Fix the cases of . when any of two multiplicands is
+0 or -0, and the third input is also +0 or -0. Depending on the signs
of inputs, certain special cases must be handled.
A relevant example:

If the last clkids defined have no hw pointer associated with them in

Several drivers call to_platform_device() to get platform_device
and pass it to platform_get_drvdata(). In platform_get_drvdata(),
the platform_device is converted back to struct device again.

On NUMA systems with dynamic processors, the content of the cpumask
may change over time. As new processors are added via DLPAR operations,
workqueues are created for them. Depending upon the order in which CPUs
are added/removed, we may run into problems with the content of the

Hi Miklos,
I made a first attempt to reproduce the failure but did not get lucky.

Does this inode correspond to foo, bar or a preexisting file?
Do you mind sharing the output of the following command?

The field perf_callchain, if available, is added to the sampling
events during the CTF conversion. It is an array of u64 values.
The perf_callchain_size field contains the size of the array.
It will allow the analysis of sampling data in trace visualization tools
like Trace Compass. Possible analy
This adds documentation on the environment variables needed to the
