# HG changeset patch
# User kaf24@xxxxxxxxxxxxxxxxxxxx
# Node ID b54e981957ebd69c9b413df668d3a49908d13f23
# Parent 8d0b62f0aa8d5a3dcb51f98403511d21601a0752
Various fixes to Xen stack management. Ensure the cpu0_stack
is always sufficiently aligned (requires some linker script
tricks). Small fixes to show_trace() and ensure that Xen
stack pointers are always below the 'struct cpu_info' region.
