Random number generator initialization cleanup:
- Introduce new SI_SUB_RANDOM point in boot sequence to make it

early as possible, so place it just after SI_SUB_CPU where we
have some randomness on most platforms via get_cyclecount().
- Move stack protector initialization to be after SI_SUB_RANDOM

stack protector to actually protect stack with some random guard
value instead of a well-known one.
Note that this patch doesn't try to address arc4random(9) issues.
With current code, it will be implicitly seeded by stack protector

Close a race with caching of -ve name lookups in the NFS client.
Specifically, clients only trust -ve cache entries while the directory
remains unchanged and discard any -ve cache entries for a directory when
they notice that the modification time of a directory entry changes. The
race involves two concurrent lookups as follows:
- Thread A does a lookup for file 'foo' which sends a lookup RPC to the
server. The lookup fails and the server replies.
- The 'foo' file is created (either by the same client or a different
client) updating the modification time on the parent directory of 'foo'.
- Thread B does a lookup for a different file 'bar' which updates the
cached attributes of the parent directory of 'foo' to reflect the new
modification time after 'foo' was created.
- Thread A finally resumes execution to parse the reply from the NFS
server. It adds a -ve cache entry and sets the cached value of the
directory's modification time that is used for invalidating -ve cached
lookups to the new modification time set by thread B.
At this point, future lookups of 'foo' will honor the -ve cached entry
until the cached entry is pushed out of the name cache's LRU or the
modification time of the parent directory is changed again by some other
change. The fix is to read the directory's modification time before
sending the lookup RPC and use that cached modification time when setting
the directory's cached modification time. Also, we do not add a -ve cache
entry if another thread has added -ve cache entry that set the directory's
cached modification time to a newer value than the value we read before
sending the lookup RPC.

such, a new entry is created each time arpresolve() is called.
