Once we get a glibc with 64-bit time_t, the LPSETTIMEOUT ioctl stops
working, since the command number and data structure no longer match.
To work around that, this introduces a new command number LPSETTIMEOUT_NEW
that is used whenever the modified user space evaluates the LPSETTIMEOUT
macro.
The trick we use is a bit convoluted but necessary: we cannot check for
any macros set by the C library in linux/lp.h, because this particular
header can be included before including sys/time.h. However, we can assume
that by the time that LPSETTIMEOUT is seen in the code, the definition
for 'timeval' and 'time_t' has been seen as well, so we can use the
sizeof() operator to determine whether we should use the old or the
new definition. We use the old one not only for traditional 32-bit user
space with 32-bit time_t, but also for all 64-bit architectures and x32,
which always use a 64-bit time_t, the new definition will be used only for
32-bit user space with 64-bit time_t, which also requires a newer kernel.
The compat_ioctl() handler now implements both commands, but has to
use a special case for existing x32 binaries. The native ioctl handler
now implements both command numbers on both 32-bit and 64-bit, though
the latter version use the same interpretation for both.
This is based on an earlier patch from Bamvor.

This flag determines whether the thread should currently
process the work in the thread->todo worklist.
The prime usecase for this is improving the performance
of synchronous transactions: all synchronous transactions
post a BR_TRANSACTION_COMPLETE to the calling thread,
but there's no reason to return that command to userspace
right away - userspace anyway needs to wait for the reply.
Likewise, a synchronous transaction that contains a binder
object can cause a BC_ACQUIRE/BC_INCREFS to be returned to
userspace; since the caller must anyway hold a strong/weak
ref for the duration of the call, postponing these commands
until the reply comes in is not a problem.
Note that this flag is not used to determine whether a
thread can handle process work; a thread should never pick
up process work when thread work is still pending.

When DT overlays are applied, each FPGA region keeps track of the fpga
image info as region->info. This pointer is assigned only if an
overlay causes the FPGA to be programmed. As it stands, this pointer
can be overwritten, causing a slow warning later when overlays are
removed.
This patch fixes this by changing the allowed behaviour. If a region
has received an overlay that programmed the FPGA, reject other
overlays that try to program the FPGA. To reprogram the FPGA, first
remove the overlay. This makes sense as removing the overlay also
removes the devices cleanly. Note that overlays that make DT changes
without reprogramming the FPGA are exempt from this restriction.

fpga-mgr has three methods for programming FPGAs, depending on
whether the image is in a scatter gather list, a contiguous
buffer, or a firmware file. This makes it difficult to write
upper layers as the caller has to assume whether the FPGA image
is in a sg table, as a single buffer, or a firmware file.
This commit moves these parameters to struct fpga_image_info
and adds a single function for programming fpgas.
New functions:
* fpga_mgr_load - given fpga manager and struct fpga_image_info,
program the fpga.
* fpga_image_info_alloc - alloc a struct fpga_image_info.
* fpga_image_info_free - free a struct fpga_image_info.
These three functions are unexported:
* fpga_mgr_buf_load_sg
* fpga_mgr_buf_load
* fpga_mgr_firmware_load
Also use devm_kstrdup to copy firmware_name so we aren't making
assumptions about where it comes from when allocing/freeing the
struct fpga_image_info.
API documentation has been updated and a new document for
FPGA region has been added.

* GICv4 Support for KVM/ARM
All ARM patches were in next-20171113. I have postponed most x86 fixes
to 4.15-rc2 and UMIP to 4.16, but there are fixes that would be good to
have already in 4.15-rc1:
* re-introduce support for CPUs without virtual NMI (cc stable)
and allow testing of KVM without virtual NMI on available CPUs
* fix long-standing performance issues with assigned devices on AMD
(cc stable)

...
A small batch of fixes, about 50% tagged for stable and the rest for recently
merged code.
There's one more fix for the >128T handling on hash. Once a process had
requested a single mmap above 128T we would then always search above 128T. The
correct behaviour is to consider the hint address in isolation for each mmap
request.
Then a couple of fixes for the IMC PMU, a missing EXPORT_SYMBOL in VAS, a fix
for STRICT_KERNEL_RWX on 32-bit, and a fix to correctly identify P9 DD2.1 but in
code that is currently not used by default.

Pull SCSI target updates from Nicholas Bellinger:
"This series is predominantly bug-fixes, with a few small improvements
that have been outstanding over the last release cycle.
As usual, the associated bug-fixes have CC' tags for stable.
Also, things have been particularly quiet wrt new developments the
last months, with most folks continuing to focus on stability atop 4.x
stable kernels for their respective production configurations.
Also at this point, the stable trees have been synced up with
mainline. This will continue to be a priority, as production users
tend to run exclusively atop stable kernels, a few releases behind
mainline.
The highlights include:
- Fix PR PREEMPT_AND_ABORT null pointer dereference regression in
v4.11+ (tangwenji)
- Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu)
- Add netlink command reply supported option for each device (Kenjiro
Nakayama)
- cxgbit: Abort the TCP connection in case of data out timeout (Varun
Prakash)
- Fix PR/ALUA file path truncation (David Disseldorp)
- Fix double se_cmd completion during ->cmd_time_out (Mike Christie)
- Fix QUEUE_FULL + SCSI task attribute handling in 4.1+ (Bryant Ly +
nab)
- Fix quiese during transport_write_pending_qf endless loop (nab)
- Avoid early CMD_T_PRE_EXECUTE failures during ABORT_TASK in 3.14+
