Only root or processes with gid AID_NET_BT or AID_NET_BT_ADMIN
can create RFCOMM, SCO and L2CAP sockets.

Only root or process with gid AID_NET_BT_ADMIN can open other
AF_BLUETOOTH sockets (for example HCI).

This required introducing android_aid.h with the hardcoded
android id's.

filemap_fault will go into an infinite loop if ->readpage() fails
asynchronously.

AFAICS the bug was introduced by this commit, which removed the wait after the
final readpage:

       mm: fix fault vs invalidate race for linear mappings

Fix by reintroducing the wait_on_page_locked() after ->readpage() to make sure
the page is up-to-date before jumping back to the beginning of the function.

I've noticed this while testing nfs exporting on fuse.  The patch
fixes it.

If schedule was interrupted in the idle thread by an
interrupt that did not cause another reschedule, the tick
would be stopped. Another interrupt could then cause a
reschedule without restarting the tick.

Introduce a new socket ioctl, SIOCKILLADDR, that nukes all sockets
bound to the same local address. This is useful in situations with
dynamic IPs, to kill stuck connections.

This fixes a race if another thread acquired the console
while it was suspended and released it after it was resumed
the secondary console semaphre would be left locked, and the
primary semaphore would be released twice. This in turn caused
the console switch on suspend or resume to hang forever.

Note that suspend_console does not actually lock the console
for clients that use acquire_console_sem, it only locks it for
clients that use try_acquire_console_sem. If we change
suspend_console to fully lock the console, then the kernel
may deadlock on suspend.

The ashmem subsystem is a new shared memory allocator, similar
to POSIX SHM but with different behavior and sporting a simpler
file-based API.  It also provides a mechanism for marking memory
that may be revoked by the kernel under low memory conditions
(pin/unpin).

Up to six levels are supported. By default processes
with a oomkilladj value of 0 or higer are killed if
the sum if the page cache is less than 6MB when we
run out of memory, 1 or higher if it is less than 8MB,
6 or higher if it less than 16MB and 12 or higher if
it is less than 16MB.
