eea6f62bc2 kbuild: rpm-pkg: use kernel-install as a fallback for new-kernel-pkg
The new-kernel-pkg script is only present when grubby is installed, but it
may not always be the case. So if the script isn't present, attempt to use
the kernel-install script as a fallback instead.

The problem here is, at btree_read_extent_buffer_pages() we don't have
acquired read/write lock on that extent buffer, only basic info like
level/bytenr is reliable.

So race condition leads to such false alert.

However in current call site, it's impossible to acquire proper lock
without race window.
To fix the problem, we only verify first key for committed tree blocks
(whose generation is no larger than fs_info->last_trans_committed), so
the content of such tree blocks will not change and there is no need to
get read/write lock.

81b654c273 powerpc/64s: Fix CPU_FTRS_ALWAYS vs DT CPU features
The cpu_has_feature() mechanism has an optimisation where at build
time we construct a mask of the CPU feature bits that will always be
true for the given .config, based on the platform/bitness/etc. that we
are building for.

That is incompatible with DT CPU features, where the set of CPU
features is dependent on feature flags that are given to us by
firmware.

The result is that some feature bits can not be *disabled* by DT CPU
features. Or more accurately, they can be disabled but they will still
appear in the ALWAYS mask, meaning cpu_has_feature() will always
return true for them.

In the past this hasn't really been a problem because on Book3S
64 (where we support DT CPU features), the set of ALWAYS bits has been
very small. That was because we always built for POWER4 and later,
meaning the set of common bits was small.

The only bit that could be cleared by DT CPU features that was also in
the ALWAYS mask was CPU_FTR_NODSISRALIGN, and that was only used in
the alignment handler to create a fake DSISR. That code was itself
deleted in 31bfdb036f ("powerpc: Use instruction emulation
infrastructure to handle alignment faults") (Sep 2017).

However the set of ALWAYS features changed with the recent commit
db5ae1c155 ("powerpc/64s: Refine feature sets for little endian
builds") which restricted the set of feature flags when building
little endian to Power7 or later. That caused the ALWAYS mask to
become much larger for little endian builds.

The result is that the following feature bits can currently not
be *disabled* by DT CPU features:

  CPU_FTR_REAL_LE, CPU_FTR_MMCRA, CPU_FTR_CTRL, CPU_FTR_SMT,
  CPU_FTR_PURR, CPU_FTR_SPURR, CPU_FTR_DSCR, CPU_FTR_PKEY,
  CPU_FTR_VMX_COPY, CPU_FTR_CFAR, CPU_FTR_HAS_PPR.

To fix it we need to mask the set of ALWAYS features with the base set
of DT CPU features, ie. the features that are always enabled by DT CPU
features. That way there are no bits in the ALWAYS mask that are not
also always set by DT CPU features.

The test which ensures that the DMI type 1 structure is long enough

bf9c7e3d79 arch/sh: pcie-sh7786: handle non-zero DMA offset
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.

79e1c5e70b arch/sh: pcie-sh7786: adjust the memory mapping
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.

5da1bb96dc arch/sh: pcie-sh7786: adjust PCI MEM and IO regions
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.

d62e9bf5dd arch/sh: pcie-sh7786: exclude unusable PCI MEM areas
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.

7dd7f69809 arch/sh: pcie-sh7786: mark unavailable PCI resource as disabled
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.

Also, in register_pci_controller(), we travel through all resources to

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.

ce88313069 arch/sh: make the DMA mapping operations observe dev->dma_pfn_offset
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.

bc05aa6e13 arch/sh: add sh7786_mm_sel() function
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.

96a598996f sh: fix debug trap failure to process signals before return to user
When responding to a debug trap (breakpoint) in userspace, the
kernel's trap handler raised SIGTRAP but returned from the trap via a
code path that ignored pending signals, resulting in an infinite loop
re-executing the trapping instruction.

eb6b6930a7 sh: fix memory corruption of unflattened device tree
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.

9b7e30ab97 sh: fix futex FUTEX_OP_SET op on userspace addresses
Commit 00b73d8d1b ("sh: add working futex atomic ops on userspace
addresses for smp") changed the futex_atomic_op_inuser function to
use a loop. In case of the FUTEX_OP_SET op with a userspace address
containing a value different of 0, this loop is an endless loop.

Fix that by loading the value of oldval from the userspace before doing
the cmpxchg op, also for the FUTEX_OP_SET case.

b2f3f5920d drm/amd/display: Fix regamma not affecting full-intensity color values
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.
