Our nommu_virt_defconfig set SLOB=y and SLAB_MERGE_DEFAULT=n. As of
eb52c0fc23 ("mm: Make SLAB_MERGE_DEFAULT depend on SL[AU]B") it's no
longer necessary to set the second, which appears to never have had any
effect for SLOB=y anyway.
This was suggested by savedefconfig.

Fix a missing prototype warning noticed by the kernel test robot.

Usually palo (the PA-RISC boot loader) will check at boot time if the
machine/firmware was configured to use the serial line (ttyS0, SERIAL_x)
or the graphical display (tty0, graph) as default output device and add
the correct "console=ttyS0" or "console=tty0" Linux kernel parameter to
the kernel command line when starting the Linux kernel.
But the kernel could also have been started via the HP-UX boot loader
or directly in qemu, in which cases the console parameter is missing.
This patch fixes this problem by adding the correct console= parameter
if it's missing in the current kernel command line.

Commit 0f153a1b81 ("usb: chipidea: Set the DT node on the child
device") caused the child device to match on the parent driver
instead of the child's driver since the child's DT node pointer matched.
The worst case result is a loop of the parent driver probing another
instance and creating yet another child device eventually exhausting the
stack. If the child driver happens to match first, then everything works
fine.
A device sharing the DT node should never do DT based driver matching,
so let's simply check of_node_reused in of_match_device() to prevent
that.

Currently, SBI APIs accept a hartmask that is generated from struct
cpumask. Cpumask data structure can hold upto NR_CPUs value. Thus, it
is not the correct data structure for hartids as it can be higher
than NR_CPUs for platforms with sparse or discontguous hartids.
Remove all association between hartid mask and struct cpumask.

The spinwait booting method should only be used for platforms with older
firmware without SBI HSM extension or M-mode firmware because spinwait
method can't support cpu hotplug, kexec or sparse hartid. It is better
to move the entire spinwait implementation to its own config which can
be disabled if required. It is enabled by default to maintain backward

The __cpu_up_stack/task_pointer array is only used for spinwait method
now. The per cpu array based lookup is also fragile for platforms with
discontiguous/sparse hartids. The spinwait method is only used for
M-mode Linux or older firmwares without SBI HSM extension. For general
Linux systems, ordered booting method is preferred anyways to support
cpu hotplug and kexec.
Make sure that __cpu_up_stack/task_pointer is only used for spinwait
method. Take this opportunity to rename it to
__cpu_spinwait_stack/task_pointer to emphasize the purpose as well.

Currently both order booting and spinwait approach uses a per cpu
array to update stack & task pointer. This approach will not work for the
following cases.
1. If NR_CPUs are configured to be less than highest hart id.
2. A platform has sparse hartid.
This issue can be fixed for ordered booting as the booting cpu brings up
one cpu at a time using SBI HSM extension which has opaque parameter
that is unused until now.
Introduce a common secondary boot data structure that can store the stack
and task pointer. Secondary harts will use this data while booting up
to setup the sp & tp.

This is due to the compiler seeing an unsigned long * cast against
something (atomic_t) that is int sized. Replace the cast with the
matching size cast. This results in no change in binary output.
Note that __ll_sc__cmpxchg_case_##name##sz already uses the same
constraint:
[v] "+Q" (*(u##sz *)ptr
Which is why only the LSE form needs updating and not the
LL/SC form, so this change is unlikely to be problematic.

After using io_stop_wc(), drivers reports following compile error when

It is because I missed to add the brackets after io_stop_wc macro. So
let's add the missing brackets.

The variable ret is being assigned a value that is never read. If the

the for-loop is not executed ret is never read. The assignment is

The object-size sanitizer is redundant to -Warray-bounds, and
inappropriately performs its checks at run-time when all information
needed for the evaluation is available at compile-time, making it quite
difficult to use:
https://bugzilla.kernel.org/show_bug.cgi?id=214861
With -Warray-bounds almost enabled globally, it doesn't make sense to
keep this around.

