The interfaces for the fbdev logo are not used outside of the fbdev
module. Hence declare the fbdev logo functions in the internal header
file and remove their symbol exports. Only build the functions if
CONFIG_LOGO has been selected.

Deferred-I/O generator macros generate callbacks for struct fb_ops
that operate on memory ranges in I/O address space or system address
space. Rename the macros to use the _IOMEM_ and _SYSMEM_ infixes of
their underlying helpers. Adapt all users. No functional changes.

Change the infix for fbdev's DMA-memory helpers from _DMA_ to
_DMAMEM_. The helpers perform operations within DMA-able memory,
but they don't perform DMA operations. Naming should make this

Add initializer macros for struct fb_ops for framebuffers in DMA-able
memory areas. Also add a corresponding Kconfig token. As of now, this
is equivalent to system framebuffers and mostly useful for labeling
drivers correctly.
A later patch may add a generic DMA-specific mmap operation. Linux
offers a number of dma_mmap_*() helpers for different use cases.

- Fix some missing-prototype warnings
- Fix user events struct args (did not include size of struct)
When creating a user event, the "struct" keyword is to denote
that the size of the field will be passed in. But the parsing
failed to handle this case.
- Add selftest to struct sizes for user events
- Fix sample code for direct trampolines.
The sample code for direct trampolines attached to handle_mm_fault().
But the prototype changed and the direct trampoline sample code
was not updated. Direct trampolines needs to have the arguments correct
otherwise it can fail or crash the system.
- Remove unused ftrace_regs_caller_ret() prototype.
- Quiet false positive of FORTIFY_SOURCE
Due to backward compatibility, the structure used to save stack traces
in the kernel had a fixed size of 8. This structure is exported to
user space via the tracing format file. A change was made to allow
more than 8 functions to be recorded, and user space now uses the
size field to know how many functions are actually in the stack.
But the structure still has size of 8 (even though it points into
the ring buffer that has the required amount allocated to hold a
full stack. This was fine until the fortifier noticed that the
memcpy(&entry->caller, stack, size) was greater than the 8 functions
and would complain at runtime about it. Hide this by using a pointer
to the stack location on the ring buffer instead of using the address
of the entry structure caller field.
- Fix a deadloop in reading trace_pipe that was caused by a mismatch
between ring_buffer_empty() returning false which then asked to
read the data, but the read code uses rb_num_of_entries() that
returned zero, and causing a infinite "retry".
- Fix a warning caused by not using all pages allocated to store
ftrace functions, where this can happen if the linker inserts a bunch of
"NULL" entries, causing the accounting of how many pages needed
to be off.
- Fix histogram synthetic event crashing when the start event is
removed and the end event is still using a variable from it.
- Fix memory leak in freeing iter->temp in tracing_release_pipe()

[ Fixed ftrace_return_to_handler() to handle CONFIG_HAVE_FUNCTION_GRAPH_RETVAL case ]
Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org>
Ensure running fprobe_exit_handler() has finished before
calling rethook_free() in the unregister_fprobe() so that caller can free
the fprobe right after unregister_fprobe().
unregister_fprobe() ensured that all running fprobe_entry/exit_handler()
have finished by calling unregister_ftrace_function() which synchronizes
RCU. But commit 5f81018753 ("fprobe: Release rethook after the ftrace_ops
is unregistered") changed to call rethook_free() after
unregister_ftrace_function(). So call rethook_stop() to make rethook
disabled before unregister_ftrace_function() and ensure it again.
Here is the possible code flow that can call the exit handler after
unregister_fprobe().
------
CPU1 CPU2
call unregister_fprobe(fp)
...
__fprobe_handler()
rethook_hook() on probed function
unregister_ftrace_function()
return from probed function
rethook hooks
find rh->handler == fprobe_exit_handler
call fprobe_exit_handler()
rethook_free():
set rh->handler = NULL;
return from unreigster_fprobe;
call fp->exit_handler() <- (*)
------
(*) At this point, the exit handler is called after returning from
unregister_fprobe().
This fixes it as following;
------
CPU1 CPU2
call unregister_fprobe()
...
rethook_stop():
set rh->handler = NULL;
__fprobe_handler()
rethook_hook() on probed function
unregister_ftrace_function()
return from probed function
rethook hooks
find rh->handler == NULL
return from rethook
rethook_free()
return from unreigster_fprobe;

