Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace code of the following form:
sizeof(struct xt_hashlimit_htable) + sizeof(struct hlist_head) * size
with:
struct_size(hinfo, hash, size)
This code was detected with the help of Coccinelle.

rhashtable_insert_fast() may return an error value when memory
allocation fails, but flow_offload_add() does not check for errors.

Following splat gets triggered when nfnetlink monitor is running while
xtables-nft selftests are running:
net/netfilter/nf_tables_api.c:1272 suspicious rcu_dereference_check() usage!
other info that might help us debug this:
1 lock held by xtables-nft-mul/27006:
#0: 00000000e0f85be9 (&net->nft.commit_mutex){+.+.}, at: nf_tables_valid_genid+0x1a/0x50
Call Trace:
nf_tables_fill_chain_info.isra.45+0x6cc/0x6e0
nf_tables_chain_notify+0xf8/0x1a0
nf_tables_commit+0x165c/0x1740
nf_tables_fill_chain_info() can be called both from dumps (rcu read locked)
or from the transaction path if a userspace process subscribed to nftables
notifications.
In the 'table dump' case, rcu_access_pointer() cannot be used: We do not
hold transaction mutex so the pointer can be NULLed right after the check.
Just unconditionally fetch the value, then have the helper return
immediately if its NULL.
In the notification case we don't hold the rcu read lock, but updates are
prevented due to transaction mutex. Use rcu_dereference_check() to make lockdep
aware of this.

Since commit bc7d811ace4a ("netfilter: nf_ct_h323: Convert
CHECK_BOUND macro to function"), NAT traversal for H.323
doesn't work, failing to parse H323-UserInformation.
nf_h323_error_boundary() compares contents of the bitstring,
not the addresses, preventing valid H.323 packets from being
conntrack'd.
This looks like an oversight from when CHECK_BOUND macro was
converted to a function.
To fix it, stop dereferencing bs->cur and bs->end.

Pull perf fixes from Ingo Molnar:
"I'd like to apologize for this very late pull request: I was dithering
through the week whether to send the fixes, and then yesterday Jiri's
crash fix for a regression introduced in this cycle clearly marked
perf/urgent as 'must merge now'.
Most of the commits are tooling fixes, plus there's three kernel fixes
via four commits:
- race fix in the Intel PEBS code
- fix an AUX bug and roll back a previous attempt
- fix AMD family 17h generic HW cache-event perf counters
The largest diffstat contribution comes from the AMD fix - a new event
table is introduced, which is a fairly low risk change but has a large
linecount"

This patch allows to define the max prescaler by compatible.
To set a large range of timeout, the prescaler should be set
dynamically (from the timeout request) to improve the resolution
in order to have a timeout close to the expected value.

HPWDT_NMI_DECODING depends on HP_WATCHDOG and should be next to it.
This helps menuconfig identify HPWDT_NMI_DECODING as depending on
HP_WATCHDOG.
BCM_KONA_WDT_DEBUG depends on BCM_KONA_WDT which depends on COMPILE_TEST.
Enabling BCM_KONA_WDT_DEBUG without BCM_KONA_WDT does not make sense,
so drop the COMPILE_TEST dependency from it. This also improves
menuconfig, which now properly associates BCM_KONA_WDT_DEBUG with
BCM_KONA_WDT.

Most of the NPCM7XX drivers can be built as modules.
The NPCM7XX watchdog driver code supports building it as
module, but its configuration option is set to bool.
Make itr tristate to actually support modular builds.
This improves consistency with other drivers for the
same platform and enables including the driver in multi-
platform configurations.

Under some circumstances it may be desirable to configure
the watchdog core as module. Enable it.
As part of this change, mark pretimeout governors as depending
on the watchdog core. This is necessary to prevent governors
from being built into the kernel if the watchdog core is built
as module.

Watchdog pretimeout governors were enabled from the default governor
selection using "select". As a result, the default governor was always
built into the kernel, even if no watchdog driver was loaded. By using
"depends on" instead of "select", we are in better control, and the
governors can all be built as modules. At the same time, set the default
configuration option for pretimeout governors to match WATCHDOG_CORE
(meaning all pretimeout governors are by default enabled if pretimeout
support is enabled).
The practical impact of this change is minimal. Previously, selecting
a default governor automatically enabled that governor. Now, a default
governor can only be selected if that governor has been enabled.
Consequently, the order of governor selection is now reversed: The
governor selection is now first, followed by default governor selection.

The Kconfig currently controlling compilation of this code is:
config INTEL_SCU_WATCHDOG
bool "Intel SCU Watchdog for Mobile Platforms"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
We leave the moduleparam.h include since the file does declare some
module parameters, and leaving them as such is currently the easiest
way to remain compatible with existing boot arg use cases.

The Kconfig currently controlling compilation of this code is:

...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_ALIAS is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
We replace module.h with moduleparam.h since the file does actually
declare some module parameters (i.e. boot args for non-modules).

The function is not easy to read and has a problem: -EINVAL is returned
when the module parameter is invalid but the DT parameter is OK.
Refactor the code to have the same pattern of checks for the module
parameter and DT. Further ones can be easily added in the future if the
need arises. The above mentioned problem is fixed, too.
Some documentation is added to describe the different handlings of '0'
for the module parameter and the DT property.
