[S390] kernel: Add OS info memory interface 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() 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.
