x86/mm: Drop unnecessary export of "ptdump_walk_pgd_level_debugfs"

sean-jc · hansendc · commit e6f2d5866c55 · 2025-11-12T15:24:42.000-08:00
Don't export "ptdump_walk_pgd_level_debugfs" as its sole user is arch/x86/mm/debug_pagetables.c, which can't be built as a module. No functional change intended.
