I2C: runtime: Fix checks which make legacy suspend to never get called
For devices which are not adapted to runtime PM a call to
pm_runtime_suspended always returns true.
Hence the pm_runtime_suspended checks below prevent legacy
suspend from getting called.
So do a pm_runtime_suspended check only for devices with a
dev_pm_ops populated (which hence do not rely on the legacy
suspend)

i2c: Fix for suspend/resume issue
In current i2c core driver, call to pm_runtime_set_active from
i2c_device_pm_resume will unconditionally enable i2c module and
increment child count of the parent. Because of this, in CPU Idle
path, i2c does not idle, preventing Core to enter retention. Also i2c
module will not be suspended upon system suspend as
pm_runtime_set_suspended is not called from i2c_device_pm_suspend.
This issue is fixed by removing pm_runtime_set_active call from resume
path which is not necessary.

driver core: platform_bus: allow runtime override of dev_pm_ops
Currently, the platform_bus allows customization of several of the
busses dev_pm_ops methods by using weak symbols so that platform code
can override them. The weak-symbol approach is not scalable when
wanting to support multiple platforms in a single kernel binary.
Instead, provide __init methods for platform code to customize the
dev_pm_ops methods at runtime.
NOTE: after these dynamic methods are merged, the weak symbols should
be removed from drivers/base/platform.c. AFAIK, this will only
affect SH and sh-mobile which should be converted to use this
runtime approach instead of the weak symbols. After SH &
sh-mobile are converted, the weak symobols could be removed.

hwmon (coretemp): Fix build breakage if SMP is undefined
Commit
e40cc4bdfd4b89813f072f72bd9c7055814d3f0f introduced
a build breakage if CONFIG_SMP is undefined. This commit
fixes the problem.
This fix is only a workaround. For a real fix, cpu_sibling_mask() should
be defined in UP include code, eg in linux/smp.h, and asm/smp.h should not be
included directly. This fix is currently not possible because asm/smp.h defines
cpu_sibling_mask() unconditionally and is included directly from many source
files.

tcp_sendmsg() truncates iov_len to an 'int' which a 4GB write to write

There is also the problem higher up of how verify_iovec() works. It
wants to prevent the total length from looking like an error return

However it does this using 'int', but syscalls return 'long' (and
