Subject: Add Linux 5.1+ compat fix for deprecated get_ds call
Origin: https://bugs.debian.org/928754 https://bugs.debian.org/934677
Bug-Ubuntu: https://bugs.launchpad.net/bugs/1830042

 This adds a compat fix for the deprecated get_ds helper function. For
 Linux 5.1 onwards this was replaced with KERNEL_DS, see Linux commit
 commit 736706bee3298208343a76096370e4f6a5c55915
 ("get rid of legacy 'get_ds()' function")
 .
