I tested it, and besides booting up fine, i also tested the 
get_random_int() randomness. I did this by adding this quick 
trace_printk() line:

   trace_printk("get_random_int(): %08x\n", get_random_int());

to sys_prctl() and triggered sys_prctl() in a loop, which gave a 
list of get_random_int() numbers:

# tracer: nop

           <...>-6303  [000]   618.163331: sys_prctl: get_random_int(): 093f5c70

Full list attached.

I then wrote a quick script to write those numbers out into a 
continous binary file (result also attached).

I then ran the FIPS randomness test over the first 20,000 bits [2.5K 
data], which it passed:

rngtest: bits received from input: 20064
rngtest: bits sent to output: 20000
rngtest: FIPS 140-2 successes: 1
rngtest: FIPS 140-2 failures: 0
rngtest: FIPS 140-2(2001-10-10) Monobit: 0
rngtest: FIPS 140-2(2001-10-10) Poker: 0
rngtest: FIPS 140-2(2001-10-10) Runs: 0
rngtest: FIPS 140-2(2001-10-10) Long run: 0
rngtest: FIPS 140-2(2001-10-10) Continuous run: 0
rngtest: input channel speed: (min=3.104; avg=3.104; max=3.104)Gibits/s
rngtest: FIPS tests speed: (min=110.892; avg=110.892; max=110.892)Mibits/s
rngtest: output channel speed: (min=544.957; avg=544.957; max=544.957)Mibits/s
rngtest: Program run time: 294 microseconds

So it looks good enough - that's a sample of 800+ pseudo-random 
integers.

I also modified your patch to include two more random sources, 
get_cycles() [which all 22 architectures define - albeit not all 
have the hw to actually do fine-grained cycle counts - so for some 
it's always-zero or a low-res return value], plus a kernel stack 
address.

The relevant line is:

+	hash[0] += current->pid + jiffies + get_cycles() + (int)(long)&ret;

The argument is that the more layers we have here, the harder it 
becomes to _reliably_ attack a given system. Works-100%-sure is an 
important prize for certain types of attackers - and with the cycle 
counter, jiffies, PID and a kernel address all mixed in that becomes 
quite hard to achieve.

I tested this too - it also results in good random numbers. Find the 
patch below.

Subject: random: make get_random_int() more random
From: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>
Date: Tue, 5 May 2009 08:17:43 -0700 (PDT)

It's a really simple patch that basically just open-codes the current
"secure_ip_id()" call, but when open-coding it we now use a _static_
hashing area, so that it gets updated every time.

And to make sure somebody can't just start from the same original seed of
all-zeroes, and then do the "half_md4_transform()" over and over until
they get the same sequence as the kernel has, each iteration also mixes in
the same old "current->pid + jiffies" we used - so we should now have a
regular strong pseudo-number generator, but we also have one that doesn't
have a single seed.

Note: the "pid + jiffies" is just meant to be a tiny tiny bit of noise. It
has no real meaning. It could be anything. I just picked the previous
seed, it's just that now we keep the state in between calls and that will
feed into the next result, and that should make all the difference.

I made that hash be a per-cpu data just to avoid cache-line ping-pong:
having multiple CPU's write to the same data would be fine for randomness,
and add yet another layer of chaos to it, but since get_random_int() is
supposed to be a fast interface I did it that way instead. I considered
using "__raw_get_cpu_var()" to avoid any preemption overhead while still
getting the hash be _mostly_ ping-pong free, but in the end good taste won
out.
