      "message": "CONFIG_HIGHPTE vs. sub-page page tables.\n\nBackground: I\u0027ve implemented 1K/2K page tables for s390.  These sub-page\npage tables are required to properly support the s390 virtualization\ninstruction with KVM.  The SIE instruction requires that the page tables\nhave 256 page table entries (pte) followed by 256 page status table entries\n(pgste).  The pgstes are only required if the process is using the SIE\ninstruction.  The pgstes are updated by the hardware and by the hypervisor\nfor a number of reasons, one of them is dirty and reference bit tracking.\nTo avoid wasting memory the standard pte table allocation should return\n1K/2K (31/64 bit) and 2K/4K if the process is using SIE.\n\nProblem: Page size on s390 is 4K, page table size is 1K or 2K.  That means\nthe s390 version for pte_alloc_one cannot return a pointer to a struct\npage.  Trouble is that with the CONFIG_HIGHPTE feature on x86 pte_alloc_one\ncannot return a pointer to a pte either, since that would require more than\n32 bit for the return value of pte_alloc_one (and the pte * would not be\naccessible since its not kmapped).\n\nSolution: The only solution I found to this dilemma is a new typedef: a\npgtable_t.  For s390 pgtable_t will be a (pte *) - to be introduced with a\nlater patch.  For everybody else it will be a (struct page *).  The\nadditional problem with the initialization of the ptl lock and the\nNR_PAGETABLE accounting is solved with a constructor pgtable_page_ctor and\na destructor pgtable_page_dtor.  The page table allocation and free\nfunctions need to call these two whenever a page table page is allocated or\nfreed.  pmd_populate will get a pgtable_t instead of a struct page pointer.\n To get the pgtable_t back from a pmd entry that has been installed with\npmd_populate a new function pmd_pgtable is added.  It replaces the pmd_page\ncall in free_pte_range and apply_to_pte_range.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \u003clinux-arch@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "Add __GFP_MOVABLE for callers to flag allocations from high memory that may be migrated\n\nIt is often known at allocation time whether a page may be migrated or not.\nThis patch adds a flag called __GFP_MOVABLE and a new mask called\nGFP_HIGH_MOVABLE.  Allocations using the __GFP_MOVABLE can be either migrated\nusing the page migration mechanism or reclaimed by syncing with backing\nstorage and discarding.\n\nAn API function very similar to alloc_zeroed_user_highpage() is added for\n__GFP_MOVABLE allocations called alloc_zeroed_user_highpage_movable().  The\nflags used by alloc_zeroed_user_highpage() are not changed because it would\nchange the semantics of an existing API.  After this patch is applied there\nare no in-kernel users of alloc_zeroed_user_highpage() so it probably should\nbe marked deprecated if this patch is merged.\n\nNote that this patch includes a minor cleanup to the use of __GFP_ZERO in\nshmem.c to keep all flag modifications to inode-\u003emapping in the\nshmem_dir_alloc() helper function.
