    Subject[PATCH 6.0 439/862] ia64: export memory_add_physaddr_to_nid to fix cxl build error
    Date
    From: Randy Dunlap <rdunlap@infradead.org>

    [ Upstream commit 97c318bfbe84efded246e80428054f300042f110 ]

    cxl_pmem.ko uses memory_add_physaddr_to_nid() but ia64 does not export it,
    so this causes a build error:

    ERROR: modpost: "memory_add_physaddr_to_nid" [drivers/cxl/cxl_pmem.ko] undefined!

    Fix this by exporting that function.

    Fixes: 8c2676a5870a ("hot-add-mem x86_64: memory_add_physaddr_to_nid node fixup")
