      ARCH: drivers remove __dev* attributes. · b881bc46
      Greg Kroah-Hartman 提交于
      This fixes up all of the smaller arches that had __dev* markings for
      their platform-specific drivers.
      
      CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
      markings need to be removed.
      
      This change removes the use of __devinit, __devexit_p, __devinitdata,
      __devinitconst, and __devexit from these drivers.
      
      Based on patches originally written by Bill Pemberton, but redone by me
      in order to handle some of the coding style issues better, by hand.

      mm: support more pagesizes for MAP_HUGETLB/SHM_HUGETLB · 42d7395f
      Andi Kleen 提交于
      There was some desire in large applications using MAP_HUGETLB or
      SHM_HUGETLB to use 1GB huge pages on some mappings, and stay with 2MB on
      others.  This is useful together with NUMA policy: use 2MB interleaving
      on some mappings, but 1GB on local mappings.
      
      This patch extends the IPC/SHM syscall interfaces slightly to allow
      specifying the page size.
      
      It borrows some upper bits in the existing flag arguments and allows
      encoding the log of the desired page size in addition to the *_HUGETLB
      flag.  When 0 is specified the default size is used, this makes the
      change fully compatible.
      
      Extending the internal hugetlb code to handle this is straight forward.
      Instead of a single mount it just keeps an array of them and selects the
      right mount based on the specified page size.  When no page size is
      specified it uses the mount of the default page size.
      
      The change is not visible in /proc/mounts because internal mounts don't
      appear there.  It also has very little overhead: the additional mounts
      just consume a super block, but not more memory when not used.
      
      I also exported the new flags to the user headers (they were previously
      under __KERNEL__).  Right now only symbols for x86 and some other
      architecture for 1GB and 2MB are defined.  The interface should already
      work for all other architectures though.  Only architectures that define
      multiple hugetlb sizes actually need it (that is currently x86, tile,
      powerpc).  However tile and powerpc have user configurable hugetlb
      sizes, so it's not easy to add defines.  A program on those
      architectures would need to query sysfs and use the appropiate log2.

      sk-filter: Add ability to get socket filter program (v2) · a8fc9277
      Pavel Emelyanov 提交于
      The SO_ATTACH_FILTER option is set only. I propose to add the get
      ability by using SO_ATTACH_FILTER in getsockopt. To be less
      irritating to eyes the SO_GET_FILTER alias to it is declared. This
      ability is required by checkpoint-restore project to be able to
      save full state of a socket.
      
      There are two issues with getting filter back.
      
      First, kernel modifies the sock_filter->code on filter load, thus in
      order to return the filter element back to user we have to decode it
      into user-visible constants. Fortunately the modification in question
      is interconvertible.
      
      Second, the BPF_S_ALU_DIV_K code modifies the command argument k to
      speed up the run-time division by doing kernel_k = reciprocal(user_k).
      Bad news is that different user_k may result in same kernel_k, so we
      can't get the original user_k back. Good news is that we don't have
      to do it. What we need to is calculate a user2_k so, that
      
        reciprocal(user2_k) == reciprocal(user_k) == kernel_k
      
      i.e. if it's re-loaded back the compiled again value will be exactly
      the same as it was. That said, the user2_k can be calculated like this
      
        user2_k = reciprocal(kernel_k)
      
      with an exception, that if kernel_k == 0, then user2_k == 1.
      
      The optlen argument is treated like this -- when zero, kernel returns
      the amount of sock_fprog elements in filter, otherwise it should be
      large enough for the sock_fprog array.
      
      changes since v1:
      * Declared SO_GET_FILTER in all arch headers
      * Added decode of vlan-tag codes

      compat: move compat_siginfo_t definition to asm/compat.h · 751f409d
      Denys Vlasenko 提交于
      This is a preparatory patch for the introduction of NT_SIGINFO elf note.
      
      Make the location of compat_siginfo_t uniform across eight architectures
      which have it.  Now it can be pulled in by including asm/compat.h or
      linux/compat.h.
      
      Most of the copies are verbatim.  compat_uid[32]_t had to be replaced by
      __compat_uid[32]_t.  compat_uptr_t had to be moved up before
      compat_siginfo_t in asm/compat.h on a several architectures (tile already
      had it moved up).  compat_sigval_t had to be relocated from linux/compat.h
      to asm/compat.h.

      Make most arch asm/module.h files use asm-generic/module.h · 786d35d4
      David Howells 提交于
      Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
      ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
      into asm-generic/module.h for all arches bar MIPS.
      
      Also, use the generic definition mod_arch_specific where possible.
      
      To this end, I've defined three new config bools:
      
       (*) HAVE_MOD_ARCH_SPECIFIC
      
           Arches define this if they don't want to use the empty generic
           mod_arch_specific struct.
      
       (*) MODULES_USE_ELF_RELA
      
           Arches define this if their modules can contain RELA records.  This causes
           the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
           defined by the arch rather than have the core emit an error message.
      
       (*) MODULES_USE_ELF_REL
      
           Arches define this if their modules can contain REL records.  This causes
           the Elf_Rel mapping to be emitted and allows apply_relocate() to be
           defined by the arch rather than have the core emit an error message.
      
      Note that it is possible to allow both REL and RELA records: m68k and mips are
      two arches that do this.
      
      With this, some arch asm/module.h files can be deleted entirely and replaced
      with a generic-y marker in the arch Kbuild file.
      
      Additionally, I have removed the bits from m32r and score that handle the
      unsupported type of relocation record as that's now handled centrally.

      [PARISC] Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts · bba3d8c3
      Mel Gorman 提交于
      The following build error occured during a parisc build with
      swap-over-NFS patches applied.
      
      net/core/sock.c:274:36: error: initializer element is not constant
      net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks')
      net/core/sock.c:274:36: error: initializer element is not constant
      
      Dave Anglin says:
      > Here is the line in sock.i:
      >
      > struct static_key memalloc_socks = ((struct static_key) { .enabled =
      > ((atomic_t) { (0) }) });
      
      The above line contains two compound literals.  It also uses a designated
      initializer to initialize the field enabled.  A compound literal is not a
      constant expression.
      
      The location of the above statement isn't fully clear, but if a compound
      literal occurs outside the body of a function, the initializer list must
      consist of constant expressions.
