powerpc/maple: Fix declaration made after definition

2020-03-25T01:09:48Z

When building ppc64 defconfig, Clang errors (trimmed for brevity): arch/powerpc/platforms/maple/setup.c:365:1: error: attribute declaration must precede definition [-Werror,-Wignored-attributes] machine_device_initcall(maple, maple_cpc925_edac_setup); ^ machine_device_initcall expands to __define_machine_initcall, which in turn has the macro machine_is used in it, which declares mach_##name with an __attribute__((weak)). define_machine actually defines mach_##name, which in this file happens before the declaration, hence the warning. To fix this, move define_machine after machine_device_initcall so that the declaration occurs before the definition, which matches how machine_device_initcall and define_machine work throughout arch/powerpc. While we're here, remove some spaces before tabs.

Pull powerpc updates from Michael Ellerman: "A pretty small batch for us, and apologies for it being a bit late, I wanted to sneak Christophe's user_access_begin() series in. Summary: - Implement user_access_begin() and friends for our platforms that support controlling kernel access to userspace. - Enable CONFIG_VMAP_STACK on 32-bit Book3S and 8xx. - Some tweaks to our pseries IOMMU code to allow SVMs ("secure" virtual machines) to use the IOMMU. - Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 32-bit VDSO, and some other improvements. - A series to use the PCI hotplug framework to control opencapi card's so that they can be reset and re-read after flashing a new FPGA image. As well as other minor fixes and improvements as usual.

powerpc/64: Move 64-bit probe_machine() to later in the boot process

2016-07-21T08:59:22Z

We no long need the machine type that early, so we can move probe_machine() to after the device-tree has been expanded. This will allow further consolidation. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman

powerpc/dart: Use a cachable DART

2016-07-21T08:55:54Z

Instead of punching a hole in the linear mapping, just use normal cachable memory, and apply the flush sequence documented in the CPC625 (aka U3) user manual. This allows us to remove quite a bit of code related to the early allocation of the DART and the hole in the linear mapping. We can also get rid of the copy of the DART for suspend/resume as the original memory can just be saved/restored now, as long as we properly sync the caches.
