      [TG3]: Jumbo frames and FTQ reset patch. · 4712542b
      Michael Chan authored
      1. Set extended packet length bit in phy register 0x18 shadow register 0
      on all chips that support jumbo frames (i.e. all chips except 5705 and
      its variants). Jumbo frame reception is less reliable (more CRC errors)
      if this bit is not set. This bit can be set regardless of the current
      MTU setting.
      
      
      2. Remove FTQ reset during chip init. This is the best fix for the ASF
      race condition problem that I mentioned a few months ago. The FTQ reset
      is redundant as it is already reset during GRC reset.

      [PATCH] FD_CLOEXEC fcntl cleanup · dc5178fa
      David Howells authored
      This fixes a minor problem with fcntl.
      
      get_close_on_exec() uses FD_ISSET() to determine the fd state, but this
      is not guaranteed to be either 0 of FD_CLOEXEC.  Make that explicit.
      
      Also, the argument of set_close_on_exec() is being AND'ed with the
      literal constant 1.  Make it use an explicit FD_CLOEXEC test.

      [PATCH] hpfs: fix locking scheme · 9c96c8be
      Alexander Viro authored
      	Fixed the locking scheme.  The need of extra locking was caused by
      the fact that hpfs_write_inode() must update directory entry; since HPFS
      directories are implemented as b-trees, we must provide protection both
      against rename() (to make sure that we update the entry in right directory)
      and against rebalancing of the parent.
      
      	Old scheme had both deadlocks and races - to start with, we had no
      protection against rename()/unlink()/rmdir(), since (a) locking parent
      was done without any warranties that it will remain our parent and (b)
      check that we still have a directory entry (== have positive nlink) was
      done before we tried to lock the parent.  Moreover, iget serialization
      killed two steps ago gave immediate deadlocks if iget() of parent had
      triggered another hpfs_write_inode().
      
      	New scheme introduces another per-inode semaphore (hpfs-only,
      obviously) protecting the reference to parent.  It's taken on
      rename/rmdir/unlink victims and inode being moved by rename.  Old semaphores
      are taken only on parent(s) and only after we grab one(s) of the new kind.
      hpfs_write_inode() gets the new semaphore on our inode, checks nlink and
      if it's non-zero grabs parent and takes the old semaphore on it.
      
      	Order among the semaphores of the same kind is arbitrary - the only
      function that might take more than one of the same kind is hpfs_rename()
      and it's serialized by VFS.
      
      	We might get away with only one semaphore, but then the ordering
      issues would bite us big way - we would have to make sure that child is
      always locked before parent (hpfs_write_inode() leaves no other choice)
      and while that's easy to do for almost all operations, rename() is a bitch -
      as always.  And per-superblock rwsem giving rename() vs. write_inode()
      exclusion on hpfs would make the entire thing too baroque for my taste.
      	->readdir() takes no locks at all (protection against directory
      modifications is provided by VFS exclusion), ditto for ->lookup().
      	->llseek() on directories switched to use of (VFS) ->i_sem, so
      it's safe from directory modifications and ->readdir() is safe from it -
      no hpfs locks are needed here.

      [PATCH] hpfs: deadlock fixes · d9013aae
      Alexander Viro authored
      We used to have GFP_KERNEL kmalloc() done by the code that held hpfs
      lock on directory.  That could trigger a call of hpfs_write_inode() and
      deadlock; fixed by switch to GFP_NOFS.  Same for hpfs inodes themselves
      - hpfs_write_inode() calls iget() and that could trigger both the
      deadlocks (avoidable with very baroque locking scheme) and stack
      overflows (unavoidable unless we kill potential recursion here).

      [PATCH] hpfs: hpfs iget locking cleanup · 772fd530
      Alexander Viro authored
      Killed the nightmares in hpfs iget handling.  Since in some (fairly
      frequent) cases hpfs_read_inode() could avoid any IO (basically, lookup
      hitting a native HPFS regular file can get all data from directory
      entry) hpfs had a flag passed to that sucker.  Said flag had been
      protected by a semaphore lookalike made out of spit and duct-tape and
      callers of iget looked like
      
      	hpfs_lock_iget(sb, flag);
      	result = iget(sb, ino);
      	hpfs_unlock_iget(sb);
      
      Since now we are calling hpfs_read_inode() directly (note that calling
      it without hpfs_lock_iget() would simply break) we can forget all that
      crap and get rid of the flag - caller knows what it wants to call.
      
      BTW, that had killed one of the last sleep_on() users in fs/*/*.

      [PATCH] hpfs: new/read/write_inode() cleanups · eb3a6d15
      Alexander Viro authored
      	1) common initialization for all paths in hpfs_read_inode() taken into
      a separate helper (hpfs_init_inode())
      	2) hpfs mkdir(),create(),mknod() and symlink() do not bother with
      iget() anymore - they call new_inode(), do initializations and insert new
      inode into icache.  Handling of OOM failures cleaned up - if we can't
      allocate in-core inode, bail instead of corrupting the filesystem.
      Allocating in-core inode early also avoids one of the deadlocks here
      (hpfs_write_inode() from memory pressure by kmem_cache_alloc() could
      deadlock on attempt to lock our directory).
      	3) hpfs_write_inode() marks the inode dirty again in case if it
      fails to iget() its parent directory.  Again, OOM could trigger fs corruption
      here.

      [PATCH] hpfs: clean up lock ordering · fde48def
      Alexander Viro authored
      	hpfs_{lock,unlock}_{2,3}inodes() killed; all places that take more than
      one lock have ->i_sem held by VFS on all inodes involved and all hpfs per-inode
      locks are of the same type.  IOW, we can replace these guys with multiple
      hpfs_lock_inode() - order doesn't matter here.

      [PATCH] exportfs - Remove unnecessary locking from find_exported_dentry() · 1b8e3f21
      Andrew Morton authored
      From: "Jose R. Santos" <jrsantos@austin.ibm.com>
      
      After discussing it with Neil, he fell that the original justification for
      taking the kernel_lock on find_exported_dentry() is not longer valid and
      should be safe to remove.
      
      This patch fixes an issue while running SpecSFS where under memory
      pressure, shrinking dcache cause find_exported_dentry() to allocate
      disconnected dentries that later needed to be properly connected.  The
      connecting part of the code was done with BKL taken which cause a sharp
      drop in performance during iterations and profiles showing 75% time spent
      on find_exported_dentry().  After applying the patch, time spent on the
      function is reduce to <1%.
      
      I have tested this on an 8-way machine with 56 filesystems for several days
      now with no problems using ext2, ext3, xfs and jfs.

      [PATCH] ppc32: Fix booting some IBM PRePs · 6cfe07f4
      Andrew Morton authored
      From: Tom Rini <trini@kernel.crashing.org>
      
      The following patch comes from Paul Mackerras.  Earlier on in 2.6,
      arch/ppc/boot/utils/mkprep.c was changed slightly so that it would build
      and work on Solaris.  Doing this required changing from filling out
      pointers to an area to filling out a local copy of the struct.  However, a
      memcpy was left out, and the info is only needed on some machines to boot.
      The following adds in the missing memcpy and allows for IBM PRePs to boot
      from a raw floppy again.
