When building with C=2 and/or W=1, legitimate warnings are issued about
missing prototypes:
CHECK drivers/ras/debugfs.c
drivers/ras/debugfs.c:4:15: warning: symbol 'ras_debugfs_dir' was not declared. Should it be static?
drivers/ras/debugfs.c:8:5: warning: symbol 'ras_userspace_consumers' was not declared. Should it be static?
drivers/ras/debugfs.c:38:12: warning: symbol 'ras_add_daemon_trace' was not declared. Should it be static?
drivers/ras/debugfs.c:54:13: warning: symbol 'ras_debugfs_init' was not declared. Should it be static?
CC drivers/ras/debugfs.o
drivers/ras/debugfs.c:8:5: warning: no previous prototype for 'ras_userspace_consumers' [-Wmissing-prototypes]

Provide the proper includes.
[ bp: Take care of the same warnings for cec.c too. ]

Introduce a simple data structure for collecting correctable errors
along with accessors. More detailed description in the code itself.
The error decoding is done with the decoding chain now and
mce_first_notifier() gets to see the error first and the CEC decides
whether to log it and then the rest of the chain doesn't hear about it -
basically the main reason for the CE collector - or to continue running
the notifiers.
When the CEC hits the action threshold, it will try to soft-offine the
page containing the ECC and then the whole decoding chain gets to see
the error.

Implement a new debugfs interface for RAS susbsystem.
A file named daemon_active is added there accordingly.
This file is used to track if user space daemon accesses
perf/trace interface or not. One can track which daemon
opens it via "lsof /path/to/debugfs/ras/daemon_active".
