On most architectures division is an expensive operation and accessing an
element currently requires four of them. This performance penalty
effectively precludes flex arrays from being used on any kind of fast
path. However, two of these divisions can be handled at creation time and
the others can be replaced by a reciprocal divide, completely avoiding
real divisions on access.[eparis@redhat.com: rebase on top of changes to support 0 len elements]
[eparis@redhat.com: initialize part_nr when array fits entirely in base]

We plan to remove cpus_xx() old cpumask APIs later. Also, we plan to
change mm_cpu_mask() implementation, allocate only nr_cpu_ids, thus
*mm_cpu_mask() is dangerous operation.Then, this patch convert them.

Since this cred was not created with copy_creds(), it needs to get
initialized. Otherwise use of syscall(__NR_keyctl, KEYCTL_SESSION_TO_PARENT);
can lead to a NULL deref. Thanks to Robert for finding this.But introduced by commit 47a150edc2a ("Cache user_ns in struct cred").

I stupidly broke the case of CONFIG_HUGETLBFS=n when doing the
conversion to vm_flags_t in commit ca16d140af91 ("mm: don't access
vm_flags as 'int'"). And my 'allyesconfig' build didn't find it, for
obvious reasons..Include in . The problem could have
been avoided by just turning the hugetlb_file_setup() error wrapper into
a macro, but mm_types.h is a reasonable include in this file.Reported-by: Richard -rw- Weinberger
