c365621838 clk: qcom: gcc-sdm660: Mark GPU CFG AHB clock as critical
This clock is critical for any access to the GPU: gating it will
crash the system when the GPU has been initialized (so, you cannot
gate it unless you deinit the Adreno completely).

So, to achieve a working state with GPU on, set the CLK_IS_CRITICAL
flag to this clock.

fe121bfe26 clk: qcom: gcc-sdm660: Mark MMSS NoC CFG AHB clock as critical
Similarly to MSM8998, any access to the MMSS depends on this clock.
Gating it will crash the system when RPMCC inits mmssnoc_axi_rpm_clk.

53748348a5 clk: qcom: gpucc-msm8998: Allow fabia gpupll0 rate setting
The GPU PLL0 is not a fixed PLL and the rate can be set on it:
this is necessary especially on boards which bootloader is setting
a very low rate on this PLL before booting Linux, which would be
unsuitable for postdividing to reach the maximum allowed Adreno GPU
frequency of 710MHz (or, actually, even 670MHz..) on this SoC.

To allow setting rates on the GPU PLL0, also define VCO boundaries
and set the CLK_SET_RATE_PARENT flag to the GPU PLL0 postdivider.

With this change, the Adreno GPU is now able to scale through all
the available frequencies.

a59c16c80b clk: qcom: gpucc-msm8998: Add resets, cxc, fix flags on gpu_gx_gdsc
The GPU GX GDSC has GPU_GX_BCR reset and gfx3d_clk CXC, as stated
on downstream kernels (and as verified upstream, because otherwise
random lockups happen).
Also, add PWRSTS_RET and NO_RET_PERIPH: also as found downstream,
and also as verified here, to avoid GPU related lockups it is
necessary to force retain mem, but *not* peripheral when enabling
this GDSC (and, of course, the inverse on disablement).

With this change, the GPU finally works flawlessly on my four
different MSM8998 devices from two different manufacturers.

785c02eb35 clk: qcom: gdsc: Implement NO_RET_PERIPH flag
In some rare occasions, we want to only set the RETAIN_MEM bit, but
not the RETAIN_PERIPH one: this is seen on at least SDM630/636/660's
GPU-GX GDSC, where unsetting and setting back the RETAIN_PERIPH bit
will generate chaos and panics during GPU suspend time (mainly, the
chaos is unaligned access).

For this reason, introduce a new NO_RET_PERIPH flag to the GDSC
driver to address this corner case.

68e1d106eb clk: qcom: mmcc-msm8998: Set bimc_smmu_gdsc always on
This GDSC enables (or cuts!) power to the Multimedia Subsystem IOMMU
(mmss smmu), which has bootloader pre-set secure contexts.
In the event of a complete power loss, the secure contexts will be
reset and the hypervisor will crash the SoC.

To prevent this, and get a working multimedia subsystem, set this
GDSC as always on.

fa92f3b093 clk: qcom: mmcc-msm8998: Add hardware clockgating registers to some clks
Hardware clock gating is supported on some of the clocks declared in

firmwares.
Add the HWCG registers where applicable to stop potential crashes.

This was verified on a smartphone shipped with a recent MSM8998
firmware, which will experience random crashes without this change.

292f75ecff clk: qcom: gcc-msm8998: Fix Alpha PLL type for all GPLLs
All of the GPLLs in the MSM8998 Global Clock Controller are Fabia PLLs
and not generic alphas: this was producing bad effects over the entire
clock tree of MSM8998, where any GPLL child clock was declaring a false
clock rate, due to their parent also showing the same.

The issue resides in the calculation of the clock rate for the specific
Alpha PLL type, where Fabia has a different register layout; switching
the MSM8998 GPLLs to the correct Alpha Fabia PLL type fixes the rate
(calculation) reading. While at it, also make these PLLs fixed since
their rate is supposed to *never* be changed while the system runs, as
this would surely crash the entire SoC.

Now all the children of all the PLLs are also complying with their
specified clock table and system stability is improved.

14e3e989f6 proc mountinfo: make splice available again
Since commit 36e2c7421f ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.

Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.

This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.

Joe Perches points out that the subsequent 'seq_putc()' should also be

Commit 660c486590 ("PCI: dwc: Set 32-bit DMA mask for MSI target address

for MSI message mapping, but for now it throws a warning on ret == 0, while
dma_set_mask() returns 0 in case of success.

Fix this by inverting the condition.

275e88b06a PCI: tegra: Fix host link initialization
Commit b9ac0f9dc8 ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common
code") broke enumeration of downstream devices on Tegra:

In non-working case (next-20201211):

  0001:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad2 (rev a1)
  0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
  0005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1)

In working case (v5.10-rc7):

  0001:00:00.0 PCI bridge: Molex Incorporated Device 1ad2 (rev a1)
  0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
  0005:00:00.0 PCI bridge: Molex Incorporated Device 1ad0 (rev a1)
  0005:01:00.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)
  0005:02:02.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)
  0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab)

The problem seems to be dw_pcie_setup_rc() is now called twice before and
after the link up handling. The fix is to move Tegra's link up handling to
.start_link() function like other DWC drivers. Tegra is a bit more
complicated than others as it re-inits the whole DWC controller to retry
the link. With this, the initialization ordering is restored to match the
prior sequence.

61d791365b drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.

This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.

So just initialize 'val' to zero to avoid the issue.

 Test results:
 
 The first ones are container based builds of tools/perf with and without libelf
 support.  Where clang is available, it is also used to build perf with/without
 libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
 when clang and its devel libraries are installed.
 
 The objtool and samples/bpf/ builds are disabled now that I'm switching from
 using the sources in a local volume to fetching them from a http server to
 build it inside the container, to make it easier to build in a container cluster.
 Those will come back later.
 
 Several are cross builds, the ones with -x-ARCH and the android one, and those
 may not have all the features built, due to lack of multi-arch devel packages,
 available and being used so far on just a few, like
 debian:experimental-x-{arm64,mipsel}.
 
 The 'perf test' one will perform a variety of tests exercising
 tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
 with a variety of command line event specifications to then intercept the
 sys_perf_event syscall to check that the perf_event_attr fields are set up as
 expected, among a variety of other unit tests.
 
 Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
 with a variety of feature sets, exercising the build with an incomplete set of
 features as well as with a complete one. It is planned to have it run on each
 of the containers mentioned above, using some container orchestration
 infrastructure. Get in contact if interested in helping having this in place.

11cc92eb74 genirq: Fix export of irq_to_desc() for powerpc KVM
Commit 64a1b95bb9 ("genirq: Restrict export of irq_to_desc()") removed
the export of irq_to_desc() unless powerpc KVM is being built, because
there is still a use of irq_to_desc() in modular code there.

However it used:

  #ifdef CONFIG_KVM_BOOK3S_64_HV

Which doesn't work when that symbol is =m, leading to a build failure:

  ERROR: modpost: "irq_to_desc" [arch/powerpc/kvm/kvm-hv.ko] undefined!

Fix it by checking for the definedness of the correct symbol which is
CONFIG_KVM_BOOK3S_64_HV_MODULE.

Fixes: 64a1b95bb9 ("genirq: Restrict export of irq_to_desc()")