Destroying psi trigger in cgroup_file_release causes UAF issues when
a cgroup is removed from under a polling process. This is happening
because cgroup removal causes a call to cgroup_file_release while the
actual file is still alive. Destroying the trigger at this point would
also destroy its waitqueue head and if there is still a polling process
on that file accessing the waitqueue, it will step on the freed pointer:
do_select
vfs_poll
do_rmdir
cgroup_rmdir
kernfs_drain_open_files
cgroup_file_release
cgroup_pressure_release
psi_trigger_destroy
wake_up_pollfree(&t->event_wait)
// vfs_poll is unblocked
synchronize_rcu
kfree(t)
poll_freewait -> UAF access to the trigger's waitqueue head
Patch [1] fixed this issue for epoll() case using wake_up_pollfree(),
however the same issue exists for synchronous poll() case.
The root cause of this issue is that the lifecycles of the psi trigger's
waitqueue and of the file associated with the trigger are different. Fix
this by using kernfs_generic_poll function when polling on cgroup-specific
psi triggers. It internally uses kernfs_open_node->poll waitqueue head
with its lifecycle tied to the file's lifecycle. This also renders the
fix in [1] obsolete, so revert it.

Previously the clients_lock was protecting the clients array against
concurrent addition/removal of clients but was also accessed from IRQ
context. This meant that it had to be a spinlock and that the add() and
remove() callbacks in which clients need to do allocation and take
mutexes can't be called under the clients_lock. To work around this these
callbacks were moved to workqueues. This not only introduced significant
complexity but is also subtly broken in at least one way.
In ism_dev_init() and ism_dev_exit() clients[i]->tgt_ism is used to
communicate the added/removed ISM device to the work function. While
write access to client[i]->tgt_ism is protected by the clients_lock and
the code waits that there is no pending add/remove work before and after
setting clients[i]->tgt_ism this is not enough. The problem is that the
wait happens based on per ISM device counters. Thus a concurrent
ism_dev_init()/ism_dev_exit() for a different ISM device may overwrite
a clients[i]->tgt_ism between unlocking the clients_lock and the
subsequent wait for the work to finnish.
Thankfully with the clients_lock no longer held in IRQ context it can be
turned into a mutex which can be held during the calls to add()/remove()
completely removing the need for the workqueues and the associated
broken housekeeping including the per ISM device counters and the
clients[i]->tgt_ism.

The clients array references all registered clients and is protected by
the clients_lock. Besides its use as general list of clients the clients
array is accessed in ism_handle_irq() to forward ISM device events to
clients.
While the clients_lock is taken in the IRQ handler when calling
handle_event() it is however incorrectly not held during the
client->handle_irq() call and for the preceding clients[] access leaving
it unprotected against concurrent client (un-)registration.
Furthermore the accesses to ism->sba_client_arr[] in ism_register_dmb()
and ism_unregister_dmb() are not protected by any lock. This is
especially problematic as the client ID from the ism->sba_client_arr[]
is not checked against NO_CLIENT and neither is the client pointer
checked.
Instead of expanding the use of the clients_lock further add a separate
array in struct ism_dev which references clients subscribed to the
device's events and IRQs. This array is protected by ism->lock which is
already taken in ism_handle_irq() and can be taken outside the IRQ
handler when adding/removing subscribers or the accessing
ism->sba_client_arr[]. This also means that the clients_lock is no
longer taken in IRQ context.

