-
-The commit 4e76ec7 "libfdt: Add fdt_next_subnode() to permit easy
-subnode iteration" adds new functions (fdt_{first,next}_subnode) but

+Fix a test that has an expiration date of 2016-09-17:

+
+The patch has been altered by commenting out a diff that does not apply
+to the version of GnuPG that we are applying it to, 2.1.13. This is
+what the patch author refers to below with "This commit includes changes
+to the old test as well, for those who need to backport it." We keep the
+old test and comment out the new test.

+
+* tests/openpgp/gpg-agent.conf.tmpl: Drop trailing newlines.
+* tests/openpgp/tofu.scm: Fake system time.
+* tests/openpgp/tofu.test: Likewise.

+This patch to LLVM is required by the developers of the Extempore language.
+The following explanation was posted to the extemporelang@googlegroups.com
+mailing list:
+
+"There is an assumption in the parser that all definitions occur within the
+same compilation unit - i.e. the parser has local state about what has been
+parsed in this unit of work.  Extempore obviously does lots of little units
+rather than one big unit and this causes problems for named types that were
+defined in another unit - which they always are.  The patch simply checks the
+current module to see if the type has been previously defined, and intervenes
+appropriately if it has."

+The 'c_rehash' program is seldom used, but it is used nonetheless
