Add power domain control support for the r8a7779 SoC V2.
This adds support for 4 power domains for I/O Devices
together with code that can be used for CPU cores as well.
The only out of the ordinary experience is the need for
ioremap() of SYSC registers. Because of that we need to
execute some init function before setting up the domains.

do_notify_resume() can trigger the freezer via the try_to_freeze() path
(both explicitly through a redundant call in do_signal() or via
get_signal_to_deliver()). That IRQs were disabled across this callsite
became apparent with the might_sleep() introduction in try_to_freeze() by
Tejun in a0acae0e88, resulting in:
BUG: sleeping function called from invalid context at include/linux/freezer.h:45

atomic64_read() doesn't actually write anything (as far as the C
environment is concerned... the CPU does actually write but that's an
implementation quirk), so it should take a const pointer.
This does NOT mean that it is safe to use atomic64_read() on an object
in readonly storage (it will trap!)

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

This is where the really nasty conflicts in the samsung platform
start, due to some files getting moved around and combined in the
'restart' branch that has already gone into mainline through
Russell's tree.

Some SoCs have a timer block enable controlled through the DSCR registers.
There is a problem in the timer64 driver initialization where the code
accesses a timer register to get the divisor used to calculate timer clock
rate. If the timer block has not been enabled when this register read takes
place, an exception is generated. This patch makes sure that the timer block
is enabled before accessing the registers.

This reverts commit d5e553d6e0, which

This moves the #include <asm/asm-offsets.h> to <asm/syscall.h>, which

x86: Add NumaChip support
x86: Add x86_init platform override to fix up NUMA core numbering
x86: Make flat_init_apic_ldr() available
This factors out the AMD native MMCONFIG discovery so we can use it
outside amd_bus.c.
amd_bus.c reads AMD MSRs so it can remove the MMCONFIG area from the
PCI resources. We may also need the MMCONFIG information to work
around BIOS defects in the ACPI MCFG table.

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
fixups. This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.
This arch was unusual because it filled in bus->resource[0..3] in
pcibios_init(), then overwrote them, applied io_space.offset and
checked for unset resources in pcibios_fixup_bus(). I moved all of
that to a new pci_controller_apertures() that we can use before
scanning the root bus.

x86 has two kinds of PCI root bus scanning:
(1) ACPI-based, using _CRS resources. This used pci_create_bus(), not
pci_scan_bus(), because ACPI hotplug needed to split the
pci_bus_add_devices() into a separate host bridge .start() method.
This patch parses the _CRS resources earlier, so we can build a list of
resources and pass it to pci_create_root_bus().
Note that as before, we parse the _CRS even if we aren't going to use
it so we can print it for debugging purposes.
(2) All other, which used either default resources (ioport_resource and
iomem_resource) or information read from the hardware via amd_bus.c or
similar. This used pci_scan_bus().
This patch converts x86_pci_root_bus_res_quirks() (previously called
from pcibios_fixup_bus()) to x86_pci_root_bus_resources(), which builds
a list of resources before we call pci_scan_root_bus().
We also use x86_pci_root_bus_resources() if we have ACPI but are
ignoring _CRS.

This doesn't change any functionality, but it makes a subsequent patch
slightly simpler.
pci_scan_bus(NULL, ...) and pci_scan_bus_parented() are identical except
that pci_scan_bus() also calls pci_bus_add_devices():
pci_scan_bus_parented
pci_create_bus
pci_scan_child_bus
pci_scan_bus
pci_create_bus
pci_scan_child_bus
pci_bus_add_devices
All callers of pcibios_scan_root() call pci_bus_add_devices() explicitly,
and we don't pass a parent device, so we might as well use pci_scan_bus().

We currently read the CNB20LE aperture information in a PCI quirk,
which happens after we've already created the root bus. This patch
changes it to read the apertures earlier so we can create the root
bus with the correct resources.
I believe the CNB20LE lives at "pci 0000:00:00" based on

pci_scan_root_bus() also includes the pci_bus_add_devices() so we don't

The pci_bus_for_each_resource() iterator sets "res" itself, so there's

Note that peer root buses are scanned with pci_scan_bus() (which is now
deprecated), so they have the default ioport_resource and iomem_resource

incorrect, and I don't know how to discover the correct ones.

Commit 24d9b70b8c (x86: Use PCI method
for enabling AMD extended config space before MSR method) added a
message when IO access to PCI ECS was enabled via access to the NB_CFG
PCI register. This can lead to a bogus message like
[ 0.365177] Extended Config Space enabled on 0 nodes
which is misleading because IO ECS access is subsequently enabled for
AMD CPUs (that support this) by modifying the corresponding NB_CFG
MSR.
Furthermore it's not "Extended Config Space" that is enabled by this
register setting. It's the IO access that is enabled for extended
configruation space.
IMHO the ambiguous message needs to be cancelled.
