Josh Poimboeuf 1cbdc6f368 objtool: Fix UNWIND_HINT_{SAVE,RESTORE} across basic blocks ... [ Upstream commit 10b4c4bce3 ] If SAVE and RESTORE unwind hints are in different basic blocks, and objtool sees the RESTORE before the SAVE, it errors out with: vmlinux.o: warning: objtool: vmw_port_hb_in+0x242: objtool isn't smart enough to handle this CFI save/restore combo In such a case, defer following the RESTORE block until the straight-line path gets followed later.
