[Crash-utility] Crash utility with RT patchset

[Ron HM]

Hi Abhishek,
I guess the address convention seems x8664 when looking at
0xffffffxxxxxxxx type sort of 64 bit virtual address.

------
crash: invalid kernel virtual address: fffffff791ff5a5f  type: "64-bit
KVADDR"
-----

For arm64 bit the addressing would more be sort of 0xCCAbxxxxxxx sorts. Due
to the convention of memory addressing start addresses.

As a first check confirm if your crash and vmlinuz file is x8664 type
# file vmlinux
# file crash
