Documentation: power: Use kcalloc() instead of kzalloc()

2024-01-23T06:10:42+00:00

As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, in the example code use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function. At the same time, modify the translations accordingly.

docs: power: convert docs to ReST and rename to *.rst

2019-06-14T21:08:36+00:00

Convert the PM documents to ReST, in order to allow them to build with Sphinx. The conversion is actually: - add blank lines and indentation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
