[PATCH] Eicon driver: add missing uaccess
This patch adds asm/uaccess.h to files which uses copy_to/from_user()

This fixes a bug where attempting to remove the viocd module when no
virtual cdroms where actually present would cause an oops. The driver
was not completing its initialisation in this case.

[PATCH] amd64 compat annotations
* new helper - ptr_to_compat(); inverse to compat_ptr(), with proper
typechecking. A lot of open-coded equivalents replaced with using
that one.
* a couple of severely misguiding places got back to sanity - we had
basically
put_user((long)p, &foo->compat_uptr_t_field);
That will, of course, cast (long)p further - to u32, but that fact is
carefully obfuscated... Sanitized by replacing (long)p in such places
with ptr_to_compat(p); fortunately, there hadn't been many of those...

[PATCH] openpromfs property_read() fix
openpromfs property_read() is slightly abused by property_write() - the
latter calls property_read(file, NULL, 0, NULL) if we still hadn't done
any IO on that file; property_read() will do setup work and, since it's
called with count equal to 0, do nothing else.
That stopped working - now we check if *ppos is sane before doing
anything else and that, of course, oopses. Trivial fix is to move the
check past that for count == 0...

[PATCH] sched: fix preemption race (Core/i386)
The idle-thread-preemption-fix.patch introduced a race, which is not
critical, but might give us an extra turn through the scheduler. When
interrupts are reenabled in entry.c and an interrupt occures before we
reach the add_preempt_schedule() in preempt_schedule we get rescheduled
again in the return from interrupt path.
The patch prevents this by leaving interrupts disabled and calling a a
seperate function preempt_schedule_irq().
This split adds different plausibility checks for irq context calls and
kernel calls.

Yes, me too. generic_shutdown_super() takes lock_super(). And udf uses
lock_super for protecting its block allocation data strutures. Trivial
deadlock on unmount.
Below is a fix to switch udf to it's own private locking. It's safe
because it doesn't intefere with VFS lock_super usage anywhere.
udf_free_inode has some more updates than simply switching the used
lock:
- clear_inode() call moved outside locked section to avoid another
deadlock
- unused variable ino killed
- is_directory moved into the conditional it's actually used in

[PATCH] audit: handle loginuid through proc
The audit subsystem uses netlink messages to request loginuid changes. Due
to the sensitivity of loginuid, netlink appears to be insufficient. For
instance, it is not easy to guarantee that the loginuid message will be
handled before any other auditable actions, and there is even the remote
possibility of the process terminating and another process with the same
pid being created before the message is handled. Finally, other kernel
code, in particular selinux, is interested in easily querying the loginuid
for inclusion in its own messages.
The following patch moves loginuid handling from netlink to the
/proc/$$/loginuid file, and adds a audit_get_loginuid() function. It also
includes Stephen Smalley's patch to correctly inherit the loginuid on fork.
It has been actively discussed on the linux-audit mailing list.