Pull more ACPI updates from Rafael Wysocki:
"These fix a couple of compiler warnings, refine an ACPI device
enumeration quirk to address a driver regression and clean up code.
Specifics:
- Make acpi_companion_match() return a const pointer and update its
callers accordingly (Andy Shevchenko)
- Move the extern declaration of the acpi_root variable to a header
file so as to address a compiler warning (Andy Shevchenko)
- Address compiler warnings in the ACPI device enumeration code by
adding a missing header file include to it (Ben Dooks)
- Refine the SMB0001 quirk in the ACPI device enumeration code so as
to address an i2c-scmi driver regression (Andy Shevchenko)
- Clean up two pieces of the ACPI device enumeration code (Andy
Shevchenko)"
* tag 'acpi-6.5-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI: scan: Use the acpi_match_acpi_device() helper
ACPI: platform: Move SMB0001 HID to the header and reuse
ACPI: platform: Ignore SMB0001 only when it has resources
ACPI: bus: Introduce acpi_match_acpi_device() helper
ACPI: scan: fix undeclared variable warnings by including sleep.h
ACPI: bus: Constify acpi_companion_match() returned value
ACPI: scan: Move acpi_root to internal header
These are cleanups for architecture specific header files:
- the comments in include/linux/syscalls.h have gone out of sync
and are really pointless, so these get removed
- The asm/bitsperlong.h header no longer needs to be architecture
specific on modern compilers, so use a generic version for newer
architectures that use new enough userspace compilers
- A cleanup for virt_to_pfn/virt_to_bus to have proper type
checking, forcing the use of pointers

"Fix a compiler warning in the J2 probing code and a fix by Sergey
Shtylyov to avoid using IRQ0 on SH3 and SH4 targets. Masahiro Yamada
made some clean-up in the build system to address reports by the 0day
bot.
The most notable changes come from Artur Rojek who addressed a number
of issues in the DMA code, in particular a fix for the DMA channel
offset calculation that was introduced in in 7f47c7189b ("sh: dma:
More legacy cpu dma chainsawing.") in 2012!
Together with another change to correct the number of DMA channels for
each SuperH SoC according to specification, Artur's series unbreaks
the kernel on the SH7709 SoC allowing Linux to boot on the HP Jornada
680 handheld again.
Summary:
- Provide unxlate_dev_mem_ptr() in asm/io.h

When a device-mapper device is passing through the inline encryption
support of an underlying device, calls to blk_crypto_evict_key() take
the blk_crypto_profile::lock of the device-mapper device, then take the
blk_crypto_profile::lock of the underlying device (nested). This isn't
a real deadlock, but it causes a lockdep report because there is only
one lock class for all instances of this lock.
Lockdep subclasses don't really work here because the hierarchy of block
devices is dynamic and could have more than 2 levels.
Instead, register a dynamic lock class for each blk_crypto_profile, and
associate that with the lock.
This avoids false-positive lockdep reports like the following:

In this cycle, we've mainly investigated the zoned block device support along
with patches such as correcting write pointers between f2fs and storage, adding
asynchronous zone reset flow, and managing the number of open zones. Other than
them, f2fs adds another mount option, "errors=x" to specify how to handle when
it detects an unexpected behavior at runtime.
Enhancement:
- support errors=remount-ro|continue|panic mountoption
- enforce some inode flag policies
- allow .tmp compression given extensions
- add some ioctls to manage the f2fs compression
- improve looped node chain flow
- avoid issuing small-sized discard commands during checkpoint
- implement an asynchronous zone reset
Bug fix:
- fix deadlock in xattr and inode page lock
- fix and add sanity check in some error paths
- fix to avoid NULL pointer dereference f2fs_write_end_io() along with put_super

