      "message": "PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architectures\n\nOn 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit\nboundary. For example:\n\n\tu64 val \u003d PAGE_ALIGN(size);\n\nalways returns a value \u003c 4GB even if size is greater than 4GB.\n\nThe problem resides in PAGE_MASK definition (from include/asm-x86/page.h for\nexample):\n\n#define PAGE_SHIFT      12\n#define PAGE_SIZE       (_AC(1,UL) \u003c\u003c PAGE_SHIFT)\n#define PAGE_MASK       (~(PAGE_SIZE-1))\n...\n#define PAGE_ALIGN(addr)       (((addr)+PAGE_SIZE-1)\u0026PAGE_MASK)\n\nThe \"~\" is performed on a 32-bit value, so everything in \"and\" with\nPAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.\nUsing the ALIGN() macro seems to be the right way, because it uses\ntypeof(addr) for the mask.\n\nAlso move the PAGE_ALIGN() definitions out of include/asm-*/page.h in\ninclude/linux/mm.h.\n\nSee also lkml discussion: http://lkml.org/lkml/2008/6/11/237\n\n[akpm@linux-foundation.org: fix drivers/media/video/uvc/uvc_queue.c]\n[akpm@linux-foundation.org: fix v850]\n[akpm@linux-foundation.org: fix powerpc]\n[akpm@linux-foundation.org: fix arm]\n[akpm@linux-foundation.org: fix mips]\n[akpm@linux-foundation.org: fix drivers/media/video/pvrusb2/pvrusb2-dvb.c]\n[akpm@linux-foundation.org: fix drivers/mtd/maps/uclinux.c]\n[akpm@linux-foundation.org: fix powerpc]\nSigned-off-by: Andrea Righi \u003crighi.andrea@gmail.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": "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"
