Added new config symbol `HARDEN_BRANCH_HISTORY` in order to harden Spectre style attacks against branch history and fixed rejects in following patches: * generic/hack-4.14/220-gc_sections.patch * generic/backport-4.14/306-v4.16-netfilter-remove-saveroute-indirection-in-struct-nf_.patch Other patches refreshed automagically. Run tested on ipq40xx/glinet-b1300 and mvebu/turris-omnia. Signed-off-by: Petr Štetiar <ynezz@true.cz>
