Subject: [PATCH 0/5] Remove s390 sw-emulated hugepages and cleanup
Hi everyone,
there is a potential bug with KVM and hugetlbfs if the hardware does not
support hugepages (EDAT1).
We fix this by making EDAT1 a hard requirement for hugepages and
therefore removing and simplifying code.
As s390, with the sw-emulated hugepages, was the only user of arch_prepare/release_hugepage
I also removed theses calls from common and other architecture code.
Thanks,
Dominik
