* CRIS: UAPI: fix elf.h exportRabin Vincent2015-09-051-84/+0
| | | | | | | | | 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 <rabin@rab.in> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
* CRIS: don't make asm/elf.h depend on asm/user.hRabin Vincent2015-09-051-2/+3
| | | | | | | | 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 <rabin@rab.in> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
* CRIS: UAPI: fix ptrace.hRabin Vincent2015-09-051-118/+0
| | | | | | | | | | 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.

* CRISv10: remove redundant macros from system.hRabin Vincent2015-03-251-8/+0

* cris: remove deprecated IRQF_DISABLEDMichael Opdenacker2014-01-081-3/+3
| | | | | | | | | | | | | | | | | | This patch proposes to remove the IRQF_DISABLED flag from CRIS architecture code. It's a NOOP since 2.6.35 and it will be removed one day. Comments mentioning IRQF_DISABLED are also updated, knowing that all interrupts are now "fast interrupts", their handlers running with interrupts disabled. Don't hesitate to let me know if you have other ways of rephrasing the comments! This is an update for 3.11 of a patch already sent for 3.10 Signed-off-by: Michael Opdenacker <michael.opdenacker@free-electrons.com> Signed-off-by: Jesper Nilsson <jespern@axis.com>
* sched: Rename sched.c as sched/core.c in comments and DocumentationViresh Kumar2013-06-191-1/+1
| | | | | | | | | | | | | | | | | Most of the stuff from kernel/sched.c was moved to kernel/sched/core.c long time back and the comments/Documentation never got updated. I figured it out when I was going through sched-domains.txt and so thought of fixing it globally. I haven't crossed check if the stuff that is referenced in sched/core.c by all these files is still present and hasn't changed as that wasn't the motive behind this patch.

* UAPI: Fix up empty files in arch/cris/David Howells2012-12-201-0/+1
| | | | | | | | | | | | | | | | | | Fix up three empty files in arch/cris/ by sticking placeholder comments in there to prevent the patch program from deleting them. I decided not to delete the arch-v*/Kbuild files as it's possibly someone might want to use them for genhdr-y lines in the future, but they could be deleted and the pointer lines removed from asm/Kbuild. The uapi/arch-v*/Kbuild files ought to be uneffected by such a change. asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in uapi/asm/swab.h. The latter, however, is exported by Kbuild.asm. This needs to be applied after the CRIS UAPI disintegration patch.

* Fix IRQ flag handling namingDavid Howells2010-10-072-16/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.
