This patch series replaces the old non-generic Hardware Random Number
Generator support by a fully generic RNG API.
This makes it possible to register additional RNGs from modules. With this
patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG
available now.
Additionally two new RNG drivers are added for the "ixp4xx" and "omap"
devices. (Written by Deepak Saxena). This patch series includes the old
patches by Deepak Saxena.
The old x86-rng driver has beed split.
The userspace RNG daemon can later be updated to select the RNG through
/sys/class/misc/hw_random/ for convenience. For now it is sufficient to use
cat and echo -n on the sysfs attributes.

Add a /proc/<pid>/attr/keycreate entry that stores the appropriate context for
newly-created keys. Modify the selinux_key_alloc hook to make use of the new
entry. Update the flask headers to include a new "setkeycreate" permission
for processes. Update the flask headers to include a new "create" permission
for keys. Use the create permission to restrict which SIDs each task can
assign to newly-created keys. Add a new parameter to the security hook
"security_key_alloc" to indicate whether it is being invoked by the kernel, or
from userspace. If it is being invoked by the kernel, the security hook
should never fail. Update the documentation to reflect these changes.

Cause key_alloc_serial() to generate key serial numbers randomly rather than
in linear sequence.
Using an linear sequence permits a covert communication channel to be
established, in which one process can communicate with another by creating or
not creating new keys within a certain timeframe. The second process can
probe for the expected next key serial number and judge its existence by the
error returned.
This is a problem as the serial number namespace is globally shared between
all tasks, regardless of their context.
For more information on this topic, this old TCSEC guide is recommended:

Cause the keys linked to a keyring to be unlinked from it when revoked and it
causes the data attached to a user-defined key to be discarded when revoked.
This frees up most of the quota a key occupied at that point, rather than
waiting for the key to actually be destroyed.

Add the ability for key creation to overrun the user's quota in some
circumstances - notably when a session keyring is created and assigned to a
process that didn't previously have one.
This means it's still possible to log in, should PAM require the creation of a
new session keyring, and fix an overburdened key quota.

Magic sysrq fails to work on many keyboards, particulary most of notebook
keyboards. This patch fixes it.
The idea is quite simple: Discard the SysRq break code if Alt is still being
held down. This way the broken keyboard can send the break code (or the user
with a normal keyboard can release the SysRq key) and the kernel waits until
the next key is pressed or the Alt key is released.

nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on
model->num_counters (number of performance counters) being less than 10.
While this is currently the case, it's too clever by half.
Other archs aren't quite as clever: they assume 100. I suggest to
normalize them all to 1000.

dtl1_cs.c::dtl1_hci_send_frame()
There's a problem in drivers/bluetooth/dtl1_cs.c::dtl1_hci_send_frame()
If bt_skb_alloc() returns NULL, then skb_reserve(s, NSHL); will cause a
NULL pointer deref - ouch. If we can't allocate the resources we require
we need to tell the caller by returning -ENOMEM.

Here is a patch to the system call handling for 5307/5272/etc to:
- fix the strace support (one tested the wrong bit)
- make all system calls a little bit faster by inlining set_esp0 and
supporting ENOSYS out of the critical path.
- remove extraneous spaces

This patch solve a bug triggered by execvp (this function use calloc to
store the argument list and gcc 3.4.x align the stack to word, not to dword).
This situation aren't related to signal handling and all 2.6.x have the bug.
On ColdFire targets we must force the stack to be aligned.
