When implementing support for SVE,\nconditional code was added to this function in order to handle the\ncase where SVE state need to be loaded for the task and merged with\nthe FPSIMD data from the signal frame; however, the FPSIMD-only\ncase was unintentionally dropped.\n\nAs a result of this, sigreturn does not currently restore the\nFPSIMD state of the task, except in the case where the system\nsupports SVE and the signal frame contains SVE state in addition to\nFPSIMD state.\n\nThis patch fixes this bug by making the copy-in of the FPSIMD data\nfrom the signal frame to thread_struct unconditional.\n\nThis remains a performance regression from v4.14, since the FPSIMD\nstate is now copied into thread_struct and then loaded back,\ninstead of _only_ being loaded into the CPU FPSIMD registers.\nHowever, it is essential to call task_fpsimd_load() here anyway in\norder to ensure that the SVE enable bit in CPACR_EL1 is set\ncorrectly before returning to userspace. This could use some\nrefactoring, but since sigreturn is not a fast path I have kept\nthis patch as a pure fix and left the refactoring for later.\n\nCc: Catalin Marinas \u003ccatalin.marinas@arm.com\u003e\nCc: Ard Biesheuvel \u003card.biesheuvel@linaro.org\u003e\nFixes: 8cd969d28fd2 (\"arm64/sve: Signal handling support\")\nReported-by: Alex Bennée \u003calex.bennee@linaro.org\u003e\nTested-by: Alex Bennée \u003calex.bennee@linaro.org\u003e\nReviewed-by: Alex Bennée \u003calex.bennee@linaro.org\u003e\nSigned-off-by: Dave Martin \u003cDave.Martin@arm.com\u003e\nSigned-off-by: Will Deacon \u003cwill.deacon@arm.com\u003e\n" }, { "commit": "a349b30250634da20950eb91e2551dcd81f1805d", "tree": "42c7f95a9e464d2cd31a3141b6bcd3699e17120b", "parents": [ "be0f272bfc83797f70d44faca86954df62e2bbc0" ], "author": { "name": "Jinbum Park", "email": "jinb.park7@gmail.com", "time": "Wed Nov 22 21:43:59 2017 +0900" }, "committer": { "name": "Will Deacon", "email": "will.deacon@arm.com", "time": "Fri Dec 01 13:05:04 2017 +0000" }, "message": "arm64: pgd: Mark pgd_cache as __ro_after_init\n\npgd_cache is setup once while init stage and never changed after\nthat, so it is good candidate for __ro_after_init\n\nSigned-off-by: Jinbum Park \u003cjinb.park7@gmail.com\u003e\nSigned-off-by: Will Deacon \u003cwill.deacon@arm.com\u003e\n" }, { "commit": "be0f272bfc83797f70d44faca86954df62e2bbc0", "tree": "cc30988986ef959c80ad89912f5dc342f99f0be5", "parents": [ "7e8b9c1d2e2f5f45db7d40b50d14f606097c25de" ], "author": { "name": "Ard Biesheuvel", "email": "ard.biesheuvel@linaro.org", "time": "Mon Nov 20 17:41:30 2017 +0000" }, "committer": { "name": "Will Deacon", "email": "will.deacon@arm.com", "time": "Fri Dec 01 13:04:59 2017 +0000" }, "message": "arm64: ftrace: emit ftrace-mod.o contents through code\n\nWhen building the arm64 kernel with both CONFIG_ARM64_MODULE_PLTS and\nCONFIG_DYNAMIC_FTRACE enabled, the ftrace-mod.o object file is built\nwith the kernel and contains a trampoline that is linked into each\nmodule, so that modules can be loaded far away from the kernel and\nstill reach the ftrace entry point in the core kernel with an ordinary\nrelative branch, as is emitted by the compiler instrumentation code\ndynamic ftrace relies on.