* gcov: docs: add a note on GCC vs Clang differencesTri Vo2019-05-141-4/+14
| | | | | | | | | | | | | | | | | | | | | | Document some things of note to gcov users: 1. GCC gcov and Clang llvm-cov tools are not compatible. 2. The use of GCC vs Clang is transparent at build-time. Also adjust the documentation to account for the removal of config symbol CONFIG_GCOV_FORMAT_AUTODETECT by commit 6a61b70b43c9 ("gcov: remove CONFIG_GCOV_FORMAT_AUTODETECT").

* | kselftest: Add test module framework headerTobin C. Harding2019-04-081-2/+92
|/ | | | | | | | | | | | | | | | | | | | | | kselftest runs as a userspace process. Sometimes we need to test things from kernel space. One way of doing this is by creating a test module. Currently doing so requires developers to write a bunch of boiler plate in the module if kselftest is to be used to run the tests. This means we currently have a load of duplicate code to achieve these ends. If we have a uniform method for implementing test modules then we can reduce code duplication, ensure uniformity in the test framework, ease code maintenance, and reduce the work required to create tests. This all helps to encourage developers to write and run tests. Add a C header file that can be included in test modules. This provides a single point for common test functions/macros. Implement a few macros that make up the start of the test framework. Add documentation for new kselftest header to kselftest documentation.

* | mm: kmemleak: treat vm_struct as alternative reference to vmalloc'ed objectsCatalin Marinas2017-07-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kmemleak requires that vmalloc'ed objects have a minimum reference count of 2: one in the corresponding vm_struct object and the other owned by the vmalloc() caller. There are cases, however, where the original vmalloc() returned pointer is lost and, instead, a pointer to vm_struct is stored (see free_thread_stack()). Kmemleak currently reports such objects as leaks. This patch adds support for treating any surplus references to an object as additional references to a specified object. It introduces the kmemleak_vmalloc() API function which takes a vm_struct pointer and sets its surplus reference passing to the actual vmalloc() returned pointer. The __vmalloc_node_range() calling site has been modified accordingly.

* mm: kmemleak: avoid using __va() on addresses that don't have a lowmem mappingCatalin Marinas2016-10-111-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Some of the kmemleak_*() callbacks in memblock, bootmem, CMA convert a physical address to a virtual one using __va(). However, such physical addresses may sometimes be located in highmem and using __va() is incorrect, leading to inconsistent object tracking in kmemleak. The following functions have been added to the kmemleak API and they take a physical address as the object pointer. They only perform the corresponding action if the address has a lowmem mapping: kmemleak_alloc_phys kmemleak_free_part_phys kmemleak_not_leak_phys kmemleak_ignore_phys The affected calling places have been updated to use the new kmemleak API.
