Symptoms:
	PHKL_30974:
	( SR:8606364219 CR:JAGaf24873 )
	Online diagnostics is seeing duplicated Corrected
	Platform Error logs.  It is seeing the same corrected
	error record more than once thus causing them to think
	there are more corrected errors than there really are.
	This might cause the user to unnecessarily think they
	must replace hardware.

	PHKL_30289:
	( SR:8606343412 CR:JAGaf04306 )
	The following message appears one or more times in
	the dmesg and syslog output and may cause confusion:

	MCA/CMC[0]:handler = OS_CPEV, sub_type = Generic
	MCA/CMC[0]:00 00 00 01 00 00 20 01 e0 00 00 00 00 24 d7 10
	MCA/CMC[0]:00 00 00 00 33 59 56 90 00 00 00 00 12 83 08 c0
	MCA/CMC[0]:3f df 6a c1 00 00 00 00 00 00 00 00 00 00 0e d0

	or

	MCA/CMC[0]:handler = OS_CMC, sub_type = Generic
	MCA/CMC[0]:00 00 00 01 00 00 20 01 e0 00 00 00 00 24 d7 10
	MCA/CMC[0]:00 00 00 00 33 59 56 90 00 00 00 00 12 83 08 c0

Defect Description:
	PHKL_30974:
	( SR:8606364219 CR:JAGaf24873 )
	On IPF Platforms, online diagnostics provides the user with
	information about errors that have been corrected by
	hardware or firmware.  The corrected errors are counted and
	the user is notififed that there might be a problem after a
	large number of the errors are observed.  A problem is being
	seen on non-cellular systems with multi-core processors.
	The online diagnostics is seeing a duplication of a single
	log causing the system to think there are more corrected
	error logs than really exist.  This could cause the online
	diagnostics to incorrectly notify the user that there a
	problem exists, and lead to the user replacing hardware when
	they don't need to.

	Resolution:
	The patch PHKL_30974 will cause the kernel not to produce
	duplicate error records for online diagnostics.

	PHKL_30289:
	( SR:8606343412 CR:JAGaf04306 )
	Hardware is able to correct certain types of memory
	errors automatically.  These "single bit" memory
	errors happen occasionally on any system.  Since
	they have been corrected there is no concern, unless
	it happens too frequently.

	The messages that are printed to the dmesg and syslog
	are not useful to the user, since they do not
	contain any pertinent information.  The online
	diagnostics system will notify the user if there
	is an actual problem.

	These messages can be misleading and may cause
	the user to think hardware might be defective even
	if it is not.  These messages are to be removed to
	avoid confusion.

	Resolution:
	The patch PHKL_30289 will cause the kernel not to print
	the confusing messages to the dmesg buffer.

Enhancement:
	No
