CRIS v32: remove old GPIO and LEDs code

2015-11-02T19:03:05Z

Since we now have a gpiolib driver, remove this code: The gpio-etraxfs driver (along with things like gpio-keys-polled for polling support) replaces the GIO driver implementations in mach-a3 and mach-fs. The various generic external chip drivers replace the "virtual gpio" parts. The generic gpio-leds driver replaces the LED handling. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS v32: increase NR_IRQS

2015-11-02T19:03:04Z

Increase NR_IQRS so we can fit in GPIO interrupts. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: UAPI: fix elf.h export

2015-09-04T22:33:25Z

CRIS userspace (uClibc for one) expects asm/elf.h to be exported but this header appears to have gone missing at some point. Move it to uapi/ and export it. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: don't make asm/elf.h depend on asm/user.h

2015-09-04T22:33:25Z

We're going to export asm/elf.h; remove its dependencies on the non-exported asm/user.h and the unused asm/system.h include. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: UAPI: fix ptrace.h

2015-09-04T22:33:25Z

The exported ptrace.h header on CRIS references an "arch" directory which does not exist. Fix this by having the variants in the same directory and including them conditionally, similar to other architectures. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRISv32: add unreachable() to BUG()

2015-09-04T22:33:24Z

Add an unreachable() in the BUG() implementations, to get rid of several warnings similar to the one below: kernel/sched/core.c: In function 'pick_next_task': kernel/sched/core.c:2690:1: warning: control reaches end of non-void function [-Wreturn-type] Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: use generic atomic.h

2015-03-25T09:57:03Z

CRIS can use asm-generic's atomic.h. Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

CRIS: remove SMP code

2015-03-25T09:55:10Z

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: don't enable irqs in INIT_THREAD

2015-03-25T09:54:06Z

INIT_THREAD enables interrupts in the thread_struct's saved flags. This means that interrupts get enabled in the middle of context_switch() while switching to new tasks that get forked off the init task during boot. Don't do this. Fixes the following splat on boot with spinlock debugging on: BUG: spinlock cpu recursion on CPU#0, swapper/2 lock: runqueues+0x0/0x47c, .magic: dead4ead, .owner: swapper/0, .owner_cpu: 0 CPU: 0 PID: 2 Comm: swapper Not tainted 3.19.0-08796-ga747b55 #285 Call Trace: [] spin_bug+0x2a/0x36 [] do_raw_spin_lock+0xa2/0x126 [] _raw_spin_lock+0x20/0x2a [] scheduler_tick+0x22/0x76 [] update_process_times+0x5e/0x72 [] timer_interrupt+0x4e/0x6a [] handle_irq_event_percpu+0x54/0xf2 [] handle_irq_event+0x50/0x74 [] handle_simple_irq+0x6c/0xbe [] generic_handle_irq+0x2a/0x36 [] do_IRQ+0x38/0x84 [] crisv32_do_IRQ+0x54/0x60 [] IRQ0x4b_interrupt+0x34/0x3c [] __schedule+0x24a/0x532 [] ret_from_kernel_thread+0x0/0x14 Signed-off-by: Rabin Vincent Signed-off-by: Jesper Nilsson

cris: drop _PAGE_FILE and pte_file()-related helpers

2015-02-10T22:30:32Z

We've replaced remap_file_pages(2) implementation with emulation. Nobody creates non-linear mapping anymore. Signed-off-by: Kirill A. Shutemov Cc: Mikael Starvik Cc: Jesper Nilsson Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
