+- Remove downstream tboot-disa-ibt.patch workaround .(RHEL-149438)
+  Previous builds appended "ibt=off" to GRUB_CMDLINE_LINUX_TBOOT to avoid
+  shutdown crashes on CET-enabled systems. With RHEL-10 kernels enabling
+  CET/IBT, the tboot > firmware shutdown path triggered #CP faults because
+  firmware shutdown_entry code lacks ENDBR instructions and is not CET-safe.
+  The global disable was a temporary mitigation.
+  Upstream discussion continues to debate a final fix, but the solution
+  posted in https://sourceforge.net/p/tboot/mailman/message/59247821/
+  surgically disables CET only around the tboot shutdown_entry call,
+  preventing the crash without disabling IBT system-wide.
+  RHEL commit 358ed91e4c8a2eb2ab0df50d0e6b71b01dc7e1ed incorporates this fix
+  in kernel kernel-6.12.0-205.el10, so the downstream workaround is no longer
+  required.
+  Update gating.yaml: remove infeasible automated test requirement
+  (tboot requires physical TPM and manual GRUB interaction)
+  Resolves: RHEL-149438
