Set a failsafe of 35% that will keep all mainboard components
cool enough to prevent a thermal initiated emergency shutdown.
This value will also be used when the BMC is restarting or when the
phosphor-pid-control has been stopped.

| H A D | afs.h | dab17c1a Thu Nov 02 10:27:52 CDT 2017 David Howells <dhowells@redhat.com> afs: Fix directory read/modify race
Because parsing of the directory wasn't being done under any sort of lock,
the pages holding the directory content can get invalidated whilst the
parsing is ongoing.
Further, the directory page check function gets called outside of the page
lock, so if the page gets cleared or updated, this may return reports of
bad magic numbers in the directory page.
Also, the directory may change size whilst checking and parsing are
ongoing, so more care needs to be taken here.
Fix this by:
(1) Perform the page check from the page filling function before we set
PageUptodate and drop the page lock.
(2) Check for the file having shrunk and the page having been abandoned
before checking the page contents.
(3) Lock the page whilst parsing it for the directory iterator.
Whilst we're at it, add a tracepoint to report check failure.
