Pull arch/cris updates from Jesper Nilsson: "Some much needed love for the CRIS-port. There's a bunch of changes this time, giving the CRISv32 port a bit of modern makeover with device-tree, irq domain and gpiolib support, and more switchover to generic frameworks. Some small fixes and removal of the theoretical SMP support brings up the rear" * tag 'cris-for-4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/jesper/cris: cris: fix integer overflow in ELF_ET_DYN_BASE CRISv32: use GENERIC_SCHED_CLOCK CRISv32: use MMIO clocksource CRISv32: use generic clockevents CRIS: use generic headers via Kbuild CRIS: use generic cmpxchg.h CRIS: use generic atomic.h CRIS: use generic atomic bitops CRISv10: remove redundant macros from system.h CRIS: remove SMP code CRISv32: don't enable irqs in INIT_THREAD CRISv32: handle multiple signals CRISv32: prevent bogus restarts on sigreturn CRISv32: don't attempt syscall restart on irq exit Add binding documentation for CRIS CRIS: add Axis 88 board device tree CRISv32: add device tree support CRISv32: add irq domains support CRIS: enable GPIOLIB

cris fasttimer: remove use of seq_printf return value

2015-04-15T23:35:25+00:00

The seq_printf return value, because it's frequently misused, will eventually be converted to void.

CRISv32: use GENERIC_SCHED_CLOCK

2015-03-25T10:03:41+00:00

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: use MMIO clocksource

2015-03-25T10:03:40+00:00

Use a generic MMIO clocksource and get rid of some lines of code. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: use generic clockevents

2015-03-25T10:03:40+00:00

Implement a oneshot-capable clockevents device so we get support for things like hrtimers and NOHZ. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: remove SMP code

2015-03-25T09:55:10+00:00

The CRIS SMP code cannot be built since there is no (and appears to never have been) a CONFIG_SMP Kconfig option in arch/cris/. Remove it. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: handle multiple signals

2015-03-25T09:53:54+00:00

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
