mn10300: Remove the architecture

2018-03-09T22:19:56Z

Remove the MN10300 arch as the hardware is defunct. Suggested-by: Arnd Bergmann Signed-off-by: David Howells cc: Masahiro Yamada cc: linux-am33-list@redhat.com Signed-off-by: Arnd Bergmann

sched/headers: Prepare to remove the dependency from

2017-03-02T07:42:37Z

Update code that relied on sched.h including various MM types for them. This will allow us to remove the include from . Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:35Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

mm: add new mmgrab() helper

2017-02-28T02:43:48Z

Apart from adding the helper function itself, the rest of the kernel is converted mechanically using: git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_count);/mmgrab\(\1\);/' git grep -l 'atomic_inc.*mm_count' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_count);/mmgrab\(\&\1\);/' This is needed for a later patch that hooks into the helper, but might be a worthwhile cleanup on its own.

arch/hotplug: Call into idle with a proper state

2016-03-01T19:36:57Z

Let the non boot cpus call into idle with the corresponding hotplug state, so the hotplug core can handle the further bringup. That's a first step to convert the boot side of the hotplugged cpus to do all the synchronization with the other side through the state machine. For now it'll only start the hotplug thread and kick the full bringup of the cpu. Signed-off-by: Thomas Gleixner Cc: linux-arch@vger.kernel.org Cc: Rik van Riel Cc: Rafael Wysocki Cc: "Srivatsa S.

mn10300: Remove deprecated IRQF_DISABLED

2014-03-04T20:47:51Z

This patch removes the IRQF_DISABLED flag from mn10300 architecture code. It's a NOOP since 2.6.35 and it will be removed one day.

mn10300: Use generic idle loop

2013-04-08T15:39:27Z

default_idle() boils down to safe_halt() and the other option is idle polling. Use the core functionality.

ARCH: drivers remove __dev* attributes.

2013-01-03T23:57:13Z

This fixes up all of the smaller arches that had __dev* markings for their platform-specific drivers. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

MN10300: cleanup IRQ affinity setting

2012-12-12T15:46:14Z

The irq_set_affinity handler for the mn10300 cpu pic had some hard-coded IRQs which were not to be migrated from one cpu to another. This patch cleans those up by using a combination of IRQF_NOBALANCING and specialized irq chips with no irq_set_affinity handler. This maintains the previous behavior by using generic IRQ interfaces rather than hard coding IRQ numbers in the default irq_set_affinity handler.
