Subject[PATCH v6 0/6] reorganize and add FADump sysfs files
Currently, FADump sysfs files are present inside /sys/kernel directory.
But as the number of FADump sysfs file increases it is not a good idea to
push all of them in /sys/kernel directory. It is better to have separate
directory to keep all the FADump sysfs files.

Patch series reorganizes the FADump sysfs files and avail all the existing
FADump sysfs files present inside /sys/kernel into a new directory
/sys/kernel/fadump. The backward compatibility is maintained by adding a
symlink for every sysfs file that has moved to new location. Also a new
FADump sys interface is added to get the amount of memory reserved by FADump
for saving the crash dump.

v1 -> v5:

v5 -> v6
- Unregister FADump if fadump group creation fails.
- Remove fadump_enabled symlink if fadump_registered symlink
creation fails.
- Removed CREATE_SYMLINK macro.

the symlink name
