[ Upstream commit 5818c683a619c534c113e1f66d24f636defc29bc ]

If an ARM mapping symbol shares an address with a valid symbol,
find_elf_symbol can currently return the mapping symbol instead, as the
symbol is not validated. This can result in confusing warnings:

  WARNING: vmlinux.o(.text+0x18f4028): Section mismatch in reference
  from the function set_reset_devices() to the variable .init.text:$x.0

This change adds a call to is_valid_name to find_elf_symbol, similarly
to how it's already used in find_elf_symbol2.

[why]
phy_pix_clk is one of the variable used to check if one PLL can be shared
with displays having common mode set configuration. As of now
phy_pix_clock varialbe is calculated in function dc_validate_stream().
dc_validate_stream() function is called after clocks are assigned for the
new display. Due to this during hotplug, when PLL sharing conditions are
checked for new display phy_pix_clk variable will be 0 and for displays
that are already enabled phy_pix_clk will have some value. Hence PLL will
not be shared and if the display hardware doesn't have any more PLL to
assign, mode set will fail due to resource unavailability.

[how]
Instead of only calculating the phy_pix_clk variable after the PLL is
assigned for new display, this patch calculates phy_pix_clk also during
the before assigning the PLL for new display.

Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block)
allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is
used by them, can read only up to 255 bytes at once. Normally, it's
not a big issue as DPCD or EDID reads won't (hopefully) exceed that
value.
The real issue here is the revocation list read during the HDCP
authentication process. (problematic use case:
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152)
The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv +
4 bytes of an additional info).
In other words - CTSes with HDCP Repeater won't pass without this
fix. Oh, and the driver will most likely stop working (best case
scenario).

If a TX hang occurs, we attempt to recover by incrementally resetting.
If we're starved for CPU time, it's possible the reset doesn't actually
complete (or even fire) before another tx_timeout fires causing us to
fly through the different resets without actually doing them.

This adds a bit to set and check if a timeout recovery is already
pending and, if so, bail out of tx_timeout.  The bit will get cleared at
the end of i40e_rebuild when reset is complete.

EC_MKBP_EVENT_SENSOR_FIFO events can be triggered for a variety of
reasons, and there are very few cases in which they should be treated as
wakeup interrupts (particularly, when a certain
MOTIONSENSE_MODULE_FLAG_* is set, but this is not even supported in the
mainline cros_ec_sensor driver yet). Most of the time, they are benign
sensor readings. In any case, the top-level cros_ec device doesn't know
enough to determine that they should wake the system, and so it should
not report the event. This would be the job of the cros_ec_sensors
driver to parse.

This patch adds checks to cros_ec_get_next_event() such that it doesn't
signal 'wakeup' for events of type EC_MKBP_EVENT_SENSOR_FIFO.

This patch is particularly relevant on devices like Scarlet (Rockchip
RK3399 tablet, known as Acer Chromebook Tab 10), where the EC firmware
reports sensor events much more frequently. This was causing
/sys/power/wakeup_count to increase very frequently, often needlessly
interrupting our ability to suspend the system.

The Intel EG20T Platform Controller Hub used on the MIPS Boston
development board supports prefetching memory to optimize DMA transfers.
Unfortunately for unknown reasons this doesn't work well with some MIPS
CPUs such as the P6600, particularly when using an I/O Coherence Unit
(IOCU) to provide cache-coherent DMA. In these systems it is common for
DMA data to be lost, resulting in broken access to EG20T devices such as
the MMC or SATA controllers.

Support for a DT property to configure the prefetching was added a while
back by commit 549ce8f1 ("misc: pch_phub: Read prefetch value from
device tree if passed") but we never added the DT snippet to make use of
it. Add that now in order to disable the prefetching & fix DMA on the
affected systems.

In the "aes-fixed-time" AES implementation, disable interrupts while
accessing the S-box, in order to make cache-timing attacks more
difficult.  Previously it was possible for the CPU to be interrupted
while the S-box was loaded into L1 cache, potentially evicting the
cachelines and causing later table lookups to be time-variant.

