Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.

Quite obviously the driver depends on I2C_MUX, but adding a "depends on"

Since capturing the error state requires fiddling around with the GGTT
to read arbitrary buffers and is itself run under stop_machine(), it
deadlocks the machine (effectively a hard hang) when run in conjunction
with Broxton's VTd workaround to serialize GGTT access.
v2: Store the ERR_PTR in first_error so that the error can be reported
to the user via sysfs.

This patch changes to use rtnl_lock only during a reset to avoid
deadlock that could occur when a thread operating close is holding
rtnl_lock and waiting for reset_lock acquired by another thread,
which is waiting for rtnl_lock in order to set the number of tx/rx
queues during a reset.
Also, we now setting the number of tx/rx queues during a soft reset

The getter callers doesn't know the valid Physical Queues (PQ) values.
This patch makes sure that a valid PQ will always be returned.
The patch consists of 3 fixes:
- When qed_init_qm_get_idx_from_flags() receives a disabled flag, it
returned PQ 0, which can potentially be another function's pq. Verify
that flag is enabled, otherwise return default start_pq.
- When qed_init_qm_get_idx_from_flags() receives an unknown flag, it
returned NULL and could lead to a segmentation fault. Return default
start_pq instead.
- A modulo operation was added to MCOS/VFS PQ getters to make sure the
PQ returned is in range of the required flag.

In ena_remove() we have the following stack call:
ena_remove()
unregister_netdev()
ena_destroy_device()
netif_carrier_off()
Calling netif_carrier_off() causes linkwatch to try to handle the
link change event on the already unregistered netdev, which leads
to a read from an unreadable memory address.
This patch switches the order of the two functions, so that
netif_carrier_off() is called on a regiestered netdev.
To accomplish this fix we also had to:
1. Remove the set bit ENA_FLAG_TRIGGER_RESET
2. Add a sanitiy check in ena_close()
both to prevent double device reset (when calling unregister_netdev()
ena_close is called, but the device was already deleted in
ena_destroy_device()).
3. Set the admin_queue running state to false to avoid using it after
device was reset (for example when calling ena_destroy_all_io_queues()
right after ena_com_dev_reset() in ena_down)

During resume from hibernation if ena_restore_device fails,
ena_com_dev_reset() is called, and uses the readless read mechanism,
which was already destroyed by the call to
ena_com_mmio_reg_read_request_destroy(). This causes a NULL pointer
reference.
In this commit we switch the call order of the above two functions
to avoid this crash.

Different from processing the addstrm_out request, The receiver handles
an addstrm_in request by sending back an addstrm_out request to the
sender who will increase its stream's in and incnt later.
Now stream->incnt has been increased since it sent out the addstrm_in
request in sctp_send_add_streams(), with the wrong stream->incnt will
even cause crash when copying stream info from the old stream's in to
the new one's in sctp_process_strreset_addstrm_out().
This patch is to fix it by simply removing the stream->incnt change
from sctp_send_add_streams().

In case of striding RQ, we use MPWRQ (Multi Packet WQE RQ), which means
that WQE (RX descriptor) can be used for many packets and so the WQE is
much bigger than MTU. In virtualization setups where the port mtu can
be larger than the vf mtu, if received packet is bigger than MTU, it
won't be dropped by HW on too small receive WQE. If we use linear SKB in
striding RQ, since each stride has room for mtu size payload and skb
info, an oversized packet can lead to crash for crossing allocated page
boundary upon the call to build_skb. So driver needs to check packet
size and drop it.
Introduce new SW rx counter, rx_oversize_pkts_sw_drop, which counts the
number of packets dropped by the driver for being too large.
As a new field is added to the RQ struct, re-open the channels whenever
this field is being used in datapath (i.e., in the case of linear
Striding RQ).

The mlx5e channels should be closed before mlx5i_uninit_underlay_qp
puts the QP into RST (reset) state during mlx5i_close. Currently QP
state incorrectly set to RST before channels got deactivated and closed,
since mlx5_post_send request expects QP in RTS (Ready To Send) state.
The fix is to keep QP in RTS state until mlx5e channels get closed
and to reset QP afterwards.
Also this fix is simply correct in order to keep the open/close flow
symmetric, i.e mlx5i_init_underlay_qp() is called first thing at open,
the correct thing to do is to call mlx5i_uninit_underlay_qp() last thing
at close, which is exactly what this patch is doing.

