Pull ARM fixes from Russell King:
"The largest thing in this set of changes is bringing back some of the
ARMv3 code to fix a compile problem noticed on RiscPC, which we still
support, even though we only support ARMv4 there.(The reason is that the system bus doesn't support ARMv4 half-word
accesses, so we need the ARMv3 library code for this platform.)The rest are all quite minor fixes."

Commit 5a783cbc4836 ("ARM: 7478/1: errata: extend workaround for erratum
#720789") added workarounds for erratum #720789 to the range TLB
invalidation functions with the observation that the erratum only
affects SMP platforms. However, when running an SMP_ON_UP kernel on a
uniprocessor platform we must take care to preserve the ASID as the
workaround is not required.This patch ensures that we don't set the ASID to 0 when flushing the TLB
on such a system, preserving the original behaviour with the workaround
disabled.Cc:

Page migration encodes the pfn in the offset field of a swp_entry_t.
For LPAE, we support physical addresses of up to 36 bits (due to
sparsemem limitations with the size of page flags), requiring 24 bits
to represent a pfn. A further 3 bits are used to encode a swp_entry into
a pte, leaving 5 bits for the type field. Furthermore, the core code
defines MAX_SWAPFILES_SHIFT as 5, so the additional type bit does not
get used.This patch reduces the width of the type field to 5 bits, allowing us
to create up to 31 swapfiles of 64GB each.Cc:

Swap entries are encoding in ptes such that !pte_present(pte) and
pte_file(pte). The remaining bits of the descriptor are used to identify
the swapfile and offset within it to the swap entry.When writing such a pte for a user virtual address, set_pte_at
unconditionally sets the nG bit, which (in the case of LPAE) will
corrupt the swapfile offset and lead to a BUG:[ 140.494067] swap_free: Unused swap offset entry 000763b4

Many clocks that are used to provide sched_clock will reset during
suspend. If read_sched_clock returns 0 after suspend, sched_clock will
appear to jump forward. This patch resets cd.epoch_cyc to the current
value of read_sched_clock during resume, which causes sched_clock() just
after suspend to return the same value as sched_clock() just before
suspend.In addition, during the window where epoch_ns has been updated before
suspend, but epoch_cyc has not been updated after suspend, it is unknown
whether the clock has reset or not, and sched_clock() could return a
bogus value. Add a suspended flag, and return the pre-suspend epoch_ns
value during this period.The new behavior is triggered by calling setup_sched_clock_needs_suspend
instead of setup_sched_clock.Signed-off-by: Colin Cross

The EETI touchscreen asserts its IRQ line as soon as it has data in its
internal buffers. The line is automatically deasserted once all data has
been read via I2C. Hence, the driver has to monitor the GPIO line and
cannot simply rely on the interrupt handler reception.In the current implementation of the driver, irq_to_gpio() is used to
determine the GPIO number from the i2c_client's IRQ value.As irq_to_gpio() is not available on all platforms, this patch changes
this and makes the driver ignore the passed in IRQ. Instead, a GPIO is
added to the platform_data struct and gpio_to_irq is used to derive the
IRQ from that GPIO. If this fails, bail out. The driver is only able to
work in environments where the touchscreen GPIO can be mapped to an
IRQ.Without this patch, building raumfeld_defconfig results in:

Commit 3d55c29 "ARM: tegra: harmony: add regulator supply name and its
input supply" was supposed to fix all the problems with regulators on
Harmony. However, it appears that I only tested it when booting using
board files, not when booting using device tree. This change fixes two
problems with regulators when booting using device tree:1) That patch only created the vdd_sys regulator when booting using a
board file. Since this is the root of the whole regulator tree, this
caused no regulators to successfully initialize when booting using
device tree. The registration of vdd_sys is moved to fix this.2) When booting use DT, the regulator core sets has_full_constraints,
which in turn causes the core to turn off any regulators not marked
as always on. Some of the affected regulators are required for basic
system operation. To solve this, add always on constraints to all
relevant regulators. This doesn't affect booting using a board file
since nothing sets has_full_constraints in that case.Signed-off-by: Stephen Warren
