timekeeping: Fix time moving backwards

Changed the calculation logic that sometimes calculates
the time wrong.

Sometimes there is an overflow when the tv_nsec field in
the timespec structure is being added since it is 32-bit.

To resolve this issue nsec variable is being added first
so that the addition is performed in 64 bit signed format.

SELinux: include definition of new capabilities

The kernel has added CAP_WAKE_ALARM and CAP_EPOLLWAKEUP.  We need to
define these in SELinux so they can be mediated by policy.

CHROMIUM: mm: Fix calculation of dirtyable memory

The system uses global_dirtyable_memory() to calculate
number of dirtyable pages/pages that can be allocated
to the page cache.  A bug causes an underflow thus making
the page count look like a big unsigned number.  This in turn
confuses the dirty writeback throttling to aggressively write
back pages as they become dirty (usually 1 page at a time).

Fix is to ensure there is no underflow while doing the math.

android: binder: Add security hooks to binder and implement the hooks for SELinux.

Add security hooks to the binder and implement the hooks for SELinux.
The security hooks enable security modules such as SELinux to implement
controls over binder IPC.  The security hooks include support for
controlling what process can become the binder context manager
(binder_set_context_mgr), controlling the ability of a process
to invoke a binder transaction/IPC to another process (binder_transaction),
controlling the ability a process to transfer a binder reference to
another process (binder_transfer_binder), and controlling the ability
of a process to transfer an open file to another process (binder_transfer_file).

This support is used by SE Android, http://selinuxproject.org/page/SEAndroid.
