2008-07-09netfilter: nf_conntrack_tcp: fix endless loopPatrick McHardy
When a conntrack entry is destroyed in process context and destruction is interrupted by packet processing and the packet is an attempt to reopen a closed connection, TCP conntrack tries to kill the old entry itself and returns NF_REPEAT to pass the packet through the hook again. This may lead to an endless loop: TCP conntrack repeatedly finds the old entry, but can not kill it itself since destruction is already in progress, but destruction in process context can not complete since TCP conntrack is keeping the CPU busy. Drop the packet in TCP conntrack if we can't kill the connection ourselves to avoid this.

2008-07-09zd1211rw: stop beacons on remove_interfaceLuis Carlos Cobo

2008-07-09rt2x00: Disable synchronization during initializationIvo van Doorn
As soon as init_registers() was called, the rt2400/rt2500 would start raising beacondone interrupts. Since this is highly premature since no beacons were provided yet, we should initialize the synchronization register to 0. This will make all drivers initialize it to 0 regardless if they are raising beacondone interrupts or not, since it only makes sense to have it completely disabled.

2008-07-09rc80211_pid: Fix fast_start parameter handlingMattias Nissler
This removes the fast_start parameter from the rc_pid parameters information and instead uses the parameter macro when initializing the rc_pid state. Since the parameter is only used on initialization, there is no point of making exporting it via debugfs. This also fixes uninitialized memory references to the fast_start and norm_offset parameters detected by the kmemcheck utility. Thanks to Vegard Nossum for reporting the bug.

2008-07-09x86: fix C1E && nx6325 stability problemRafael J. Wysocki
The problems are that, with the ACPI vs timer overring issue _fixed_, after using the box for some time (between several seconds and 1 hour, at random) processes get very high CPU loads (once I've got X using 107% of the CPU, for example) and the system becomes unresponsive, as though there were interrupts lost or something similar.
