When we are not the real parent of the dst (e.g., when we're xfrm_dst and
the child is an rtentry), it may already be on the GC list.

In fact the current code is buggy to, we need to check dst->flags before
the dec as dst may no longer be valid afterwards.

This recently got changed to include a lot of kernel internal stuff in the
non-__KERNEL__ area of the header, which isn't so kosher and breaks libc
builds.

The fix is pretty simple.

Working on some code lately I've been getting huge values for "Cached".
The cause is that get_page_cache_size() is an approximate value, and for a
sufficiently small returned value of get_page_cache_size() the value
underflows.

We will return NULL from filemap_getpage when a page does not exist in the
page cache and MAP_NONBLOCK is specified, here:

	page = find_get_page(mapping, pgoff);
	if (!page) {
		if (nonblock)
			return NULL;
		goto no_cached_page;
	}

But we forget to do so when the page in the cache is not uptodate.  The
following could result in a blocking call:

	/*
	 * Ok, found a page in the page cache, now we need to check
	 * that it's up-to-date.
	 */
	if (!PageUptodate(page))
		goto page_not_uptodate;

This patch fixes a bug in the SELinux Netlink message type detection code,
where the wrong constant was being used in a case statement.  The incorrect
value is not valid for this class of object so it would not have been
reached, and fallen through to a default handler for all Netlink messages.

Fix the access-above-bottom-of-stack crash.

1. Allows to preserve the valueable optimization

2. Works for NMIs

3.  Doesn't care whether or not there are more of the like instances
   where the stack is left empty.

4. Seems to work for me without the crashes:)

This was unexported by Arjan because we have no current users.

However, during a conversion from tasklets to workqueues of the parisc led
functions, we ran across a case where this was needed.  In particular, the
open coded equivalent of cancel_rearming_delayed_workqueue was implemented
incorrectly, which is, I think, all the evidence necessary that this is a
useful API.

In the deflate_[compress|uncompress|pcompress] functions we call the
zlib_[in|de]flateReset function at the beginning.  This is OK.  But when we
unload the deflate module we don't call zlib_[in|de]flateEnd to free all
the zlib internal data.  It looks like a bug for me.  Please, consider the
attached patch.

ARM wasn't raising a SIGBUS with a siginfo structure.  Fix
__do_user_fault() to allow us to use it for SIGBUS conditions, and arrange
for the sigbus path to use this.

We need to prevent the siginfo code being called if we do not have a user
space context to call it, so consolidate the "user_mode()" tests.

Thanks to Ian Campbell who spotted this oversight.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
