[WATCHDOG] OMAP fixes: enable clock in probe, trigger timer reload

This patch contains two fixes:

1)In omap_wdt_probe() the watchdog is reset and disabled. This
requires register access and the clks needs to be enabled temporarily

2)In omap_wdt_open() the timer register needs to be reloaded
to trigger a new timer value (the default of 60s)

Tested on OMAP34xx platform (Zoom1)

[WATCHDOG] add bcm47xx watchdog driver

This add watchdog driver for broadcom 47xx device.
It uses the ssb subsytem to access embeded watchdog device.

Because the watchdog timeout is very short (about 2s), a soft timer is used
to increase the watchdog period.

Note : A patch for exporting the ssb_watchdog_timer_set will
be submitted on next linux-mips merge. Without this patch it can't
be build as a module.

x86: don't use 'access_ok()' as a range check in get_user_pages_fast()

It's really not right to use 'access_ok()', since that is meant for the
normal "get_user()" and "copy_from/to_user()" accesses, which are done
through the TLB, rather than through the page tables.

Why? access_ok() does both too few, and too many checks.  Too many,
because it is meant for regular kernel accesses that will not honor the
'user' bit in the page tables, and because it honors the USER_DS vs
KERNEL_DS distinction that we shouldn't care about in GUP.  And too few,
because it doesn't do the 'canonical' check on the address on x86-64,
since the TLB will do that for us.

So instead of using a function that isn't meant for this, and does
something else and much more complicated, just do the real rules: we
don't want the range to overflow, and on x86-64, we want it to be a
canonical low address (on 32-bit, all addresses are canonical).

ide-cd: prevent null pointer deref via cdrom_newpc_intr

With 2.6.30, the error handling code in cdrom_newpc_intr was changed
to deal with partial request failures by normally completing the 'good'
parts of a request and only 'error' the last (and presumably,
incompletely transferred) bio associated with a particular
request. In order to do this, ide_complete_rq is called over
ide_cd_error_cmd() to partially complete the rq. The block layer
does partial completion only for requests with bio's and if the
rq doesn't have one (eg 'GPCMD_READ_DISC_INFO') the request is
completed as a whole and the drive->hwif->rq pointer set to NULL
afterwards. When calling ide_complete_rq again to report
the error, this null pointer is derefenced, resulting in a kernel
crash.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=13399.

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.

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.

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.
