Subject[PATCH] scripts/decodecode: Fixup trapping instruction marker
Date
From: Borislav Petkov <borislav.petkov@amd.com>

When dumping "Code: " sections from an oops, the trapping instruction %rip
points to can be a string copy

2b:* f3 a5 rep movsl %ds:(%rsi),%es:(%rdi)

and the line contain a bunch of ":". Current "cut" selects only the
and the second field output looks funnily overlaid this:

2b:* f3 a5 rep movsl %ds <-- trapping instruction:(%rsi),%es:(%rdi

Fix this by selecting the remaining fields too.
