Ard BiesheuvelandGreg Kroah-Hartman a89888648e ARM: 9197/1: spectre-bhb: fix loop8 sequence for Thumb2 ...

[ Upstream commit 3cfb301997 ]

In Thumb2, 'b . + 4' produces a branch instruction that uses a narrow
encoding, and so it does not jump to the following instruction as
expected. So use W(b) instead.
