powerpc: Estimate G5 cpufreq transition latency
Setting G5's cpu frequency transition latency to CPUFREQ_ETERNAL stops
ondemand governor from working. I measured the latency using sched_clock
and haven't seen much higher than 11000ns, so I set this to 12000ns for
my configuration. Possibly other configurations will be different?
Ideally the generic code would be able to measure it in case the platform
does not provide it.
But this simple patch at least makes it throttle again.

This reverts commit
e088e4c9cdb618675874becb91b2fd581ee707e6.
Removing the sysfs interface for p4-clockmod was flagged as a
regression in bug 12826.
Course of action:
- Find out the remaining causes of overheating, and fix them
if possible. ACPI should be doing the right thing automatically.
If it isn't, we need to fix that.
- mark p4-clockmod ui as deprecated
- try again with the removal in six months.
It's not really feasible to printk about the deprecation, because
it needs to happen at all the sysfs entry points, which means adding
a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

Reason for this is that cpu time accounting usually only happens from
interrupt context, but acct_update_integrals gets also called from
process context with interrupts enabled.
So in acct_update_integrals we may end up with the following scenario:
Between reading tsk->stime/tsk->utime and tsk->acct_timexpd an interrupt
happens which updates accouting values. This causes acct_timexpd to be
greater than the former stime + utime. The subsequent calculation of
dtime = cputime_sub(time, tsk->acct_timexpd);
will be negative and the division performed by
cputime_to_jiffies(dtime)
will generate an exception since the result won't fit into a 32 bit
register.
In order to fix this just always disable interrupts while accessing any
of the accounting values.

i2c-mpc: do not allow interruptions when waiting for I2C to complete
The i2c_wait() function is using wait_event_interruptible_timeout() to wait for
the I2C controller to signal that it has completed an I2C bus operation. If
the process that causes the I2C operation terminated abruptly, the wait will
be interrupted, returning an error. It is better to let the I2C operation
finished before the process exits.
It is safe to use wait_event_timeout() instead, because the timeout will allow
the process to exit if the I2C bus hangs. It's also better to allow the
I2C operation to finish, because unacknowledged I2C operations can cause the
I2C bus to hang.

The fix is not correct for all supported orion5x platforms, but since
the supported platforms right now are 133 Mhz and 166 Mhz, it won't

This was caused by libata trusting the drive's reported current capacity in
sectors in identify words 57 and 58 if the drive does not support LBA and the
current CHS translation values appear valid. Unfortunately it seems older
ATA specs were vague about what this field should contain and a number of drives
used values with wrong byte order or that were totally bogus. There's no
unique information that it conveys and so we can just calculate the number
of sectors from the reported current CHS values.

libata: make sure port is thawed when skipping resets
When SCR access is available and the link is offline, softreset is
skipped as it only wastes time and some controllers don't respond very
well. However, the skip path forgot to thaw the port, which not only
blocks further event notification from the port but also causes
repeated EH invocations on the same event on drivers which rely on
->thaw() to clear events if the IRQ is shared with another device or
port.
This problem has always been there but is uncovered by recent sata_nv
nf2/3 change which dropped hardreset support while maintaining SCR
access. nf2/3 doesn't clear hotplug event mask from the interrupt
handler but relies on ->thaw() to clear them. When the hardreset was
there, the reset action was never skipped and the port was always
thawed but, with the hardreset gone, ->prereset() determines that
there's no need for softreset and both ->softreset() and ->thaw() are
skipped. This leads to stuck hotplug event in the IRQ status register
triggering hotplug event whenever IRQ is delieverd on the same IRQ.
As the controller shares the same IRQ for both ports, this happens on
every IO if one port is occpupied and the other isn't.
This patch fixes the problem by making sure that the port is thawed on
reset-skip path.

vlan: Fix vlan-in-vlan crashes.
As analyzed by Patrick McHardy, vlan needs to reset it's
netdev_ops pointer in it's ->init() function but this
leaves the compat method pointers stale.
Add a netdev_resync_ops() and call it from the vlan code.
Any other driver which changes ->netdev_ops after register_netdevice()
will need to call this new function after doing so too.
With help from Patrick McHardy.

Blackfin arch: fix bug - The SPORT_HYS bit is not set for BF561 0.5
IMHO the setting should depend on ANOMALY_05000305 which is about the
availability of the bit, not ANOMALY_05000265 which only describes the
SPORT sensitivity to noise (checked for BF561 only, though).
If that's not true for other BF variants, maybe the definition of
ANOMALY_05000265 for BF561 should be changed to '(1)' instead.

pkt_sched: act_police: Fix a rate estimator test.
A commit
c1b56878fb68e9c14070939ea4537ad4db79ffae "tc: policing requires
a rate estimator" introduced a test which invalidates previously working
configs, based on examples from iproute2: doc/actions/actions-general.
This is too rigorous: a rate estimator is needed only when police's
"avrate" option is used.

ext4: fix ext4_free_inode() vs. ext4_claim_inode() race
I was seeing fsck errors on inode bitmaps after a 4 thread
dbench run on a 4 cpu machine:
Inode bitmap differences: -50736 -(50752--50753) etc...
I believe that this is because ext4_free_inode() uses atomic
bitops, and although ext4_new_inode() *used* to also use atomic
bitops for synchronization, commit
393418676a7602e1d7d3f6e560159c65c8cbd50e changed this to use
the sb_bgl_lock, so that we could also synchronize against
read_inode_bitmap and initialization of uninit inode tables.
However, that change left ext4_free_inode using atomic bitops,
which I think leaves no synchronization between setting &
unsetting bits in the inode table.
The below patch fixes it for me, although I wonder if we're
getting at all heavy-handed with this spinlock...

tg3: Fix 5906 link problems
Commit
6833c043f9fc03696fde623914c4a0277df2a0bc introduced the phy
auto-powerdown capability. While the APD feature only works for 5761
and 5784 asic revisions, the (harmless portion of the) code was applied
to all 5705 and newer devices. However, the 5906 phy departs from the
usual design. This commit was interfering with the 5906's ability to
negotiate link against some switches. This patch corrects the problem.
