Hi, This set of patches contains initial kexec/kdump implementation for Xen v2 (previous version were posted to few people by mistake; sorry for that). Currently only dom0 is supported, however, almost all infrustructure required for domU support is ready. Jan Beulich suggested to merge Xen x86 assembler code with baremetal x86 code. This could simplify and reduce a bit size of kernel code.

For RMRRs covering a single page that actually resulted in the immediately preceding page to get checked (which could have resulted in a false warning)....

Sending things in a smaller chunks since it makes their reviewing easier. This part part 2/3 of the secboot refactoring/PMU command support patch series. Part 1 was the new falcon library which should be merged soon now. This series is mainly a refactoring/sanitization of the existing secure boot code. It does not add new features (part 3 will). Secure boot handling is now separated by NVIDIA
