S390's <asm/facility.h> uses the min_t() macro, so it should
include <linux/minmax.h> to avoid build errors.
In file included from arch/s390/pci/pci_insn.c:12:
arch/s390/include/asm/facility.h: In function '__stfle':
arch/s390/include/asm/facility.h:98:22: error: implicit declaration of
function 'min_t' [-Werror=implicit-function-declaration]
98 | nr = min_t(unsigned long, (nr + 1) * 8, size * 8);
arch/s390/include/asm/facility.h:98:28: error: expected expression
before 'unsigned'
98 | nr = min_t(unsigned long, (nr + 1) * 8, size * 8);
Fixes: 4f18d869ffd0 ("s390: fix stfle zero padding")
