If I had a dollar for every time this would have helped *this morning*,
I'd at least be buying you enough coffee for it to be problematic.

I'd be keen in it heading to stable@ fixing the actual problem of
"people can't actually include the damn kernel version in their bug
report" - but maybe somebody else can work out if this is something
that's likely to be accepted.

[PATCH v2] powerpc: Append linux_banner to exception information in xmon.

[Rashmica Gupta]

Currently if you are in xmon without an oops etc. to view the kernel
version you have to type "d $linux_banner" - not necessarily obvious. As
this is useful information, append to the output of "e" command.

Example output:
$mon> e
