2009-07-05drivers/net/smsc911x.c: Fix resource size off by 1 errorJulia Lawall
The call resource_size(res) returns res->end - res->start + 1 and thus the second change is semantics-preserving. res_size is then used as the second argument of a call to request_mem_region, and the memory allocated by this call appears to be the same as what is released in the two calls to release_mem_region. So the size argument for those calls should be resource_size(size) as well. Alternatively, in the second call to release_mem_region, the second argument could be res_size, as that variable has already been initialized at the point of this call. The problem was found using the following semantic patch: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) @@ struct resource *res; @@ - res->end - res->start + BAD(resource_size(res)) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2009-07-05tun: Fix device unregister raceHerbert Xu
It is currently possible for an asynchronous device unregister to cause the same tun device to be unregistered twice. This is because the unregister in tun_chr_close only checks whether __tun_get(tfile) != NULL. This however has nothing to do with whether the device has already been unregistered. All it tells you is whether __tun_detach has been called. This patch fixes this by using the most obvious thing to test whether the device has been unregistered. It also moves __tun_detach outside of rtnl_unlock since nothing that it does requires that lock. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

There are apparently some units with a DiBcom demodulator which could be supported by one of the dib7000 modules - but this is not implemented in the cx18 driver (yet). Due to lack of porgramming details for the MT352 and the mt352 module requiring a "demod_init" function, a "firmware" must be obtained and loaded to get DVB-T working for Yuan MPC-718 cards with an MT352.

2009-07-04intel-iommu: Don't use identity mapping for PCI devices behind bridgesDavid Woodhouse
Our current strategy for pass-through mode is to put all devices into the 1:1 domain at startup (which is before we know what their dma_mask will be), and only _later_ take them out of that domain, if it turns out that they really can't address all of memory. However, when there are a bunch of PCI devices behind a bridge, they all end up with the same source-id on their DMA transactions, and hence in the same IOMMU domain. This means that we _can't_ easily move them from the 1:1 domain into their own domain at runtime, because there might be DMA in-flight from their siblings. So we have to adjust our pass-through strategy: For PCI devices not on the root bus, and for the bridges which will take responsibility for their transactions, we have to start up _out_ of the 1:1 domain, just in case. This fixes the BUG() we see when we have 32-bit-capable devices behind a PCI-PCI bridge, and use the software identity mapping. It does mean that we might end up using 'normal' mapping mode for some devices which could actually live with the faster 1:1 mapping -- but this is only for PCI devices behind bridges, which presumably aren't the devices for which people are most concerned about performance.

2009-07-04intel-iommu: Use iommu_should_identity_map() at startup time too.David Woodhouse
At boot time, the dma_mask won't have been set on any devices, so we assume that all devices will be 64-bit capable (and thus get a 1:1 map). Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2009-07-04video: sm501fb: Early initialization of mm_lock mutex.Paul Mundt
Commit 537a1bf059fa312355696fa6db80726e655e7f17 (fbdev: add mutex for fb_mmap locking) introduces a ->mm_lock mutex for protecting smem assignments. Unfortunately in the case of sm501fb these happen quite early in the initialization code, well before the mutex_init() that takes place in register_framebuffer(), leading to: Badness at kernel/mutex.c:207 Pid : 1, Comm: swapper CPU : 0 Not tainted (2.6.31-rc1-00284-g529ba0d-dirty #2273) PC is at __mutex_lock_slowpath+0x72/0x1bc PR is at __mutex_lock_slowpath+0x66/0x1bc ... matroxfb appears to have the same issue and has solved it with an early mutex_init(), so we do the same for sm501fb.
