platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

The special checks for whether we have a base IRQ offset or not
is surplus if we use the simple IRQ domain. The IRQ offset
zero will be interpreted as a linear domain case.

Plus this makes sure we allocate descriptors where need be, or
warn if they are preallocated with SPARSE_IRQ.

The code in the em driver seems to want to try to do the job of
the linear IRQ domain (allocate descriptors and grab a virtual
range). So why not just use the linear IRQ domain? The code is
now cut down so we don't need isolated functions for this.

Also note that we use irq_create_mapping() to make sure
descriptors are allocated for these IRQs.

Also fixed the FIXME to remove the domain after use.

The MVEBU driver probably just wants a few IRQs. Using the simple
domain has the upside of allocating IRQ descriptors if need be,
especially in a SPARSE_IRQ environment.

The Tegra driver tries to do the work of irq_domain_add_linear()
by reserving a bunch of descriptors somewhere and keeping track
of the base offset, then calling irq_domain_add_legacy(). Let's
stop doing that and simply use the linear IRQ domain.

For this to work: use irq_create_mapping() in the IRQ iterator
so that the descriptors get allocated here.

The gpio_export function uses nested if statements and the status
variable to handle the failure cases. This makes the function logic
difficult to follow. Refactor the code to abort immediately on failure
using goto. This makes the code slightly longer, but significantly

The hostprogs need access to the CONFIG_* symbols found in
include/generated/autoconf.h.  But commit abbf1590 ("UAPI: Partition
the header include path sets and add uapi/ header directories") replaced
$(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary
include paths.

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 top-level Makefile it's actually empty in arch/x86/boot/Makefile.

Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells:
 "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
     file has appeared since the 9th and I judge this type of event relatively
     unlikely.
