David has a testing a\nTLP monitor he was writing for an FPGA, and has been occasionally\ncomplaining about how memcpy_toio() writes things one byte at a time.\n\nWhich is completely unacceptable from a performance standpoint, even if\nit happens to technically work.\n\nThe reason it\u0027s writing one byte at a time is because while it\u0027s\ntechnically true that accesses to iomem are the same as accesses to\nregular memory on x86, the _granularity_ (and ordering) of accesses\nmatter to iomem in ways that they don\u0027t matter to regular cached memory.\n\nIn particular, when ERMS is set, we default to using \"rep movsb\" for\nlarger memory copies. That is indeed perfectly fine for real memory,\nsince the whole point is that the CPU is going to do cacheline\noptimizations and executes the memory copy efficiently for cached\nmemory.\n\nWith iomem? Not so much. With iomem, \"rep movsb\" will indeed work, but\nit will copy things one byte at a time. Slowly and ponderously.\n\nNow, originally, back in 2010 when commit 6175ddf06b61 was done, we\ndidn\u0027t use ERMS, and this was much less noticeable.\n\nOur normal memcpy() was simpler in other ways too.\n\nBecause in fact, it\u0027s not just about using the string instructions. Our\nmemcpy() these days does things like \"read and write overlapping values\"\nto handle the last bytes of the copy. Again, for normal memory,\noverlapping accesses isn\u0027t an issue. For iomem? It can be.\n\nSo this re-introduces the specialized memcpy_toio(), memcpy_fromio() and\nmemset_io() functions. It doesn\u0027t particularly optimize them, but it\ntries to at least not be horrid, or do overlapping accesses. In fact,\nthis uses the existing __inline_memcpy() function that we still had\nlying around that uses our very traditional \"rep movsl\" loop followed by\nmovsw/movsb for the final bytes.\n\nSomebody may decide to try to improve on it, but if we\u0027ve gone almost a\ndecade with only one person really ever noticing and complaining, maybe\nit\u0027s not worth worrying about further, once it\u0027s not _completely_ broken?\n\nReported-by: David Laight \u003cDavid.Laight@aculab.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a959dc88f9c8900296ccf13e2f3e1cbc555a8917", "tree": "8a8d5219ad5b7430107c92fe1ec3082611a5ce05", "parents": [ "4a789213c9a54c8b618924d3421e56e98df8a447" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat May 21 21:55:19 2016 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 04 18:15:25 2019 -0800" }, "message": "Use __put_user_goto in __put_user_size() and unsafe_put_user()\n\nThis actually enables the __put_user_goto() functionality in\nunsafe_put_user().\n\nFor an example of the effect of this, this is the code generated for the\n\n unsafe_put_user(signo, \u0026infop-\u003esi_signo, Efault);\n\nin the waitid() system call:\n\n\tmovl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_2]\n\nIt\u0027s just one single store instruction, along with generating an\nexception table entry pointing to the Efault label case in case that\ninstruction faults.\n\nBefore, we would generate this:\n\n\txorl %edx, %edx\n\tmovl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_3]\n testl %edx, %edx\n jne .L309\n\nwith the exception table generated for that \u0027mov\u0027 instruction causing us\nto jump to a stub that set %edx to -EFAULT and then jumped back to the\n\u0027testl\u0027 instruction.\n\nSo not only do we now get rid of the extra code in the normal sequence,\nwe also avoid unnecessarily keeping that extra error register live\nacross it all.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4a789213c9a54c8b618924d3421e56e98df8a447", "tree": "1e6775ba2fc12cb9893f09b203c85e2014de256b", "parents": [ "594cc251fdd0d231d342d88b2fdff4bc42fb0690" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat May 21 21:44:51 2016 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 04 18:00:49 2019 -0800" }, "message": "x86 uaccess: Introduce __put_user_goto\n\nThis is finally the actual reason for the odd error handling in the\n\"unsafe_get/put_user()\" functions, introduced over three years ago.\n\nUsing a \"jump to error label\" interface is somewhat odd, but very\nconvenient as a programming interface, and more importantly, it fits\nvery well with simply making the target be the exception handler address\ndirectly from the inline asm.\n\nThe reason it took over three years to actually do this?

There is concern that the extra\n\u0027address\u0027 argument that mremap passes to pte_alloc may do something\nsubtle architecture related in the future that may make the scheme not\nwork. Also we find that there is no point in passing the \u0027address\u0027 to\npte_alloc since its unused. This patch therefore removes this argument\ntree-wide resulting in a nice negative diff as well.

With gen_pool_first_fit_align()\nallocation function, the returned address should be aligned on the\nrequested boundary.\n\nIf chunk start address isn\u0027t aligned on the requested boundary, the\nreturned address isn\u0027t aligned too. The only way to get properly\naligned address is to initialize the pool with chunks aligned on the\nrequested boundary. If want to have an ability to allocate buffers\naligned on different boundaries (for example, 4K, 1MB, ...), the chunk\nstart address should be aligned on the max possible alignment.\n\nThis happens because gen_pool_first_fit_align() looks for properly\naligned memory block without taking into account the chunk start address\nalignment.\n\nTo fix this, we provide chunk start address to\ngen_pool_first_fit_align() and change its implementation such that it\nstarts looking for properly aligned block with appropriate offset\n(exactly as is done in CMA).\n\nLink: https://lkml.kernel.org/lkml/a170cf65-6884-3592-1de9-4c235888cc8a@intel.com\nLink: http://lkml.kernel.org/r/1541690953-4623-1-git-send-email-alexey.skidanov@intel.com\nSigned-off-by: Alexey Skidanov \u003calexey.skidanov@intel.com\u003e\nReviewed-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Logan Gunthorpe \u003clogang@deltatee.com\u003e\nCc: Daniel Mentz \u003cdanielmentz@google.com\u003e\nCc: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nCc: Laura Abbott \u003clabbott@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3fc2579e6f162fcff964f5aa01c8a29438ca5c05", "tree": "a90c733a19c07e111d9195181d1f3a37e92ef0eb", "parents": [ "e6310f0fb5cd3f65244dbdef2fb264859891c7ec" ], "author": { "name": "Matthew Wilcox", "email": "willy@infradead.org", "time": "Thu Jan 03 15:26:41 2019 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 04 13:13:46 2019 -0800" }, "message": "fls: change parameter to unsigned int\n\nWhen testing in userspace, UBSAN pointed out that shifting into the sign\nbit is undefined behaviour.
