8465df4025 net/mlx5: Fix crdump chunks print
Crdump repeats itself every chunk of 256bytes.
That is due to bug of missing progressing offset while copying the data
from buffer to devlink_fmsg.

a39f165db5 i40e: allow reset in recovery mode
Driver waits after issuing a reset. When a reset takes too long a driver
gives up. Implemented by invoking PF reset in a loop. After defined
number of unsuccessful PF reset trials it returns error.
Without this patch PF reset fails when NIC is in recovery mode.

So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type()
to be public. It is required for recovery mode handling. Without this patch
recovery mode could not be detected in i40e_probe().

9889707b06 i40e: Fix crash caused by stress setting of VF MAC addresses
Add update to the VSI pointer passed to the i40e_set_vf_mac function.
If VF is in reset state the driver waits in i40e_set_vf_mac function
for the reset to be complete, yet after reset the vsi pointer
that was passed into this function is no longer valid.

The patch updates local VSI pointer directly from pf->vsi array,
by using the id stored in VF pointer (lan_vsi_idx).

Without this commit the driver might occasionally invoke general
protection fault in kernel and disable the OS entirely.

d4256c8e9a i40e: check_recovery_mode had wrong if statement
Function check_recovery_mode had wrong if statement.
Now we check proper FWS1B register values, which are responsible for
the recovery mode. Recovery mode has 4 values for x710 and 2 for x722.
That's why we need 6 different flags which are defined in the code.
Now in the if statement, we recognize type of mac address
and register value.
Without those changes driver could show wrong state.

bc6c1eaaed i40e: Check if transceiver implements DDM before access
Similar to the ixgbe issue fixed in:
655c914145 ("ixgbe: Check DDM existence in transceiver before access)

i40e has the same issue when reading eeprom from SFP's module that comply
with SFF-8472 but not implement the Digital Diagnostic Monitoring (DDM)
interface described in it. The existence of such area is specified by bit
6 of byte 92, set to 1 if implemented.

Without this patch, due to not checking this bit i40e fails to read SFP
module's eeprom with the follow message:

ethtool -m enP51p1s0f0
Cannot get Module EEPROM data: Input/output error

Because it fails to read the additional 256 bytes in which it was assumed
to exist the DDM data.

33b165684a i40e: reduce stack usage in i40e_set_fc
The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both
have giant structure on the stack, which makes each one use stack frames
larger than 500 bytes.

As clang decides one function into the other, we get a warning for
exceeding the frame size limit on 32-bit architectures:

drivers/net/ethernet/intel/i40e/i40e_common.c:1654:23: error: stack frame size of 1116 bytes in function 'i40e_set_fc' [-Werror,-Wframe-larger-than=]

When building with gcc, the inlining does not happen, but i40e_set_fc()
calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the
kernel stack just as much.

The parts that actually use large stacks don't overlap, so make sure
each one is a separate function, and mark them as noinline_for_stack to
prevent the compilers from combining them again.

d9c5c08341 libperf: Fix alignment trap with xyarray contents in 'perf stat'
Following the patch 'perf stat: Fix --no-scale', an alignment trap
happens in process_counter_values() on ARMv7 platforms due to the
attempt to copy non 64 bits aligned double words (pointed by 'count')
via a NEON vectored instruction ('vld1' with 64 bits alignment
constraint).

This patch sets a 64 bits alignment constraint on 'contents[]' field in
'struct xyarray' since the 'count' pointer used above points to such a
structure.

allocate two blocks: left and right.  If right block's allocation
failed, the left block will be unlocked and marked dirty.  If this
happened, the left block'ss content is zero, because it wasn't
initialized with the btree struct before the attempot to allocate the
right block.  Upon return, when flushing the left block to disk, the
validator will fail when check this block.  Then a BUG_ON is raised.

Fix this by completely initializing the left block before allocating and
initializing the right block.

7010998c6c nl80211: add NL80211_CMD_UPDATE_FT_IES to supported commands
Add NL80211_CMD_UPDATE_FT_IES to supported commands. In mac80211 drivers,
this can be implemented via existing NL80211_CMD_AUTHENTICATE and
NL80211_ATTR_IE, but non-mac80211 drivers have a separate command for
this. A driver supports FT if it either is mac80211 or supports this
command.

b26af93044 mac80211: minstrel_ht: fix infinite loop because supported is not being shifted
Currently the for-loop will spin forever if variable supported is
non-zero because supported is never changed.  Fix this by adding in

Add the GET_BATT_PPID_INFO=0x8A command to the allowlist of accepted

verifying the contents of some of the arguments, I also restructure
the request to use a union of the argument structs. Also, zero out the

The big endian version uses driver compatible "fsl,ls1021a-qspi" and

   structure to take advantage of others' grace periods.

 - Also added a small commit that avoids needlessly inflicting
   scheduler-clock ticks on callback-offloaded CPUs.

 - Forward-progress improvements for no-CBs CPUs: Reduce contention
   on ->nocb_lock guarding ->cblist.

 - Forward-progress improvements for no-CBs CPUs: Add ->nocb_bypass
