18dabf473e Change table chaining layout
Change the page member of the scatterlist structure to be an unsigned
long, and encode more stuff in the lower bits:

- Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located
  at sg + 1.
- Bit 0 set: this is a chain entry, the next real entry is at ->page_link
  with the two low bits masked off.
- Bit 1 set: this is the final entry in the sg entry. sg_next() will return
  NULL when passed such an entry.

It's thus important that sg table users use the proper accessors to get
and set the page member.

This path mustn't have been tested :( I did attempt to exercise it
by injecting failures here, but I suspect PageMappedToDisk may have
been getting in the way. Will need more of a look, although I think
nobh mode is OK for an -rc1 (it shouldn't eat anyone's data).

74c3cbe33b [PATCH] audit: watching subtrees
New kind of audit rule predicates: "object is visible in given subtree".
The part that can be sanely implemented, that is.  Limitations:
	* if you have hardlink from outside of tree, you'd better watch
it too (or just watch the object itself, obviously)
	* if you mount something under a watched tree, tell audit
that new chunk should be added to watched subtrees
	* if you umount something in a watched tree and it's still mounted
elsewhere, you will get matches on events happening there.  New command
tells audit to recalculate the trees, trimming such sources of false
positives.

Note that it's _not_ about path - if something mounted in several places
(multiple mount, bindings, different namespaces, etc.), the match does
_not_ depend on which one we are using for access.

7210c67820 [PARISC] fix uninitialized variable warning in asm/rtc.h
get_rtc_time, in the case that PDC returns that the battery is bad, returns
an unmodified rtc_time arg to the caller, which then uses uninitialized
values. Fix this by memset-ing the arg with zeroes, so it will at least be
cleared if we return failure.

e8b8c97773 Revert "kconfig: tristate choices with mixed tristate and boolean values"
This reverts commit a5bf3d891a.

David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:

  "That Kconfig hasn't changed (other than adding new drivers), and it's
   worked that way for several years now ...  so the issue seems to be
   changes in menuconfig/kconfig/etc semantics.

   The issue is that when USB_GADGET=m, it's no longer possible to
   configure peripheral controller drivers as modules ...  the
   controller drivers can now only be configured for static linkage.

   It should be making a choice of one of the controller drivers which
   could work on the target system, and allow that driver to be linked
   either as a module (ok iff USB_GADGET=m) or statically."

Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.
