There can be many different subsystems register on the mce handler chain. Add a new bitmask field and define values so that handlers can indicate whether they took any action to log or otherwise handle an error. The default handler at the end of the chain can use this information to decide whether to print to the console log. Boris suggested a generic name and leaving plenty of spare bits for possible future use. [ bp: Move flag bits to the internal mce.h header and use BIT_ULL(). ] Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Borislav Petkov <bp@suse.de> Tested-by: Tony Luck <tony.luck@intel.com> Link: https://lkml.kernel.org/r/20200214222720.13168-4-tony.luck@intel.com
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.
