hwmon/f71882fg: Make the decision wether to register fan attr. per fan
Before this patch the f71882fg driver completely fails to initialize
on systems which have reserved settings in the pwm enable register, and
it disables all auto pwm sysfs attributes if any fan is controlled by
a digital sensor reading.
This patch changes the fail to initialize into don't register any attributes
for the fan for which there are reserved settings in the pwm enable register
and also makes the not registering of auto pwm sysfs attributes a per fan
thing.

hwmon: (pmbus) Always call _pmbus_read_byte in core driver
Always call _pmbus_read_byte() instead of pmbus_read_byte() in PMBus core
driver. With this change, device specific read functions can be implemented for
all registers.
Since the device specific read_byte function is now always called, we need to be
more careful with page validations. Only fail if the passed page number is larger
than 0, since -1 means "current page".

ADM1275 supports a second current limit, which can be configured as either lower

Also replace error return code EINVAL for unsupported pages with ENXIO as this
is more appropriate for the observed condition.

hwmon: (pmbus) Don't return errors from driver remove functions
Driver remove functions have an error return value, but rarely return an error
in practice. If a driver does return an error from its remove function, the
driver won't be unloaded and is expected to stay alive.
pmbus_do_remove() is defined as returning an int, but always returns 0 (no
error). Calling code passes that return value on to high level driver
remove functions, but does not evaluate it and removes driver data even if
pmbus_do_remove() returned an error (which it in practice never does). Even if
this code could never cause a real problem, it is nevertheless conceptually
wrong.
To reduce confusion and simplify the code, change pmbus_do_remove() to be a void
function, and have PMBus client drivers always return zero in their driver
remove functions.

hwmon: (coretemp) Let the user force TjMax
On old CPUs (and even some recent Atom CPUs) TjMax can't be read from
the CPU registers, so it is guessed by the driver using a complex
heuristic which isn't reliable. So let users who know their CPU's
TjMax pass it as a module parameter.

when failure was expected, and don't report TjMax in the logs unless
debugging is enabled.

ipv6: don't use inetpeer to store metrics for routes.
Current IPv6 implementation uses inetpeer to store metrics for
routes. The problem of inetpeer is that it doesn't take subnet
prefix length in to consideration. If two routes have the same
address but different prefix length, they share same inetpeer.
So changing metrics of one route also affects the other. The
fix is to allocate separate metrics storage for each route.

bna: Eliminate Small Race Condition Window in RX Path
Change details:
- In a continuous sequence of ifconfig up/down operations, there is a small
window of race between bnad_set_rx_mode() and bnad_cleanup_rx() while the
former tries to access rx_info->rx & the latter sets it to NULL. This race
could lead to bna_rx_mode_set() being called with a NULL (rx_info->rx)
pointer and a crash.
- Hold bnad->bna_lock while setting / unsetting rx_info->rx in bnad_setup_rx()
& bnad_cleanup_rx(), thereby eliminating the race described above.

By protecting these, the architecture can still re-use the
