Merge tag 'lkdtm-v4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull lkdtm update from Kees Cook:
"Fix rebuild problem with LKDTM's rodata test"
[ This, and the usercopy branch, both came in before the merge window
closed, but ended up in my 'need to look more' queue and thus got
merged only after rc1 was out ]
* tag 'lkdtm-v4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
lkdtm: Fix targets for objcopy usage
lkdtm: fix false positive warning from -Wmaybe-uninitialized
