orangefs: avoid time conversion function
The new orangefs code uses a helper function to read a time field to
its private structures from struct iattr. This will conflict with the
move to 64-bit timestamps in the kernel and is generally not necessary.
This replaces the conversion with a simple cast to time64_t that shows
what is going on. As the orangefs-internal representation already uses
64-bit timestamps, there should be no ambiguity to negative values,
and the cast ensures that we treat them as times before 1970 on both
32-bit and 64-bit architectures, rather than times after 2038. This
patch keeps that behavior.

If the module init code fails after calling ftrace_module_init() and before

ftrace_module_init() allocates pages to store the locations that ftrace
hooks are placed in the module text. If do_init_module() fails, it still
calls the MODULE_GOING notifiers which will tell ftrace to do a clean up of
the pages it allocated for the module. But if load_module() fails before
then, the pages allocated by ftrace_module_init() will never be freed.
Call ftrace_release_mod() on the module if load_module() fails before

Commit
69fb4dcada77 ("power: Add an axp20x-usb-power driver") introduced a
new driver for the USB power supply used on various Allwinner based SBCs.
However, the driver was not added to multi_v7_defconfig which breaks USB
support for some boards (e.g. LeMaker BananaPi) as the kernel will now
turn off the USB power supply during boot by default if the driver isn't
present. (This was not the case in linux 4.3 or lower where the USB power
was always left on.)
Hence, add the driver to multi_v7_defconfig in order to keep USB support
working on those boards that require it.

When mapping a non-page-aligned scatterlist entry, we copy the original
offset to the output DMA address before aligning it to hand off to
iommu_map_sg(), then later adding the IOVA page address portion to get
the final mapped address. However, when the IOVA page size is smaller
than the CPU page size, it is the offset within the IOVA page we want,
not that within the CPU page, which can easily be larger than an IOVA

Commit

"arm/versatile: Fix versatile irq specifications"
has an off-by-one error on the Versatile AB that has
been regressing the Versatile AB hardware for some time.
However it seems like the interrupt assignments have
never been correct and I have now adjusted them according
to the specification. The masks for the valid interrupts
made it impossible to assign the right SIC interrupt
for the MMCI, so I went in and fixed these to correspond
to the specifications, and added references if anyone
wants to double-check.
Due to the Versatile PB including the Versatile AB
as a base DTS file, we need to override and correct
some values to correspond to the actual changes in the
hardware.
For the Versatile PB I don't think the IRQ line
assignment for MMCI has ever been correct for either of
the two MMCI blocks. It would be nice if someone with the
physical PB board could test this.
Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.
