[PATCH 5.10 179/390] ia64: export memory_add_physaddr_to_nid to fix cxl build error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

[ 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")
