char: moxa, prevent opening unavailable ports

In moxa.c there are 32 minor numbers reserved for each device.  The number
of ports actually available per device is stored in
moxa_board_conf->numPorts.  This number is not considered in moxa_open().
Opening a port that is not available results in a kernel oops.  This patch
adds a test to moxa_open() that prevents opening unavailable ports.

ptrace: wait_task_zombie: do not account traced sub-threads

The bug is ancient.

If we trace the sub-thread of our natural child and this sub-thread exits,
we update parent->signal->cxxx fields. But we should not do this until
the whole thread-group exits, otherwise we account this thread (and all
other live threads) twice.

Add the task_detached() check. No need to check thread_group_empty(),
wait_consider_task()->delay_group_leader() already did this.

spi_mpc83xx: split mpc83xx_spi_work() into two routines

mpc83xx_spi_work() is quite large, with up to five indentation levels and
is quite difficult to read.

So, split the function in two parts:
1. mpc83xx_spi_work() now only traverse queued spi messages;
2. mpc83xx_spi_do_one_msg() only manages single messages.

There should be no functional changes.

spi_mpc83xx: quieten down the "Requested speed is too low" message

When a platform is running at high frequencies it's not always possible to
scale-down a frequency to a requested value, and using mmc_spi driver this
leads to the following printk flood during card polling:

  ...
  mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use
  520828 Hz instead.
  mmc_spi spi32766.0: Requested speed is too low: 400000 Hz. Will use
  520828 Hz instead.
  ...

Fix this by using WARN_ONCE(), it's better than the flood, and also better
than turning dev_err() into dev_dbg(), since we actually want to warn that
some things may not work correctly.

Staging: heci: fix setting h_is bit in h_csr register

Host software could issue interrupts to ME firmware, using H_IG bit. While
Setting H_IG bit, host software should preserve all the other bits in H_CSR
unchanged. In the original function which sets H_CSR register, they first read
the register, then set some bits, and write the whole 32bits back to the
register. And that the special behavior of H_IS (write-one-to-zero) causes problem.
This patch fixes the issue in the following ways:

- Modify heci_set_csr_register() function so that it doesn't change H_IS bit.
- Add interface heci_csr_clear_his() to clear H_IS bit. This function is called
   after H_IS checking (dev->host_hw_state & H_IS == H_IS).
- In original heci_csr_disable_interrupts() function, it not only clears H_IE
   bit, sometimes it also clears H_IS bit. This patch separates the two parts.
- Avoid calling write_heci_register() function to set H_CSR register directly,
   and instead using heci_set_csr_register() function

staging: p9auth: prevent some oopses and memory leaks

Before all testcases, do:
mknod /dev/caphash c 253 0
mknod /dev/capuse c 253 1

This patch does the following:

1. caphash write of > CAP_NODE_SIZE bytes overruns node_ptr->data
(test: cat /etc/mime.types > /dev/caphash)
2. make sure we don't dereference a NULL cap_devices[0].head
(test: cat serge@root@abab > /dev/capuse)
3. don't let strlen dereference a NULL target_user etc
(test: echo ab > /dev/capuse)
4. Don't leak a bunch of memory in cap_write().  Note that
   technically node_ptr is not needed for the capuse write case.
   As a result I have a much more extensive patch splitting up
   cap_write(), but I thought a smaller patch that is easier to test
   and verify would be a better start.  To test:
cnt=0
while [ 1 ]; do
echo /etc/mime.types > /dev/capuse
if [ $((cnt%25)) -eq 0 ]; then
head -2 /proc/meminfo
fi
cnt=$((cnt+1))
sleep 0.3
done
   Without this patch, it MemFree steadily drops.  With the patch,
   it does not.

I have *not* tested this driver (with or without these patches)
with factotum or anything - only using the tests described above.