In tests I did on x86 and ARM, this doesn't affect performance
significantly.  Responsiveness is potentially a concern, but interrupts
are only disabled for a single AES block.

Note that even after this change, the implementation still isn't
necessarily guaranteed to be constant-time; see
https://cr.yp.to/antiforgery/cachetiming-20050414.pdf for a discussion
of the many difficulties involved in writing truly constant-time AES
software.  But it's valuable to make such attacks more difficult.

After a LOGO in response to an ABTS timeout, a PLOGI wasn't issued to
re-establish the login.  An nlp_type check in the LOGO completion
handler failed to restart discovery for NVME targets.  Revised the
nlp_type check for NVME as well as SCSI.

While reviewing the LOGO handling a few other issues were seen and
were addressed:

- Better lock synchronization around ndlp data types

- When the ABTS times out, unregister the RPI before sending the LOGO
  so that all local exchange contexts are cleared and nothing received
  while awaiting LOGO/PLOGI handling will be accepted.

- LOGO handling optimized to:
   Wait only R_A_TOV for a response.
   It doesn't need to be retried on timeout. If there wasn't a
     response, a PLOGI will be sent, thus an implicit logout
     applies as well when the other port sees it.
   If there is a response, any kind of response is considered "good"
     and the XRI quarantined for a exchange qualifier window.

- PLOGI is issued as soon a LOGO state is resolved.

[ Upstream commit dc730212e8a378763cb182b889f90c8101331332 ]

Call sas_remove_host() before removing the target devices in the driver's
.remove() callback function(i.e. during driver unload time).  So that
driver can provide a way to allow SYNC CACHE, START STOP unit commands
etc. (which are issued from SML) to the target drives during driver unload
time.

Once sas_remove_host() is called before removing the target drives then
driver can just clean up the resources allocated for target devices and no
need to call sas_port_delete_phy(), sas_port_delete() API's as these API's
internally called from sas_remove_host().

Commit 2ea9f12c ("ath10k: add new cipher suite support") added a new
n_cipher_suites HW param with a fallback value and a warning log. Commit
03a72288 ("ath10k: wmi: add hw params entry for wcn3990") later
added WCN3990 HW entries, but it missed the n_cipher_suites.

Rather than seeing this warning every boot

  ath10k_snoc 18800000.wifi: invalid hw_params.n_cipher_suites 0

let's provide the appropriate value.

[ Upstream commit 819bec35c8c9706185498c9222bd244e0781ad35 ]

Prevent possible race by parallel threads between ipu_image_convert_run()
and ipu_image_convert_unprepare(). This involves setting ctx->aborting
to true unconditionally so that no new job runs can be queued during
unprepare, and holding the ctx->aborting flag until the context is freed.

Note that the "normal" ipu_image_convert_abort() case (e.g. not during
context unprepare) should clear the ctx->aborting flag after aborting
any active run and clearing the context's pending queue. This is because
it should be possible to continue to use the conversion context and queue
more runs after an abort.

[ Upstream commit b82592199032bf7c778f861b936287e37ebc9f62 ]

If the number of NUMA nodes exceeds the number of MSI/MSI-X interrupts
which are allocated for a device, the interrupt affinity spreading code
fails to spread them across all nodes.

The reason is, that the spreading code starts from node 0 and continues up
to the number of interrupts requested for allocation. This leaves the nodes
past the last interrupt unused.

This results in interrupt concentration on the first nodes which violates
the assumption of the block layer that all nodes are covered evenly. As a
consequence the NUMA nodes above the number of interrupts are all assigned
to hardware queue 0 and therefore NUMA node 0, which results in bad
performance and has CPU hotplug implications, because queue 0 gets shut
down when the last CPU of node 0 is offlined.

Go over all NUMA nodes and assign them round-robin to all requested
interrupts to solve this.

It turns out that TCON TOP registers in H6 SoC have non-zero reset
value. This may cause issues if bits are not changed during
configuration.

To prevent that, initialize registers to 0.
