[ Upstream commit 8d7c52cb4184d3dc26dde62b4f5acd48de0768ae ]
The only iommu function call in this driver is a
tegra_dev_iommu_get_stream_id() which does not allocate anything and does
not take any reference.
So there is no point in calling iommu_fwspec_free() in the remove function.
Remove this incorrect function call.

Currently we only support Vector for SMP platforms, that is, all SMP
cores have the same vlenb. If we happen to detect a mismatching vlen, it
is better to just fail bootting it up to prevent further race/scheduling
issues.
Also, move .Lsecondary_park forward and chage `tail smp_callin` into a
regular call in the early assembly. So a core would be parked right
after a return from smp_callin. Note that a successful smp_callin
does not return.

[ Upstream commit c93637e6a4c4e1d0e85ef7efac78d066bbb24d96 ]
Avoid large backtrace, it is sufficient to warn the user that there has
been a link problem. Either the link has failed and the system is in need
of maintenance, or the link continues to work and user has been informed.
The message from the warning can be looked up in the sources.
This makes an actual link issue less verbose.
First of all, this controller has a limitation in that the controller
driver has to assist the hardware with transition to L1 link state by
writing L1IATN to PMCTRL register, the L1 and L0 link state switching
is not fully automatic on this controller.
In case of an ASMedia ASM1062 PCIe SATA controller which does not support
ASPM, on entry to suspend or during platform pm_test, the SATA controller
enters D3hot state and the link enters L1 state. If the SATA controller
wakes up before rcar_pcie_wakeup() was called and returns to D0, the link
returns to L0 before the controller driver even started its transition to
L1 link state. At this point, the SATA controller did send an PM_ENTER_L1
DLLP to the PCIe controller and the PCIe controller received it, and the
PCIe controller did set PMSR PMEL1RX bit.
Once rcar_pcie_wakeup() is called, if the link is already back in L0 state
and PMEL1RX bit is set, the controller driver has no way to determine if
it should perform the link transition to L1 state, or treat the link as if
it is in L0 state. Currently the driver attempts to perform the transition
to L1 link state unconditionally, which in this specific case fails with a
PMSR L1FAEG poll timeout, however the link still works as it is already
back in L0 state.
Reduce this warning verbosity. In case the link is really broken, the
rcar_pcie_config_access() would fail, otherwise it will succeed and any
system with this controller and ASM1062 can suspend without generating
a backtrace.

[ Upstream commit 903534fa7d30214d8ba840ab1cd9e917e0c88e41 ]
pbus_size_mem() keeps the size of the optional resources in
children_add_size. When calculating the PCI bridge window size,
calculate_memsize() lower bounds size by old_size before adding
children_add_size and performing the window size alignment. This
results in double counting for the resources in children_add_size
because old_size may be based on the previous size of the bridge
window after it has already included children_add_size (that is,
size1 in pbus_size_mem() from an earlier invocation of that
function).
As a result, on repeated remove of the bus & rescan cycles the resource
size keeps increasing when children_add_size is non-zero as can be seen
from this extract:
iomem0: 23fffd00000-23fffdfffff : PCI Bus 0000:03 # 1MiB
iomem1: 20000000000-200001fffff : PCI Bus 0000:03 # 2MiB
iomem2: 20000000000-200002fffff : PCI Bus 0000:03 # 3MiB
iomem3: 20000000000-200003fffff : PCI Bus 0000:03 # 4MiB
iomem4: 20000000000-200004fffff : PCI Bus 0000:03 # 5MiB
Solve the double counting by moving old_size check later in
calculate_memsize() so that children_add_size is already accounted for.
After the patch, the bridge window retains its size as expected:
iomem0: 23fffd00000-23fffdfffff : PCI Bus 0000:03 # 1MiB
iomem1: 20000000000-200000fffff : PCI Bus 0000:03 # 1MiB

