Staging: android: binder: Fix memory leak on thread/process exit

If a thread or process exited while a reply, one-way transaction or

was leaked.

Staging: android: binder: Allow using highmem for binder buffers

The default kernel mapping for the pages allocated for the binder
buffers is never used. Set the __GFP_HIGHMEM flag when allocating
these pages so we don't needlessly use low memory pages that may
be required elsewhere.

staging: android: Fix two checkpatch issues in binder.c

This fixes two instances of
"static const char * array should probably be static const char * const"

I have seen other commits doing this in other files, so I am
assuming it should be done here as well.

Please tell me if this is wrong :)

staging: android: Avoid using camelcase in binder.h

This changes the following:

1: BinderDriverReturnProtocol -> binder_driver_return_protocol
2: BinderDriverCommandProtocol -> binder_driver_return_protocol

These enums are not currently used, but still generate noise in checkpatch.

Well, did. They don't now :)

tmpfs: fix mempolicy object leaks

This patch fixes several mempolicy leaks in the tmpfs mount logic.
These leaks are slow - on the order of one object leaked per mount
attempt.

Leak 1 (umount doesn't free mpol allocated in mount):
    while true; do
        mount -t tmpfs -o mpol=interleave,size=100M nodev /mnt
        umount /mnt
    done

Leak 2 (errors parsing remount options will leak mpol):
    mount -t tmpfs -o size=100M nodev /mnt
    while true; do
        mount -o remount,mpol=interleave,size=x /mnt 2> /dev/null
    done
    umount /mnt

Leak 3 (multiple mpol per mount leak mpol):
    while true; do
        mount -t tmpfs -o mpol=interleave,mpol=interleave,size=100M nodev /mnt
        umount /mnt
    done

This patch fixes all of the above.  I could have broken the patch into
three pieces but is seemed easier to review as one.

signal: Define __ARCH_HAS_SA_RESTORER so we know whether to clear sa_restorer

Vaguely based on upstream commit 574c4866e33d 'consolidate kernel-side
struct sigaction declarations'.

flush_signal_handlers() needs to know whether sigaction::sa_restorer
is defined, not whether SA_RESTORER is defined.  Define the
__ARCH_HAS_SA_RESTORER macro to indicate this.

SUNRPC: Add barriers to ensure read ordering in rpc_wake_up_task_queue_locked

commit 1166fde6a923c30f4351515b6a9a1efc513e7d00 upstream.

We need to be careful when testing task->tk_waitqueue in
rpc_wake_up_task_queue_locked, because it can be changed while we
are holding the queue->lock.
By adding appropriate memory barriers, we can ensure that it is safe to
test task->tk_waitqueue for equality if the RPC_TASK_QUEUED bit is set.

Bluetooth: Fix not closing SCO sockets in the BT_CONNECT2 state

commit eb20ff9c91ddcb2d55c1849a87d3db85af5e88a9 upstream.

With deferred setup for SCO, it is possible that userspace closes the
socket when it is in the BT_CONNECT2 state, after the Connect Request is
received but before the Accept Synchonous Connection is sent.

If this happens the following crash was observed, when the connection is
terminated:

staging: comedi: s626: fix continuous acquisition

commit e4317ce877a31dbb9d96375391c1c4ad2210d637 upstream.

For the s626 driver, there is a bug in the handling of asynchronous
commands on the AI subdevice when the stop source is `TRIG_NONE`.  The
command should run continuously until cancelled, but the interrupt
handler stops the command running after the first scan.

The command set-up function `s626_ai_cmd()` contains this code:

	switch (cmd->stop_src) {
	case TRIG_COUNT:
		/*  data arrives as one packet */
		devpriv->ai_sample_count = cmd->stop_arg;
		devpriv->ai_continous = 0;
		break;
	case TRIG_NONE:
		/*  continous acquisition */
		devpriv->ai_continous = 1;
		devpriv->ai_sample_count = 0;
		break;
	}

The interrupt handler `s626_irq_handler()` contains this code:

		if (!(devpriv->ai_continous))
			devpriv->ai_sample_count--;
		if (devpriv->ai_sample_count <= 0) {
			devpriv->ai_cmd_running = 0;
			/* ... */
		}

So `devpriv->ai_sample_count` is only decremented for the `TRIG_COUNT`
case, but `devpriv->ai_cmd_running` is set to 0 (and the command
stopped) regardless.

Fix this in `s626_ai_cmd()` by setting `devpriv->ai_sample_count = 1`
for the `TRIG_NONE` case.  The interrupt handler will not decrement it
so it will remain greater than 0 and the check for stopping the
acquisition will fail.
