      powerpc: Fix size of st_nlink on 64bit · 0fd7bee1
      Anton Blanchard 提交于
      commit e57f93cc (powerpc: get rid of nlink_t uses, switch to
      explicitly-sized type) changed the size of st_nlink on ppc64 from
      a long to a short, resulting in boot failures.

      nls: fix (and rename) mac NLS table files and config options · 8b8c0daa
      Linus Torvalds 提交于
      The config options in the Kconfig file (with _CODEPAGE_ in the name)
      didn't match the config option name in the Makefile (no _CODEPAGE_).
      
      And both of them were of the hard-to-read MACXYZZY variety, which made
      them hard to parse for normal humans: MACROMAN easily reads as "macro
      man", not as "Mac Roman".
      
      So rename the options to be consistent, and be NLS_MAC_xyzzy.  Rename
      the files to be mac-xyzzy.c too, and drop the "nls" part entirely (it's
      already in the directory name).

      The 'mtd_writev' interface calls the function assigned
      to the '_write' field of a given mtd device if that is
      not NULL. The block2mtd driver sets the '_writev' field
      to the 'mtd_writev' function itself and thus causes a
      endless loop.
      
      This is caused by 1dbebd32

           ->d_revalidate() by NFS, which was the major stumbling block for
           all work in that area.
         * ripping security_file_mmap() and dealing with deadlocks in the
           area; sanitizing the neighborhood of vm_mmap()/vm_munmap() in
           general.
         * ->encode_fh() switched to saner API; insane fake dentry in
           mm/cleancache.c gone.
         * assorted annotations in fs (endianness, __user)
         * parts of Artem's ->s_dirty work (jff2 and reiserfs parts)
         * ->update_time() work from Josef.
         * other bits and pieces all over the place.
      
        Normally it would've been in two or three pull requests, but
        signal.git stuff had eaten a lot of time during this cycle ;-/"
      
      Fix up trivial conflicts in Documentation/filesystems/vfs.txt (the
      'truncate_range' inode method was removed by the VM changes, the VFS
      update adds an 'update_time()' method), and in fs/btrfs/ulist.[ch] (due
      to sparse fix added twice, with other changes nearby).

      x86: get rid of calling do_notify_resume() when returning to kernel mode · 44fbbb3d
      Al Viro 提交于
      If we end up calling do_notify_resume() with !user_mode(refs), it
      does nothing (do_signal() explicitly bails out and we can't get there
      with TIF_NOTIFY_RESUME in such situations).  Then we jump to
      resume_userspace_sig, which rechecks the same thing and bails out
      to resume_kernel, thus breaking the loop.
      
      It's easier and cheaper to check *before* calling do_notify_resume()
      and bail out to resume_kernel immediately.  And kill the check in
      do_signal()...
      
      Note that on amd64 we can't get there with !user_mode() at all - asm
      glue takes care of that.

      new helper: signal_delivered() · efee984c
      Al Viro 提交于
      Does block_sigmask() + tracehook_signal_handler();  called when
      sigframe has been successfully built.  All architectures converted
      to it; block_sigmask() itself is gone now (merged into this one).
      
      I'm still not too happy with the signature, but that's a separate
      story (IMO we need a structure that would contain signal number +
      siginfo + k_sigaction, so that get_signal_to_deliver() would fill one,
      signal_delivered(), handle_signal() and probably setup...frame() -
      take one).
