Subject: hugetlb: harmonize hugetlb.h arch specific defines with pgtable.h
In order to reduce copy/paste of functions across architectures and then
make riscv hugetlb port (and future ports) simpler and smaller, this
patchset intends to factorize the numerous hugetlb primitives that are
defined across all the architectures.
Except for prepare_hugepage_range, this patchset moves the versions that
are just pass-through to standard pte primitives into
asm-generic/hugetlb.h by using the same #ifdef semantic that can be found
in asm-generic/pgtable.h, i.e. __HAVE_ARCH_***.
s390 architecture has not been tackled in this serie since it does not use
asm-generic/hugetlb.h at all.
This patchset has been compiled on all addressed architectures with
success (except for parisc, but the problem does not come from this
series).
This patch (of 11):
asm-generic/hugetlb.h proposes generic implementations of hugetlb related
functions: use __HAVE_ARCH_HUGE* defines in order to make arch specific
implementations of hugetlb functions consistent with pgtable.h scheme.
