the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

RHEL 6 will be branched from a mainline kernel, so there should be no syncing required.
The feature requested has already been accepted into the upstream code base
planned for the next major release of Red Hat Enterprise Linux.
When the next milestone release of Red Hat Enterprise Linux 6 is available,
please verify that the feature requested is present and functioning as
desired.
Am I correct in thinking that if we take this driver update it will also satisfy the feature requests in:
Bug 462959 - [LTC 6.0 FEAT] 201667:eHEA support for 16GB memory page
Bug 462954 - [LTC 6.0 FEAT] 201587:Enable eHEA with kdump support
It is true that this driver update will satisfy the following as well.
Bug 462959 - [LTC 6.0 FEAT] 201667:eHEA support for 16GB memory page
Bug 462954 - [LTC 6.0 FEAT] 201587:Enable eHEA with kdump support
In fact, as things moving right now, we confirm that all of the HEA driver features are in the kernel 2.6.29 already. There is no need for any codedrops if RHEL6 takes kernel 2.6.29 or later. Therefore, all of the HEA feature requests are cancelled, including this one.
Thanks.
