Using the parent functions frame pointer to access our arguments is
completely wrong, whether or not we're building with frame pointers
or not. What we should be using is the stack pointer to get at the
word above the registers we stacked ourselves.

qnap_tsx1x_register_flash is only called by qnap_ts219_init and
qnap_ts41x_init which both live in .init.text, too. So the move is OK.
This fixes the following warning in kirkwood_defconfig:
WARNING: vmlinux.o(.text+0x9334): Section mismatch in reference from the function qnap_tsx1x_register_flash() to the variable .init.data:qnap_tsx1x_spi_slave_info
The function qnap_tsx1x_register_flash() references
the variable __initdata qnap_tsx1x_spi_slave_info.
This is often because qnap_tsx1x_register_flash lacks a __initdata
annotation or the annotation of qnap_tsx1x_spi_slave_info is wrong.

the different putc variants used an initialized local static variable
which is broken since
5de813b (ARM: Eliminate decompressor -Dstatic= PIC hack)
This needs to be initialized at runtime and so needs to be global.
While at it give it a better name.

With conn-track zones and probably with different network
namespaces, the netfilter logic needs to be re-calculated
on packet receive. If the netfilter logic is not reset,
it will not be recalculated properly. This patch adds
the nf_reset logic to dev_forward_skb.

BIOS scripts usually make an attempt to reset the AGP controller,
however on some nv4x cards doing it properly involves switching FW off
and on: if we do that without updating the AGP bridge settings
accordingly (e.g. with the corresponding calls to agp_enable()) we
will be locking ourselves out of the card MMIO space. Do it from
nouveau_mem_reset_agp() before the init scripts are executed.

There's a report of this quirk breaking modesetting on at least one board.
After discussion with Francisco Jerez, we've decided to remove it:
<darktama> it's not worth limiting the quirk to just where we know it can
work? i'm happy either way really :)
<curro> hmm, don't think so, most if not all DCB15 cards have just one DAC
<curro> and with that quirk there's no way to tell if the load comes from
the VGA or DVI port

Fix subsequent suspends by issuing tpm_continue_selftest during resume.
Otherwise, the tpm chip seems to be not fully initialized and will reject
the save state command during suspend, thus preventing the whole system
to suspend.

This fixes hang when target device of mirred packet classifier
action is removed.
If a mirror or redirection action is configured to cause packets
to go to another device, the classifier holds a ref count, but was assuming
the adminstrator cleaned up all redirections before removing. The fix
is to add a notifier and cleanup during unregister.
The new list is implicitly protected by RTNL mutex because
it is held during filter add/delete as well as notifier.

There are still some LRO cards that cause GSO errors in tun,
and BUG on this is an unfriendly way to tell the admin
to disable LRO.
Further, experience shows we might have more GSO bugs lurking.
See https://bugzilla.kernel.org/show_bug.cgi?id=16413
as a recent example.
dumping a packet will make it easier to figure it out.
Replace BUG with warning+dump+drop the packet to make
GSO errors in tun less critical and easier to debug.

After:
commit 6146b1a4da98377e4abddc91ba5856bef8f23f1e
Author: Jay Vosburgh <fubar@us.ibm.com>
Date: Tue Nov 4 17:51:15 2008 -0800
bonding: Fix ALB mode to balance traffic on VLANs
the dev field in the RLB ARP packet handler was set to NULL to wildcard
and accommodate balancing VLANs on top of bonds.
This has the side-effect of the packet handler being called against
other, non RLB-enabled bonds, and a kernel oops results when it tries to
dereference rx_hashtbl in rlb_update_entry_from_arp(), which won't be
set for those bonds, e.g. active-backup.
With the __netif_receive_skb() changes from:
commit 1f3c8804acba841b5573b953f5560d2683d2db0d
Author: Andy Gospodarek <andy@greyhouse.net>
Date: Mon Dec 14 10:48:58 2009 +0000
bonding: allow arp_ip_targets on separate vlans to use arp validation
frames received on VLANs correctly make their way to the bond's handler,
so we no longer need to wildcard the device.
The oops can be reproduced by:
modprobe bonding
echo active-backup > /sys/class/net/bond0/bonding/mode
echo 100 > /sys/class/net/bond0/bonding/miimon
ifconfig bond0 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx
echo +eth0 > /sys/class/net/bond0/bonding/slaves
echo +eth1 > /sys/class/net/bond0/bonding/slaves
echo +bond1 > /sys/class/net/bonding_masters
echo balance-alb > /sys/class/net/bond1/bonding/mode
echo 100 > /sys/class/net/bond1/bonding/miimon
ifconfig bond1 xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx
echo +eth2 > /sys/class/net/bond1/bonding/slaves
echo +eth3 > /sys/class/net/bond1/bonding/slaves
Pass some traffic on bond0. Boom.
[ Tested, behaves as advertised. I do not believe a test of the bonding
mode is necessary, as there is no race between the packet handler and
the bonding mode changing (the mode can only change when the device is
closed). Also updated the log message to include the reproduction and
full commit ids. -J ]

Commit 2a6b69765ad794389f2fc3e14a0afa1a995221c2
(ACPI: Store NVS state even when entering suspend to RAM) caused the
ACPI suspend code save the NVS area during suspend and restore it
during resume unconditionally, although it is known that some systems
need to use acpi_sleep=s4_nonvs for hibernation to work. To allow
the affected systems to avoid saving and restoring the NVS area
during suspend to RAM and resume, introduce kernel command line
option acpi_sleep=nonvs and make acpi_sleep=s4_nonvs work as its
alias temporarily (add acpi_sleep=s4_nonvs to the feature removal
file).
