Subject: mm/sparse: fix "unused function 'pgdat_to_phys'" warning
Date: Sat, 21 Jan 2023 12:11:51 +0200
W=1 build with clangs complains:
mm/sparse.c:347:27: warning: unused function 'pgdat_to_phys' [-Wunused-function]
static inline phys_addr_t pgdat_to_phys(struct pglist_data *pgdat)
^
1 warning generated.
pgdat_to_phys() is only used by functions defined when
CONFIG_MEMORY_HOTREMOVE=y.
Move pgdat_to_phys() under #ifdef CONFIG_MEMORY_HOTREMOVE
to make clang happy.
