { .ss_sp = NULL, .ss_size = SIGSTKSZ, }; struct sigaction action = { .sa_handler = handler, .sa_flags = SA_ONSTACK, }; ret = sigaltstack(&ss, NULL); if (ret < 0) err(1, "sigaltstack"); sigaction(SIGALRM, &action, NULL); setitimer(ITIMER_REAL, &t1, NULL); pause(); _exit(1); return 0; } Reported-by: Al Viro Link: http://lkml.kernel.org/r/20121208074429.GC4939@ZenIV.linux.org.uk Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: add device tree support

2015-03-25T08:49:48Z

Add support for booting CRISv32 with a built-in device tree. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: Export csum_partial_copy_nocheck

2015-01-29T09:10:08Z

Allows that symbol to be used in modules, and fixes the following on allmodconfig: ERROR: "csum_partial_copy_nocheck" [net/ipv6/ipv6.ko] undefined! Signed-off-by: Jesper Nilsson

module: remove mod arg from module_free, rename module_memfree().

2015-01-20T01:08:33Z

Nothing needs the module pointer any more, and the next patch will call it from RCU, where the module itself might no longer exist. Removing the arg is the safest approach. This just codifies the use of the module_alloc/module_free pattern which ftrace and bpf use.
