+# Apply a stable patch update to the Fedora tree. This takes care of
+# - Downloading the patch from kernel.org
+# - Uploading the source file
+# - Removing old patch files
+# - Updating the spec file stable version
+# - Adding a proper changelog entry

+# Based on steps from https://fedoraproject.org/wiki/Kernel/DayToDay#Stable_kernel_update
