Pull MIPS fixes from Ralf Baechle:
"Another round of MIPS fixes:
- compressed boot: Ignore a generated .c file
- VDSO: Fix a register clobber list
- DECstation: Fix an int-handler.S CPU_DADDI_WORKAROUNDS regression
- Octeon: Fix recent cleanups that cleaned away a bit too much thus
breaking the arch side of the EDAC and USB drivers.
- uasm: Fix duplicate const in "const struct foo const bar[]" which
GCC 7.1 no longer accepts.
- Fix race on setting and getting cpu_online_mask
- Fix preemption issue. To do so cleanly introduce macro to get the
size of L3 cache line.
- Revert include cleanup that sometimes results in build error
- MicroMIPS uses bit 0 of the PC to indicate microMIPS mode. Make
sure this bit is set for kernel entry as well.
- Prevent configuring the kernel for both microMIPS and MT. There are
no such CPUs currently and thus the combination is unsupported and
results in build errors.
This has been sitting in linux-next for a few days and has survived
automated testing by Imagination's test farm. No known regressions
pending except a number of issues that crept up due to lots of people
switching to GCC 7.1"

The Intel Cherry Trail Whiskey Cove PMIC does not contain a builtin
battery charger, instead boards with this PMIC use an external TI
bq24292i charger IC, which is connected to a SMBUS controller built into
the PMIC.
This commit adds an i2c-bus driver for the PMIC's builtin SMBUS
controller. The probe function for this i2c-bus will also register an
i2c-client for the TI bq24292i charger after the i2c-bus has been
registered.
Note that several device-properties are set on the client-device to
tell the bq24190 power-supply driver to integrate the Whiskey Cove PMIC
and e.g. use the PMIC's BC1.2 detection (through extcon) to determine
the maximum input current.
