The caller of console_is_usable() usually needs @console->flags for its own checks. Rather than having console_is_usable() read its own copy, make the caller pass in the @flags. This also ensures that the caller saw the same @flags value.

The headers kernel.h, serial_core.h, and console.h allow for the definitions of many types and functions from other headers.

Currently the port->lock wrappers uart_port_lock(), uart_port_unlock() (and their variants) only lock/unlock the spin_lock. If the port is an nbcon console that has implemented the write_atomic() callback, the wrappers must also acquire/release the console context and mark the region as unsafe. This allows general port->lock synchronization to be synchronized against the nbcon write_atomic() callback. Note that __uart_port_using_nbcon() relies on the port->lock being held while a console is added and removed from the console list (i.e. all uart nbcon drivers *must* take the port->lock in their device_lock() callbacks).

Provide functions nbcon_device_try_acquire() and nbcon_device_release() which will try to acquire the nbcon console ownership with NBCON_PRIO_NORMAL and mark it unsafe for handover/takeover. These functions are to be used together with the device-specific locking when performing non-printing activities on the console device. They will allow synchronization against the atomic_write() callback which will be serialized, for higher priority contexts, only by acquiring the console context ownership. Pitfalls: The API requires to be called in a context with migration disabled because it uses per-CPU variables internally. The context is set unsafe for a takeover all the time. It guarantees full serialization against any atomic_write() caller except for the final flush in panic() which might try an unsafe takeover.

It was not clear when exactly console_srcu_read_flags() must be used vs. directly reading @console->flags. Refactor and clarify that console_srcu_read_flags() is only needed if the console is registered or the caller is in a context where the registration status of the console may change (due to another context). The function requires the caller holds @console_srcu, which will ensure that the caller sees an appropriate @flags value for the registered console and that exit/cleanup routines will not run if the console is in the process of unregistration.

Introduce uart_port_set_cons() as a wrapper to set @cons of a uart_port. The wrapper sets @cons under the port lock in order to prevent @cons from disappearing while another context is holding the port lock. This is necessary for a follow-up commit relating to the port lock wrappers, which rely on @cons not changing between lock and unlock.

It will be necessary at times for the uart nbcon console drivers to acquire the port lock directly (without the additional nbcon functionality of the port lock wrappers). These are special cases such as the implementation of the device_lock()/device_unlock() callbacks or for internal port lock wrapper synchronization. Provide low-level variants __uart_port_lock_irqsave() and __uart_port_unlock_irqrestore() for this purpose.

Console drivers typically have to deal with access to the hardware via user input/output (such as an interactive login shell) and output of kernel messages via printk() calls. They use some classic driver-specific locking mechanism in most situations. But console->write_atomic() callbacks, used by nbcon consoles, are synchronized only by acquiring the console context. The synchronization via the console context ownership is possible only when the console driver is registered. It is when a particular device driver is connected with a particular console driver. The two synchronization mechanisms must be synchronized between each other. It is tricky because the console context ownership is quite special. It might be taken over by a higher priority context. Also CPU migration must be disabled. The most tricky part is to (dis)connect these two mechanisms during the console (un)registration. Use the driver-specific locking callbacks: device_lock(), device_unlock(). They allow taking the device-specific lock while the device is being (un)registered by the related console driver. For example, these callbacks lock/unlock the port lock for serial port drivers. Note that the driver-specific locking is only needed during (un)register if it is an nbcon console with the write_atomic() callback implemented. If write_atomic() is not implemented, the driver should never attempt to access the hardware without first acquiring its driver-specific lock.

Console drivers typically must deal with access to the hardware via user input/output (such as an interactive login shell) and output of kernel messages via printk() calls. To provide the necessary synchronization, usually some driver-specific locking mechanism is used (for example, the port spinlock for uart serial consoles). Until now, usage of this driver-specific locking has been hidden from the printk-subsystem and implemented within the various console callbacks. However, nbcon consoles would need to use it even in the generic code. Add device_lock() and device_unlock() callback which will need to get implemented by nbcon consoles. The callbacks will use whatever synchronization mechanism the driver is using for itself. The minimum requirement is to prevent CPU migration. It would allow a context friendly acquiring of nbcon console ownership in non-emergency and non-panic context.

The return value of write_atomic() does not provide any useful information. On the contrary, it makes things more complicated for the caller to appropriately deal with the information. Change write_atomic() to not have a return value. If the message did not get printed due to loss of ownership, the caller will notice this on its own. If ownership was not lost, it will be assumed that the driver successfully printed the message and the sequence number for that console will be incremented.

If a non-boot console is registering and boot consoles exist, the consoles are flushed before being unregistered. This allows the non-boot console to continue where the boot console left off. If for whatever reason flushing fails, the lowest seq found from any of the enabled boot consoles is used. Until now con->seq was checked. However, if it is an nbcon boot console, the function nbcon_seq_read() must be used to read seq because con->seq is not updated for nbcon consoles. Check if it is an nbcon boot console and if so call nbcon_seq_read() to read seq. Also, avoid usage of con->seq as temporary storage of the starting record. Instead, rename console_init_seq() to get_init_console_seq() and just return the value. For nbcon consoles set the sequence via nbcon_seq_force(), for legacy consoles set con->seq. The cleaned design should make sure that the value stays and is set before the console is added to the console list. It also unifies the sequence number initialization for legacy and nbcon consoles.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page zeroing (because it can be used to change partial page contents). So fuse_notify_store() must be more careful to fully initialize page contents (including parts of the page that are beyond end-of-file) before marking the page uptodate. The current code can leave beyond-EOF page contents uninitialized, which makes these uninitialized page contents visible to userspace via mmap(). This is an information leak, but only affects systems which do not enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the corresponding kernel command line parameter).

Pull arm64 fixes from Catalin Marinas: - Fix the arm64 __get_mem_asm() to use the _ASM_EXTABLE_##type##ACCESS() macro instead of the *_ERR() one in order to avoid writing -EFAULT to the value register in case of a fault - Initialise all elements of the acpi_early_node_map[] to NUMA_NO_NODE. Prior to this fix, only the first element was initialised - Move the KASAN random tag seed initialisation after the per-CPU areas have been initialised (prng_state is __percpu) * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Fix KASAN random tag seed initialization arm64: ACPI: NUMA: initialize all values of acpi_early_node_map to NUMA_NO_NODE arm64: uaccess: correct thinko in __get_mem_asm()
