2012-08-27video: tegra: nvmap: fix handle usecount trackingTuomas Tynkkynen
A handle's usecount used to be incremented once during the mmap ioctl, and decremented when the mapping is closed by the kernel. However, that fails if a mapping cloned, for example if the mapping was split due to a munmap, or (presumably) during fork, as the decrement will then happen for each cloned mapping. Therefore increment the usecount when a mapping is opened. Also fix a BUG_ON() that would have caught this bug, if it wouldn't have done the check by checking if the unsigned usecount field is less than zero.

nvhost_3dctx_alloc_common correctly checks the return value of an allocator function, and attempts to perform cleanup. However, this particular allocation API returns ERR_PTR values in case of failure, which then gets passed to the deallocation function, causing a crash. Also, the return value of that allocator API is checked with IS_ERR in some places, and with IS_ERR_OR_NULL in others. For consistency and avoiding surprises if the allocation implementation changes, use IS_ERR_OR_NULL in all places.

nvmap_ioctl_pinop kmalloc's a temporary buffer, whose length is directly given by ioctl parameter from usermode. The total size of the buffer is not checked for overflow, which will cause a kernel panic with some inputs. Also, a sizeof() is applied to wrong type when calculating the amount of bytes to copy from userspace. nvmap_map_into_caller_ptr attempts to validate that the memory range to be mapped is correct, but integer overflow can cause the check to fail. This will lead to mapping wrong pages from the allocated handle later on, when the page fault handler gets called.

Creates a miscdev at /dev/tegra-throughput which gl will use to set a target frame rate. In addition it receives notifications from dc on flip events. On each notification the percentage ratio of the actual frame time to the target frame time is calculated. In subsequent changes this ratio will be reported to other modules as a throughput hint.
