The following series implements multiple pmsg. This feature allows
userspace program to control individual content aging or priority.
If a pstore backend module(e.g. ramoops) requires the multiple pmsg
instances when registering itself to pstore, multiple /dev/pmsg[ID]
are created. Writes to each /dev/pmsg[ID] are isolated each other. After
reboot, the contents are available in /sys/fs/pstore/pmsg-[backend]-[ID].
In addition, we add multiple pmsg support for ramoops. We can
specify multiple pmsg area size by its module parameter as follows.
pmsg_size=0x1000,0x2000,...
