sk98line tries to register a procfile with the interfacename of the struct
net_device.  The patch below (ontop of the previous one) makes it work
unless you change the interface name manually, but as Linux explicitly
allows that the interface is fundamentally broken and probably should just
go away.

If tty_open() fails for a normal serial device, we end up doing cleanups
that should only happen for failed open of /dev/ptmx.  The results are
not pretty - devpts et.al.  end up very confused.  That's what gave
problems with ptmx.

This splits ptmx file_operations from the normal case and cleans up both
tty_open() and (new) ptmx_open().  Survived serious beating.

Update architectures for the free_area_init_node() API change.

The patch below fixes an interesting oddity we're seeing with fedora core
development (where we recently started using udev heavily); basically right
now filelock_init() is a module_init(), eg runs late.  However that breaks
down because there are earlier /sbin/hotplug callouts, which with udev, do
locking operations.  When that happens the kernel oopses because the slabs
for file locks aren't initialized yet.

Solution: initialize this way early.  It's only a kmem_cache_create after
all, so can happen early.

ncfpfs seems to update inode times by hand everywhere instead of using
the proper helpers.  This means:

 - the atime updates in mmap() and read() seems to miss various checks
   upodate_atime or one of the wrappers does.  Also it doesn't mark the
   inode dirty.
 - in write() you update mtime and _a_time instead of ctime as expected,
   also the usual checks and optimizations are missing.

In addition the fops contain some bogus checks like for a refular file (but
the fops are only used of ISREG files) and inode->i_sb although that is
guranteed to be non-zero.

Recently, someone has kvetched that RNDGETPOOL is a "security
vulnerability".  Never mind that it is superuser only, and with superuser
privs you could load a nasty kernel module, or read the entropy pool out of
/dev/mem directly, but they are nevertheless still spreading FUD.

In any case, no one is using it (it was there for debugging purposes only),
so we can remove it as dead code.

This patch adds a separate pool for use with /dev/urandom.  This prevents a
/dev/urandom read from being able to completely drain the entropy in the
/dev/random pool, and also makes it much more difficult for an attacker to
carry out a state extension attack.

This adds a pool name to the entropy_store data structure, which simplifies

There's two callers:

 - the truncate path via notify_change, ->setattr, vmtruncate.  We
   already check for permissions here at the upper level
 - fat_delete_inode.  This one looks bogus to me - even if we delete
   an read-only or immutable inode we want to free the space allocated
   by it, else you leak disk blocks.

We received a bug report that /proc/PID/cmdline only shows argv[0] if the
total length of all arguments exceeds PAGE_SIZE.  The problem is that
proc_pid_cmdline checks for the presence of a NUL byte at the end of the
args list, and assumes that the application did a setproctitle if there's
any other character.

OTOH proc_pid_cmdline will read just the first PAGE_SIZE worth of arguments
at most, and if you have more arguments, it's quite likely that there won't
be a NUL byte at offset PAGE_SIZE-1.

The attached patch fixes this.

  When using bounce buffers for SG_IO commands with unaligned buffers in
  blk_rq_map_user(), we should free the pages from blk_rq_unmap_user() which
  calls bio_uncopy_user() for the non-BIO_USER_MAPPED case.  That function
  failed to free the pages for write requests.

  So we leaked pages and you machine would go OOM.  Rebooting helped ;-)

  This bug was triggered by writing audio CDs (but not on data CDs), as the
  audio frames are not aligned well (2352 bytes), so the user pages don't just
  get mapped.

  Bug was reported by Mathias Homan and debugged by Chris Mason + me.  (Jens
  is away.)
