When we leave sigsuspend() directly into a signal handler, we don't want
to go via the normal syscall exit path -- it'll corrupt r4 and r5 which
are supposed to be giving information to the signal handler, and it'll
give us one more single-step SIGTRAP than we need if single-stepping is
in operation.

However, we _should_ be calling audit_syscall_exit(), which would
normally get invoked in that patch. It's not wonderfully pretty, but I
suspect the best answer is just to call it directly...

The following patch against audit.81 prevents duplicate syscall rules in
a given filter list by walking the list on each rule add.

I also removed the unused struct audit_entry in audit.c and made the
static inlines in auditsc.c consistent.

Paulus suggested that we put xLparMap in its own .c file so that we can
generate a .s file to be included into head.S.  This doesn't get around
the problem of having it at a fixed address, but it makes it more
palatable.

It would be good if this could be included in 2.6.13 as it solves our
build problems with various versions of binutils and gcc.  In
particular, it allows us to build an iSeries kernel on Debian unstable
using their biarch compiler.

This has been built and booted on iSeries and built for pSeries and g5.

Signed-off-by: Linus Torvalds <torvalds@osdl.org>

When the client performs an exclusive create and opens the file for writing,
a Netapp filer will first create the file using the mode 01777. It does this
since an NFSv3/v4 exclusive create cannot immediately set the mode bits.
The 01777 mode then gets put into the inode->i_mode. After the file creation
is successful, we then do a setattr to change the mode to the correct value
(as per the NFS spec).

The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so
the latter retains the 01777 mode. A bit later, the VFS notices this, and calls
remove_suid(). This of course now resets the file mode to inode->i_mode & 0777.
Hey presto, the file mode on the server is now magically changed to 0777. Duh...

Reported by: Pavel Kysilka (Bugzilla Bug 5059)

The intelfb driver does not keep resolution set with fbset after
switching to anot console and back.

Steps to reproduce:

  initial options: tty1,tty2 - 1024x768-60
  1) tty1 - fbset after booting (1024x768-60)
  2) tty1 - fbset 800x600-100
  tty1: 800x600-100
  3) swith to tty2, swith to tty1
  tty1: 1024x768-60 (the same resolution as default from kernel booting)

This bug is caused by intelfb unintentionally destroying info->flags in
set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify
fbcon of a mode change was cleared causing the above problem. This bug
though is not intelfb specific, as other drivers may also be affected.

The fix is to save info->flags in a local variable before calling any
of the driver hooks.  A more definitive fix (for post 2.6.13) is to
separate info->flags into one that is set by the driver and another that
is set by core fbdev/fbcon.

This adds a MOVE_SELF event to inotify.  It is sent whenever the inode
you are watching is moved.  We need this event so that we can catch
something like this:

 - app1:
	watch /etc/mtab

 - app2:
	cp /etc/mtab /tmp/mtab-work
	mv /etc/mtab /etc/mtab~
	mv /tmp/mtab-work /etc/mtab

app1 still thinks it's watching /etc/mtab but it's actually watching
/etc/mtab~.