not the same key value used when remove SA context operation is

So just delete the bad job from mirror list directly
Changes in v3:
- Add a helper function to delete the bad jobs from mirror list and call
it directly *before* the job's fence is signaled
Changes in v2:
- delete the useless list node check
- also delete bad jobs in drm_sched_main because:
kthread_unpark(ring->sched.thread) will be invoked very early before
amdgpu_device_gpu_recover's return, then drm_sched_main will have
chance to pick up a new job from the job queue. This new job will be
added into the mirror list and processed by amdgpu_job_run, but may
not be deleted from the mirror list on time due to the same reason.
And finally re-processed by drm_sched_job_recovery

Page writeback indirectly handles shared extents via the existence
of overlapping COW fork blocks. If COW fork blocks exist, writeback
always performs the associated copy-on-write regardless if the
underlying blocks are actually shared. If the blocks are shared,
then overlapping COW fork blocks must always exist.
fstests shared/010 reproduces a case where a buffered write occurs
over a shared block without performing the requisite COW fork
reservation. This ultimately causes writeback to the shared extent
and data corruption that is detected across md5 checks of the
filesystem across a mount cycle.
The problem occurs when a buffered write lands over a shared extent
that crosses an extent size hint boundary and that also happens to
have a partial COW reservation that doesn't cover the start and end
blocks of the data fork extent.
For example, a buffered write occurs across the file offset (in FSB
units) range of [29, 57]. A shared extent exists at blocks [29, 35]
and COW reservation already exists at blocks [32, 34]. After
accommodating a COW extent size hint of 32 blocks and the existing
reservation at offset 32, xfs_reflink_reserve_cow() allocates 32
blocks of reservation at offset 0 and returns with COW reservation
across the range of [0, 34]. The associated data fork extent is
still [29, 35], however, which isn't fully covered by the COW
reservation.
This leads to a buffered write at file offset 35 over a shared
extent without associated COW reservation. Writeback eventually
kicks in, performs an overwrite of the underlying shared block and
causes the associated data corruption.
Update xfs_reflink_reserve_cow() to accommodate the fact that a
delalloc allocation request may not fully cover the extent in the
data fork. Trim the data fork extent appropriately, just as is done
for shared extent boundaries and/or existing COW reservations that
happen to overlap the start of the data fork extent. This prevents
shared/010 failures due to data corruption on reflink enabled
filesystems.

Reading the sysfs files pp_sclk_od and pp_mclk_od return the
percentage difference between the VBIOS-provided default
frequency and the current (possibly user-set) frequency in
the highest SCLK and MCLK DPM states, respectively.
Writing to these files provides an easy mechanism for
setting a higher-than-default maximum frequency. We
normally only allow values >= 0 to be written here.
However, with the addition of pp_od_clk_voltage, we now
allow users to set custom DPM tables. If they then set
the maximum DPM state to something less than the default,
later reads of pp_*_od should return a negative value.
The highest DPM state is now less than the VBIOS-provided
default, so the percentage is negative.
The math to calculate this was originally performed with
unsigned values, meaning reads that should return negative
values returned meaningless data. This patch corrects that
issue and normalizes how all of the calculations are done
across the various hwmgr types.

The dst's mtu in transport can be updated by a non sctp place like
in xfrm where the MTU information didn't get synced between asoc,
transport and dst, so it is still needed to do the pmtu check
in sctp_packet_config.

As rfc7496#section4.5 says about SCTP_PR_SUPPORTED:
This socket option allows the enabling or disabling of the
negotiation of PR-SCTP support for future associations. For existing
associations, it allows one to query whether or not PR-SCTP support
was negotiated on a particular association.
It means only sctp sock's prsctp_enable can be set.
Note that for the limitation of SCTP_{CURRENT|ALL}_ASSOC, we will
add it when introducing SCTP_{FUTURE|CURRENT|ALL}_ASSOC for linux
sctp in another patchset.
v1->v2:
- drop the params.assoc_id check as Neil suggested.

Now sctp increases sk_wmem_alloc by 1 when doing set_owner_w for the
skb allocked in sctp_packet_transmit and decreases by 1 when freeing
this skb.
But when this skb goes through networking stack, some subcomponents
might change skb->truesize and add the same amount on sk_wmem_alloc.
However sctp doesn't know the amount to decrease by, it would cause
a leak on sk->sk_wmem_alloc and the sock can never be freed.
Xiumei found this issue when it hit esp_output_head() by using sctp
over ipsec, where skb->truesize is added and so is sk->sk_wmem_alloc.
Since sctp has used sk_wmem_queued to count for writable space since
Commit cd305c74b0f8 ("sctp: use sk_wmem_queued to check for writable
space"), it's ok to fix it by counting sk_wmem_alloc by skb truesize
in sctp_packet_transmit.
