49aba0bbab habanalabs: print warning when reset is requested
When the system administrator asks the driver to soft or hard reset the
device through sysfs, the driver should display a warning in the kernel log
to explain why it suddenly resets the device.

1fa185c656 habanalabs: re-factor H/W queues initialization
We want to remove the following restrictions/assumptions in our driver:
1. The H/W queue index is also the completion queue index.
2. The H/W queue index is also the IRQ number of the completion queue.
3. All queues of the same type have consecutive indexes.

Therefore we add the support for H/W queues of the same type with
nonconsecutive indexes and completion queue index and IRQ number different
than the H/W queue index.

76cedc739d habanalabs: remove stop-on-error flag from DMA
Stop-on-error mode in DMA is useful as it stops the transaction
immediately upon error e.g. page fault.
But it may cause the next command submission to fail as is leaves the DMA
in unstable state.
Therefore we remove the stop-on-error configuration from the DMA.
Stop-on-err is still available for debug.

3ec499c967 habanalabs: don't wait for ASIC CPU after reset
Upon reset of the ASIC, the driver would have waited for the CPU to come
out of reset before finishing the reset process. This was done for the
purpose of making the CPU available to answer FLR requests. However, when a
VM shuts down, the driver isn't removed so a reset never happens.
Therefore, remove this waiting period as we don't need it.

This series permits suspend/resume to work for the IPA driver
on the Qualcomm SC7180 SoC.  The IPA version on this SoC requires
interrupts to be enabled when the suspend and resume callbacks are
made, and the first patch moves away from using the noirq variants.
The second patch fixes a problem with resume that occurs because
pending interrupts were being cleared before starting a channel.

195ef57f87 net: ipa: do not clear interrupt in gsi_channel_start()
In gsi_channel_start() there is harmless-looking comment "Clear the
channel's event ring interrupt in case it's pending".  The intent
was to avoid getting spurious interrupts when first bringing up a
channel.

However we now use channel stop/start to implement suspend and
resume, and an interrupt pending at the time we resume is actually
something we don't want to ignore.

The very first time we bring up the channel we do not expect an
interrupt to be pending, and even if it were, the effect would
simply be to schedule NAPI on that channel, which would find nothing
to do, which is not a problem.

Stop clearing any pending IEOB interrupt in gsi_channel_start().
That leaves one caller of the trivial function gsi_isr_ieob_clear().
Get rid of that function and just open-code it in gsi_isr_ieob()
instead.

This fixes a problem where suspend/resume IPA v4.2 would get stuck
when resuming after a suspend.

These changes allow us to get rid of the multiple arrays we currently

with more per-trap information in the future. It will also allow us to
more easily add per-ASIC traps in future submissions.

200b7cca0b mlxsw: spectrum_trap: Store all trap data in one array
Each trap registered with devlink is mapped to one or more Rx listeners.
These listeners allow the switch driver (e.g., mlxsw_spectrum) to
register a function that is called when a packet is received (trapped)
for a specific reason.

Currently, three arrays are used to describe the mapping between the
logical devlink traps and the Rx listeners.

Instead, get rid of these arrays and store all the information in one
array that is easier to validate and extend with more per-trap
information.

a0c1d0eafd mptcp: Use 32-bit DATA_ACK when possible
RFC8684 allows to send 32-bit DATA_ACKs as long as the peer is not
sending 64-bit data-sequence numbers. The 64-bit DSN is only there for
extreme scenarios when a very high throughput subflow is combined with a
long-RTT subflow such that the high-throughput subflow wraps around the
32-bit sequence number space within an RTT of the high-RTT subflow.

It is thus a rare scenario and we should try to use the 32-bit DATA_ACK
instead as long as possible. It allows to reduce the TCP-option overhead
by 4 bytes, thus makes space for an additional SACK-block. It also makes
tcpdumps much easier to read when the DSN and DATA_ACK are both either
32 or 64-bit.

5e5502e012 net: dsa: mt7530: fix roaming from DSA user ports
When a client moves from a DSA user port to a software port in a bridge,
it cannot reach any other clients that connected to the DSA user ports.
That is because SA learning on the CPU port is disabled, so the switch
ignores the client's frames from the CPU port and still thinks it is at
the user port.

Fix it by enabling SA learning on the CPU port.

To prevent the switch from learning from flooding frames from the CPU
port, set skb->offload_fwd_mark to 1 for unicast and broadcast frames,
and let the switch flood them instead of trapping to the CPU port.
Multicast frames still need to be trapped to the CPU port for snooping,
so set the SA_DIS bit of the MTK tag to 1 when transmitting those frames
to disable SA learning.

befc42e5dd powerpc fixes for 5.7 #4
A fix for unrecoverable SLB faults in the interrupt exit path, introduced by the
 recent rewrite of interrupt exit in C.
 
 Four fixes for our KUAP (Kernel Userspace Access Prevention) support on 64-bit.
 These are all fairly minor with the exception of the change to evaluate the
 get/put_user() arguments before we enable user access, which reduces the amount
 of code we run with user access enabled.
 
 A fix for our secure boot IMA rules, if enforcement of module signatures is
 enabled at runtime rather than build time.
 
 A fix to our 32-bit VDSO clock_getres() which wasn't falling back to the syscall
 for unknown clocks.
 
 A build fix for CONFIG_PPC_KUAP_DEBUG on 32-bit BookS, and another for 40x.
 
 Thanks to:
   Christophe Leroy, Hugh Dickins, Nicholas Piggin, Aurelien Jarno, Mimi Zohar,
   Nayna Jain.

870c153cf0 blktrace: Report pid with note messages
Currently informational messages within block trace do not have PID
information of the process reporting the message included. With BFQ it
is sometimes useful to have the information and there's no good reason
to omit the information from the trace. So just fill in pid information
when generating note message.

96144d43fd iio: buffer: remove attrcount_orig var from sysfs creation
The variable no longer does anything.
It should have been removed with commit 2e036804d7 ("iio: buffer: remove
'scan_el_attrs' attribute group from buffer struct").
That was about the last time this was needed.
