[PATCH v2 0/3] kexec support for Linux/m68k (tools part)

kexec support for Linux/m68k (tools part)

This is a set of patches to add kexec support for m68k to kexec-tools.

  - Kexec only, no kdump support yet (do you have enough RAM to keep a
    crashdump kernel in memory at all times? ;-)

Patches:
  - [PATCH 1/3] kexec: Let slurp_file_len() return the number of bytes
      - v2: no changes
  - [PATCH 2/3] kexec: Extract slurp_fd()
      - v2: new patch
  - [PATCH 3/3] kexec: Add m68k support
      - v2:
	  - Fix handling of virtual and physical addresses, for machines where
	    memory doesn't start at zero,
	  - Print a warning if the kernel size exceeds 4 MiB, as current kernels
	    cannot handle that,
	  - Check struct bootversion at the start of the kernel, and print a
	    warning if it cannot be found or doesn't match,
	  - Replace literal 4096 by PAGE_SIZE,
	  - Handle removal of page zero at the ELF program segment level, as
	    m68kboot does,
	  - Remove -PAGE_SIZE for the ramdisk location now the bug in
            locate_hole() is fixed,
	  - Use endian-correct types for bootinfo,
	  - Remove unused -? option handling, cfr. commit
	    bf9d0f055c791a26b2237b5a12b48ae1b7e0d550 ("kexec: Remove unused -?
	    option handling"),
	  - Use <asm/bootinfo.h> instead of our own definitions.

Notes:
  - Based on git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git

  - Tagged bootinfo is read from /proc/bootinfo by default, but this can be
    overridden using --bootinfo. No bootinfo editor is provided.
    The kexec command will replace/delete command line and ramdisk tags in the
    bootinfo.

Have fun!
