2009-11-23be2net: remove BUG_ON() when be2net runs out of mccq wrbsSathya Perla
The driver can run out of mccq wrbs when completions don't arrive due to an unresponsive card. This must not hit a BUG_ON(); instead log a msg and return an error. Signed-off-by: Sathya Perla <sathyap@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-11-23pktgen: Fix device name comparesEric Dumazet
Commit e6fce5b916cd7f7f7 (pktgen: multiqueue etc.) tried to relax the pktgen restriction of one device per kernel thread, adding a '@' tag to device names. Problem is we dont perform check on full pktgen device name. This allows adding many time same 'device' to pktgen thread pgset "add_device eth0@0" one session later : pgset "add_device eth0@0" (This doesnt find previous device) This consumes ~1.5 MBytes of vmalloc memory per round and also triggers this warning : [ 673.186380] proc_dir_entry 'pktgen/eth0@0' already registered [ 673.186383] Modules linked in: pktgen ixgbe ehci_hcd psmouse mdio mousedev evdev [last unloaded: pktgen] [ 673.186406] Pid: 6219, comm: bash Tainted: G W 2.6.32-rc7-03302-g41cec6f-dirty #16 [ 673.186410] Call Trace: [ 673.186417] [<ffffffff8104a29b>] warn_slowpath_common+0x7b/0xc0 [ 673.186422] [<ffffffff8104a341>] warn_slowpath_fmt+0x41/0x50 [ 673.186426] [<ffffffff8114e789>] proc_register+0x109/0x210 [ 673.186433] [<ffffffff8100bf2e>] ? apic_timer_interrupt+0xe/0x20 [ 673.186438] [<ffffffff8114e905>] proc_create_data+0x75/0xd0 [ 673.186444] [<ffffffffa006ad38>] pktgen_thread_write+0x568/0x640 [pktgen] [ 673.186449] [<ffffffffa006a7d0>] ? pktgen_thread_write+0x0/0x640 [pktgen] [ 673.186453] [<ffffffff81149144>] proc_reg_write+0x84/0xc0 [ 673.186458] [<ffffffff810f5a58>] vfs_write+0xb8/0x180 [ 673.186463] [<ffffffff810f5c11>] sys_write+0x51/0x90 [ 673.186468] [<ffffffff8100b51b>] system_call_fastpath+0x16/0x1b [ 673.186470] ---[ end trace ccbb991b0a8d994d ]--- Solution to this problem is to use a odevname field (includes @ tag and suffix), instead of using netdevice name.

2009-11-23hw-breakpoints: Check the breakpoint params from perf toolsFrederic Weisbecker
Perf tools create perf events as disabled in the beginning. Breakpoints are then considered like ptrace temporary breakpoints, only meant to reserve a breakpoint slot until we get all the necessary informations from the user. In this case, we don't check the address that is breakpointed as it is NULL in the ptrace case. But perf tools don't have the same purpose, events are created disabled to wait for all events to be created before enabling all of them. We want to check the breakpoint parameters in this case.

2009-11-23perf_events: Restore sanity to scaling landPeter Zijlstra
It is quite possible to call update_event_times() on a context that isn't actually running and thereby confuse the thing. perf stat was reporting !100% scale values for software counters (2e2af50b perf_events: Disable events when we detach them, solved the worst of that, but there was still some left). The thing that happens is that because we are not self-reaping (we have a caring parent) there is a time between the last schedule (out) and having do_exit() called which will detach the events. This period would be accounted as enabled,!running because the event->state==INACTIVE, even though !event->ctx->is_active. Similar issues could have been observed by calling read() on a event while the attached task was not scheduled in. Solve this by teaching update_event_times() about ctx->is_active.

2009-11-23ARM: MX3: fix CPU revision number detectionDaniel Mack
The macro mx31_revision() used to take the global variable system_rev to determine the CPU revision number. However, this number is expected to be set by the bootloader and is usually zero (at least on my MX31 based boards here). More than that, it is usually taken to identify the board's revision, not the CPU's. Fix that by reading the the CPU's SREV register instead. Right now, mx31_read_cpu_rev() is called from mx31_clocks_init() which is admittedly not a good place for it. However, we need to enable the IIM clock first, and the clock code also has conditional code that depends on mx31_revision() returning the right thing.
