34bb61f9dd [PATCH] fix klist semantics for lists which have elements removed on traversal
The problem is that klists claim to provide semantics for safe traversal of
lists which are being modified.  The failure case is when traversal of a
list causes element removal (a fairly common case).  The issue is that
although the list node is refcounted, if it is embedded in an object (which
is universally the case), then the object will be freed regardless of the
klist refcount leading to slab corruption because the klist iterator refers
to the prior element to get the next.

The solution is to make the klist take and release references to the
embedding object meaning that the embedding object won't be released until
the list relinquishes the reference to it.

(akpm: fast-track this because it's needed for the 2.6.13 scsi merge)

a08b6b7968 [PATCH] Kconfig fix (BLK_DEV_FD dependencies)
Sanitized and fixed floppy dependencies: split the messy dependencies for
BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making

BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h
are *not* going to have floppy.c compile, let alone work).

If you can come up with better name for that ("this architecture might
have working PC-compatible floppy disk controller"), you are more than

dc9ca2af49 [PATCH] DVB: lgdt330x check callback fix
Most of the patch is whitespace cleanup, but more importantly, this patch
checks to see whether a callback is set before calling it.  On cx88 boards
(currently the only boards using lgdt330x in 2.6.13) every callback is set.
However, newer drivers currently in development leave a callback undefined,
and lgdt330x must not call it if it isn't defined.

0bb6fcc13a [PATCH] pivot_root() circular reference fix
Fix http://bugzilla.kernel.org/show_bug.cgi?id=4857

When pivot_root is called from an init script in an initramfs environment,
it causes a circular reference in the mount tree.

The cause of this is that pivot_root() is not prepared to handle pivoting
an unattached mount.  In an initramfs environment, rootfs is the root of
the namespace, and so it is not attached.

This patch fixes this and related problems, by returning -EINVAL if either
the current root or the new root is detached.

The fix has been stress tested on i386, ia64, pp64 and on x86_64.  To
reproduce the problem insert kprobes on schedule() and do_IRQ() functions
and you should see hang or system crash.

bce0649417 [PATCH] kprobes: fix handling of simultaneous probe hit/unregister
This patch fixes a bug in kprobes's handling of a corner case on i386 and
x86_64.  On an SMP system, if one CPU unregisters a kprobe just after
another CPU hits that probepoint, kprobe_handler() on the latter CPU sees
that the kprobe has been unregistered, and attempts to let the CPU continue
as if the probepoint hadn't been hit.  The bug is that on i386 and x86_64,
we were neglecting to set the IP back to the beginning of the probed
instruction.  This could cause an oops or crash.

This bug doesn't exist on ppc64 and ia64, where a breakpoint instruction
leaves the IP pointing to the beginning of the instruction.  I don't know
about sparc64.  (Dave, could you please advise?)

This fix has been tested on i386 and x86_64 SMP systems.  To reproduce the
problem, set one CPU to work registering and unregistering a kprobe
repeatedly, and another CPU pounding the probepoint in a tight loop.

661e5a3d99 [PATCH] Kprobes/IA64: fix race when break hits and kprobe not found
This patch addresses a potential race condition for a case where Kprobe has
been removed right after another CPU has taken a break hit.

The way this is addressed here is when the CPU that has taken a break hit
does not find its corresponding kprobe, then we check to see if the
original instruction got replaced with other than break.  If it got
replaced with other than break instruction, then we continue to execute
from the replaced instruction, else if we find that it is still a break,
then we let the kernel handle this, as this might be the break instruction
inserted by other than kprobe(may be kernel debugger).

d0aaff9796 [PATCH] Kprobes: prevent possible race conditions generic
There are possible race conditions if probes are placed on routines within the
kprobes files and routines used by the kprobes.  For example if you put probe
on get_kprobe() routines, the system can hang while inserting probes on any
routine such as do_fork().  Because while inserting probes on do_fork(),
register_kprobes() routine grabs the kprobes spin lock and executes
get_kprobe() routine and to handle probe of get_kprobe(), kprobes_handler()
gets executed and tries to grab kprobes spin lock, and spins forever.  This
patch avoids such possible race conditions by preventing probes on routines
within the kprobes file and routines used by kprobes.

I have modified the patches as per Andi Kleen's suggestion to move kprobes
routines and other routines used by kprobes to a seperate section
.kprobes.text.

Also moved page fault and exception handlers, general protection fault to
.kprobes.text section.

These patches have been tested on i386, x86_64 and ppc64 architectures, also
compiled on ia64 and sparc64 architectures.

don't see the point of setting it to 0 in the "else" case.  >From what I
see in 2.6.12 it should probably be set to -ENODEV at the begining of the
"else" case.  The attached patch does this.

Note that I didn't actually see any breakage caused by this.
