[Xen-devel] [PATCH 2/7] elf: Increase buf size in get_pt_note_info()

[Daniel Kiper <daniel.kiper@xxxxxxxxxx>]

get_pt_note_info() always ignores VMCOREINFO_XEN note
because buf size is too small. It does not have place
for \0 char which marks EOS. This patch fixes that bug
and VMCOREINFO_XEN note living in /proc/vmcore file
could be properly detected now.
