Hi All, This series contains some fixes for hugetlb on arm64. It turns out that I will need to rework the companion performance improvement series a bit and as a result won't be relying on the purely mm fix that was patch 4 in v2. So I've dropped that patch and will send it to mm separately. I think this should be ready for merge now. Changes since v2 [2] ==================== - Added Rb/Ab from various people - Thanks! - Reworked num_contig_ptes() to return 1 by default and warn for bad sizes - Fixed some formatting issues in s390 header - Moved s390's huge_ptep_get_and_clear() to header and made it inline - Removed patch 4; I'll send this to mm list separately - Fixed various typos in commit logs Changes since v1 [1] ==================== - Added Rb from Anshuman - Thanks! - Added "#ifndef __PAGETABLE_PMD_FOLDED" around PUD_SIZE in flush_hugetlb_tlb_range() I've marked all of these as candidates for backport to stable. Applies on top of v6.14-rc3. All mm selftests run and pass.
