Change examples to have master skew above 0 to have ability to overwrite this
from the slave (for example, when master is failing on disk IO and could not be
logged into or execute cronjob).
Commented out examples changed too to simplify future merging.

Make ng_mppc to not disable the node in case of multiple packet loss.
Quite often it can be just packet reorder, and killing link in such case
is inconvenient. Add few sysctl's to control that behavior.

an embedded newline appearing within the options string surrounded by
double-quotes. Rework the logic that goes into setting dataset options on
the root pool dataset while we're here -- added two new variables (which
can be altered via scripting) ZFSBOOT_POOL_CREATE_OPTIONS and also
ZFSBOOT_BOOT_POOL_CREATE_OPTIONS for setting pool/dataset attributes at
the time of pool creation. The former is for setting options on the root
pool (zroot) and the latter is for setting options on the optional separate
boot pool (bootpool) implicitly enabled when using either GELI or MBR. The
default value for the root pool variable (ZFSBOOT_POOL_CREATE_OPTIONS) is
"-O compress=lz4 -O atime=off" and the default value for separate boot pool
variable (ZFSBOOT_BOOT_POOL_CREATE_OPTIONS) is NULL (no additional options
for the separate boot pool dataset).

Fix the "disks" variable reuse.
It starts off being used to track the grammar for the number of disks

Replace the variable with disks_grammar and move 'disk' and 'disks' to
msg_ vars so they can be translated in the future.

Fix DMA handling in radeon_dummy_page_init():
- Based on actual usage and on what Linux does, dummy_page.addr should
contain the physical bus address of the dummy page rather than its
virtual one. As a side-effect, correcting this bug fixes compilation
with PAE support enabled by getting rid of an inappropriate cast.
- Also based on actual usage of dummy_page.addr, theoretically Radeon
devices could do a maximum of 44-bit DMA. In reality, though, it is
more likely that they only support 32-bit DMA, at least that is what
radeon_gart_table_ram_alloc() sets up for, too. However, passing ~0
to drm_pci_alloc() as maxaddr parameter translates to 64-bit DMA on
amd64/64-bit machines. Thus, use BUS_SPACE_MAXSIZE_32BIT instead,
which the existing 32-bit DMA limits within the drm2 code spelled as
0xFFFFFFFF should also be changed to.

Repair nested signal handling on PowerPC. The signal trampoline code
was not allocating space for the parameter save area in the stack frame.
If the compiler chose to save the argument to the signal handler on the
stack, it would overwrite the first 32 bits of the sigaction struct with
it, corrupting it for a subsequent invocation.

Glibc was switched to the FUTEX_WAIT_BITSET op and CLOCK_REALTIME
flag has been added instead of FUTEX_WAIT to replace the FUTEX_WAIT
logic which needs to do gettimeofday() calls before the futex syscall
to convert the absolute timeout to a relative timeout.
Before this the CLOCK_MONOTONIC used by the FUTEX_WAIT_BITSET op.
When the FUTEX_CLOCK_REALTIME is specified the timeout is an absolute
time, not a relative time. Rework futex_wait to handle this.
On the side fix the futex leak in error case and remove useless
parentheses.
Properly calculate the timeout for the CLOCK_MONOTONIC case.

We have two functions from where a geom orphan method could be called:
g_orphan_register and g_resize_provider_event. Both are called from the
event queue. Also we have GEOM_DEV class, which does deferred destroy
for its consumers via g_dev_destroy (also called from the event queue).
So it is possible, that for some consumers an orphan method will be
called twice. This triggers panic in g_dev_orphan.
Check that consumer isn't already orphaned before call orphan method.

In r218101 I have not changed properly the futex syscall definition.
Some Linux futex ops atomically verifies that the futex address uaddr
(uval) contains the value val. Comparing signed uval and unsigned val
may lead to an unexpected result, mostly to a deadlock.
So copyin uaddr to an unsigned int to compare the parameters correctly.
While here change ktr records to print parameters in more readable format.
