These macros can be helpful when we plan to merge hugetlb code into generic
code. Move them out and define them even if !THP.
We actually already defined HPAGE_PMD_NR for other reasons even if !THP.
Reorganize these macros.

ARM defines pmd_thp_or_huge(), detecting either a THP or a huge PMD. It
can be a helpful helper if we want to merge more THP and hugetlb code
paths. Make it a generic default implementation, only exist when
CONFIG_MMU. Arch can overwrite it by defining its own version.

It will be used outside hugetlb.c soon.

Introduce a config option that will be selected as long as huge leaves are
involved in pgtable (thp or hugetlbfs). It would be useful to mark any
code with this new config that can process either hugetlb or thp pages in
any level that is higher than pte level.

This is v1 of the series. The series removes the hugetlb slow gup path
after a previous refactor work [1], so that slow gup now uses the exact
same path to handle all kinds of memory including hugetlb.
It's based on latest mm-unstalbe (c13bdc82ada9).

Adapt the driver to work with configurations using two codecs or more.
Modify fsl_asoc_card_probe() to handle use cases where 2 codecs are
given in the device tree.
This will be needed for the generic codec case.
Use cases using one codec will ignore any given codecs other than the
first.

Hello,
This is the v3 of the series of patch aiming to make the machine driver
"fsl-asoc-card" compatible with use cases where there is no real codec
driver.
It proposes to use the "spdif_receiver" and "spdif_transmitter"
drivers instead of the dummy codec.
This is a first step in using the S/PDIF
