cris: Remove unnecessary of_platform_populate with default match table

2016-06-23T20:00:22Z

After patch "of/platform: Add common method to populate default bus", it is possible for arch code to remove unnecessary callers of of_platform_populate with default match table. Acked-by: Jesper Nilsson Cc: Mikael Starvik Cc: Jesper Nilsson Signed-off-by: Kefeng Wang Signed-off-by: Rob Herring

cris: Fix section mismatches in architecture startup code

2015-12-15T13:03:19Z

Section mismatches can now result in build failures. As result, cris:allnoconfig fails to build as follows. WARNING: modpost: Found 7 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' FATAL: modpost: Section mismatches detected. Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them. Part of the problem is that references from .text to .init.text are not permitted, and such references are used in cris startup code. Since references from .head.text to .init.text are permitted, move cris startup code to a new section .head.text. Signed-off-by: Guenter Roeck Signed-off-by: Jesper Nilsson

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

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
