This allows splicing zeroed pages into a pipe, and allows discarding pages from a pipe by splicing them to /dev/zero. Writing to /dev/zero should have the same effect as writing to /dev/null, and a "splice_write" implementation exists only for /dev/null. (The /dev/zero splice_read implementation could be optimized by pushing references to the global zero page to the pipe, but that's an optimization for another day.) Signed-off-by:

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct hpets.

`strncpy` is deprecated for use on NUL-terminated destination strings [1] and as such we should prefer more robust and less ambiguous string interfaces. We expect `c2dev->name` to be NUL-terminated based on its usage with format strings: | dev_info(c2dev->dev, "C2 port %s removed\n", c2dev->name); Moreover, NUL-padding is _not_ required as c2dev is zero-allocated: | c2dev = kzalloc(sizeof(struct c2port_device), GFP_KERNEL); Considering the above, a suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer without unnecessarily NUL-padding. Let's also drop `C2PORT_NAME_LEN - 1` for `sizeof(dest)` which is more idiomatic strscpy usage.

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to add HAS_IOPORT as dependency for those drivers using them. This was previously done in commit b5c75b68 ("comedi: add HAS_IOPORT dependencies"), but that has been reverted because it made it impossible to select configuration options for several comedi drivers. This is a do-over that avoids that. Since the original patch, modifications have been made to various comedi modules so that they can still be built even if the port I/O functions have not been declared, so the configuration options for building those modules no longer need to depend on HAS_IOPORT. Make the COMEDI_ISA_DRIVERS menu option (which allows configuration options for ISA and PC/104 drivers to be selected) depend on HAS_IOPORT, and also depend on ISA || ISA_BUS || PC104.

In a future patch, the port I/O functions (`inb()`, `outb()`, and friends will only be declared in the `HAS_IOPORT` configuration option is enabled. The amplc_dio200_common module is used by the amplc_dio200 module (for ISA cards) and the amplc_dio200_pci module (for PCI and PCI Express cards). It supports both port I/O and memory-mapped I/O. Port I/O and memory-mapped I/O is confined to the `dio200___read8()`, `dio200___read32()`, `dio200___write8()` and `dio200___write32()` functions. Conditionally compile two versions of those functions. If the `CONFIG_HAS_IOPORT` macro is defined, call either the port I/O or memory mapped I/O functions depending on the `mmio` member of the `struct comedi_device`. If the `CONFIG_HAS_IOPORT` macro is undefined only call the memory-mapped I/O functions. Add a run-time check to `amplc_dio200_common_attach()` to return an error if the device wants to use port I/O when the `CONFIG_HAS_IOPORT` macro is undefined. The changes allow the module to be built even if the port I/O functions have not been declared. Cc: Arnd Bergmann <arnd@kernel.org> Cc: Niklas Schnelle <schnelle@linux.ibm.com> Signed-off-by:

The `dio200_read8()`, `dio200_write8()`, `dio200_read32()` and `dio200_write32()` functions apply a right-shift to the register offset for some devices and then perform the actual register access. Factor the register access part out to new functions `dio200___read8()`, `dio200___write8()`, `dio200___read32()`, and `dio200___write32()`. This will reduce duplicated code in a subsequent patch that will conditionally compile support for port I/O as part of the `HAS_IOPORT` changes.