\n\nIn order to be able to build out of tree modules, this object file\nneeds to be included into the linux-headers or linux-devel packages,\nwhich is undesirable, as it makes arm64 a special case (although a\nprecedent does exist for 32-bit PPC).\n\nGiven that the trampoline essentially consists of a PLT entry, let\u0027s\nnot bother with a source or object file for it, and simply patch it\nin whenever the trampoline is being populated, using the existing\nPLT support routines.\n\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Ard Biesheuvel \u003card.biesheuvel@linaro.org\u003e\nSigned-off-by: Will Deacon \u003cwill.deacon@arm.com\u003e\n" }, { "commit": "7e8b9c1d2e2f5f45db7d40b50d14f606097c25de", "tree": "bbce43dfb8ebcfc44fcfb837363205628a608592", "parents": [ "f81a348728ec5ac43f3bbcf81c97d52baba253f7" ], "author": { "name": "Ard Biesheuvel", "email": "ard.biesheuvel@linaro.org", "time": "Mon Nov 20 17:41:29 2017 +0000" }, "committer": { "name": "Will Deacon", "email": "will.deacon@arm.com", "time": "Fri Dec 01 12:30:21 2017 +0000" }, "message": "arm64: module-plts: factor out PLT generation code for ftrace\n\nTo allow the ftrace trampoline code to reuse the PLT entry routines,\nfactor it out and move it into asm/module.h.\n\nCc: \u003cstable@vger.kernel.org\u003e\nSigned-off-by: Ard Biesheuvel \u003card.biesheuvel@linaro.org\u003e\nSigned-off-by: Will Deacon \u003cwill.deacon@arm.com\u003e\n" }, { "commit": "f8de483e7440b0d23ce6372b3ef8358841c8827b", "tree": "7c1f01841c8171313af72a3f378393f916493032", "parents": [ "1bcab12521d9b23dbaa22ac71184778dcc43e2f6" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Dec 01 11:40:43 2017 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Fri Dec 01 11:51:24 2017 +0000" }, "message": "afs: Properly reset afs_vnode (inode) fields\n\nWhen an AFS inode is allocated by afs_alloc_inode(), the allocated\nafs_vnode struct isn\u0027t necessarily reset from the last time it was used as\nan inode because the slab constructor is only invoked once when the memory\nis obtained from the page allocator.\n\nThis means that information can leak from one inode to the next because\nwe\u0027re not calling kmem_cache_zalloc().

In order to\nmaintain correct behavior, we additionally mark every other hart as\nneeding a deferred instruction cache which will be taken before anything\nruns on it.\n\nSigned-off-by: Andrew Waterman \u003candrew@sifive.com\u003e\nSigned-off-by: Palmer Dabbelt \u003cpalmer@sifive.com\u003e\n" }, { "commit": "741fc3ff3a49509a7092d6d9eb51da6bd7577278", "tree": "a729230ff9252f69660800f9feb6cfa5028b2c65", "parents": [ "4a41d5dbb0bbd0c3faffb2ccd8ef1a7aeb12f978" ], "author": { "name": "Olof Johansson", "email": "olof@lixom.net", "time": "Wed Nov 29 17:55:20 2017 -0800" }, "committer": { "name": "Palmer Dabbelt", "email": "palmer@sifive.com", "time": "Thu Nov 30 10:34:47 2017 -0800" }, "message": "RISC-V: Add missing include\n\nFixes:\n\ninclude/asm-generic/mm_hooks.h:20:11: warning: \u0027struct vm_area_struct\u0027 declared inside parameter list will not be visible outside of this definition or declaration\ninclude/asm-generic/mm_hooks.h:19:38: warning: \u0027struct mm_struct\u0027 declared inside parameter list will not be visible outside of this definition or declaration\n\nSigned-off-by: Olof Johansson \u003colof@lixom.net\u003e\nSigned-off-by: Palmer Dabbelt \u003cpalmer@sifive.com\u003e\n" }, { "commit": "4a41d5dbb0bbd0c3faffb2ccd8ef1a7aeb12f978", "tree": "7be1afce63369d5a6caf0ff85e15af36b7b53dc0", "parents": [ "4bde63286a6c7c76fe05ff0e03ad253f5260b104" ], "author": { "name": "Olof Johansson", "email": "olof@lixom.net", "time": "Wed Nov 29 17:55:18 2017 -0800" }, "committer": { "name": "Palmer Dabbelt", "email": "palmer@sifive.com", "time": "Thu Nov 30 10:12:21 2017 -0800" }, "message": "RISC-V: Use define for get_cycles like other architectures\n\nSigned-off-by: Olof Johansson \u003colof@lixom.net\u003e\nSigned-off-by: Palmer Dabbelt \u003cpalmer@sifive.com\u003e\n" }, { "commit": "4bde63286a6c7c76fe05ff0e03ad253f5260b104", "tree": "d5999cd73c4963a7833fd2ab7c239652f8919d32", "parents": [ "24948b7ec0f31d36dc900088b140c4f9551b6f56" ], "author": { "name": "Olof Johansson", "email": "olof@lixom.net", "time": "Wed Nov 29 17:55:17 2017 -0800" }, "committer": { "name": "Palmer Dabbelt", "email": "palmer@sifive.com", "time": "Thu Nov 30 10:12:15 2017 -0800" }, "message": "RISC-V: Provide stub of setup_profiling_timer()\n\nFixes the following on allmodconfig build:\n\nprofile.c:(.text+0x3e4): undefined reference to `setup_profiling_timer\u0027\n\nSigned-off-by: Olof Johansson \u003colof@lixom.net\u003e\nSigned-off-by: Palmer Dabbelt \u003cpalmer@sifive.com\u003e\n" }, { "commit": "24948b7ec0f31d36dc900088b140c4f9551b6f56", "tree": "2780c30a0db0a18e2509e999cc61846c2d5efbe3", "parents": [ "83e7b8769a08987f47117f3a065de153c839a0a8" ], "author": { "name": "Olof Johansson", "email": "olof@lixom.net", "time": "Wed Nov 29 17:55:16 2017 -0800" }, "committer": { "name": "Palmer Dabbelt", "email": "palmer@sifive.com", "time": "Thu Nov 30 10:01:10 2017 -0800" }, "message": "RISC-V: Export some expected symbols for modules\n\nThese are the ones needed by current allmodconfig, so add them instead\nof everything other architectures are exporting -- the rest can be\nadded on demand later if needed.\n\nSigned-off-by: Olof Johansson \u003colof@lixom.net\u003e\nSigned-off-by: Palmer Dabbelt \u003cpalmer@sifive.com\u003e\n" }, { "commit": "83e7b8769a08987f47117f3a065de153c839a0a8", "tree": "77572dca79811be32baf6662edd9654fe766f28f", "parents": [ "fe2726af9fdc93ecf2469b7c512fc1a8936e128c" ], "author": { "name": "Olof Johansson", "email": "olof@lixom.net", "time": "Wed Nov 29 17:55:15 2017 -0800" }, "committer": { "name": "Palmer Dabbelt", "email": "palmer@sifive.com", "time": "Thu Nov 30 10:01:10 2017 -0800" }, "message": "RISC-V: move empty_zero_page definition to C and export it\n\nNeeded by some modules (exported by other architectures).\n\nSigned-off-by: Olof Johansson \u003colof@lixom.net\u003e\nSigned-off-by: Palmer Dabbelt \u003cpalmer@sifive.com\u003e\n" }, { "commit": "fe2726af9fdc93ecf2469b7c512fc1a8936e128c", "tree": "0c745c6770c3ca0a4c0db509cd43387f58d0fb8c", "parents": [ "5e6f82b0fe7b7b4a204efeb0817fb8b0a2bc0373" ], "author": { "name": "Olof Johansson", "email": "olof@lixom.net", "time": "Wed Nov 29 17:55:14 2017 -0800" }, "committer": { "name": "Palmer Dabbelt", "email": "palmer@sifive.com", "time": "Thu Nov 30 10:01:10 2017 -0800" }, "message": "RISC-V: io.h: type fixes for warnings\n\ninclude \u003clinux/types.h\u003e for __iomem definition.
