Graceful failure instead of panicking in kmem_malloc

For logging procedure, I am hoping that by keeping some memory aside, I
should be able to guarantee that the procedure will not run out of memory.
For shutdown, I don't know. I am not sure if doing the usual shutdown is
even required.
To me this appears to be a generic requirement of any system i.e.
a) Set aside some memory to handle out of memory conditions. Establish a low
threshold
b) When the system reaches the low threshold,
   1) stop all processing (not sure right  now if this translates to
shutdown)
   2) record the error.

Thanks for sending the patch. The patch essentially will try to reclaim
memory 8 times before panicking. Is the understanding correct? If so, how
did you arrive at the number 8?
