[PATCH] spapr: change default interrupt mode back to 'xics'

[Lijun Pan]

The hugetlbfs hugepage leakage is found under following test procedures:
1. configure hugetlbfs to back guest memory with '-mem-path /dev/hugepages'
2. hot plug a vcpu and remove it, then quit the guest.
3. hugepage leaks found on the host

git bisect points to the first bad commit: bd94bc064.