Instead of getting the epc_features from pci_epc_get_features() API, use
the cached pci_epf_test::epc_features value to avoid the NULL check. Since
the NULL check is already performed in pci_epf_test_bind(), having one more
check in pci_epf_test_core_init() is redundant and it is not possible to
hit the NULL pointer dereference.
Also with commit a01e7214bef9 ("PCI: endpoint: Remove "core_init_notifier"

the following false positive Smatch warning:
drivers/pci/endpoint/functions/pci-epf-test.c:784 pci_epf_test_core_init() error: we previously assumed 'epc_features' could be null (see line 747)

The sorting in iio_gts_build_avail_time_table is not working as intended.
It could result in an out-of-bounds access when the time is zero.
Here are more details:
1. When the gts->itime_table[i].time_us is zero, e.g., the time
sequence is `3, 0, 1`, the inner for-loop will not terminate and do
out-of-bound writes. This is because once `times[j] > new`, the value
`new` will be added in the current position and the `times[j]` will be
moved to `j+1` position, which makes the if-condition always hold.
Meanwhile, idx will be added one, making the loop keep running without
termination and out-of-bound write.
2. If none of the gts->itime_table[i].time_us is zero, the elements
will just be copied without being sorted as described in the comment
"Sort times from all tables to one and remove duplicates".

removed the implicit pin operation from qxl's vmap code. This is the
correct behavior for GEM and PRIME interfaces, but the pin is still
needed for qxl internal operation.
Also add a corresponding function qxl_bo_vunmap_and_unpin() and remove
the old qxl_bo_vmap() helpers.
Future directions: BOs should not be pinned or vmapped unnecessarily.
The pin-and-vmap operation should be removed from the driver and a
temporary mapping should be established with a vmap_local-like helper.

Prior to the commit identified below, call_transmit_status() would
handle -EPERM and other errors related to an unreachable server by
falling through to call_status() which added a 3-second delay and
handled the failure as a timeout.
Since that commit, call_transmit_status() falls through to
handle_bind(). For UDP this moves straight on to handle_connect() and
handle_transmit() so we immediately retransmit - and likely get the same
error.
This results in an indefinite loop in __rpc_execute() which triggers a
soft-lockup warning.
For the errors that indicate an unreachable server,
call_transmit_status() should fall back to call_status() as it did
before. This cannot cause the thundering herd that the previous patch
was avoiding, as the call_status() will insert a delay.

Avoid FastReg operations getting MW_BIND_ERR after a reconnect.
rpcrdma_reqs_reset() is called on transport tear-down to get each
rpcrdma_req back into a clean state.
MRs on req->rl_registered are waiting for a FastReg, are already
registered, or are waiting for invalidation. If the transport is
being torn down when reqs_reset() is called, the matching LocalInv
might never be posted. That leaves these MR registered /and/ on
req->rl_free_mrs, where they can be re-used for the next
connection.
Since xprtrdma does not keep specific track of the MR state, it's
not possible to know what state these MRs are in, so the only safe
thing to do is release them immediately.

Commit 16c2004d9e4d ("mfd: omap-usb-tll: Allocate driver data at once")
changed the memory allocation of 'tll' to consolidate it into a single
allocation, introducing an incorrect size calculation.
In particular, the allocation for the array of pointers was converted
into a single-pointer allocation.
The memory allocation used to occur in two steps:
tll = devm_kzalloc(dev, sizeof(struct usbtll_omap), GFP_KERNEL);
tll->ch_clk = devm_kzalloc(dev, sizeof(struct clk *) * tll->nch,
GFP_KERNEL);
And it turned that into the following allocation:
tll = devm_kzalloc(dev, sizeof(*tll) + sizeof(tll->ch_clk[nch]),
GFP_KERNEL);
sizeof(tll->ch_clk[nch]) returns the size of a single pointer instead of
the expected nch pointers.
This bug went unnoticed because the allocation size was small enough to
fit within the minimum size of a memory allocation for this particular
case [1].
The complete allocation can still be done at once with the struct_size
macro, which comes in handy for structures with a trailing flexible
array.
Fix the memory allocation to obtain the original size again.

this case the devfreq infrastructure isn't notified that the GPU is

no time will be accounted for the GPU being busy.

