[PATCH] kdump: export per cpu crash notes pointer through sysfs
- Kexec on panic functionality allocates memory for saving cpu registers in
case of system crash event. Address of this allocated memory needs to be
exported to user space, which is used by kexec-tools.
- Previously, a single /sys/kernel/crash_notes entry was being exported as
memory allocated was a single continuous array. Now memory allocation being
dyanmic and per cpu based, address of per cpu buffer is exported through
"/sys/devices/system/cpu/cpuX/crash_notes"
