[PATCH 2/2] x86/mm/numa: Update format specifiers in amd_numa_init()

From: Thorsten Blum

Date: Sun Jul 05 2026 - 13:17:36 EST


Use %u instead of %d as format specifiers when printing numnodes and
nodeid values, which are both unsigned integers.

Use %llx instead of %Lx for the u64 base and limit values.
