kernel: remove CONFIG_USE_GENERIC_SMP_HELPERS

2013-11-15T00:32:22Z

We've switched over every architecture that supports SMP to it, so remove the new useless config variable. Signed-off-by: Christoph Hellwig Cc: Jan Kara Cc: Jens Axboe Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Architectures which support CONFIG_PARPORT_PC should select ARCH_MIGHT_HAVE_PC_PARPORT. Signed-off-by: Mark Salter CC: "James E.J. Bottomley" CC: Helge Deller CC: linux-parisc@vger.kernel.org

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52Z

After the last architecture switched to generic hard irqs the config options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code for !CONFIG_GENERIC_HARDIRQS can be removed. Signed-off-by: Martin Schwidefsky

Merge branch 'kconfig-diet' from Dave Hansen

2013-07-04T18:25:51Z

Merge Kconfig menu diet patches from Dave Hansen: "I think the "Kernel Hacking" menu has gotten a bit out of hand. It is over 120 lines long on my system with everything enabled and options are scattered around it haphazardly. http://sr71.net/~dave/linux/kconfig-horror.png Let's try to introduce some sanity. This set takes that 120 lines down to 55 and makes it vastly easier to find some things. It's a start. This set stands on its own, but there is plenty of room for follow-up patches. The arch-specific debug options still end up getting stuck in the top-level "kernel hacking" menu. OPTIMIZE_INLINING, for instance, could obviously go in to the "compiler options" menu, but the fact that it is defined in arch/ in a separate Kconfig file keeps it on its own for the moment. The Signed-off-by's in here look funky. I changed employers while working on this set, so I have signoffs from both email addresses" * emailed patches from Dave Hansen : hang and lockup detection menu kconfig: consolidate printk options group locking debugging options consolidate compilation option configs consolidate runtime testing configs order memory debugging Kconfig options consolidate per-arch stack overflow debugging options

consolidate per-arch stack overflow debugging options

2013-07-04T18:25:39Z

Original posting: http://lkml.kernel.org/r/20121214184202.F54094D9@kernel.stglabs.ibm.com Several architectures have similar stack debugging config options. They all pretty much do the same thing, some with slightly differing help text. This patch changes the architectures to instead enable a Kconfig boolean, and then use that boolean in the generic Kconfig.debug to present the actual menu option. This removes a bunch of duplication and adds consistency across arches. Signed-off-by: Dave Hansen Reviewed-by: H.

Finally eradicate CONFIG_HOTPLUG

2013-06-03T21:20:18Z

Ever since commit 45f035ab9b8f ("CONFIG_HOTPLUG should be always on"), it has been basically impossible to build a kernel with CONFIG_HOTPLUG turned off. Remove all the remaining references to it.

parisc: implement irq stacks - part 2 (v2)

2013-05-11T19:10:15Z

This patch fixes few build issues which were introduced with the last irq stack patch, e.g. the combination of stack overflow check and irq stack. Furthermore we now do proper locking and change the irq bh handler to use the irq stack as well. In /proc/interrupts one now can monitor how huge the irq stack has grown and how often it was preferred over the kernel stack. IRQ stacks are now enabled by default just to make sure that we not overflow the kernel stack by accident. Signed-off-by: Helge Deller

parisc: implement irq stacks

2013-05-07T20:30:35Z

Default kernel stack size on parisc is 16k. During tests we found that the kernel stack can easily grow beyond 13k, which leaves 3k left for irq processing. This patch adds the possibility to activate an additional stack of 16k per CPU which is being used during irq processing. This implementation does not yet uses this irq stack for the irq bh handler. The assembler code for call_on_stack was heavily cleaned up by John David Anglin. CC: John David Anglin Signed-off-by: Helge Deller
