search for: vmcoreinfo

vmcoreinfo file could exists under /sys/kernel (valid on baremetal only) and/or under /sys/hypervisor (valid when Xen dom0 is running). Read only one of them. It means that only one PT_NOTE will be always created. Remove extra code for second PT_NOTE creation. Signed-off-by: Daniel Kiper <daniel.kiper@ora...

This patch is for linux-2.6.18-xen. - get the machine address of the vmcoreinfo area of xen - expose the machine address and the size of the vmcoreinfo area via /sys/hypervisor/vmcoreinfo so that the kexec-tools looks them.

In most cases under xen environment, it is enough to analyze a cause of system crash. * extract vmcoreinfo from /proc/vmcore makedumpfile 1.2.0 supports to extract the vmcoreinfo data from /proc/vmcore and uses it for dump filtering.
