* [WATCHDOG] bfin: fix max timeout calculationMike Frysinger2010-02-211-6/+7
| | | | | | | | | | | Relying on overflow/wrap around isn't exact because if you wrap far enough, you get back to "valid" values.

| * V4L/DVB: bttv: Move I2C IR initializationJean Delvare2010-02-193-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move I2C IR initialization from just after I2C bus setup to right before non-I2C IR initialization. This avoids the case where an I2C IR device is blocking audio support (at least the PV951 suffers from this). It is also more logical to group IR support together, regardless of the connectivity.

| * V4L/DVB: Video : pwc : Fix regression in pwc_set_shutter_speed caused by bad ↵Martin Fuzzey2010-02-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constant => sizeof conversion. Regression was caused by my commit 6b35ca0d3d586b8ecb8396821af21186e20afaf0 which determined message size using sizeof rather than hardcoded constants. Unfortunately pwc_set_shutter_speed reuses a 2 byte buffer for a one byte message too so the sizeof was bogus in this case. All other uses of sizeof checked and are ok.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I'm trying to fix it on the GCC side (PR43007), but the module is quite stupid in using ULL constants to operate on u32 values: static int apply_frontend_param (struct dvb_frontend* fe, struct dvb_frontend_parameters *param) { ... static const u32 ppm = 8000; u32 spi_bias; ... spi_bias *= 1000ULL; spi_bias /= 1000ULL + ppm/1000; which causes current GCC 4.5 to emit calls to __udivdi3 for i?86 again. This patch fixes this issue.

We shouldn't allow the user to destroy connections by removing the module. We should force the user to destroy each connection and then the module can be removed. This patch makes it so a refrerence count on the module is taken each time a fcoe_interface is created. The reference count is dropped when the fcoe_interface is destroyed. This makes it so that module_exit() doesn't get called unless all fcoe_interfaces have been destroyed. This patch leaves the removal of interfaces in the module_exit routine so that if the user does a 'rmmod -f' we'll clean everything up before removing the module. The module_put line was put before the out_putdev goto line because we should only be decrementing the reference count if a fcoe_interface is actually destroyed. If we can't find the netdev or the fcoe_interface then it's assumed that something else has destroyed the fcoe_interface and it would have decremented the reference count at that time.

The old governor had the accidental behavior that if a non-working state was chosen too many times, it would end up falling back to C1. The new governor works differently and this accidental behavior is no longer there; the result is a high temperature on these two machines. This patch adds these 2 machines to the DMI table for C state anomalies; by just not using C2 both these machines are better off (the TSC can be used instead of the pm timer, giving a performance boost for example).

We passed that interface a stack variable, which is kmemdup'ed and assigned to the device's platform_data pointer. Unfortunately, whatever random garbage is in the stack variable gets coped during the kmemdup, and that leads to broken behavior. Explicitly zero out the structure before passing it to the API.

This patch rework the handling and properly separate each case. So when you get ib we set the ib as non free and fence status doesn't matter. Fence become active (ie has a meaning for the ib code) once the ib is scheduled or free. This patch also get rid of the alloc bitmap as it was overkill, we know go through IB pool list like in a ring buffer as the oldest IB is the first one the will be free.
