The TOS value that is returned to user space in the route get reply is

fine when the matched route is configured with a TOS as it would not
match if its TOS value did not match the one with which the lookup was

However, matching on TOS is only performed when the route's TOS is not

This driver predates first git commit, and it turns out back then
of_platform_device_create worked differently than it does today.

In the xmon disassembly code there are several CPU feature checks to
determine what dialects should be passed to the disassembler. The
dialect controls which instructions the disassembler will recognise.
Unfortunately the checks are incorrect, because instead of passing a
single CPU feature they are passing a mask of feature bits.
For example the code:
if (cpu_has_feature(CPU_FTRS_POWER5))
dialect |= PPC_OPCODE_POWER5;
Is trying to check if the system is running on a Power5 CPU. But
CPU_FTRS_POWER5 is a mask of *all* the feature bits that are enabled on
a Power5.
In practice the test will always return true for any 64-bit CPU, because
at least one bit in the mask will be present in the CPU_FTRS_ALWAYS
mask.
Similarly for all the other checks against CPU_FTRS_xx masks.
Rather than trying to match the disassembly behaviour exactly to the
current CPU, just differentiate between 32-bit and 64-bit, and Altivec,
VSX and HTM.
That will cause some instructions to be shown in disassembly even
on a CPU that doesn't support them, but that's OK, objdump -d output
has the same behaviour, and if anything it's less confusing than some
instructions not being disassembled.

When PERST# assert and deassert happens on the PERST# supported platforms,
both iATU0 and iATU6 will map inbound window to BAR0. DMA will access the
area that was previously allocated (iATU0) for BAR0, instead of the new
area (iATU6) for BAR0.
Right now, this isn't an issue because both iATU0 and iATU6 should
translate inbound accesses to BAR0 to the same allocated memory area.
However, having two separate inbound mappings for the same BAR is a
disaster waiting to happen.
The mappings between PCI BAR and iATU inbound window are maintained in the
dw_pcie_ep::bar_to_atu[] array. While allocating a new inbound iATU map for
a BAR, dw_pcie_ep_inbound_atu() API checks for the availability of the
existing mapping in the array and if it is not found (i.e., value in the
array indexed by the BAR is found to be 0), it allocates a new map value
using find_first_zero_bit().
The issue is the existing logic failed to consider the fact that the map
value '0' is a valid value for BAR0, so find_first_zero_bit() will return
'0' as the map value for BAR0 (note that it returns the first zero bit
position).
Due to this, when PERST# assert + deassert happens on the PERST# supported
platforms, the inbound window allocation restarts from BAR0 and the
existing logic to find the BAR mapping will return '6' for BAR0 instead of
'0' due to the fact that it considers '0' as an invalid map value.
Fix this issue by always incrementing the map value before assigning to
bar_to_atu[] array and then decrementing it while fetching. This will make
sure that the map value '0' always represents the invalid mapping."

[ Upstream commit 01a0a6cc8cfd9952e72677d48d56cf6bc4e3a561 ]
There's two problems with shared RCGs.
The first problem is that they incorrectly report the parent after
commit 703db1f5da ("clk: qcom: rcg2: Cache CFG register updates for
parked RCGs"). That's because the cached CFG register value needs to be
populated when the clk is registered. clk_rcg2_shared_enable() writes
the cached CFG register value 'parked_cfg'. This value is initially zero
due to static initializers. If a driver calls clk_enable() before
setting a rate or parent, it will set the parent to '0' which is
(almost?) always XO, and may not reflect the parent at registration. In
the worst case, this switches the RCG from sourcing a fast PLL to the
slow crystal speed.
The second problem is that the force enable bit isn't cleared. The force
enable bit is only used during parking and unparking of shared RCGs.
Otherwise it shouldn't be set because it keeps the RCG enabled even when
all the branches on the output of the RCG are disabled (the hardware has
a feedback mechanism so that any child branches keep the RCG enabled
when the branch enable bit is set). This problem wastes power if the clk
is unused, and is harmful in the case that the clk framework disables
the parent of the force enabled RCG. In the latter case, the GDSC the
shared RCG is associated with will get wedged if the RCG's source clk is
disabled and the GDSC tries to enable the RCG to do "housekeeping" while
powering on.
Both of these problems combined with incorrect runtime PM usage in the
display driver lead to a black screen on Qualcomm sc7180 Trogdor
chromebooks. What happens is that the bootloader leaves the
'disp_cc_mdss_rot_clk' enabled and the 'disp_cc_mdss_rot_clk_src' force
enabled and parented to 'disp_cc_pll0'. The mdss driver probes and
runtime suspends, disabling the mdss_gdsc which uses the
'disp_cc_mdss_rot_clk_src' for "housekeeping". The
'disp_cc_mdss_rot_clk' is disabled during late init because the clk is
unused, but the parent 'disp_cc_mdss_rot_clk_src' is still force enabled
because the force enable bit was never cleared. Then 'disp_cc_pll0' is
disabled because it is also unused. That's because the clk framework
believes the parent of the RCG is XO when it isn't. A child device of
the mdss device (e.g. DSI) runtime resumes mdss which powers on the
mdss_gdsc. This wedges the GDSC because 'disp_cc_mdss_rot_clk_src' is
parented to 'disp_cc_pll0' and that PLL is off. With the GDSC wedged,
mdss_runtime_resume() tries to enable 'disp_cc_mdss_mdp_clk' but it
can't because the GDSC has wedged all the clks associated with the GDSC
causing clks to stay stuck off.
This leads to the following warning seen at boot and a black screen
because the display driver fails to probe.