This reverts commit da1afe8e6099980fe1e2fd7436dca284af9d3f29.
Commit 699a8c7c4bd3 ("leds: Add of_led_get() and led_put()"), introduced in
5.5, added of_led_get() and led_put() but missed a put_device() in
led_put(), thus creating a leak in case the consumer device is removed.
Arguably device removal was not very popular, so this went apparently
unnoticed until 2022. In January 2023 two different patches got merged to
fix the same bug:
- commit da1afe8e6099 ("leds: led-core: Fix refcount leak in of_led_get()")
- commit 445110941eb9 ("leds: led-class: Add missing put_device() to led_put()")
They fix the bug in two different ways, which creates no patch conflicts,
and both were merged in v6.2. The result is that now there is one more
put_device() than get_device()s, instead of one less.
Arguably device removal is not very popular yet, so this apparently hasn't
been noticed as well up to now. But it blew up here while I'm working with
device tree overlay insertion and removal. The symptom is an apparently
unrelated list of oopses on device removal, with reasons:
kernfs: can not remove 'uevent', no directory
kernfs: can not remove 'brightness', no directory
kernfs: can not remove 'max_brightness', no directory
...
Here sysfs fails removing attribute files, which is because the device name
changed and so the sysfs path. This is because the device name string got
corrupted, which is because it got freed too early and its memory reused.
Different symptoms could appear in different use cases.
Fix by removing one of the two fixes.
The choice was to remove commit da1afe8e6099 because:
* it is calling put_device() inside of_led_get() just after getting the
device, thus it is basically not refcounting the LED device at all
during its entire lifetime
* it does not add a corresponding put_device() in led_get(), so it fixes
only the OF case
The other fix (445110941eb9) is adding the put_device() in led_put() so it
covers the entire lifetime, and it works even in the non-DT case.

patterns with "/tmp/perf-", this fails.
Further debugging, commit 80d496be89ed ("perf report: Add support
for profiling JIT generated code") added support for profiling JIT
generated code. This patch handles dso's of form
"/tmp/perf-$PID.map" .
The check used "if (strncmp(self->name, "/tmp/perf-", 10) == 0)"
to match "/tmp/perf-$PID.map". With this commit, any dso in
/tmp/perf- folder will be considered separately for processing
(not only JIT created map files ). Fix this by changing the
string pattern to check for "/tmp/perf-%d.map". Add a helper
function is_perf_pid_map_name to do this check. In "struct dso",
dso->long_name holds the long name of the dso file. Since the
/tmp/perf-$PID.map check uses the complete name, use dso___long_name for
the string name.
With the fix,

[ Upstream commit ff16aeb9b83441b8458d4235496cf320189a0c60 ]
The 2 second sleep can cause the test to fail on very slow network file
systems because Perf ends up being killed before it finishes starting
up.
Fix it by making the leafloop workload end after a fixed time like the
other workloads so there is no need to kill it after 2 seconds.
Also remove the 1 second start sampling delay because it is similarly
fragile. Instead, search through all samples for a matching one, rather
than just checking the first sample and hoping it's in the right place.

[ Upstream commit 13bbe1c83bc401c2538c758228d27b4042b08341 ]
The Kconfig for platforms/arm64 has 'depends on ARM64 || COMPILE_TEST'.
However due to Makefile having just obj-$(CONFIG_ARM64) the subdir will
not be descended for !ARM64 platforms and thus the drivers won't get
built. This breaks modular builds of other driver drivers which depend
on arm64 platform drivers.

The whole framebuffer is cleared, so it's useless to rewrite the
background colored pixels. It allows to simplify the drawing
functions, and prepare the work for the set_pixel() callback.
v2:
* keep fg16/fg24/fg32 as variable name for the blit function.
* add drm_panic_is_pixel_fg() to avoid code duplication.

BOs in a bulk move have to share the same reservation object. That is
not the case in the ttm_bo_unreserve_bulk subtest. Update
ttm_bo_kunit_init() helper to accept dma_resv object so we can define
buffer objects that share the same resv. Update calls to that helper
accordingly.
