On SuperH, the base of the physical memory might be different from
zero. In this case, PCI address zero will map to a non-zero physical
address. In order to make sure that the DMA mapping API takes care of
this DMA offset, we must fill in the dev->dma_pfn_offset field for PCI
devices. This gets done in the pcibios_bus_add_device() hook, called
for each new PCI device detected.
The dma_pfn_offset global variable is re-calculated for every PCI
controller available on the platform, but that's not an issue because
its value will each time be exactly the same, as it only depends on
the memory start address and memory size.

The code setting up the PCI -> SuperHighway mapping doesn't take into
account the fact that the address stored in PCIELARx must be aligned
with the size stored in PCIELAMRx.
For example, when your physical memory starts at 0x0800_0000 (128 MB),
a size of 64 MB or 128 MB is fine. However, if you have 256 MB of
memory, it doesn't work because the base address is not aligned on the
size.
In such situation, we have to round down the base address to make sure
it is aligned on the size of the area. For for a 0x0800_0000 base
address with 256 MB of memory, we will round down to 0x0, and extend
the size of the mapping to 512 MB.
This allows the mapping to work on platforms that have 256 MB of
RAM. The current setup would only work with 128 MB of RAM or less.

The current definition of the PCIe IO and MEM resources for SH7786
doesn't match what the datasheet says. For example, for PCIe0
0xfe100000 is advertised by the datasheet as a PCI IO region, while
0xfd000000 is advertised as a PCI MEM region. The code currently
inverts the two.
The SH4A_PCIEPARL and SH4A_PCIEPTCTLR registers allow to define the
base address and role of the different regions (including whether it's
a MEM or IO region). However, practical experience on a SH7786 shows
that if 0xfe100000 is used for LEL and 0xfd000000 for IO, a PCIe
device using two MEM BARs cannot be accessed at all. Simply using
0xfe100000 for IO and 0xfd000000 for MEM makes the PCIe device
accessible.
It is very likely that this was never seen because there are two other
PCI MEM region listed in the resources. However, for different
reasons, none of the two other MEM regions are usable on the specific
SH7786 platform the problem was encountered. Therefore, the last MEM
region at 0xfe100000 was used to place the BARs, making the device
non-functional.
This commit therefore adjusts those PCI MEM and IO resources
definitions so that they match what the datasheet says. They have only
been tested with PCIe 0.

Depending on the physical memory layout, some PCI MEM areas are not
usable. According to the SH7786 datasheet, the PCI MEM area from
1000_0000 to 13FF_FFFF is only usable if the physical memory layout
(in MMSELR) is 1, 2, 5 or 6. In all other configurations, this PCI MEM
area is not usable (because it overlaps with DRAM).
Therefore, this commit adjusts the PCI SH7786 initialization to mark
the relevant PCI resource as IORESOURCE_DISABLED if we can't use it.

Some PCI MEM resources are marked as IORESOURCE_MEM_32BIT, which means
they are only usable when the SH core runs in 32-bit mode. In 29-bit
mode, such memory regions are not usable.
The existing code for SH7786 properly skips such regions when
configuring the PCIe controller registers. However, because such
regions are still described in the resource array, the
pcibios_scanbus() function in the SuperH pci.c will register them to
the PCI core. Due to this, the PCI core will allocate MEM areas from
this resource, and assign BARs pointing to this area, even though it's
unusable.
In order to prevent this from happening, we mark such regions as
IORESOURCE_DISABLED, which tells the SuperH pci.c pcibios_scanbus()
function to skip them.
Note that we separate marking the region as disabled from skipping it,
because other regions will be marked as disabled in follow-up patches.

In pcibios_scanbus(), we provide to the PCI core the usable MEM and IO
regions using pci_add_resource_offset(). We travel through all
resources available in the "struct pci_channel".
Also, in register_pci_controller(), we travel through all resources to
request them, making sure they don't conflict with already requested
resources.
However, some resources may be disabled, in which case they should not
be requested nor provided to the PCI core.
In the current situation, none of the resources are disabled. However,
follow-up patches in this series will make some resources disabled,
making this preliminary change necessary.

Some devices may have a non-zero DMA offset, i.e an offset between the
DMA address and the physical address. Such an offset can be encoded
into the dma_pfn_offset field of "struct device", but the SuperH
implementation of the DMA mapping API does not observe this
information.
This commit fixes that by ensuring the DMA address is properly
calculated depending on this DMA offset.

