Revert "hugetlb: make hugetlb depends on SYSFS or SYSCTL"
Commit f8142cf94d47 ("hugetlb: make hugetlb depends on SYSFS or SYSCTL")
added dependency on SYSFS or SYSCTL but hugetlb can be used without SYSFS
or SYSCTL. So this dependency is wrong and should be removed.
For users with CONFIG_SYSFS or CONFIG_SYSCTL on, there should be no
difference. For users have CONFIG_SYSFS and CONFIG_SYSCTL both
undefined, hugetlbfs can still works perfectly well through cmdline
except a possible kismet warning[1] when select CONFIG_HUGETLBFS.
IMHO, it might not worth a backport.
This reverts commit f8142cf94d4737ea0c3baffb3b9bad8addcb9b6b. It
overlooked the scenario of using hugetlb through boot parameters when
it was submitted.
