Subject: [PATCH v6 00/11] hugetlb: Factorize hugetlb architecture primitives
[CC linux-mm for inclusion in -mm tree]
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).
v6:
- Remove nohash/32 and book3s/32 powerpc specific implementations in
order to use the generic ones.
- Add all the Reviewed-by, Acked-by and Tested-by in the commits,
thanks to everyone.
v5:
As suggested by Mike Kravetz, no need to move the #include
<asm-generic/hugetlb.h> for arm and x86 architectures, let it live at
the top of the file.
v4:
Fix powerpc build error due to misplacing of #include
<asm-generic/hugetlb.h> outside of #ifdef CONFIG_HUGETLB_PAGE, as
pointed by Christophe Leroy.
v1, v2, v3:
Same version, just problems with email provider and misuse of
--batch-size option of git send-email
Alexandre Ghiti (11):
hugetlb: Harmonize hugetlb.h arch specific defines with pgtable.h

hugetlb: Introduce generic version of huge_ptep_clear_flush
hugetlb: Introduce generic version of huge_pte_none
hugetlb: Introduce generic version of huge_pte_wrprotect
hugetlb: Introduce generic version of prepare_hugepage_range
hugetlb: Introduce generic version of huge_ptep_set_wrprotect
hugetlb: Introduce generic version of huge_ptep_set_access_flags
hugetlb: Introduce generic version of huge_ptep_get
