[Crash-utility] HEADS-UP: [PATCH v2 0/4] Compressed KDUMP core analysis support for PPC32 breaks PPC64 compressed kdump support

[Dave Anderson]

Unfortunately crash-6.0.3 does not work with ppc64 compressed kdumps
because of the recently-added support for the 32-bit ppc architecture:

    - Implemented support for the analysis of 32-bit PPC compressed kdump
      vmcores.
      (suzuki at in.ibm.com)

It fails like so:

  # crash vmlinux vmcore

  crash 6.0.3

  WARNING: machine type mismatch:
           crash utility: PPC64
           vmcore: PPC

  crash: vmcore: not a supported file format

  Usage:

It does not affect ELF core dumps.

I'll release crash-6.0.4 a bit sooner that I expected.  Sorry for any
inconvenience this may have caused.
