* docs: ras: get rid of some warningsMauro Carvalho Chehab2020-04-201-7/+9
| | | | | | | | | | | | | | | | | Sphinx produce some warnings due to a bad table format: Documentation/admin-guide/ras.rst:358: WARNING: Definition list ends without a blank line; unexpected unindent.

Documentation/admin-guide/ras.rst:363: WARNING: Definition list ends without a blank line; unexpected unindent. Rearrange the things there in order to supress the warnings while being precise at the Sphinx output about how ranks are mapped into csrows.

* Docs: fix table problems in ras.rstJonathan Corbet2017-06-231-5/+5
| | | | | | | | | | | | | | Two table problems caused the PDF build to fail: - Evidently multirow cells are not appreciated in table headers, so remove such from the "CS Rows" table. - The logging message structure table was incorrectly formatted, with two "+" instead of "|". The HTML build is forgiving of such things, but PDF is not. Acked-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

* scripts/spelling.txt: add "an user" pattern and fix typo instancesMasahiro Yamada2017-02-281-1/+1
| | | | | | | | | | | | | | | | | Fix typos and add the following to the scripts/spelling.txt: an user||a user an userspace||a userspace I also added "userspace" to the list since it is a common word in Linux. I found some instances for "an userfaultfd", but I did not add it to the list. I felt it is endless to find words that start with "user" such as "userland" etc., so must draw a line somewhere.

* EDAC: Expose per-DIMM error counts in sysfsAaron Miller2017-01-191-0/+20
| | | | | | | | | | | | | The old csrowX sysfs directories have per-csrow error counters, but the new dimmX directories do not currently expose error counts. EDAC already keeps these counts, add them to sysfs so per-DIMM counts are still available when CONFIG_EDAC_LEGACY_SYSFS=n.
