A simple conversion of alsa-driver-api document from DocBook to ReST.
It's moved to the new Documentation/sound/kernel-api subdirectory that

The GPL legal note was removed, as it's superfluous (and doesn't fit
with ReST kernel docs pretty well).

dw_pcie_iatu_unroll_enabled() reads a dbi_base register. Reading any
dbi_base register before pp->ops->host_init has been called causes
"imprecise external abort" on platforms like ARTPEC-6, where the PCIe
module is disabled at boot and first enabled in pp->ops->host_init. Move
dw_pcie_iatu_unroll_enabled() to dw_pcie_setup_rc(), since it is after
pp->ops->host_init, but before pp->iatu_unroll_enabled is actually used.

Pull parisc updates from Helge Deller:
"The first three patches are trivial and add some required KERN_CONT,
ignore the new pkey syscalls on parisc and use the LINUX_GATEWAY_ADDR
define instead of hardcoded values.
The two patches from Dave Anglin are important.
The first one avoids trashing the sr2 and sr3 space registers in the
Light-weight syscall path. Especially the usage of sr3 is critical
since it may get trashed by the interrupt handler.
The second patch is even more important and tagged for stable series.
It protects one critical section in the syscall entry path by
disabling local interrupts. Without disabling interrupts, the sr7
space register may not be in sync with the current stack setup and
thus an incoming hardware interrupt may destroy memory in random
userspace areas"

Race condition between registering an I2C device driver and
deregistering an I2C adapter device which is assumed to manage that
I2C device may lead to a NULL pointer dereference due to the
uninitialized list head of driver clients.
The root cause of the issue is that the I2C bus may know about the
registered device driver and thus it is matched by bus_for_each_drv(),
but the list of clients is not initialized and commonly it is NULL,
because I2C device drivers define struct i2c_driver as static and
clients field is expected to be initialized by I2C core:
i2c_register_driver() i2c_del_adapter()
driver_register() ...
bus_add_driver() ...
... bus_for_each_drv(..., __process_removed_adapter)
... i2c_do_del_adapter()
... list_for_each_entry_safe(..., &driver->clients, ...)
INIT_LIST_HEAD(&driver->clients);
To solve the problem it is sufficient to do clients list head
initialization before calling driver_register().
The problem was found while using an I2C device driver with a sluggish
registration routine on a bus provided by a physically detachable I2C
master controller, but practically the oops may be reproduced under
the race between arbitraty I2C device driver registration and managing
I2C bus device removal e.g. by unbinding the latter over sysfs:
% echo 21a4000.i2c > /sys/bus/platform/drivers/imx-i2c/unbind
