Sunrpc: Supports hexadecimal number for sysctl files of sunrpc debug

This patch let those files support accepting hexadecimal number,

thermal: rockchip: support the sleep pinctrl state to avoid glitches in s2r
When we come out of system suspend state (S3) the tsadc will have been
reset and back at its default state. While reprogramming the tsadc
it's possible that we'll glitch the output and unintentionally cause
the "over temperature" GPIO to be asserted. Since the over
temperature GPIO is often hooked up to something that will cause a
reboot or shutdown in hardware, this glitch can be catastrophic on
some boards.
We'll add support for selecting the "sleep" pinctrl state at suspend
time. Boards can use this to effectively disable the tsadc at suspend
time and avoid glitches when the system is resumed.

AFAIK, the TSADC controller is reset, the tshut polarity will be

Says:
The TSADC get the temperature on rockchip thermal.
If T(current temperature) < (setting temperature), the OTP output the

In some cases, the OTP pin is connected to the PMIC, maybe the

version of load reverse for two reasons:
- the sequence of load reversed, apply constant mask, save reversed can
be optimized to load, apply reversed mask, save
- builtins are slightly better to optimize e.g. gcc instruction
scheduler cannot optimize grouping on inline assemblies.
To enable set we have to ARCH_USE_BUILTIN_BSWAP.

Path verification is either done via dasd_eckd_read_conf() which is

do_path_verification_work() which is triggered after path events.
The dasd_eckd_read_conf() version added paths unconditionally and did

working although they had paths validated successfully. After a resume

All the interfaces removed were removed on suspend,
and drv_stop() was called. At this point the driver

* wowlan is configured, drv_resume() == 1
There is no definitive expected behavior in this case,
as each driver might have different expectations (e.g.
setting some flags on suspend/restart vs. not handling
spurious recovery).
For now, simply let the hw_restart work run again after
