powerpc: Keep xtime and gettimeofday in sync
This fixes a regression which was introduced by moving ppc32 to use
the same sort of lockless gettimeofday as ppc64 has been using for
some time. This involves getting the timebase and performing some
simple arithmetic to convert it to seconds and microseconds. However,
the factor and offset used there weren't being updated when NTP
varied the tick length using adjtimex. 64-bit didn't notice the
problem because it had a hook in the 32-bit adjtimex compat routine
that attempted to work out what the generic timekeeping code would
do and alter the factor and offset to match. However, that code
was very complex and it wasn't clear that it still matched what the
generic code would do.
Now we use the generic current_tick_length() routine that was recently
added to check that the current tick will be as long as we expect; if
not we recompute the factor and offset. This keeps gettimeofday and
xtime in sync. In addition we check that gettimeofday hasn't got ahead
of xtime on each timer interrupt; if it has, we resync.

[PATCH] ACPI: fix vendor resource length computation
acpi_rs_get_list_length() needs to account for all the vendor-defined data

which causes slab corruption when we later convert AML to resources and run
off the end of the buffer.
This causes slab corruption on machines that use ACPI vendor-defined

[PATCH] fix deadlock in ext2
Fix a deadlock possible in the ext2 file system implementation. This
deadlock occurs when a file is removed from an ext2 file system which was
mounted with the "sync" mount option.
The problem is that ext2_xattr_delete_inode() was invoking the routine,
sync_dirty_buffer(), using a buffer head which was previously locked via
lock_buffer(). The first thing that sync_dirty_buffer() does is to lock
the buffer head that it was passed. It does this via lock_buffer(). Oops.
The solution is to unlock the buffer head in ext2_xattr_delete_inode()
before invoking sync_dirty_buffer(). This makes the code in
ext2_xattr_delete_inode() obey the same locking rules as all other callers
of sync_dirty_buffer() in the ext2 file system implementation.

[PATCH] Provide an interface for getting the current tick length
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.

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)

[PATCH] wireless/atmel: fix Open System authentication process bugs
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.

[PATCH] neofb: avoid resetting display config on unblank (v2)
There were two mistakes in the register-read-on-(un)blank approach.
- First, without proper register (un)locking the value read back will always
be zero, and this is what I missed entirely until just now. Due to this,
the logic could not be verified at all and I tried some bogus checks which
are completely stupid.
- Second, the LCD status bit will always be set to zero when the backlight
has been turned off. Reading the value back during unblank will disable the
LCD unconditionally, regardless of the state it is supposed to be in, since
we set it to zero beforehand.
So this is what we do now:
- create a new variable in struct neofb_par, and use that to determine
whether to read back registers (initialized to true)
- before actually blanking the screen, read back the register to sense any
possible change made through Fn key combo
- use proper neoUnlock() / neoLock() to actually read something
- every call to neofb_blank() determines if we read back next time: blanking
disables readback, unblanking (FB_BLANK_UNBLANK) enables it
This should give us a nice and clean state machine. Has been thoroughly
tested on a Dell Latitude CPiA / NM220 Chip docked to a C/Dock2 with attached
CRT in all possible combinations of LCD/CRT on/off. I changed the config via
Fn key, let the console blank, unblanked by keypress - works flawlessly.

[NETFILTER]: x_tables: fix dependencies of conntrack related modules
NF_CONNTRACK_MARK is bool and depends on NF_CONNTRACK which is
tristate. If a variable depends on NF_CONNTRACK_MARK and doesn't take
care about NF_CONNTRACK, it can be y even if NF_CONNTRACK isn't y.
NF_CT_ACCT have same issue, too.

[XFRM]: Fix SNAT-related crash in xfrm4_output_finish
When a packet matching an IPsec policy is SNATed so it doesn't match any
policy anymore it looses its xfrm bundle, which makes xfrm4_output_finish
crash because of a NULL pointer dereference.
This patch directs these packets to the original output path instead. Since
the packets have already passed the POST_ROUTING hook, but need to start at
the beginning of the original output path which includes another
POST_ROUTING invocation, a flag is added to the IPCB to indicate that the
packet was rerouted and doesn't need to pass the POST_ROUTING hook again.

[IA64] ia64: simplify and fix udelay()
The original ia64 udelay() was simple, but flawed for platforms without
synchronized ITCs: a preemption and migration to another CPU during the
while-loop likely resulted in too-early termination or very, very
lengthy looping.
The first fix (now in 2.6.15) broke the delay loop into smaller,
non-preemptible chunks, reenabling preemption between the chunks. This
fix is flawed in that the total udelay is computed to be the sum of just
the non-premptible while-loop pieces, i.e., not counting the time spent
in the interim preemptible periods. If an interrupt or a migration
occurs during one of these interim periods, then that time is invisible
and only serves to lengthen the effective udelay().
This new fix backs out the current flawed fix and returns to a simple
udelay(), fully preemptible and interruptible. It implements two simple
alternative udelay() routines: one a default generic version that uses
ia64_get_itc(), and the other an sn-specific version that uses that
platform's RTC.
