Users report problems w/ auto-negotiation disabled and the link set
to 100/Half or 10/Half.  Problems range from poor performance to no
link at all.

The current sky2 code does not set things properly on link up if
autonegotiation is disabled.  Plus it does not contemplate a 10Mbit
setting at all.  This patch corrects that.

This provides an interface for arch code to find out how many
nanoseconds are going to be added on to xtime by the next call to
do_timer.  The value returned is a fixed-point number in 52.12 format
in nanoseconds.  The reason for this format is that it gives the
full precision that the timekeeping code is using internally.

The motivation for this is to fix a problem that has arisen on 32-bit
powerpc in that the value returned by do_gettimeofday drifts apart
from xtime if NTP is being used.  PowerPC is now using a lockless
do_gettimeofday based on reading the timebase register and performing
some simple arithmetic.  (This method of getting the time is also
exported to userspace via the VDSO.)  However, the factor and offset
it uses were calculated based on the nominal tick length and weren't
being adjusted when NTP varied the tick length.

Note that 64-bit powerpc has had the lockless do_gettimeofday for a
long time now.  It also had an extremely hairy routine that got called
from the 32-bit compat routine for adjtimex, which adjusted the
factor and offset according to what it thought the timekeeping code
was going to do.  Not only was this only called if a 32-bit task did
adjtimex (i.e. not if a 64-bit task did adjtimex), it was also
duplicating computations from kernel/timer.c and it wasn't clear that
it was (still) correct.

The simple solution is to ask the timekeeping code how long the
current jiffy will be on each timer interrupt, after calling
do_timer.  If this jiffy will be a different length from the last one,
we then need to compute new values for the factor and offset used in
the lockless do_gettimeofday.  In this way we can keep xtime and
do_gettimeofday in sync, even when NTP is varying the tick length.

Note that when adjtimex varies the tick length, it almost always
introduces the variation from the next tick on.  The only case I could
see where adjtimex would vary the length of the current tick is when
an old-style adjtime adjustment is being cancelled.  (It's not clear
to me why the adjustment has to be cancelled immediately rather than
from the next tick on.)  Thus I don't see any real need for a hook in
adjtimex; the rare case of an old-style adjustment being cancelled can
be fixed up at the next tick.

The memory allocator doesn't like empty zones (which have an
uninitialized freelist), so a x86-64 system with a node fully
in GFP_DMA32 only would crash on mbind.

Fix that up by putting all possible zones as fallback into the zonelist
and skipping the empty ones.

In fact the code always enough allocated space for all zones,
but only used it for the highest. This change just uses all the
memory that was allocated before.

This should work fine for now, but whoever implements node hot removal
needs to fix this somewhere else too (or make sure zone datastructures
by itself never go away, only their memory)

This patch fixes a number of bugs in the authentication process:

1) When falling back to Shared Key authentication mode from Open System,
a missing 'return' would cause the auth request to be sent, but would
drop the card into Management Error state.  When falling back, the
driver should also indicate that it is switching to Shared Key mode by
setting exclude_unencrypted.

2) Initial authentication modes were apparently wrong in some cases,
causing the driver to attempt Shared Key authentication mode when in
fact the access point didn't support that mode or even had WEP disabled.
The driver should set the correct initial authentication mode based on
wep_is_on and exclude_unencrypted.

3) Authentication response packets from the access point in Open System
mode were getting ignored because the driver was expecting the sequence
number of a Shared Key mode response.  The patch separates the OS and SK
mode handling to provide the correct behavior.
