The functions rio_get_asm() and rio_get_device() are globally exported
but have almost no users in tree. The only user is rio_init_mports()
which invokes it via rio_init().
rio_init() iterates over every registered device and invokes
rio_fixup_device(). It looks like a fixup function which should perform a
"change" to the device but does nothing. It has been like this since its
introduction in commit 394b701ce4fbf ("[PATCH] RapidIO support: core
base") which was merged into v2.6.15-rc1.
Remove rio_init() because the performed fixup function
(rio_fixup_device()) does nothing. Remove rio_get_asm() and
rio_get_device() which have no callers now.

This new test ensures that fortified strscpy has the same behavior than
vanilla strscpy (e.g. returning -E2BIG when src content is truncated).
Finally, it generates a crash at runtime because there is a write overflow
in destination string.

Add code to test both:
- runtime detection of the overrun of a structure. This covers the
__builtin_object_size(x, 0) case. This test is called FORTIFY_OBJECT.
- runtime detection of the overrun of a char array within a structure.
This covers the __builtin_object_size(x, 1) case which can be used
for some string functions. This test is called FORTIFY_SUBOBJECT.

Pull spi updates from Mark Brown:
"The big change this release has been some excellent work from Lukas
Wunner which closes a bunch of holes in the cleanup paths for drivers,
mainly introduced as a result of devm conversions causing bad
interactions with the support SPI has for allocating the bus and
driver data together.
Together with some of the other work done it feels like we've turned
the corner on several long standing pain points with the API.
Summary:
- Many cleanups around probe/remove and error handling from Lukas
Wunner and Uwe Kleine-König, and further fixes around PM from Zhang
Qilong.
- Provide a mask for which bits of the mode can safely be configured
by drivers and use that to fix an issue with the ADS7846 driver.
- Documentation of the expected interactions between SPI and GPIO
level chip select polarity configuration from H. Nikolaus Schaller,
hopefully we're pretty much at the end of sorting out the
interactions there. Thanks to Nikolaus, Sven Van Asbroeck and Linus
Walleij for this.
- DMA support for Allwinner sun6i controllers.
- Support for Canaan K210 Designware implementations and Intel Adler
Lake"

many smaller improvements
- TLS: support CHACHA20-POLY1305 cipher
- seg6: add support for SRv6 End.DT4/DT6 behavior
- sctp: Implement RFC 6951: UDP Encapsulation of SCTP
- ppp_generic: add ability to bridge channels directly
- bridge: Connectivity Fault Management (CFM) support as is defined
in IEEE 802.1Q section 12.14.
Drivers:
- mlx5: make use of the new auxiliary bus to organize the driver
internals
- mlx5: more accurate port TX timestamping support

Refactor:
- a few pieces of in_interrupt() cleanup work from Sebastian Andrzej
Siewior
- phy: add support for shared interrupts; get rid of multiple driver
APIs and have the drivers write a full IRQ handler, slight growth
of driver code should be compensated by the simpler API which also
allows shared IRQs
- add common code for handling netdev per-cpu counters
- move TX packet re-allocation from Ethernet switch tag drivers to a
central place
- improve efficiency and rename nla_strlcpy
- number of W=1 warning cleanups as we now catch those in a patchwork
build bot
Old code removal:

From the beginning, the zram block device always enabled CRYPTO_LZO,
since lzo-rle is hardcoded as the fallback compression algorithm. As a
consequence, on systems where another compression algorithm is chosen
(e.g. CRYPTO_ZSTD), the lzo kernel module becomes unused, while still
having to be built/loaded.
This patch removes the hardcoded lzo-rle dependency and allows the user
to select the default compression algorithm for zram at build time. The
previous behaviour is kept, as the default algorithm is still lzo-rle.

Currently, zram supports the stat via /sys/block/zram/mm_stat to represent
how many of incompressible pages are stored at the moment but it couldn't
show how many times incompressible pages were wrote down since zram set
up. It's also good indication to see how zram is effective in the system.

There is demand to writeback specific process pages to backing store
instead of all idles pages in the system due to storage wear out concerns
and to launching latency of apps which are most of the time idle but are
critical for resume latency.
This patch extends the writeback knob to support a specific page
writeback.

CONFIG_PAGE_POISONING_NO_SANITY skips the check on page alloc whether the
poison pattern was corrupted, suggesting a use-after-free. The motivation
to introduce it in commit 8823b1dbc05f ("mm/page_poison.c: enable
PAGE_POISONING as a separate option") was to simply sanitize freed pages,
optimally together with CONFIG_PAGE_POISONING_ZERO.
These days we have an init_on_free=1 boot option, which makes this use
case of page poisoning redundant. For sanitizing, writing zeroes is
sufficient, there is pretty much no benefit from writing the 0xAA poison
pattern to freed pages, without checking it back on alloc. Thus, remove
this option and suggest init_on_free instead in the main config's help.

Commit 11c9c7edae06 ("mm/page_poison.c: replace bool variable with static
key") changed page_poisoning_enabled() to a static key check. However,
the function is not inlined, so each check still involves a function call
with overhead not eliminated when page poisoning is disabled.
Analogically to how debug_pagealloc is handled, this patch converts
page_poisoning_enabled() back to boolean check, and introduces
page_poisoning_enabled_static() for fast paths. Both functions are
inlined.
The function kernel_poison_pages() is also called unconditionally and does
the static key check inside. Remove it from there and put it to callers.
Also split it to two functions kernel_poison_pages() and
kernel_unpoison_pages() instead of the confusing bool parameter.
Also optimize the check that enables page poisoning instead of
debug_pagealloc for architectures without proper debug_pagealloc support.
Move the check to init_mem_debugging_and_hardening() to enable a single
static key instead of having two static branches in
page_poisoning_enabled_static().

Building lkdtm with KASAN and Clang 11 or later results in the following
error when attempting to load the module:
kernel tried to execute NX-protected page - exploit attempt? (uid: 0)
BUG: unable to handle page fault for address: ffffffffc019cd70
#PF: supervisor instruction fetch in kernel mode
#PF: error_code(0x0011) - permissions violation
...
RIP: 0010:asan.module_ctor+0x0/0xffffffffffffa290 [lkdtm]
...
Call Trace:
do_init_module+0x17c/0x570
load_module+0xadee/0xd0b0

do_syscall_64+0x34/0x50
entry_SYSCALL_64_after_hwframe+0x44/0xa9
The reason is that rodata.o generates a dummy function that lives in
.rodata to validate that .rodata can't be executed; however, Clang 11 adds
KASAN globals support by generating module constructors to initialize
globals redzones. When Clang 11 adds a module constructor to rodata.o, it
is also added to .rodata: any attempt to call it on initialization results
in the above error.
Therefore, disable KASAN instrumentation for rodata.o.
