If pm_runtime_get_sync() fails we should call pm_runtime_put_noidle().
This is probably not a critical fix as we should only hit this when
things are broken elsewhere.

While whitelisting Micron M500DC drives, the tweaked blacklist entry
enabled queued TRIM from M500IT variants also. But these do not support
queued TRIM. And while using those SSDs with the latest kernel we have
seen errors and even the partition table getting corrupted.

Updated version of the ltc2990 driver which supports all measurement
modes (current, voltage, temperature) available in the chip.
If devicetree is used, the mode must be specified with the property
"lltc,meas-mode". The format and possible values of the property are
described in the binding.
If devicetree is not used, the mode of the chip will not be configured.
Unless the chip is configured by another source, only the internal
temperature and supply voltage will be measured.

Currently tegra20-cpufreq kernel module isn't getting autoloaded because
there is no device associated with the module, this is one of two patches
that resolves the module autoloading. This patch adds a module alias that
will associate the tegra20-cpufreq kernel module with the platform device,
other patch will instantiate the actual platform device. And now it makes
sense to wrap cpufreq driver into a platform driver for consistency.

When the host controller accepts only 32bit writes, the value of the
16bit TRANSFER_MODE register, that has the same 32bit address as the
16bit COMMAND register, needs to be saved and it will be written
in a 32bit write together with the command as this will trigger the
host to send the command on the SD interface.
When sending the tuning command, TRANSFER_MODE is written and then
sdhci_set_transfer_mode reads it back to clear AUTO_CMD12 bit and
write it again resulting in wrong value to be written because the
initial write value was saved in a shadow and the read-back returned
a wrong value, from the register.
Fix sdhci_iproc_readw to return the saved value of TRANSFER_MODE
when a saved value exist.
Same fix for read of BLOCK_SIZE and BLOCK_COUNT registers, that are
saved for a different reason, although a scenario that will cause the
mentioned problem on this registers is not probable.

Pull EFI fixes from Thomas Gleixner:
- Use explicitely sized type for the romimage pointer in the 32bit EFI
protocol struct so a 64bit kernel does not expand it to 64bit. Ditto

- Handle randomized tex offset correctly in the ARM64 EFI stub to avoid
unaligned data resulting in stack corruption and other hard to
diagnose wreckage.

The connector .atomic_check() handler can be called with a NULL crtc
pointer in the connector state when the connector gets disabled
explicitly (through performing a legacy mode set or setting the
connector's CRTC_ID property to 0). This causes a crash as the crtc
pointer is dereferenced without any check.
Fix it by returning from the .atomic_check() handler when then crtc
pointer is NULL, as there is no check to be performed when the connector
gets disabled.

Currently ip6gre and ip6erspan share single metadata mode device,
using 'collect_md_tun'. Thus, when doing:
ip link add dev ip6gre11 type ip6gretap external
ip link add dev ip6erspan12 type ip6erspan external
RTNETLINK answers: File exists
simply fails due to the 2nd tries to create the same collect_md_tun.
The patch fixes it by adding a separate collect md tunnel device
for the ip6erspan, 'collect_md_tun_erspan'. As a result, a couple
of places need to refactor/split up in order to distinguish ip6gre
and ip6erspan.
First, move the collect_md check at ip6gre_tunnel_{unlink,link} and
create separate function {ip6gre,ip6ersapn}_tunnel_{link_md,unlink_md}.
Then before link/unlink, make sure the link_md/unlink_md is called.
Finally, a separate ndo_uninit is created for ip6erspan. Tested it
using the samples/bpf/test_tunnel_bpf.sh.

Pull ARM SoC fixes from Olof Johansson:
"A handful of fixes. I've been queuing them up a bit too long so the
list is longer than it otherwise would have been spread out across a
few -rcs.
In general, it's a scattering of fixes across several platforms,
nothing truly serious enough to point out.
There's a slightly larger batch of them for the Davinci platforms due
to work to bring them back to life after some time, so there's a
handful of regressions, some of them going back very far, others more
recent.
There's also a few patches fixing DT on Renesas platforms since they
changed some bindings without remaining backwards compatible,
splitting up describing LVDS as a proper bridge instead of having it
as part of the display unit.
We could push for them to be backwards compatible with old device
trees, but it's likely to regress eventually if nobody's actually
using said compatibility"

arm64: tegra: Device tree fixes for v4.17
This contains a one-line update to the device tree of the Tegra186 P3310
processor module, fixing the polarity of the PHY interrupt. Originally,
this was queued to go into v4.18, but the PHY ID matching patch has now
found its way into v4.17-rc5, which means that the PHY driver will know
how to identify the PHY on this board and try to use the interrupt. This
will unfortunately cause networking to break on P3310, hence why I think
this should go into v4.17.

The Hyper-V APIC code is built when CONFIG_HYPERV is enabled but the actual
code in that file is guarded with CONFIG_X86_64. There is no point in doing
this. Neither is there a point in having the CONFIG_HYPERV guard in there
because the containing directory is not built when CONFIG_HYPERV=n.
Further for the hv_init_apic() function a stub is provided only for
CONFIG_HYPERV=n, which is pointless as the callsite is not compiled at
all. But for X86_32 the stub is missing and the build fails.
Clean that up:
- Compile hv_apic.c only when CONFIG_X86_64=y
- Make the stub for hv_init_apic() available when CONFG_X86_64=n

Commit 7771c6645700 ("signal/arm: Document conflicts with SI_USER and
SIGFPE") broke the siginfo structure for userspace triggered signals,
causing the strace testsuite to regress. Fix this by eliminating
the FPE_FIXME definition (which is at the root of the breakage) and
use FPE_FLTINV instead for the case where the hardware appears to be
reporting nonsense.