Fix these problems by parking shared RCGs at boot. This will properly
initialize the parked_cfg struct member so that the parent is reported
properly and ensure that the clk won't get stuck on or off because the
RCG is parented to the safe source (XO).

There are two issues around seqpacket_allow:
1. seqpacket_allow is not initialized when socket is
created. Thus if features are never set, it will be
read uninitialized.
2. if VIRTIO_VSOCK_F_SEQPACKET is set and then cleared,
then seqpacket_allow will not be cleared appropriately
(existing apps I know about don't usually do this but
it's legal and there's no way to be sure no one relies
on this).
To fix:
- initialize seqpacket_allow after allocation
- set it unconditionally in set_features

Smatch complains about inconsistent NULL checking in vpci_scan_bus():
drivers/pci/endpoint/functions/pci-epf-vntb.c:1024 vpci_scan_bus() error: we previously assumed 'vpci_bus' could be null (see line 1021)
Instead of printing an error message and then crashing we should return
an error code and clean up.
Also the NULL check is reversed so it prints an error for success
instead of failure.

acpi_get_first_physical_node() can return NULL in several cases (no such
device, ACPI table error, reference count drop to 0, etc).
Existing check just emit error message, but doesn't perform return.
Then this NULL pointer is passed to devm_acpi_dev_add_driver_gpios()
where it is dereferenced.
Adjust this error handling by adding error code return.

cur_cpu_spec->cpu_name is appended to ppc_hw_desc before cur_cpu_spec
has taken on its final value. This is illustrated on pseries by
comparing the CPU name as reported at boot ("POWER8E (raw)") to the
contents of /proc/cpuinfo ("POWER8 (architected)"):
$ dmesg | grep Hardware
Hardware name: IBM,8408-E8E POWER8E (raw) 0x4b0201 0xf000004 \
of:IBM,FW860.50 (SV860_146) hv:phyp pSeries
$ grep -m 1 ^cpu /proc/cpuinfo
cpu : POWER8 (architected), altivec supported
Some 44x models would appear to be affected as well; see
identical_pvr_fixup().
This results in incorrect CPU information in stack dumps --
ppc_hw_desc is an input to dump_stack_set_arch_desc().
Delay gathering the CPU name until after all potential calls to
identify_cpu().

[ Upstream commit 0c5275bf75ec3708d95654195ae4ed80d946d088 ]
When creating a QP, one of the attributes is TS format (timestamp).
In some devices, we have a limitation that all QPs should have the same
ts_format. The ts_format is chosen based on the device's capability.
The qp_ts_format cap resides under the RoCE caps table, and the
cap will be 0 when RoCE is disabled. So when RoCE is disabled, the
value that should be queried is sq_ts_format under HCA caps.
Consider the case when the system supports REAL_TIME_TS format (0x2),
some QPs are created with REAL_TIME_TS as ts_format, and afterwards
RoCE gets disabled. When trying to construct a new QP, we can't use
the qp_ts_format, that is queried from the RoCE caps table, Since it
leads to passing 0x0 (FREE_RUNNING_TS) as the value of the qp_ts_format,
which is different than the ts_format of the previously allocated
QPs REAL_TIME_TS format (0x2).
Thus, to resolve this, read the sq_ts_format, which also reflect
the supported ts format for the QP when RoCE is disabled.
