Previously, one-element and zero-length arrays were treated as true
flexible arrays, even though they are actually "fake" flex arrays.
The __randomize_layout would leave them untouched at the end of the
struct, similarly to proper C99 flex-array members.
However, this approach changed with commit 1ee60356c2 ("gcc-plugins:
randstruct: Only warn about true flexible arrays"). Now, only C99
flexible-array members will remain untouched at the end of the struct,
while one-element and zero-length arrays will be subject to randomization.
Fix a `__randomize_layout` crash in `struct neighbour` by transforming
zero-length array `primary_key` into a proper C99 flexible-array member.

TC ingress policer rules depends on interface receive queue
contexts since the bandwidth profiles are attached to RQ
contexts. When an interface is brought down all the queue
contexts are freed. This in turn frees bandwidth profiles in
hardware causing ingress police rules non-functional after
the interface is brought up. Fix this by applying all the ingress
police rules config to hardware in otx2_open. Also allow
adding ingress rules only when interface is running
since no contexts exist for the interface when it is down.

Commit 34539b442b ("bus: ti-sysc: Flush posted write on enable before
reset") caused a regression reproducable on omap4 duovero where the ISS
target module can produce interconnect errors on boot. Turns out the
registers are not accessible until after a delay for devices needing
a ti,sysc-delay-us value.
Let's fix this by flushing the posted write only after the reset delay.
We do flushing also for ti,sysc-delay-us using devices as that should
trigger an interconnect error if the delay is not properly configured.
Let's also add some comments while at it.

The rtas_read_config() and rtas_write_config() functions in
kernel/rtas_pci.c have external linkage and two users in arch/powerpc:
the rtas_pci code itself and the pseries platform's "enhanced error
handling" (EEH) support code.
The prototypes for these functions in asm/ppc-pci.h have until now
been guarded by CONFIG_EEH since the only external caller is the
pseries EEH code. However, this presumably has always generated
warnings when built with !CONFIG_EEH and -Wmissing-prototypes:
arch/powerpc/kernel/rtas_pci.c:46:5: error: no previous prototype for
function 'rtas_read_config' [-Werror,-Wmissing-prototypes]
46 | int rtas_read_config(struct pci_dn *pdn, int where,

function 'rtas_write_config' [-Werror,-Wmissing-prototypes]
98 | int rtas_write_config(struct pci_dn *pdn, int where,
int size, u32 val)
The introduction of commit c6345dfa6e3e ("Makefile.extrawarn: turn on
missing-prototypes globally") forces the issue.
The efika and chrp platform code have (static) functions with the same
names but different signatures. We may as well eliminate the potential
for conflicts and confusion by renaming the globally visible versions
as their prototypes get moved out of the CONFIG_EEH-guarded region;
their current names are too generic anyway. Since they operate on
objects of the type 'struct pci_dn *', give them the slightly more
verbose prefix "rtas_pci_dn_" and fix up all the call sites.

Configuring the required OPP was never properly implemented, we just
took an exception for genpds and configured them directly, while leaving
out all other required OPP types.
Now that a standard call to dev_pm_opp_set_opp() takes care of
configuring the opp->level too, the special handling for genpds can be
avoided by simply calling dev_pm_opp_set_opp() for the required OPPs,
which shall eventually configure the corresponding level for genpds.
This also makes it possible for us to configure other type of required
OPPs (no concrete users yet though), via the same path. This is how
other frameworks take care of parent nodes, like clock, regulators, etc,
where we recursively call the same helper.
In order to call dev_pm_opp_set_opp() for the virtual genpd devices,
they must share the OPP table of the genpd. Call _add_opp_dev() for them
to get that done.
This commit also extends the struct dev_pm_opp_config to pass required
devices, for non-genpd cases, which can be used to call
dev_pm_opp_set_opp() for the non-genpd required devices.

There are two genpd (as required-opp) cases that we need to handle,
devices with a single genpd and ones with multiple genpds.
The multiple genpds case is clear, where the OPP core calls
dev_pm_domain_attach_by_name() for them and uses the virtual devices
returned by this helper to call dev_pm_domain_set_performance_state()
later to change the performance state.
The single genpd case however requires special handling as we need to
use the same `dev` structure (instead of a virtual one provided by genpd
core) for setting the performance state via
dev_pm_domain_set_performance_state().
As we move towards more generic code to take care of the required OPPs,
where we will recursively call dev_pm_opp_set_opp() for all the required
OPPs, the above special case becomes a problem.
It doesn't make sense for a device's DT entry to have both "opp-level"
and single "required-opps" entry pointing to a genpd's OPP, as that
would make the OPP core call dev_pm_domain_set_performance_state() for
two different values for the same device structure. And so we can reuse
the 'opp->level" field in such a case and call _set_opp_level() for the
device.

