2007-02-13i2c-viapro: Add support for the VIA CX700 south bridgeJean Delvare
We do not have any documentation for the CX700, but it was reported to work fine. Thanks to Claas Langbehn for testing. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-13i2c: Add IDs to adaptersStephen Hemminger
IDs have been defined but not used by most of the I2C adapters. By having a unique ID, clients can check for correct connection during probe. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-13i2c: Update the list of bus IDsJean Delvare
* The Voodoo3 has no SMBus, it has two bit-banged busses which already have an ID assigned (I2C_HW_B_VOO). * The i2c-ipmi bus driver was a non-sense, it'll never be ported to Linux 2.6. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Yani Ioannou <yani.ioannou@gmail.com>
2007-02-13i2c: Add driver suspend/resume/shutdown supportDavid Brownell
Driver model updates for the I2C core: - Add new suspend(), resume(), and shutdown() methods. Use them in the standard driver model style; document them. - Minor doc updates to highlight zero-initialized fields in drivers, and the driver model accessors for "clientdata". If any i2c drivers were previously using the old suspend/resume calls in "struct driver", they were getting warning messages ... and will now no longer work. Other than that, this patch changes no behaviors; and it lets I2C drivers use conventional PM and shutdown support.

2007-02-13i2c: completion header cleanupsJean Delvare
i2c-core and i2c-isa use completions without including <linux/completion.h>. Fix it. i2c-powermac includes <linux/completion.h> but doesn't use any completion. Fix it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Brownell <david-b@pacbell.net>
2007-02-13i2c-i801: Document the SMBus unhiding quirkJean Delvare
This is a frequently asked question so it deserves a paragraph in the driver documentation. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2007-02-13i2c/vt8231: Remove superfluous initializationDavid Brownell
Remove a superfluous initialization from the vt8231 hwmon driver; the i2c core does this, and the source field will be vanishing soon. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-13i2c-ali1563: Fix device initializationJean Delvare
The i2c-ali1563 initialization looks quite broken to me: * If the I/O space isn't enabled, we forcibly set 3 bits in the PCI configuration space instead of just the one enabling the I/O space. * After that we pretend to check if the write worked, but we don't actually read the new value from the register. * It's probably not a good idea to enable the I/O space if no base address has been set. So I propose the following changes to that part of the driver: * Merge ali1563_enable() into ali1563_setup(). * Check the base address before the I/O space enabled bit.

2007-02-12[SPARC]: Re-export saved_command_line to modules.David S. Miller
This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by: David S. Miller <davem@davemloft.net>

2007-02-12don't use 'localversion*' files twiceLinus Torvalds
Since we look in both source and object directories for localversion* files, we accidentally ended up getting them twice. Use 'sort -u' to avoid that. Reported-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-02-12[NETFILTER]: ip6t_mh: drop piggyback payload packet on MH packetsMasahide NAKAMURA
Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise it must be discarded (and the receiver should send ICMP error). We assume filter should drop such piggyback everytime to disallow slipping through firewall rules, even the final receiver will discard it.

2007-02-12[NETFILTER]: nf_conntrack: change nf_conntrack_l[34]proto_unregister to voidPatrick McHardy
No caller checks the return value, and since its usually called within the module unload path there's nothing a module could do about errors anyway, so BUG on invalid conditions and return void. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-02-12[NETFILTER]: nf_conntrack: fix invalid conntrack statistics RCU assumptionPatrick McHardy
NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables preemption as well, making it legal to use __get_cpu_var without disabling preemption manually. The assumption is not correct anymore with preemptable RCU, additionally we need to protect against softirqs when not holding nf_conntrack_lock. Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs, and use where necessary. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
