It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.

Before this commit fan_curve_check_present() was trying to not cause
the probe to fail on devices without fan curve control by testing for
known error codes returned by asus_wmi_evaluate_method_buf().
Checking for ENODATA or ENODEV, with the latter being returned by this
function when an ACPI integer with a value of ASUS_WMI_UNSUPPORTED_METHOD
is returned. But for other ACPI integer returns this function just returns
them as is, including the ASUS_WMI_DSTS_UNKNOWN_BIT value of 2.
On the Asus U36SD ASUS_WMI_DSTS_UNKNOWN_BIT gets returned, leading to:
asus-nb-wmi: probe of asus-nb-wmi failed with error 2
Instead of playing whack a mole with error codes here, simply treat all
errors as there not being any fan curves, fixing the driver no longer
loading on the Asus U36SD laptop.

When an iocg is in debt, its inuse weight is owned by debt handling and
should stay at 1. This invariant was broken when determining the amount of
surpluses at the beginning of donation calculation - when an iocg's
hierarchical weight is too low, the iocg is excluded from donation
calculation and its inuse is reset to its active regardless of its
indebtedness, triggering warnings like the following:
WARNING: CPU: 5 PID: 0 at block/blk-iocost.c:1416 iocg_kick_waitq+0x392/0x3a0

As this happens only when an iocg's hierarchical weight is negligible, its

`nf_flowtable_udp_timeout` sysctl option is available only
if CONFIG_NFT_FLOW_OFFLOAD enabled. But infra for this flow
offload UDP timeout was added under CONFIG_NF_FLOW_TABLE
config option. So, if you have CONFIG_NFT_FLOW_OFFLOAD
disabled and CONFIG_NF_FLOW_TABLE enabled, the
`nf_flowtable_udp_timeout` is not present in sysfs.
Please note, that TCP flow offload timeout sysctl option
is present even CONFIG_NFT_FLOW_OFFLOAD is disabled.
I suppose it was a typo in commit that adds UDP flow offload
timeout and CONFIG_NF_FLOW_TABLE should be used instead.

Jaco Kroon reported tcp problems that Eric Dumazet and Neal Cardwell
pinpointed to nf_conntrack tcp_in_window() bug.
tcp trace shows following sequence:
I > R Flags [S], seq 3451342529, win 62580, options [.. tfo [|tcp]>
R > I Flags [S.], seq 2699962254, ack 3451342530, win 65535, options [..]
R > I Flags [P.], seq 1:89, ack 1, [..]
Note 3rd ACK is from responder to initiator so following branch is taken:
} else if (((state->state == TCP_CONNTRACK_SYN_SENT
&& dir == IP_CT_DIR_ORIGINAL)
|| (state->state == TCP_CONNTRACK_SYN_RECV
&& dir == IP_CT_DIR_REPLY))
&& after(end, sender->td_end)) {
... because state == TCP_CONNTRACK_SYN_RECV and dir is REPLY.
This causes the scaling factor to be reset to 0: window scale option
is only present in syn(ack) packets. This in turn makes nf_conntrack
mark valid packets as out-of-window.
This was always broken, it exists even in original commit where
window tracking was added to ip_conntrack (nf_conntrack predecessor)
in 2.6.9-rc1 kernel.
Restrict to 'tcph->syn', just like the 3rd condtional added in
commit 82b72cb94666 ("netfilter: conntrack: re-init state for retransmitted syn-ack").
Upon closer look, those conditionals/branches can be merged:
Because earlier checks prevent syn-ack from showing up in
original direction, the 'dir' checks in the conditional quoted above are
redundant, remove them. Return early for pure syn retransmitted in reply
direction (simultaneous open).

In https://lore.kernel.org/all/87y22uujkm.ffs@tglx/ Thomas
said:
Its's simply wishful thinking that stuff gets fixed because of a
WARN_ONCE(). This has never worked. The only thing which works is to
make stuff fail hard or slow it down in a way which makes it annoying
enough to users to complain.
He was talking about WBINVD. But it made me think about how we use the
split lock detection feature in Linux.
Existing code has three options for applications:
1) Don't enable split lock detection (allow arbitrary split locks)
2) Warn once when a process uses split lock, but let the process
keep running with split lock detection disabled
3) Kill process that use split locks
Option 2 falls into the "wishful thinking" territory that Thomas warns does
nothing. But option 3 might not be viable in a situation with legacy
applications that need to run.
Hence make option 2 much stricter to "slow it down in a way which makes
it annoying".
Primary reason for this change is to provide better quality of service to
the rest of the applications running on the system. Internal testing shows
that even with many processes splitting locks, performance for the rest of
the system is much more responsive.
The new "warn" mode operates like this. When an application tries to
execute a bus lock the #AC handler.
1) Delays (interruptibly) 10 ms before moving to next step.
2) Blocks (interruptibly) until it can get the semaphore
If interrupted, just return. Assume the signal will either
kill the task, or direct execution away from the instruction
that is trying to get the bus lock.
3) Disables split lock detection for the current core
4) Schedules a work queue to re-enable split lock detect in 2 jiffies
5) Returns
The work queue that re-enables split lock detection also releases the
semaphore.
There is a corner case where a CPU may be taken offline while split lock
detection is disabled. A CPU hotplug handler handles this case.
Old behaviour was to only print the split lock warning on the first
occurrence of a split lock from a task. Preserve that by adding a flag to
the task structure that suppresses subsequent split lock messages from that
task.

As functions prototypes regerdless of CONFIG options as well as some
code depend on structures defined in sound/intel-nhlt.h header, move
them out of #define block. This allows to compile code depending on
mentioned header with "depends on ACPI || COMPILE_TEST" in Kconfig.

The IPC message sending can take longer than the default 500ms during
system boot up due to the concurrent loading of different drivers.
Increase the IPC timeout to 1 second to avoid timeout errors due to
Linux load and scheduling.

In smp_85xx_start_cpu() we are passed an address but we're unsure if
it's a real or virtual address, so there's a check to determine that.
The check has an off-by-one in that it tests if the address is greater
than high_memory, but high_memory is the first address of high memory,
so the check should be greater-or-equal.
It seems this has never been a problem in practice, but it also triggers
the DEBUG_VIRTUAL checks in __pa() which we would like to avoid. We can
fix both issues by converting high_memory - 1 to a physical address and
testing against that.