to AC timing control register. With this operation, We
change DOAISE to 0, and force a much more aggressive
timing. The timing is even unable to form a working

mddev_lock()

pers->hot_remove_disk();
rcu_assign_pointer(conf->rdev, NULL);
synchronize_rcu();
mddev_unlock()
// triggered by daemon
mddev_lock()
rdev_removeable();
synchronize_rcu(); -> this can't protect accessing rdev from conf
pers->hot_remove_disk();

6. md_kick_rdev_from_array() remove rdev from mddev->disks;
mddev_lock()

synchronize_rcu();
list_add(&rdev->same_set, &mddev->deleting)

There are two separate rcu protection for rdev, and this pathset remove
the protection of conf(step 3 and 5), because it's safe to access rdev
from conf in following cases:
- If 'reconfig_mutex' is held, because rdev can't be added or rmoved to
conf;
- If there is normal IO inflight, because mddev_suspend() will wait for
IO to be done and prevent rdev to be added or removed to conf;
- If sync thread is running, because remove_and_add_spares() can only be
called from daemon thread when sync thread is done, and
'MD_RECOVERY_RUNNING' is also checked for ioctl/sysfs;
- if any spinlock or rcu_read_lock() is held, because synchronize_rcu()
from step 6 prevent rdev to be freed until spinlock is released or
rcu_read_unlock();

The rpm-pkg and deb-pkg targets have transitioned to using 'git archive'
for tarball creation.
Although the old cmd_src_tar is still used by snap-pkg, there is no need
to pack and unpack a tarball solely for passing the source to snapcraft.
Instead, you can use 'source-type: local' to tell the source location to
snapcraft.

It is done for the same reasons as 4243afdb93 does it for builddeb:
always runs make modules to install modules.builtin* files, which are
needed for e.g. initramfs-tools or LTP testing tool.

The shell variable $dirs is not used any more since 1fc9095846
("kbuild: tar-pkg: use tar rules in scripts/Makefile.package"),
therefore remove it".

Make the while-loop code a little more readable.
The gain is that "CONFIG_FOO" without '=' is warned as unexpected data.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
Currently, any string starting "is not set" disables a CONFIG option.
For example, "# CONFIG_FOO is not settled down" is accepted as valid
input, functioning the same as "# CONFIG_FOO is not set". It is a
long-standing oddity.
Check the line against the exact pattern "is not set".

Currently, newline characters are stripped away in multiple places
on the caller.
Doing that in the callee is helpful for further cleanups.

Kconfig accepts both "# CONFIG_FOO is not set" and "CONFIG_FOO=n" as
a valid input, but conf_read_simple() duplicates similar code to handle
them. Factor out the common code.

The 'else' arm here is unreachable in practical use cases.
include/config/auto.conf does not include "# CONFIG_... is not set"
line unless it is manually hacked.
Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
Currently, when an input line starts with '#', (line + 2) is passed to
memcmp() without checking line[1].
It means that line[1] can be any arbitrary character. For example,
"#KCONFIG_FOO is not set" is accepted as valid input, functioning the
same as "# CONFIG_FOO is not set".
More importantly, this can potentially lead to a buffer overrun if
line[1] == '\0'. It occurs if the input only contains '#', as
(line + 2) points to an uninitialized buffer.
Check line[1], and skip the line if it is not a space.

xrealloc() never returns NULL as it is checked in the callee.
This is a left-over of commit d717f24d8c ("kconfig: add xrealloc()
helper").

The long version --rules-file and --jobs are available since 1.18.8
while their short analogues -R and -j have been added since 1.14.7.
The option --rules-file the way it works currently was introduced in the
commit 5cd52673aabdf5eaa58181972119a41041fc85f2 of dpkg dated 23.07.18
with the following changelog entry:
* Fix dpkg-buildpackage option --rules-file parsing. It was trying to parse
it as --rules-target, which due to the ordering was a no-op.
The current behavior of the long version --rules-file is guaranteed to
be in use starting 1.19.1 and might cause build failures for some
versions newer than 1.18.8 even in spite of being documented that way.

When a user-supplied value is out of range, (NEW) and an incorrect default
value are shown.
[Test Kconfig]
config FOO
int "foo"
range 10 20
[Test .config]
CONFIG_FOO=30
[Result without this fix]
$ make config
*
* Main menu
*
foo (FOO) [10] (NEW)
[Result with this fix]
$ make config
*
* Main menu
*
foo (FOO) [20]
Currently, the SYMBOL_DEF_USER is cleared if the user input does not
reside within the range. Kconfig forgets the initial value 30, and
prints (NEW) and an incorrect default [10].
Kconfig should remember the user's input. The default should be [20]
because the user's input, 30, is closer to the upper limit of the range.
Please note it will not show up in "make oldconfig" because it is no
longer considered as a new symbol. It also fixes the inconsistent
behavior in listnewconfig/helpnewconfig.

getopt_long() is used by various tools in the kernel (e.g. Kconfig).
It should be fine to use it all the time.
