x86/dumpstack: Don't mention RIP in "Code: "
Commit
238c91115cd0 ("x86/dumpstack: Fix misleading instruction pointer error message")
changed the "Code:" line in bug reports when RIP is an invalid pointer.
In particular, the report currently says (for example):
BUG: kernel NULL pointer dereference, address: 0000000000000000
...
RIP: 0010:0x0
Code: Unable to access opcode bytes at RIP 0xffffffffffffffd6.
That
Unable to access opcode bytes at RIP 0xffffffffffffffd6.
is quite confusing as RIP value is 0, not -42. That -42 comes from
"regs->ip - PROLOGUE_SIZE", because Code is dumped with some prologue
(and epilogue).
So do not mention "RIP" on this line in this context.
