# Newer kernels on s390 check for an S390_PGSTE program header and
# enable the pgste page table extensions in that case. This makes
# the vm.allocate_pgste sysctl unnecessary. We enable this program
# header if
# - we build on s390x
# - we build the system emulation for s390x (qemu-system-s390x)
# - KVM is enabled
# - the linker supports --s390-pgste
