Add a gfp_mask to audit_log_start() and audit_log(), to reduce the
amount of GFP_ATOMIC allocation -- most of it doesn't need to be
GFP_ATOMIC. Also if the mask includes __GFP_WAIT, then wait up to
60 seconds for the auditd backlog to clear instead of immediately
abandoning the message.
The timeout should probably be made configurable, but for now it'll
suffice that it only happens if auditd is actually running.

If we have enough rules to fill the netlink buffer space, it'll
deadlock because auditctl isn't ever actually going to read from the
socket until we return, and we aren't going to return until it
reads... so we spawn a kernel thread to spew out the list and then
exit.

When LOOKUP_PARENT is used, the inode which results is not the inode
found at the pathname. Report the flags so that this doesn't generate

Turn the field from a bitmask to an enumeration and add a list to allow
filtering of messages generated by userspace. We also define a list for
file system watches in anticipation of that feature.

This patch changes the type of the third parameter 'length' of the
raw_send_hdrinc() function from 'int' to 'size_t'.
This makes sense since this function is only ever called from one
location, and the value passed as the third parameter in that location is
itself of type size_t, so this makes the recieving functions parameter
type match. Also, inside raw_send_hdrinc() the 'length' variable is
used in comparisons with unsigned values and passed as parameter to
functions expecting unsigned values (it's used in a single comparison with
a signed value, but that one can never actually be negative so the patch
also casts that one to size_t to stop gcc worrying, and it is passed in a
single instance to memcpy_fromiovecend() which expects a signed int, but
as far as I can see that's not a problem since the value of 'length'
shouldn't ever exceed the value of a signed int).

This patch changes the type of the local variable 'i' in
raw_probe_proto_opt() from 'int' to 'unsigned int'. The only use of 'i' in
this function is as a counter in a for() loop and subsequent index into
the msg->msg_iov[] array.
Since 'i' is compared in a loop to the unsigned variable msg->msg_iovlen
gcc -W generates this warning :
net/ipv4/raw.c:340: warning: comparison between signed and unsigned
Changing 'i' to unsigned silences this warning and is safe since the array
index can never be negative anyway, so unsigned int is the logical type to
use for 'i' and also enables a larger msg_iov[] array (but I don't know if
that will ever matter).

This patch gets rid of the following gcc -W warning in net/ipv4/raw.c :
net/ipv4/raw.c:387: warning: comparison of unsigned expression < 0 is always false
Since 'len' is of type size_t it is unsigned and can thus never be <0, and
since this is obvious from the function declaration just a few lines above
I think it's ok to remove the pointless check for len<0.

This patch silences these two gcc -W warnings in net/ipv4/raw.c :
net/ipv4/raw.c:517: warning: signed and unsigned type in conditional expression
net/ipv4/raw.c:613: warning: signed and unsigned type in conditional expression
It doesn't change the behaviour of the code, simply writes the conditional
expression with plain 'if()' syntax instead of '? :' , but since this
breaks it into sepperate statements gcc no longer complains about having
both a signed and unsigned value in the same conditional expression.

The simplicity of the fifo qdisc allows several qdisc operations to be
redirected to the relevant queue management function directly. Saves