In a future patch, the port I/O functions (`inb()`, `outb()`, and friends will only be declared in the `HAS_IOPORT` configuration option is enabled. The "ni_mio_common.c" file contains calls to both port I/O functions and memory-mapped I/O functions. The file is `#include`d by "ni_atmio.c", "ni_mio_cs.c", and "ni_pcimio.c" for the ni_atmio, ni_mio_cs, and ni_pcimio modules, respectively. Only "ni_pcimio.c" defines the `PCIDMA` macro before including "ni_mio_common.c" and various bits of code in "ni_mio_common.c" is conditionally compiled according to whether that macro is defined or not. Currently, the port I/O function calls are compiled in regardless of whether the `PCIDMA` macro is defined or not. However, the fact is that the ni_atmio and ni_mio_cs modules will never call the memory-mapped I/O functions, and the ni_pcimio module will never call the port I/O functions. Calls to the port I/O and memory-mapped I/O functions is confined to the `ni_writel()`, `ni_writew()`, `ni_writeb()`, `ni_readl()`, `ni_readw()`, and `ni_readb()` functions which do a run-time test to decide whether to call the port I/O functions or the memory-mapped I/O functions. Conditionally compile two variants of the functions so they only call the port I/O functions if the `PCIDMA` macro is undefined (for the ni_atmio and ni_mio_cs modules), and only call the memory-mapped I/O functions if the `PCIDMA` macro is defined (for the ni_pcimio module). Add a run-time check in the `ni_E_init()` function to return an error if the comedi device has been set up to use port I/O if `PCIDMA` is defined, or has been set up to use memory-mapped I/O if `PCIDMA` is not defined. The changes make it possible to build the ni_pcimio module even if the port I/O functions have not been declared. (The ni_atmio and ni_mio_cs modules do still require the port I/O functions to be declared.) Cc: Arnd Bergmann <arnd@kernel.org> Cc: Niklas Schnelle <schnelle@linux.ibm.com> Signed-off-by:

Comedi drivers can initialize an 8255 subdevice in I/O space by calling `subdev_8255_init()`, or in memory-mapped I/O space by calling `subdev_8255_mm_init()`, or by supplying a call-back function pointer and context to either of those functions. Change it so that a new function `subdev_8255_cb_init()` shall be called instead when supplying a callback function and context, and remove the call-back function parameter from `subdev_8255_init()` and `subdev_8255_mm_init()`. Also rename `subdev_8255_init()` to `subdev_8255_io_init()`. The parameters are changing, so might as well rename it at the same time. Also rename the `regbase` member of `struct subdev_8255_private` to `context` since this holds the context for the call-back function call.

The 8255_pci module supports PCI digital I/O devices from various manufacturers that consist of one or more 8255 Programmable Peripheral Interface chips (or equivalent hardware) to provide their digital I/O ports. Some of the devices use port I/O and some only use memory-mapped I/O. Conditionally compile in support for the devices that need port I/O if and only if the `CONFIG_HAS_IOPORT` macro is defined. Change `pci_8255_auto_attach()` to return an error if the device actually requires port I/O (based on the PCI BAR resource flags) but the `HAS_IOPORT` configuration is not enabled.

`comedi_8254_init()` and `comedi_8254_mm_init()` return `NULL` on failure, but the failure is not necessarily due to lack of memory.

Rework the comedi_8254 module to use a call-back function for register access. This will make it easier to isolate the parts that will depend on the `CONFIG_HAS_IOPORT` macro being defined and also allows the possibility of supplying an external callback function during initialization by a variant of the `comedi_8254_init()` and `comedi_8254_mm_init()` functions, although that has not been implemented yet. The `struct comedi_8254` members have been changed to use a pointer to a callback function and a context of type `unsigned long`. The `comedi_8254_init()` and `comedi_8254_mm_init()` functions use an internal callback function and set the context to the base address of the registers (for `comedi_8254_mm_init()` that involves converting a `void __iomem *` to `unsigned long`). A minor change to `dio200_subdev_8254_offset()` in the amplc_dio200_common module has been made due to the changes in `struct comedi_8254`.

Since commit d8131c29 ("kbuild: remove $(MODLIB)/source symlink"), modules_install does not create the 'source' symlink. Remove the stale code from builddeb and kernel.spec. Signed-off-by:

Drivers must not reference functions marked with __exit as these likely are not available when the code is built-in. There are few creative offenders uncovered for example in ARCH=amd64 allmodconfig builds. So only trigger the section mismatch warning for W=1 builds. The dual rule that drivers must not reference .init.* is implemented since commit 0db25245 ("modpost: don't allow *driver to reference .init.*") which however missed that .exit.* should be handled in the same way. Thanks to Masahiro Yamada and Arnd Bergmann who gave valuable hints to find this improvement. Signed-off-by:
