staging: comedi: always set hw_dev during auto-config
Auto-configuration (auto-attachment) of USB and PCI comedi devices all
goes through `comedi_auto_config_helper()`. That is a good place to set
the comedi device's `hw_dev` pointer to the hardware `struct device` via
a call to `comedi_set_hw_dev(comedi_device, hardware_device)` as it may
obviate the need for the low-level comedi driver to make this call.

The remaining comedi drivers that still have a devpriv macro
are all pretty straight forward for removing the devpriv
macro.
This macro relies on a local variable having a specific name.
Remove its use by replacing it with a local variable where
used.
The inline function alloc_private(), used to kzalloc the
dev->private memory, returns non-zero if there is an error.
Fix all the alloc_private() calls accordingly and remove any
kernel messages or obvious comments that still exist in the
drivers. Leave a comment in the skel driver.

Now that we have the infrastructure to use the regular function in place
and all existing users are converted, remove the map and unmap callbacks
from the ipack_bus_device->ops.
Previously the *_phys fields were of type ipack_addr_space, which use
void pointers to refer to memory addresses. Since the *_phys fields
refer to unmapped memory, this is not correct. Introduce a new struct
ipack_region (which uses phys_addr_t to refer to the start of a region)
and use that as a replacement for struct ipack_addr_space.
struct ipack_region is defined in ipack.h because it is planned to later
expose the physical addressed to the IPack Module drivers.

ipack_device_register() is no longer creating the struct ipack_device
but only registering it. Instead of releasing memory directly the new

x86, boot: Explicitly include autoconf.h for hostprogs
The hostprogs need access to the CONFIG_* symbols found in

the header include path sets and add uapi/ header directories") replaced
$(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary

This has the undesirable effect of breaking the EFI boot stub because
the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is
never compiled.
It should also be noted that because $(USERINCLUDE) isn't exported by

"The patches contained herein do the following:
(1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked
this with Paul Mackerras before I created the patch and he suggested some
extra bits to unexport.
(2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace
applicable, and remove from the UAPI that part of linux/fs.h that was the
reason for linux/blk_types.h being exported in the first place. I
discussed this with Jens Axboe before creating the patch.
(3) The big patch of the series to disintegrate include/linux/*.h as a unit.
This could be split up, though there would be collisions in moving stuff
between the two Kbuild files when the parts are merged as that file is
sorted alphabetically rather than being grouped by subsystem.
Of this set of headers, 17 files have changed in the UAPI exported region
since the 4th and only 8 since the 9th so there isn't much change in this
area - as one might expect.
It should be pretty obvious and straightforward if it does come to fixing
up: stuff in __KERNEL__ guards stays where it is and stuff outside moves
to the same file in the include/uapi/linux/ directory.
If a new file appears then things get a bit more complicated as the
"headers +=" line has to move to include/uapi/linux/Kbuild. Only one new
