Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.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.

RHEL9.0 has been stabilized and finalized for GA (early May) at this point.
So this will be available in CentOS Stream and RHEL 9.1 (unless requested & approved for 9.0.z if critical).
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
For information on the advisory (Moderate: kernel security, bug fix, and enhancement update), and where to find the updated
files, follow the link below.

Description of problem: Kernel build fails if CONFIG_RHEL_DIFFERENCES is disabled. Version-Release number of selected component (if applicable): kernel-5.14.0-42.el9 How reproducible: Always Steps to Reproduce: 1. Change the CONFIG_RHEL_DIFFERENCES option from =y to 'not set' 2. Build the kernel 3. Actual results: Fails with errors ld: arch/x86/xen/pci-swiotlb-xen.o: in function `pci_hw_disabled': /home/yagi2/rpmbuild/kernel/55/BUILD/kernel-5.14.0-55.el9/linux-5.14.0-55.noRD.el9.x86_64/./include/linux/pci.h:1468: multiple definition of `pci_hw_disabled'; arch/x86/events/amd/ibs.o:/home/yagi2/rpmbuild/kernel/55/BUILD/kernel-5.14.0-55.el9/linux-5.14.0-55.noRD.el9.x86_64/./include/linux/pci.h:1468: first defined here (and many more lines) Expected results: Build succeeds. Additional info: pci_hw_disabled is defined twice, one in include/linux/pci.h and another in drivers/pci/pci-driver.c.
