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!