The SH7786 has different physical memory layout configurations,
configurable through the MMSELR register. The configuration is
typically defined by the bootloader, so Linux generally doesn't care.
Except that depending on the configuration, some PCI MEM areas may or
may not be available. This commit adds a helper function that allows
to retrieve the current physical memory layout configuration. It will
be used in a following patch to exclude unusable PCI MEM areas during
the PCI initialization.

unflatten_device_tree() makes use of memblock allocation, and
therefore must be called before paging_init() migrates the memblock
allocation data to the bootmem framework. Otherwise the record of the
allocation for the expanded device tree will be lost, and will
eventually be clobbered when allocated for another use.

use a loop. In case of the FUTEX_OP_SET op with a userspace address

Hardware understands the regamma LUT as a piecewise linear function,
with points spaced exponentially along the range. We previously
programmed the LUT for range [2^-10, 2^0). This causes (normalized)
color values of 1 (=2^0) to miss the programmed LUT, and fall onto the
end region.
For DCE, the end region is extrapolated using a single (base, slope)
pair, using the max y-value from the last point in the curve as base.
This presents a problem, since this value affects all three color
channels. Scaling down the intensity of say - the blue regamma curve -
will not affect it's end region. This is especially noticiable when
using RedShift. It scales down the blue and green channels, but leaves
full-intensity colors unshifted.
Therefore, extend the range to cover [2^-10, 2^1) by programming another
hardware segment, containing only one point. That way, we won't be
hitting the end region.
Note that things are a bit different for DCN, since the end region can
be set per-channel.

Places where i_rwsem was called i_mutex, and adding i_rw_mutex.

Function rhashtable_walk_peek is problematic because there is no
guarantee that the glock previously returned still exists; when that key
is deleted, rhashtable_walk_peek can end up returning a different key,
which will cause an inconsistent glock dump. Fix this by keeping track
of the current glock in the seq file iterator functions instead.

Pull asm-generic fixes from Arnd Bergmann:
"I have one regression fix for a minor build problem after the
architecture removal series, plus a rework of the barriers in the
readl/writel functions, thanks to work by Sinan Kaya:
This started from a discussion on the linuxpcc and rdma mailing
lists[1]. To summarize, we decided that architectures are responsible
to serialize readl() and writel() accesses on a device MMIO space
relative to DMA performed by that device.
This series provides a pessimistic implementation of that behavior for
asm-generic/io.h, which is in turn used by a number of architectures
(h8300, microblaze, nios2, openrisc, s390, sparc, um, unicore32, and
xtensa). Some of those presumably need no extra barriers, or something
weaker than rmb()/wmb(), and they are advised to override the new
default for better performance.
For inb()/outb(), the same barriers are used, but architectures might
want to add another barrier to outb() here if that can guarantee
non-posted behavior (some architectures can, others cannot do that).
The readl_relaxed()/writel_relaxed() family of functions retains the
existing behavior with no extra barriers"

Pull more power management updates from Rafael Wysocki:
"These include one big-ticket item which is the rework of the idle loop
in order to prevent CPUs from spending too much time in shallow idle
states. It reduces idle power on some systems by 10% or more and may
improve performance of workloads in which the idle loop overhead
matters. This has been in the works for several weeks and it has been
tested and reviewed quite thoroughly.
Also included are changes that finalize the cpufreq cleanup moving
frequency table validation from drivers to the core, a few fixes and
cleanups of cpufreq drivers, a cpuidle documentation update and a PM
QoS core update to mark the expected switch fall-throughs in it.
Specifics:
- Rework the idle loop in order to prevent CPUs from spending too
much time in shallow idle states by making it stop the scheduler
tick before putting the CPU into an idle state only if the idle
duration predicted by the idle governor is long enough.
That required the code to be reordered to invoke the idle governor
before stopping the tick, among other things (Rafael Wysocki,
Frederic Weisbecker, Arnd Bergmann).
- Add the missing description of the residency sysfs attribute to the
cpuidle documentation (Prashanth Prakash).
- Finalize the cpufreq cleanup moving frequency table validation from
drivers to the core (Viresh Kumar).
- Fix a clock leak regression in the armada-37xx cpufreq driver
(Gregory Clement).
- Fix the initialization of the CPU performance data structures for
shared policies in the CPPC cpufreq driver (Shunyong Yang).
- Clean up the ti-cpufreq, intel_pstate and CPPC cpufreq drivers a
bit (Viresh Kumar, Rafael Wysocki).
- Mark the expected switch fall-throughs in the PM QoS core (Gustavo
Silva)"
