5c4250092f wifi: mwl8k: Avoid -Wflex-array-member-not-at-end warnings
-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting
ready to enable it globally.

There is currently an object (`header`), at the beginning of multiple
structures, that contains a flexible structure (`struct mwl8k_cmd_pkt`),
for example:

struct mwl8k_cmd_get_hw_spec_sta {
        struct mwl8k_cmd_pkt header;

	...

	__le32 num_tx_desc_per_queue;
        __le32 total_rxd;
} __packed;

So, in order to avoid ending up with flexible-array members in the
middle of multiple other structs, we use the `__struct_group()` helper
to separate the flexible array from the rest of the members in the
flexible structure:

struct mwl8k_cmd_pkt {
        __struct_group(mwl8k_cmd_pkt_hdr, hdr, __packed,

	... the rest of the members

        );
        char payload[];
} __packed;

With the change described above, we now declare objects of the type of
the tagged struct, in this case `struct mwl8k_cmd_pkt_hdr`, without
embedding flexible arrays in the middle of another struct:

struct mwl8k_cmd_get_hw_spec_sta {
        struct mwl8k_cmd_pkt_hdr header;

        ...

        __le32 num_tx_desc_per_queue;
        __le32 total_rxd;
} __packed;

Also, update the type of a couple of variables and function parameters
from `struct mwl8k_cmd_pkt` to `struct mwl8k_cmd_pkt_hdr`.

So, with these changes, fix 33 of the following warnings[1]:
drivers/net/wireless/marvell/mwl8k.c:2353:30: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

of the VF state, in particular when a VF FLR was requested.  Add

57a1592784 iio: accel: mxc4005: Interrupt handling fixes
There are 2 issues with interrupt handling in the mxc4005 driver:

1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE
(0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt
it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables
all other interrupt sources in the INT_SRC1 register. On the MXC4005 this
is not an issue because only bit 0 of the register is used. On the MXC6655
OTOH this is a problem since bit7 is used as TC (Temperature Compensation)
disable bit and writing 1 to this disables Temperature Compensation which
should only be done when running self-tests on the chip.

Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable
the interrupts to fix this.

2. The datasheets for the MXC4005 / MXC6655 do not state what the reset
value for the INT_MASK0 and INT_MASK1 registers is and since these are
write only we also cannot learn this from the hw. Presumably the reset
value for both is all 0, which means all interrupts disabled.

Explicitly set both registers to 0 from mxc4005_chip_init() to ensure
both masks are actually set to 0.

18685451fc inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.

If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released.

This affects skb fragments reassembled via netfilter or similar
modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.

Eric Dumazet made an initial analysis of this bug.  Quoting Eric:
  Calling ip_defrag() in output path is also implying skb_orphan(),
  which is buggy because output path relies on sk not disappearing.

  A relevant old patch about the issue was :
  8282f27449 ("inet: frag: Always orphan skbs inside ip_defrag()")

  [..]

  net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
  inet socket, not an arbitrary one.

  If we orphan the packet in ipvlan, then downstream things like FQ
  packet scheduler will not work properly.

  We need to change ip_defrag() to only use skb_orphan() when really
  needed, ie whenever frag_list is going to be used.

Eric suggested to stash sk in fragment queue and made an initial patch.
However there is a problem with this:

If skb is refragmented again right after, ip_do_fragment() will copy
head->sk to the new fragments, and sets up destructor to sock_wfree.
IOW, we have no choice but to fix up sk_wmem accouting to reflect the
fully reassembled skb, else wmem will underflow.

This change moves the orphan down into the core, to last possible moment.
As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
offset into the FRAG_CB, else skb->sk gets clobbered.

This allows to delay the orphaning long enough to learn if the skb has
to be queued or if the skb is completing the reasm queue.

In the former case, things work as before, skb is orphaned.  This is
safe because skb gets queued/stolen and won't continue past reasm engine.

In the latter case, we will steal the skb->sk reference, reattach it to
the head skb, and fix up wmem accouting when inet_frag inflates truesize.

c628db0a68 sched/fair: Check root_domain::overload value before update
The root_domain::overload flag is 1 when there's any rq
in the root domain that has 2 or more running tasks. (Ie. it's overloaded.)

The root_domain structure itself is a global structure per cpuset island.

The ::overload flag is maintained the following way:

  - Set when adding a second task to the runqueue.

  - It is cleared in update_sd_lb_stats() during load balance,
    if none of the rqs have 2 or more running tasks.

This flag is used during newidle balance to see if its worth doing a full
load balance pass, which can be an expensive operation. If it is set,
then newidle balance will try to aggressively pull a task.

Since commit:

  630246a06a ("sched/fair: Clean-up update_sg_lb_stats parameters")

::overload is being written unconditionally, even if it has the same
value. The change in value of this depends on the workload, but on
typical workloads, it doesn't change all that often: a system is
either dominantly overloaded for substantial amounts of time, or not.

Extra writes to this semi-global structure cause unnecessary overhead, extra
bus traffic, etc. - so avoid it as much as possible.

Perf probe stats show that it's worth making this change (numbers are
with patch applied):

	1M    probe:sched_balance_newidle_L38
	139   probe:update_sd_lb_stats_L53     <====== 1->0 writes
	129K  probe:add_nr_running_L12
	74    probe:add_nr_running_L13         <====== 0->1 writes
	54K   probe:update_sd_lb_stats_L50     <====== reads

These numbers prove that actual change in the ::overload value is (much) less
frequent: L50 is much larger at ~54,000 accesses vs L53+L13 of 139+74.
