[Crash-utility] crash and the "hugemem" kernel

[Kurtis D. Rader]

Should crash be able to read a RHEL 3 hugemem dump? I've got a x86 14 GiB
netdump vmcore taken under controlled conditions (e.g., system was booted
and a crash dump manually invoked) that the crash(1) command doesn't like:

    vmcore: initialization failed
