[PATCH] __cmpxchg() must really always be inlined
With the latest 2.6.15 kernel builds for alpha on Debian, we ran into a
problem with undefined references to __cmpxchg_called_with_bad_pointer() in
a couple of kernel modules (xfs.ko and drm.ko; see
http://bugs.debian.org/347556).
It looks like people have been trying to out-clever each other wrt the
definition of "inline" on this architecture :), with the result that
__cmpxchg(), which must be inlined so the compiler can see its argument is
const, is not guaranteed to be inlined. Indeed, it was not being inlined
when building with -Os.
The attached patch fixes the issue by adding an
__attribute__((always_inline)) explicitly to the definition of __cmpxchg()
instead of relying on redefines of "inline" elsewhere to make this happen.

Ensure a consistent value is read from the STICK register by ensuring
that both high and low are read without high changing due to a roll
over of the low register.
Various Debian/SPARC users (myself include) have noticed problems with
Hummingbird based systems. The symptoms are that the system time is
seen to jump forward 3 days, 6 hours, 11 minutes give or take a few
seconds. In many cases the system then hangs some time afterwards.
I've spotted a race condition in the code to read the STICK register.
I could not work out why 3d, 6h, 11m is important but guess that it is
due to the 2^32 jump of STICK (forwards on one read and then the next
read will seem to be backwards) during a timer interrupt. I'm guessing
that a change of -2^32 will get converted to a large unsigned
increment after the arithmetic manipulation between STICK,
nanoseconds, jiffies etc.
I did a test where I modified __hbird_read_stick to artificially
inject rollover faults forcefully every few seconds. With this I saw
the clock jump over 6 times in 12 hours compared to once every month
or so.

[PATCH] Fix onboard video on SPARC Blade 100 for 2.6.{13,14,15}
I have recently been switching from using 2.4.32 on my trusty
old Sparc Blade 100 to using 2.6.15 . Some of the problems I ran into
were distorted video when the console was active (missing first
character, skipped dots) and when running X windows (colored snow,
stripes, missing pixels). A quick examination of the 2.6 versus 2.4
source for the ATY driver revealed alot of changes.
A closer look at the code/data for the 64GR/XL chip revealed
two minor "typos" that the rewriter(s) of the code made. The first is
a incorrect clock value (230 .vs. 235) and the second is a missing
flag (M64F_SDRAM_MAGIC_PLL). Making both these changes seems to have
fixed my problem. I tend to think the 235 value is the correct one,
as there is a 29.4 Mhz clock crystal close to the video chip and 235.2
(29.4*8) is too close to 235 to make it a coincidence.
The flag for M64F_SDRAM_MAGIC_PLL was dropped during the
changes made by adaplas in file revision 1.72 on the old bitkeeper
repository.
The change relating to the clock rate has been there forever,
at least in the 2.6 tree. I'm not sure where to look for the old 2.5
tree or if anyone cares when it happened.
On SPARC Blades 100's, which use the ATY MACH64GR video chipset, the
clock crystal frequency is 235.2 Mhz, not 230 Mhz. The chipset also
requires the use of M64F_SDRAM_MAGIC_PLL in order to setup the PLL
properly for the DRAM.

After a short exchange, Christoph approved this patch
Some G5s still occasionally experience shutdowns due to overtemp
conditions despite the recent fix. After analyzing logs from such
machines, it appears that the overtemp code is a bit too quick at
shutting the machine down when reaching the critical temperature (tmax +
8) and doesn't leave the fan enough time to actually cool it down. This
happens if the temperature of a CPU suddenly rises too high in a very
short period of time, or occasionally on boot (that is the CPUs are
already overtemp by the time the driver loads).
This patches makes the code a bit more relaxed, leaving a few seconds to
the fans to do their job before kicking the machine shutown.

Don't use printk() where "current_thread_info()" is crap.
Until when we switch to running on init_stack, current_thread_info() evaluates
to crap. Printk uses "current" at times (in detail, ¤t is evaluated with
CONFIG_DEBUG_SPINLOCK to check the spinlock owner task).
And this leads to random segmentation faults.
Exactly, what happens is that ¤t = *(current_thread_info()), i.e. round
down $esp and dereference the value. I.e. access the stack below $esp, which
causes SIGSEGV on a VM_GROWSDOWN vma (see arch/i386/mm/fault.c).

[SERMOUSE]: Sun mice speak 5-byte protocol too.
Noticed by Christophe Zimmerman, this explains the slow mouse movement
with 2.6.x kernels.
And checking the 2.4.x drivers/sbus/char/sunmouse.c driver shows we
always used a 5-byte protocol with Sun mice in the past. I have no
idea how the 3-byte thing got into the 2.6.x driver, but it's surely
wrong.

[TG3]: ethtool -d hangs PCIe systems
Resubmitting after recommendation to use GET_REG32_1() instead of
GET_REG32_LOOP(..., 1). Retested. Problem remains fixed.
Prevent tg3_get_regs() from reading reserved and undocumented registers
at RX_CPU_BASE and TX_CPU_BASE offsets which caused hostile behavior
on PCIe platforms.

[PATCH] Fix more radeon GART start calculation cases
As reported by Jules Villard <jvillard@ens-lyon.fr> and some others, the
recent GART aperture start reconfiguration causes problems on some
setups.
What I _think_ might be happening is that the X server is also trying to
muck around with the card memory map and is forcing it back into a wrong
setting that also happens to no longer match what the DRM wants to do
and blows up. There are bugs all over the place in that code (and still
some bugs in the DRM as well anyway).
This patch attempts to avoid that by using the largest of the 2 values,
which I think will cause it to behave as it used to for you and will
still fix the problem with machines that have an aperture size smaller
than the video memory.

[IPV6] mcast: Fix multiple issues in MLDv2 reports.
The below "jumbo" patch fixes the following problems in MLDv2.
1) Add necessary "ntohs" to recent "pskb_may_pull" check [breaks
all nonzero source queries on little-endian (!)]
2) Add locking to source filter list [resend of prior patch]
3) fix "mld_marksources()" to
a) send nothing when all queried sources are excluded
b) send full exclude report when source queried sources are
not excluded
c) don't schedule a timer when there's nothing to report
NOTE: RFC 3810 specifies the source list should be saved and each
source reported individually as an IS_IN. This is an obvious DOS
path, requiring the host to store and then multicast as many sources
as are queried (e.g., millions...). This alternative sends a full,
relevant report that's limited to number of sources present on the
machine.
4) fix "add_grec()" to send empty-source records when it should
The original check doesn't account for a non-empty source
list with all sources inactive; the new code keeps that
short-circuit case, and also generates the group header
with an empty list if needed.
5) fix mca_crcount decrement to be after add_grec(), which needs
its original value
These issues (other than item #1 ;-) ) were all found by Yan Zheng,
much thanks!

[BR_NETFILTER]: Fix leak if skb traverses > 1 bridge
Call nf_bridge_put() before allocating a new nf_bridge structure and
potentially overwriting the pointer to a previously allocated one.
This fixes a memory leak which can occur when the bridge topology
allows for an skb to traverse more than one bridge.

[PATCH] Fix Fibre Channel boot oops
The oops is characteristic of the underlying device being removed from
visibility before the class device, and sure enough we do device_del()
before transport_unregister() in the scsi_target_reap() routines. I've
no idea why this is suddenly showing up, since the code has been in
there since that function was first invented. However, I've confirmed
this fixes Andrew Vasquez's boot oops.
