Re: [PATCH v4 00/11] hugetlb: Factorize hugetlb architecture primitives

[Alex Ghiti]

Hi everyone,

This is the result of the build for all arches tackled in this series 
rebased on 4.18-rc6:

arm:
        versatile_defconfig: without huge page OK
        keystone_defconfig: with huge page OK
arm64:
        defconfig: with huge page OK
ia64:
        generic_defconfig: with huge page OK
mips:
        Paul Burton tested cavium octeon with huge page OK
parisc:
        generic-64bit_defconfig: with huge page does not link
        generic-64bit_defconfig: without huge page does not link
        BUT not because of this series, any feedback welcome.
powerpc:
        ppc64_defconfig: without huge page OK
        ppc64_defconfig: with huge page OK
sh:
        dreamcast_defconfig: with huge page OK
sparc:
        sparc32_defconfig: without huge page OK
sparc64:
        sparc64_defconfig: with huge page OK
x86:
        with huge page OK
