These writes to\n  the struct page could cause excessive cacheline bouncing on big\n  systems.  There are a number of ways this could be addressed if it is\n  an issue.\n\nAnd indeed this cacheline bouncing has shown up on large SGI systems.\nThere was a situation where an Altix system was essentially livelocked\ntearing down ZERO_PAGE pagetables when an HPC app aborted during startup.\nThis situation can be avoided in userspace, but it does highlight the\npotential scalability problem with refcounting ZERO_PAGE, and corner\ncases where it can really hurt (we don\u0027t want the system to livelock!).\n\nThere are several broad ways to fix this problem:\n1. add back some special casing to avoid refcounting ZERO_PAGE\n2. per-node or per-cpu ZERO_PAGES\n3. remove the ZERO_PAGE completely\n\nI will argue for 3. The others should also fix the problem, but they\nresult in more complex code than does 3, with little or no real benefit\nthat I can see.\n\nWhy? Inserting a ZERO_PAGE for anonymous read faults appears to be a\nfalse optimisation: if an application is performance critical, it would\nnot be doing many read faults of new memory, or at least it could be\nexpected to write to that memory soon afterwards. If cache or memory use\nis critical, it should not be working with a significant number of\nZERO_PAGEs anyway (a more compact representation of zeroes should be\nused).\n\nAs a sanity check -- mesuring on my desktop system, there are never many\nmappings to the ZERO_PAGE (eg. 2 or 3), thus memory usage here should not\nincrease much without it.\n\nWhen running a make -j4 kernel compile on my dual core system, there are\nabout 1,000 mappings to the ZERO_PAGE created per second, but about 1,000\nZERO_PAGE COW faults per second (less than 1 ZERO_PAGE mapping per second\nis torn down without being COWed). So removing ZERO_PAGE will save 1,000\npage faults per second when running kbuild, while keeping it only saves\nless than 1 page clearing operation per second. 1 page clear is cheaper\nthan a thousand faults, presumably, so there isn\u0027t an obvious loss.\n\nNeither the logical argument nor these basic tests give a guarantee of no\nregressions. However, this is a reasonable opportunity to try to remove\nthe ZERO_PAGE from the pagefault path. If it is found to cause regressions,\nwe can reintroduce it and just avoid refcounting it.\n\nThe /dev/zero ZERO_PAGE usage and TLB tricks also get nuked.  I don\u0027t see\nmuch use to them except on benchmarks.  All other users of ZERO_PAGE are\nconverted just to use ZERO_PAGE(0) for simplicity. We can look at\nreplacing them all and maybe ripping out ZERO_PAGE completely when we are\nmore satisfied with this solution.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus \"snif\" Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "[PATCH] /dev/mem: validate mmap requests\n\nAdd a hook so architectures can validate /dev/mem mmap requests.\n\nThis is analogous to validation we already perform in the read/write\npaths.\n\nThe identity mapping scheme used on ia64 requires that each 16MB or\n64MB granule be accessed with exactly one attribute (write-back or\nuncacheable).  This avoids \"attribute aliasing\", which can cause a\nmachine check.\n\nSample problem scenario:\n  - Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K\n  - efi_memmap_init() discards any write-back (WB) memory in the first granule\n  - Application (e.g., \"hwinfo\") mmaps /dev/mem, offset 0\n  - hwinfo receives UC mapping (the default, since memmap says \"no WB here\")\n  - Machine check abort (on chipsets that don\u0027t support UC access to WB\n    memory, e.g., sx1000)\n\nIn the scenario above, the only choices are\n  - Use WB for hwinfo mmap.  Can\u0027t do this because it causes attribute\n    aliasing with the UC mapping for the VGA MMIO space.\n  - Use UC for hwinfo mmap.  Can\u0027t do this because the chipset may not\n    support UC for that region.\n  - Disallow the hwinfo mmap with -EINVAL.  That\u0027s what this patch does.\n\nSigned-off-by: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

We start with a pfn in mmap_mem(), so there\u0027s no\nneed to convert to an address; in fact, it\u0027s actively bad, since the\nconversion can overflow when the address is above 4G.\n\nSimilarly fix the ppc32 page_is_ram() function to avoid a conversion to an\naddress by directly comparing to max_pfn.
