Also include additional patch for linux-6.12.y

This issue was only recently detected but was not triggering a problem for
the used kernel configuration as the current one does not use
`CONFIG_IA64_UNCACHED_ALLOCATOR=y`.

+Subject: [PATCH 38/38] ia64: fix incomplete partial revert
+
+The partial revert in dae19098164a8deb9c67c186a24ef35819af48d3 was
+incomplete, making a build time check in mm/debug.c:
+```
+BUILD_BUG_ON(ARRAY_SIZE(pageflag_names) != __NR_PAGEFLAGS + 1);
+```
+...failing when `CONFIG_IA64_UNCACHED_ALLOCATOR=y` was used.
