* media/video: don't use flush_scheduled_work()Tejun Heo2010-12-244-10/+5
| | | | | | | | | | | | | | | | | | | This patch converts the remaining users of flush_scheduled_work() in media/video. * bttv-input.c and cx23885-input.c don't use workqueue at all. No need to flush. * Make omap24xxcam.c and saa7134-empress.c flush the used work directly. * In fd_defio.c, replace cancel_delayed_work() + flush_scheduled_work() with cancel_delayed_work_sync(). While at it, replace the deprecated cancel_rearming_delayed_work() with cancel_delayed_work_sync(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Mauro Carvalho Chehab <mchehab@infradead.org>
* media/video: explicitly flush request_module workTejun Heo2010-12-246-2/+50
| | | | | | | | | | | | | | | | | Video drivers request submodules using a work during probe and calls flush_scheduled_work() on exit to make sure the work is complete before being unloaded. This patch makes these drivers flush the work directly instead of using flush_scheduled_work(). While at it, relocate request_submodules() call in saa7134_initdev() right right before successful return as in other drivers to avoid failing after the work is scheduled and returning failure without the work still active. This is in preparation for the deprecation of flush_scheduled_work(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Mauro Carvalho Chehab <mchehab@infradead.org>
* ioc4: use static work_struct for ioc4_load_modules()Tejun Heo2010-12-241-20/+9
| | | | | | | | | | | | | There is no reason to dynamically allocate work_struct for ioc4_load_modules(). It makes the code more complex and makes it impossible to flush the work directly. Use static work ioc4_load_modules_work instead and flush it directly on exit. This removes the use of flush_scheduled_work() which is being deprecated.

| * | pci root complex: support for tile architectureChris Metcalf2010-11-242-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change enables PCI root complex support for TILEPro. Unlike TILE-Gx, TILEPro has no support for memory-mapped I/O, so the PCI support consists of hypervisor upcalls for PIO, DMA, etc. However, the performance is fine for the devices we have tested with so far (1Gb Ethernet, SATA, etc.). The <asm/io.h> header was tweaked to be a little bit more aggressive about disabling attempts to map/unmap IO port space. The hacky <asm/pci-bridge.h> header was rolled into the <asm/pci.h> header and the result was simplified. Both of the latter two headers were preliminary versions not meant for release before now - oh well. There is one quirk for our TILEmpower platform, which accidentally negotiates up to 5GT and needs to be kicked down to 2.5GT. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

The infrastructure is present for the TILE-Gx networking drivers (another three source files in the new directory) but for now the the actual tilegx sources are waiting on releasing hardware to initial customers. Note that arch/tile/include/hv/* are "upstream" headers from the Tilera hypervisor and will probably benefit less from LKML review. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

It's basically harmless. Your terminal will be messed up until you type reset. This patch does three things to fix the bug. First, it checks the return value of fb_copy_cmap() in fb_alloc_cmap(). That is enough to fix address the overflow. Second it checks for the integer overflow in fb_set_user_cmap(). Lastly I wanted to cap "cmap->len" in fb_set_user_cmap() much lower because it gets used to determine the size of allocation. Unfortunately no one knows what the limit should be. Instead what this patch does is makes the allocation happen with GFP_KERNEL instead of GFP_ATOMIC and lets the kmalloc() decide what values of cmap->len are reasonable. To do this, the patch introduces a function called fb_alloc_cmap_gfp() which is like fb_alloc_cmap() except that it takes a GFP flag.

This caused 1080p24 mode to not work on AP4EVB. Additionally the notifier chain was also called with the wrong mode. This patch fixes this, by using the X-resolution of the new mode instead of the old one to calculate line length and hands over the correct mode to the notifier chain.
