s390/crashdump: move fill_cpu_elf_notes() prototype to header file

2012-09-26T13:45:22Z

Move fill_cpu_elf_notes() prototype to header file. This way we get compile errors if e.g. the number of function parameters get changed. Otherwise it's possible to change just the definition and everything else still compiles fine, but the result is broken code. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

[S390] kernel: Add OS info memory interface

2012-03-11T15:59:29Z

In order to allow kdump based stand-alone dump, some information has to be passed from the old kernel to the new dump kernel. This is done via a the struct "os_info" that contains the following fields: * crashkernel base and size * reipl block * vmcoreinfo * init function A pointer to os_info is stored at a well known storage location and the whole structure as well as all fields are secured with checksums.

[S390] Remove error checking from copy_oldmem_page()

2011-10-30T14:16:47Z

Currently it can happen that the pre-allocated ELF header contains a wrong memory map which would result in errors when copying /proc/vmcore. In order to still get a valid vmcore, we (temporarily) disable the error checking in copy_oldmem_page(). This will then produce zero pages for those memory regions.
