vmlinux.lds expects the fixup code to be on a section named .fixup. The
.text.fixup section is not mentioned on vmlinux.lds, and is included on
the resulting vmlinux (just after .text) only because of ld heuristics on
placing orphan sections.However, placing .text.fixup outside .text breaks the definition of
_etext, making it exclude the .text.fixup contents. That makes .text.fixup
be ignored by the kernel initialization code that needs to know about
section locations, such as the code setting page protection bits.Signed-off-by: Eduardo Habkost

The acer_wmi driver does a DMI scan for quirks, and then sets flags into the
"interface" datastructure for some cases. However, the quirks happen real early
before "interface" is per se initialized from NULL.The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the
end, when "interface" has it's final value.Reported-by: kerneloops.org

This fixes a problem spotted with zebra, but not sure if it is
necessary a kernel problem. With IPV6 when an address is added to an
interface, Zebra creates a duplicate RIB entry, one as a connected
route, and other as a kernel route.When an address is added to an interface the RTN_NEWADDR message
causes Zebra to create a connected route. In IPV4 when an address is
added to an interface a RTN_NEWROUTE message is set to user space with
the protocol RTPROT_KERNEL. Zebra ignores these messages, because it
already has the connected route.The problem is that route created in IPV6 has route protocol ==
RTPROT_BOOT. Was this a design decision or a bug? This fixes it. Same
patch applies to both net-2.6 and stable.Signed-off-by: Stephen Hemminger

Authenc works in two stages for encryption, it first encrypts and
then computes an ICV. The context memory of the request is used
by both operations. The problem is that when an asynchronous
encryption completes, we will compute the ICV and then reread the
context memory of the encryption to get the original request.It just happens that we have a buffer of 16 bytes in front of the
request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger
the bug. However, any attempt to uses a larger ICV instantly kills
the machine when the first asynchronous encryption is completed.This patch fixes this by saving the request pointer before we start
the ICV computation.Signed-off-by: Herbert Xu

The function __cpuinit uv_cpu_init() references
a function __init uv_system_init().
If uv_system_init is only used by uv_cpu_init then
annotate uv_system_init with a matching annotation.uv_system_init was ment to be called only once, so do it from codepath
(native_smp_prepare_cpus) which is called once, right before activation
of other cpus (smp_init).Note: old code relied on uv_node_to_blade being initialized to 0,
but it'a not initialized from anywhere.Signed-off-by: Marcin Slusarz

Since some qdiscs call qdisc_tree_decrease_qlen() (so qdisc_lookup())
without rtnl_lock(), adding and deleting from a qdisc list needs
additional locking. This patch adds global spinlock qdisc_list_lock
and wrapper functions for modifying the list. It is considered as a
temporary solution until hfsc_dequeue(), netem_dequeue() and
tbf_dequeue() (or qdisc_tree_decrease_qlen()) are redone.With feedback from Herbert Xu and David S. Miller.

Dave Müller sent a diff for the pata_oldpiix that highlighted a problem
where a lot of the ATA drivers assume dma_mode == 0 means "no DMA" while
the core code uses 0xFF.This turns out to have other consequences such as code doing >= XFER_UDMA_0
also catching 0xFF as UDMAlots. Fortunately it doesn't generally affect
set_dma_mode, although some drivers call back into their own set mode code
from other points.Having been through the drivers I've added helpers for using_udma/using_mwdma
dma_enabled so that people don't open code ranges that may change (eg if UDMA8
appears somewhere)Thanks to David for the initial bits

SIS controllers were blacklisted for PMP as enabling it made device
detection fail whether the device was PMP or not - the natural
conclusion was the controller chokes on SRST w/ pmp==15. However, it
turned out that the controller just didn't like issuing SRST after
hardreset w/o clearing SError first. Interestingly, the SRST itself
succeeds but the following commands fail.If SError is cleared between hardreset and SRST, which is the default
behavior now, everything works fine and SIS controllers work with PMPs
happily.Remove PMP blacklisting for SIS AHCIs.

Save SControl during probing and restore it on detach. This prevents
adjustments made by libata drivers to seep into the next driver which
gets attached (be it a libata one or not).It's not clear whether SControl also needs to be restored on suspend.
The next system to have control (ACPI or kexec'd kernel) would
probably like to see the original SControl value but there's no
guarantee that a link is gonna keep working after SControl is adjusted
without a reset and adding a reset and modified recovery cycle soley
for this is an overkill. For now, do it only for detach.Signed-off-by: Tejun Heo

Signed-off-by: Jeff Garzik -
As an optimization, follow-up SRST used to be skipped if
classification wasn't requested even when hardreset requested it via
-EAGAIN. However, some hardresets can't wait for device readiness and
skipping SRST can cause timeout or other failures during revalidation.
Always perform follow-up SRST if hardreset returns -EAGAIN. This
makes reset paths more predictable and thus less error-prone.While at it, move hardreset error checking such that it's done right
after hardreset is finished. This simplifies followup SRST condition
check a bit and makes the reset path easier to modify.Signed-off-by: Tejun Heo

While I don't have a hotplug capable system at hand, I think two issues need
fixing:- pud_phys (in kernel_physical_ampping_init()) would remain uninitialized in
the after_bootmem case- the locking done just around phys_pmd_{init,update}() would leave out pgd
updates, and it was needlessly covering code portions that do allocations
