...the program can still run, any idea ? Error in optim(c(0.08, 0.04, 1), f, NULL, method = "L-BFGS-B", lower = c(0, : L-BFGS-B needs finite values of 'fn' Thank you for any information on these two problems.

Make use of the devm_drm_dev_alloc() API to bind the lifetime of nouveau_drm structure to the drm_device. This is important because a reference to nouveau_drm is accessible from drm_device, which is provided to a number of DRM layer callbacks that can run after the deallocation of nouveau_drm currently occurs.

Recent rework of the virtio_mmio probe/remove paths balanced a devm_ioremap() with an iounmap() rather than its devm variant. This ends up corrupting the devm datastructures, and results in the following boot-time splat on arm64 under QEMU 2.9.0: [ 3.450397] ------------[ cut here ]------------ [ 3.453822] Trying to vfree() nonexistent vm area (00000000c05b4844) [ 3.460534] WARNING: CPU:

This patch lets interrupt handler functions have their natural type (ie. exactly match the data pointer type); for transition it allows the old irq_handler_t type as well. To do this it uses a gcc extension, cast-to-union, which allows a type to be cast to any type within the union. When used in a wrapper macro, it's a simple way of allowing one of several types. (Some drivers now need to

...I have plotted using image.plot(), filled.contour() or image(). I would like to overplot this image with some contour lines of mixed layer depth values(same size matrix). How can I do this?

Compared to todays PDAs the GameBoy Advance (GBA) is low spec. it has a 16MHz ARM7tdmi RISC processor. 32-bit but it can handle 16-bit instructions in a mode that resembles "bytecode" (a 32-bit instruction is executed using a 16-bit instruction). I got a feeling that the GBA would need a FPU. For more information on the GBA visit this info page:

I think not. In virtio_pci_common, vp_dev is allocated by kzalloc so a kfree is needed. Here vm_dev is allocated by devm_kmalloc which is "automatically freed on driver detach" from the comment (drivers/base/devres.c:769).

Also, you would be sattisfied with the narrowband decoding because the GBA sound quality isn't very good, however, that depends greatly on what you're going to do with speex on a GBA.... (an RPG with audio dialogs? ;-)) also, using a DSP in a GBA Cartridge sounds like overkill to me, however, that depends greatly on what are you developing and what's your target audience....