Until recent versions of GCC and Clang, it was not possible to disable
KCOV instrumentation via a function attribute. The relevant function
attribute was introduced in 540540d06e ("kcov: add
__no_sanitize_coverage to fix noinstr for all architectures").
x86 was the first architecture to want a working noinstr, and at the
time no compiler support for the attribute existed yet. Therefore,
commit 0f1441b44e ("objtool: Fix noinstr vs KCOV") introduced the
ability to NOP __sanitizer_cov_*() calls in .noinstr.text.
However, this doesn't work for other architectures like arm64 and s390
that want a working noinstr per ARCH_WANTS_NO_INSTR.
At the time of 0f1441b44e, we didn't yet have ARCH_WANTS_NO_INSTR,
but now we can move the Kconfig dependency checks to the generic KCOV
option. KCOV will be available if:
- architecture does not care about noinstr, OR
- we have objtool support (like on x86), OR
- GCC is 12.0 or newer, OR
- Clang is 13.0 or newer.

Commit b05fbcc36b ("btrfs: disable build on platforms having page size
256K") disabled btrfs for configurations that used a 256kB page size.
However, it did not fully solve the problem because CONFIG_TEST_KMOD
selects CONFIG_BTRFS, which does not account for the dependency. This
results in a Kconfig warning and the failed BUILD_BUG_ON error
returning.
WARNING: unmet direct dependencies detected for BTRFS_FS

- TEST_KMOD [=m] && RUNTIME_TESTING_MENU [=y] && m && MODULES [=y] && NETDEVICES [=y] && NET_CORE [=y] && INET [=y] && BLOCK [=y]
To resolve this, add CONFIG_PAGE_SIZE_LESS_THAN_256KB as a dependency of
CONFIG_TEST_KMOD so there is no more invalid configuration or build

Patch series "Fix CONFIG_TEST_KMOD with 256kB page size".
The kernel test robot reported a build error [1] from a failed assertion
in fs/btrfs/inode.c with a hexagon randconfig that includes
CONFIG_PAGE_SIZE_256KB. This error is the same one that was addressed
by commit b05fbcc36b ("btrfs: disable build on platforms having page
size 256K") but CONFIG_TEST_KMOD selects CONFIG_BTRFS without having the
"page size less than 256kB dependency", which results in the error
reappearing.
The first patch introduces CONFIG_PAGE_SIZE_LESS_THAN_256KB by splitting
it off from CONFIG_PAGE_SIZE_LESS_THAN_64KB, which was introduced in
commit 1f0e290cc5 ("arch: Add generic Kconfig option indicating page
size smaller than 64k") for a similar reason in 5.16-rc3.
The second patch uses that configuration option for CONFIG_BTRFS to
reduce duplication.
The third patch resolves the build error by adding
CONFIG_PAGE_SIZE_LESS_THAN_256KB as a dependency to CONFIG_TEST_KMOD so
that CONFIG_BTRFS does not get enabled under that invalid configuration.
[1]: https://lore.kernel.org/r/202111270255.UYOoN5VN-lkp@intel.com/
This patch (of 3):
btrfs requires a page size smaller than 256kB. To use that dependency
in other places, introduce CONFIG_PAGE_SIZE_LESS_THAN_256KB and reuse
that dependency in CONFIG_PAGE_SIZE_LESS_THAN_64KB.

Some general debugging features like kmemleak, KASAN, lockdep, UBSAN etc
help fix many viruses like a microscope. On the other hand, those
features are scatter around and mixed up with more situational debugging
options making them difficult to consume properly. This cold help
amplify the general debugging/testing efforts and help establish
sensitive default values for those options across the broad. This could
also help different distros to collaborate on maintaining debug-flavored
kernels.
The config is based on years' experiences running daily CI inside the
largest enterprise Linux distro company to seek regressions on
linux-next builds on different bare-metal and virtual platforms. It can
be used for example,
$ make ARCH=arm64 defconfig debug.config
Since KASAN and KCSAN can't be enabled together, we will need to create
a separate one for KCSAN later as well.
