Source: eglibc
Version: 2.13-27
Severity: important
Tags: patch
The following five patches will be attached to the report:
core-2011-08-31.diff
ports-2011-08-31.diff
ports-2011-09-17.diff
ports-2011-10-30.diff
ports-2012-03-31.diff
core-2011-08-31.diff replaces hppa/local-stack-grows-up.diff.
hppa/local-stack-grows-up.diff must be deleted first. The
core patch addresses stack grows up issues.
The ports patches must be applied in order of date. They address
a variety of issues (e.g., udev bootstrap failure due to incorrect
flags, various pthread condition failures).
The patches have been collected from messages posted to the parisc
linux mailing list, and from private work with Carlos O'Donell.
I have adjusted the original patches so that they apply to 2.13.
Aurelien, would you please apply these changes?
