Merge "mm: Kconfig: Add support for config size of purging vmap_area"

	  information to userspace via debugfs.

	  If unsure, say N.

config VMAP_LAZY_PURGING_FACTOR

	int "multiplier to the size of purged vmap areas"

	default "8" if ARM

	default "32"

	help

	  It is used as a multiplier to the max VA pages purged in a

	  single attempt. For 32-bit in order to reduce fragmentation

	  of vmalloc space, we decrease the default value to "8".

	log = fls(num_online_cpus());

	return log * (32UL * 1024 * 1024 / PAGE_SIZE);

	return log * (1UL * CONFIG_VMAP_LAZY_PURGING_FACTOR *

					1024 * 1024 / PAGE_SIZE);