Merge tag 'f2fs-for-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this cycle, we've mainly investigated the zoned block device
support along with patches such as correcting write pointers between
f2fs and storage, adding asynchronous zone reset flow, and managing
the number of open zones.
Other than them, f2fs adds another mount option, "errors=x" to specify
how to handle when it detects an unexpected behavior at runtime.
Enhancements:
- support 'errors=remount-ro|continue|panic' mount option
- enforce some inode flag policies
- allow .tmp compression given extensions
- add some ioctls to manage the f2fs compression
- improve looped node chain flow
- avoid issuing small-sized discard commands during checkpoint
- implement an asynchronous zone reset
Bug fixes:
- fix deadlock in xattr and inode page lock
- fix and add sanity check in some error paths
- fix to avoid NULL pointer dereference f2fs_write_end_io() along
with put_super
- set proper flags to quota files
- fix potential deadlock due to unpaired node_write lock use
- fix over-estimating free section during FG GC
- fix the wrong condition to determine atomic context

These are the first few patches in the Scope-based Resource Management
series that introduce the infrastructure but not any conversions as of
yet.
Adding the infrastructure now allows multiple people to start using them.
Of note is that Sparse will need some work since it doesn't yet
understand this attribute and might have decl-after-stmt issues -- but I
think that's being worked on.

incl_srcpt has the limitation, mentioned in commit b4638af888 ("net:
dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a
MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless
PTP RX timestamping is enabled.
The incl_srcpt option was initially unconditionally enabled, then that
changed with commit 42824463d3 ("net: dsa: sja1105: Limit use of
incl_srcpt to bridge+vlan mode"), then again with b4638af888 ("net:
dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that
it now needs to be always enabled, otherwise the driver does not have a
reliable source of information regarding source_port and switch_id for
link-local traffic (tag_8021q VLANs may be imprecise since now they
identify an entire bridging domain when ports are not standalone).
If we accept that PTP RX timestamping (and therefore, meta frame
generation) is always enabled in hardware, then that limitation could be
avoided and packets with any MAC DA can be properly received, because
meta frames do contain the original bytes from the MAC DA of their
associated link-local packet.
This change enables meta frame generation unconditionally, which also
has the nice side effects of simplifying the switch control path
(a switch reset is no longer required on hwtstamping settings change)
and the tagger data path (it no longer needs to be informed whether to
expect meta frames or not - it always does).

The updates consist of three parts; UAPI update, OHCI driver update, and
several bug fixes.
Firstly, the 1394 OHCI specification defines method to retrieve hardware
time stamps for asynchronous communication, which was previously
unavailable in user space. This change adds new events to the UAPI,
allowing applications to retrieve the time when asynchronous packet are
received and sent. The new events are tested in the breeding edge of
libhinawa and look to work well. The new version of libhinawa will be
released after current merge window is closed.
* https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/
Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI
hardware, This change modernizes the driver by managed resource (devres)
framework.
Lastly, the rest of change is bug fixes for firewire-net and firewire-core.

- Fix missing/incorrect #GP checks on ENCLS
- Use standard mmu_notifier hooks for handling APIC access page
- Drop now unnecessary TR/TSS load after VM-Exit on AMD
- Print more descriptive information about the status of SEV and
SEV-ES during module load
- Add a test for splitting and reconstituting hugepages during and
after dirty logging
- Add support for CPU pinning in demand paging test
- Add support for AMD PerfMonV2, with a variety of cleanups and minor
fixes included along the way
- Add a "nx_huge_pages=never" option to effectively avoid creating NX
hugepage recovery threads (because nx_huge_pages=off can be toggled
at runtime)
- Move handling of PAT out of MTRR code and dedup SVM+VMX code
- Fix output of PIC poll command emulation when there's an interrupt
- Add a maintainer's handbook to document KVM x86 processes,
preferred coding style, testing expectations, etc.
- Misc cleanups, fixes and comments
Generic:
- Miscellaneous bugfixes and cleanups
Selftests:
- Generate dependency files so that partial rebuilds work as
expected"

Fairly small changes this cycle.
* An additional static inline function when kgdb is not enabled to
reduce boilerplate in arch files.
* kdb will now handle input with linefeeds more like carriage return.
This will make little difference for interactive use but can make
it script to use expect-like interaction with kdb.
* A couple of warning fixes.
