timespec64_ns() prevents multiplication overflows by comparing the seconds
value of the timespec to KTIME_SEC_MAX. If the value is greater or equal it
returns KTIME_MAX.
But that check casts the signed seconds value to unsigned which makes the
comparision true for all negative values and therefore return wrongly
KTIME_MAX.
Negative second values are perfectly valid and required in some places,
e.g. ptp_clock_adjtime().
Remove the cast and add a check for the negative boundary which is required
to prevent undefined behaviour due to multiplication underflow.

As noted in the "Deprecated Interfaces, Language Features, Attributes, and
Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead to
values wrapping around and a smaller allocation being made than the caller
was expecting. Using those allocations could lead to linear overflows of
heap memory and other misbehaviors.
In this case this is not actually dynamic sizes: both sides of the
multiplication are constant values. However it is best to refactor this
anyway, just to keep the open-coded math idiom out of code.
So, use the purpose specific kcalloc() function instead of the argument
size * count in the kzalloc() function.
Also, remove the unnecessary initialization of the sqp_tbl variable since
it is set a few lines later.

mlx5_ib_update_xlt() and the logic was changed to enable better OOM
handling. Sadly this change introduced a miscalculation of the number of
entries that were actually allocated when under memory pressure where it
can actually become 0 which on s390 lets dma_map_single() fail.
It can also lead to corruption of the free pages list when the wrong
number of entries is used in the calculation of sg->length which is used
as argument for free_pages().
Fix this by using the allocation size instead of misusing get_order(size).

commit 5f58591323 ("net: stmmac: delete the eee_ctrl_timer after
napi disabled"), this patch tries to fix system hang caused by eee_ctrl_timer,
unfortunately, it only can resolve it for system reboot stress test. System
hang also can be reproduced easily during system suspend/resume stess test
when mount NFS on i.MX8MP EVK board.
In stmmac driver, eee feature is combined to phylink framework. When do
system suspend, phylink_stop() would queue delayed work, it invokes
stmmac_mac_link_down(), where to deactivate eee_ctrl_timer synchronizly.
In above commit, try to fix issue by deactivating eee_ctrl_timer obviously,
but it is not enough. Looking into eee_ctrl_timer expire callback
stmmac_eee_ctrl_timer(), it could enable hareware eee mode again. What is
unexpected is that LPI interrupt (MAC_Interrupt_Enable.LPIEN bit) is always
asserted. This interrupt has chance to be issued when LPI state entry/exit
from the MAC, and at that time, clock could have been already disabled.
The result is that system hang when driver try to touch register from
interrupt handler.
The reason why above commit can fix system hang issue in stmmac_release()
is that, deactivate eee_ctrl_timer not just after napi disabled, further
after irq freed.
In conclusion, hardware would generate LPI interrupt when clock has been
disabled during suspend or resume, since hardware is in eee mode and LPI
interrupt enabled.
Interrupts from MAC, MTL and DMA level are enabled and never been disabled
when system suspend, so postpone clocks management from suspend stage to
noirq suspend stage should be more safe.

There is an off-by-one problem in ipa_table_init_add(), when
initializing filter tables.
In that function, the number of filter table entries is determined
based on the number of set bits in the filter map. However that
count does *not* include the extra "slot" in the filter table that
holds the filter map itself. Meanwhile, ipa_table_addr() *does*
include the filter map in the memory it returns, but because the
count it's provided doesn't include it, it includes one too few
table entries.
Fix this by including the extra slot for the filter map in the count
computed in ipa_table_init_add().
Note: ipa_filter_reset_table() does not have this problem; it resets
filter table entries one by one, but does not overwrite the filter
bitmap.

Currently changes to the advertising state via ethtool do not cause any
reselection of the configured interface mode after the SFP is already
inserted and initially configured.
While it is not typical to change the advertised link modes for an
interface using an SFP in certain use cases it is desirable. In the case
of a SFP port that is capable of handling both SFP and SFP+ modules it
will automatically select between 1G and 10G modes depending on the
supported mode of the SFP. However if the SFP module is capable of
working in multiple modes (e.g. a SFP+ DAC that can operate at 1G or
10G), one end of the cable may be attached to a SFP 1000base-x port thus
the SFP+ end must be manually configured to the 1000base-x mode in order
for the link to be established.
This change causes the ethtool setting of advertised mode changes to
reselect the interface mode so that the link can be established.
Additionally when a module is inserted the advertising mode is reset to
match the supported modes of the module.

The cross-product of the kernel's supported toolchains, architectures,
and configuration options is large. So large, that it's generally
accepted to be infeasible to enumerate and build+test them all
(many compile-testers rely on randomly generated configs).
Without the possibility to enumerate all possible combinations of
toolchains, architectures, and configuration options, it is inevitable
that compiler warnings in this space exist.
With -Werror, this means that an innumerable set of kernels are now
broken, yet had been perfectly usable before (confused compilers, code
with warnings unused, or luck).
Distributors will necessarily pick a point in the toolchain X arch X
config space, and if unlucky, will have a broken build. Granted, those
will likely disable CONFIG_WERROR and move on.
The kernel's default configuration is unlikely to be suitable for all
users, but it's inappropriate to force many users to set CONFIG_WERROR=n.
This also holds for CI systems which are focused on runtime testing,
where the odd warning in some subsystem will disrupt testing of the rest
of the kernel. Many of those runtime-focused CI systems run tests or
fuzz the kernel using runtime debugging tools. Runtime testing of
different subsystems can proceed in parallel, and potentially uncover
serious bugs; halting runtime testing of the entire kernel because of
the odd warning (now error) in a subsystem or driver is simply
inappropriate.
Therefore, runtime-focused CI systems will likely choose CONFIG_WERROR=n
as well.
The appropriate usecase for -Werror is therefore compile-test focused
builds (often done by developers or CI systems).
Reflect this in the Kconfig option by making the default value of WERROR
match COMPILE_TEST.
