Robert Richter. Debug options like DEBUG_TEST_DRIVER_REMOVE, KASAN and DEBUG_KMEMLEAK unearthed issues with the lifespan of memory allocated by the EDAC memory controller descriptor due to misdesigned memory freeing, done partially by the EDAC core *and* the driver core, which is problematic to say the least. These two are minimal fixes to take care of stable - a proper rework is following which cleans up that mess properly. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAl5I+WEACgkQEsHwGGHe VUpcwA//aF6HO2nN+fMsfauVjTEdaElGKqTSzrByVjXjah5mDKH6RZlDandyhIe2 /Q2GYk/10ASin+FkDsc2mZ5nBcOS6rTS1avOvhlvc9xUYkzuXfvx2fZas9+81B4h 7xRrdXzU9S4ubHAkAt9oTXn2qoeq1THfJtudMh9imgmtA+qKSSTihCP4gVwuh65H w91qxEIkxB5hBTxBtOI/vueTvBvvNfqyJ/nDh8uNRFAbPe//HwTwnrFhJmNBhyWD S6vdYrV1UnBGZpPvS46jROmsrJgsKhGH4i7zkhS2a83CvXcyIvcPFbUHXUFCkHB6 NXeFZUIl70x5MeIElucd8g4z5vY14gY3s1mGJ/M1ErdiqQ96aGmlmh9DpArKvVqL HhwAHmnhbgjR5cvdYiyyC+30ZDd6Xm/aZWYj4Ks8cMOSLGvFYSUaAfnYBaTBMhWF S4JJBT0NBUTZhGMqr0Zyv0uOsqf+IB+63sNYI9sMR4m72noULTF2tN2tZZgkXmv8 QxdxwHzJ9V12ZEMhleyUx9eDPPrs5jWRoP2Io1Ws3DA1P82HqVfhsDbz1DObX2Mo VLkXG462ANmC2hIdSr7P0uByWtRK8Nd+OMJeltK5SX2MMShQo6xO3QOkJNc7bd7X 9YZ0R9eqUlSjJcyTZZt4DUVRIzOaVOEjRZKy6wN+zNmSmo8Nock= =UTcs -----END PGP SIGNATURE----- Merge tag 'edac_urgent_for_5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras Pull EDAC fixes from Borislav Petkov: "Two fixes for use-after-free and memory leaking in the EDAC core, by Robert Richter.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
