As reported by Damien Thebault, the double POSTROUTING hook invocation
fix caused outgoing packets routed between two bridges to appear without
a link-layer header. The reason for this is that we're skipping the
br_nf_post_routing hook for routed packets now and don't save the
original link layer header, but nevertheless tries to restore it on
output, causing corruption.
The root cause for this is that skb->nf_bridge has no clearly defined
lifetime and is used to indicate all kind of things, but that is
quite complicated to fix. For now simply don't touch these packets
and handle them like packets from any other device.

When copying entries to user, the kernel makes two passes through the
data, first copying all the entries, then fixing up names and counters.
On the second pass it copies the kernel and match data from userspace
to the kernel again to find the corresponding structures, expecting
that kernel pointers contained in the data are still valid.
This is obviously broken, fix by avoiding the second pass completely
and fixing names and counters while dumping the ruleset, using the
kernel-internal data structures.

I'm using a Marvell 88E8062 on a custom PPC64 blade and ran into RX
lockups while validating the sky2 driver. The receive MAC FIFO would
become stuck during testing with high traffic. One port of the 88E8062
would lockup, while the other port remained functional. Re-inserting
the sky2 module would not fix the problem - only a power cycle would.
I looked over Marvell's most recent sk98lin driver and it looks like
they had a "workaround" for the Yukon XL that the sky2 doesn't have yet.
The sk98lin driver disables the RX MAC FIFO flush feature for all
revisions of the Yukon XL.
According to skgeinit.c of the sk98lin driver, "Flushing must be enabled
(needed for ASF see dev. #4.29), but the flushing mask should be
disabled (see dev. #4.115)". Nice. I implemented this same change in
the sky2 driver and verified that the RX lockup I was seeing was
resolved.

The __weak definition of plat_time_init was only ever meant to be a
migration helper to keep platforms that don't have a plat_time_init
compiling. A few greps says that all platforms now supply their own
plat_time_init() so the weak definition is no longer needed. So I
instead delete it.

Currently it's impossible to build a ps3_defconfig which will reboot
without modules installed. This makes it all too easy to find yourself
with a PS3 that won't reboot.
This is because the system manager driver, which provides the reboot
mechanism, is only selectable if PS3_ADVANCED is set, else it defaults
to m. In ps3_defconfig PS3_ADVANCED is not set, therefore the system
manager is built as a module.
It would be desirable IMHO for the defconfig to produce a kernel that
boots and reboots, without needing modules to be installed.

This patch fixes rounding bug in emulation for double float operating on PowerPC platform.
When pack double float operand, it need to truncate the tail due to the limited precision.
If the truncated part is not zero, the last bit of work bit (totally 3 bits) need to '|' 1.
This patch is completed in _FP_FRAC_SRS_2(X,N,sz) (arch/powerpc/math-emu/op-2.h).
Originally the code leftwards rotates the operand to just keep the truncated part,
then check whether it is zero. However, the number it rotates is not correct when
N is not smaller than _FP_W_TYPE_SIZE, and it will cause the work bit '|' 1 in the improper case.
This patch fixes this issue.

Printk was observed to hang during module unload due to a limited

only reexpands when we receive an ack from the HV and the spinlock here
prevents us from ever processing that ack. This fixes it by dropping
the lock before doing the printk, then looping back to the top to

Starting in 2.6.23...
Several reports from X60 users complained that the default Lenovo keymap
issuing EV_KEY KEY_BRIGHTNESS_UP/DOWN input events caused major issues when
the proper brightness support through ACPI video.c was loaded.
Therefore, remove the generation of these events by default, which is the
right thing for T60, X60, R60, T61, X61 and R61 with their latest BIOSes.
Distros that want to misuse these events into OSD reporting (which requires
an ugly hack from hell in HAL) are welcome to set up the key map they need
through HAL. That way, we don't break everyone else's systems.
