      media: atomisp: stop producing hundreds of kernel-doc warnings · d929fb4e
      Mauro Carvalho Chehab authored
      A recent change on Kernel 4.15-rc1 causes all tags with
      /** to be handled as kernel-doc markups. Well, several
      atomisp modules, it doesn't use kernel-doc, but some other
      documentation markup (doxygen?).
      
      So, suppress all those warns by:
      	- replacing /**< by /**.
      	- replacing /** by /*.
      
      The core changes were done with:
      
      	for i in $(find drivers/staging/media/atomisp -type f); do sed 's,/\*\* ,/\*, ' -i $i; done
      	for i in $(find drivers/staging/media/atomisp -type f); do sed 's,/\*\*<,/\**,' -i $i; done
      	for i in drivers/staging/media/atomisp/pci/atomisp2/css2400/runtime/debug/src/ia_css_debug.c drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_sp.c drivers/staging/media/atomisp/pci/atomisp2/css2400/runtime/rmgr/src/rmgr_vbuf.c; do perl -ne 's,\/\*\*$,/*,g; print $_'  $i > a && mv a $i; done;
      
      A few manual adjustments were made, where needed.

      While it would be very cool to have those functions using
      kernel-doc markups, the reality right now is that they
      don't follow kernel-doc rules, as parameters aren't documented.
      
      So, stop abusing on "/**" markups.

      Those drivers use a different notation for comments. While

      ARM: BUG if jumping to usermode address in kernel mode · 8bafae20
      Russell King authored
      Detect if we are returning to usermode via the normal kernel exit paths
      but the saved PSR value indicates that we are in kernel mode.  This
      could occur due to corrupted stack state, which has been observed with
      "ftracetest".
      
      This ensures that we catch the problem case before we get to user code.

        There's one more fix for the >128T handling on hash. Once a process
        had requested a single mmap above 128T we would then always search
        above 128T. The correct behaviour is to consider the hint address in
        isolation for each mmap request.

       "This series is predominantly bug-fixes, with a few small improvements
        that have been outstanding over the last release cycle.
      
        As usual, the associated bug-fixes have CC' tags for stable.
      
        Also, things have been particularly quiet wrt new developments the
        last months, with most folks continuing to focus on stability atop 4.x
        stable kernels for their respective production configurations.
      
        Also at this point, the stable trees have been synced up with
        mainline. This will continue to be a priority, as production users
        tend to run exclusively atop stable kernels, a few releases behind
        mainline.

      afs: Fix signal handling in some file ops · 4433b691
      David Howells authored
      afs_mkdir(), afs_create(), afs_link() and afs_symlink() all need to drop
      the target dentry if a signal causes the operation to be killed immediately
      before we try to contact the server.

      afs: Fix some dentry handling in dir ops and missing key_puts · bc1527dc
      David Howells authored
      Fix some of dentry handling in AFS directory ops:
      
       (1) Do d_drop() on the new_dentry before assigning a new inode to it in
           afs_vnode_new_inode().  It's fine to do this before calling afs_iget()
           because the operation has taken place on the server.
      
       (2) Replace d_instantiate()/d_rehash() with d_add().
      
       (3) Don't d_drop() the new_dentry in afs_rename() on error.
      
      Also fix afs_link() and afs_rename() to call key_put() on all error paths
      where the key is taken.

      afs: Make afs_write_begin() avoid writing to a page that's being stored · 5a039c32
      David Howells authored
      Make afs_write_begin() wait for a page that's marked PG_writeback because:
      
       (1) We need to avoid interference with the data being stored so that the
           data on the server ends up in a defined state.
      
       (2) page->private is used to track the window of dirty data within a page,
           but it's also used by the storage code to track what's being written,
           being cleared by the completion notification.  Ownership can't be
           relinquished by the storage code until completion because it a store
           fails, the data must be remarked dirty.
      
      Tracing shows something like the following (edited):

      The clear (completion) corresponding to the store+ (store continuation from
      a previous page) happens between the second begin (afs_write_begin) and the
      store corresponding to that.  This results in the second store not seeing
      any data to write back, leading to the following warning:
