2008-07-18sctp: Don't abort initialization when CONFIG_PROC_FS=nFlorian Westphal
This puts CONFIG_PROC_FS defines around the proc init/exit functions and also avoids compiling proc.c if procfs is not supported. Also make SCTP_DBG_OBJCNT depend on procfs.

2008-07-18tcp: RTT metrics scalingStephen Hemminger
Some of the metrics (RTT, RTTVAR and RTAX_RTO_MIN) are stored in kernel units (jiffies) and this leaks out through the netlink API to user space where the units for jiffies are unknown. This patches changes the kernel to convert to/from milliseconds. This changes the ABI, but milliseconds seemed like the most natural unit for these parameters. Values available via syscall in /proc/net/rt_cache and netlink will be in milliseconds. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-18pkt_sched: Fix noqueue_qdisc initialization.David S. Miller
Like noop_qdisc, it needs a dummy backpointer and explicit qdisc->q.lock initialization. Based upon a report by Stephen Hemminger. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-18pkt_sched: Manage qdisc list inside of root qdisc.David S. Miller
Idea is from Patrick McHardy. Instead of managing the list of qdiscs on the device level, manage it in the root qdisc of a netdev_queue. This solves all kinds of visibility issues during qdisc destruction. The way to iterate over all qdiscs of a netdev_queue is to visit the netdev_queue->qdisc, and then traverse it's list. The only special case is to ignore builting qdiscs at the root when dumping or doing a qdisc_lookup(). That was not needed previously because builtin qdiscs were not added to the device's qdisc_list.

2008-07-19Input: add switch for dock eventsMatthew Garrett
Add a SW_DOCK switch to input.h. ACPI docks currently send their docking status as a uevent, but not all docks are ACPI or correspond to a device. In that case, it makes more sense to simply generate an input event on docking or undocking.

2008-07-19Input: add option to disable HP SDC driverHelge Deller
Add "no_hpsdc" kernel module option to the hp_sdc driver, so that the driver can be instructed to not enable the HP SDC port. This is useful on some older HPPA boxes with HIL keyboard and HIL mouse where the new HP SDC HIL drivers don't work yet. By disabling the new hp_sdc driver users are able to use the older hilkbd driver instead. Signed-off-by: Helge Deller <deller@gmx.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2008-07-18pkt_sched: Get rid of u32_list.David S. Miller

2008-07-18x86: I/O APIC: Always report how the timer has been set upMaciej W. Rozycki
Following recent (and less so) issues with the 8254 timer when routed through the I/O or local APIC, always report which configurations have been tried and which one has been set up eventually. This is so that logs posted by people for some other reason can be used as a cross-reference when investigating any possible future problems. The change unifies messages printed on 32-bit and 64-bit platforms and adds trailing newlines (removes leading ones), so that proper log level annotation can be used and any possible interspersed output will not cause a mess. I have chosen to use apic_printk(APIC_QUIET, ...) rather than printk(...) so that the distinction of these messages is maintained making possible future decisions about changes in this area easier. A change posted separately making apic_verbosity unsigned removes any extra code that would otherwise be generated as a result of this design decision. Signed-off-by: Maciej W.
