openrisc: fix CONFIG_UID16 setting

2015-07-17T23:39:52+00:00

openrisc-allnoconfig:

  kernel/uid16.c: In function 'SYSC_setgroups16':
  kernel/uid16.c:184:2: error: implicit declaration of function 'groups_alloc'
  kernel/uid16.c:184:13: warning: assignment makes pointer from integer without a cast

openrisc shouldn't be setting CONFIG_UID16 when CONFIG_MULTIUSER=n.

openrisc: Convert handle_IRQ to use __handle_domain_irq

2014-09-03T13:10:19+00:00

In order to limit code duplication, convert the architecture specific
handle_IRQ to use the generic __handle_domain_irq function.

irqchip: or1k-pic: Migrate from arch/openrisc/

2014-07-01T12:15:06+00:00

In addition to consolidating the or1k-pic with other interrupt
controllers, this makes OpenRISC less tied to its on-cpu
interrupt controller.

All or1k-pic specific parts are moved out of irq.c and into
drivers/irqchip/irq-or1k-pic.c

In that transition, the functionality have been divided into
three chip variants.
One that handles level triggered interrupts, one that handles edge
triggered interrupts and one that handles the interrupt
controller that is present in the or1200 OpenRISC cpu
implementation.

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP

2014-04-07T23:36:11+00:00

If the renamed symbol is defined lib/iomap.c implements ioport_map and
ioport_unmap and currently (nearly) all platforms define the port
accessor functions outb/inb and friend unconditionally.  So
HAS_IOPORT_MAP is the better name for this.

Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

The motivation for this change is to reintroduce a symbol HAS_IOPORT
that signals if outb/int et al are available.  I will address that at
least one merge window later though to keep surprises to a minimum and
catch new introductions of (HAS|NO)_IOPORT.

The changes in this commit were done using:

	$ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52+00:00

After the last architecture switched to generic hard irqs the config
options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code

arch: : Kconfig: add "kernel/Kconfig.freezer" to "arch//Kconfig"

2013-08-14T00:57:49+00:00

All architectures include "kernel/Kconfig.freezer" except three left, so
let them include it too, or 'allmodconfig' will report error.

The related errors: (with allmodconfig for openrisc):

consolidate per-arch stack overflow debugging options

2013-07-04T18:25:39+00:00

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.

Pull removal of GENERIC_GPIO from Grant Likely:
 "GENERIC_GPIO now synonymous with GPIOLIB.  There are no longer any
  valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
  is possible to do so which has been causing confusion and breakage.
  This branch does the work to completely eliminate GENERIC_GPIO."

Remove GENERIC_GPIO config option

2013-04-16T09:47:19+00:00

GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code
and all driver code has been switch to depend on GPIOLIB. It is thus
safe to have GENERIC_GPIO removed.
