powerpc: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

powerpc/rtas: arch-wide function token lookup conversions
With the tokens for all implemented RTAS functions now available via rtas_function_token(), which is optimal and safe for arbitrary contexts, there is no need to use rtas_token() or cache its result.
Most conversions are trivial, but a few are worth describing in more detail:
* Error injection token comparisons for lockdown purposes are consolidated into a simple predicate: token_is_restricted_errinjct().
* A couple of special cases in block_rtas_call() do not use rtas_token() but perform string comparisons against names in the function table. These are converted to compare against token values instead, which is logically equivalent but less expensive.
* The lookup for the ibm,os-term token can be deferred until needed, instead of caching it at boot to avoid device tree traversal during panic.
* Since rtas_function_token() accesses a read-only data structure without taking any locks, xmon's lookup of set-indicator can be performed as needed instead of cached at startup.

powerpc/pci: Move PHB discovery for PCI_DN using platforms
Make powernv, pseries, powermac and maple use ppc_mc.discover_phbs. These platforms need to be done together because they all depend on pci_dn's being created from the DT. The pci_dn contains a pointer to the relevant pci_controller so they need to be created after the pci_controller structures are available, but before PCI devices are scanned. Currently this ordering is provided by initcalls and the sequence is:
1. PHBs are discovered (setup_arch) (early boot, pre-initcalls) 2. pci_dn are created from the unflattended DT (core initcall) 3. PHBs are scanned pcibios_init() (subsys initcall)
The new ppc_md.discover_phbs() function is also a core_initcall so we can't guarantee ordering between the creation of pci_controllers and the creation of pci_dn's which require a pci_controller. We could use the postcore, or core_sync initcall levels, but it's cleaner to just move the pci_dn setup into the per-PHB inits which occur inside of .discover_phb() for these platforms. This brings the boot-time path in line with the PHB hotplug path that is used for pseries DLPAR operations too.

mm: don't include asm/pgtable.h if linux/mm.h is already included
Patch series "mm: consolidate definitions of page table accessors", v2.
The low level page table accessors (pXY_index(), pXY_offset()) are duplicated across all architectures and sometimes more than once. For instance, we have 31 definition of pgd_offset() for 25 supported architectures.
Most of these definitions are actually identical and typically it boils down to, e.g.
static inline unsigned long pmd_index(unsigned long address) { return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1); }
static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address) { return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address); }
These definitions can be shared among 90% of the arches provided XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.
For architectures that really need a custom version there is always possibility to override the generic version with the usual ifdefs magic.
These patches introduce include/linux/pgtable.h that replaces include/asm-generic/pgtable.h and add the definitions of the page table accessors to the new header.
This patch (of 12):
The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the functions involving page table manipulations, e.g. pte_alloc() and pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h> in the files that include <linux/mm.h>.
The include statements in such cases are remove with a simple loop:
for f in $(git grep -l "include <linux/mm.h>") ; do sed -i -e '/include <asm\/pgtable.h>/ d' $f done

powerpc/maple: Fix declaration made after definition
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.

powerpc/dart: Use a cachable DART
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.

If a pci_controller_ops struct is provided to iommu_init_early_dart, populate that with the DMA setup ops, rather than ppc_md. If NULL is provided, populate ppc_md as before.
This also patches the call sites for Maple and Power Mac to pass NULL, so existing behaviour is preserved.
The benefit of making this optional is that it means we don't have to change dart, Maple and Power Mac over to the controller_ops system in one fell swoop.

powerpc: Convert power off logic to pm_power_off
The generic Linux framework to power off the machine is a function pointer called pm_power_off. The trick about this pointer is that device drivers can potentially implement it rather than board files.
Today on powerpc we set pm_power_off to invoke our generic full machine power off logic which then calls ppc_md.power_off to invoke machine specific power off.
However, when we want to add a power off GPIO via the "gpio-poweroff" driver, this card house falls apart. That driver only registers itself if pm_power_off is NULL to ensure it doesn't override board specific logic. However, since we always set pm_power_off to the generic power off logic (which will just not power off the machine if no ppc_md.power_off call is implemented), we can't implement power off via the generic GPIO power off driver.
To fix this up, let's get rid of the ppc_md.power_off logic and just always use pm_power_off as was intended. Then individual drivers such as the GPIO power off driver can implement power off logic via that function pointer.
With this patch set applied and a few patches on top of QEMU that implement a power off GPIO on the virt e500 machine, I can successfully turn off my virtual machine after halt.

powerpc/mpic: Remove duplicate MPIC_WANTS_RESET flag
There are two separate flags controlling whether or not the MPIC is reset during initialization, which is completely unnecessary, and only one of them can be specified in the device tree.
Also, most platforms in-tree right now do actually want to reset the MPIC during initialization anyways, which means lots of duplicate code passing the MPIC_WANTS_RESET flag.
Fix all of the callers which currently do not pass the MPIC_WANTS_RESET flag to pass the MPIC_NO_RESET flag, then remove the MPIC_WANTS_RESET flag and make the code reset the MPIC by default.
