Although the other USB driver directories got taught how use Kconfig and the Makefile to enable the debugging messages enabled by -DDEBUG, the gadget stack was overlooked. This patch remedies that omission, but doesn't update any drivers to remove previous idiosyncracies in this area ... other than the RNDIS code, which defined its own DEBUG() macro in a broken way.

This patch removes controller driver infrastructure which supported the now-removed usb_ep_{alloc,free}_buffer() calls. As can be seen, many of the implementations of this were broken to various degrees. Many didn't properly return dma-coherent mappings; those which did so were necessarily ugly because of bogosity in the underlying dma_free_coherent() calls ... which on many platforms can't be called from the same contexts (notably in_irq) from which their dma_alloc_coherent() sibling can be called. The main potential downside of removing this is that gadget drivers wouldn't have specific knowledge that the controller drivers have: endpoints that aren't dma-capable don't need any dma mappings at all.

Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers. This patch just removes the interface and its users; later patches will remove controller driver support. - This interface is invariably not implemented correctly in the controller drivers (e.g. using dma pools, a mechanism which post-dates the interface by several years). - At this point no gadget driver really *needs* to use it. In current kernels, any driver that needs such a mechanism could allocate a dma pool themselves. Removing this interface is thus a simplification and improvement. Note that the gmidi.c driver had a bug in this area; fixed. Signed-off-by: NDavid Brownell <dbrownell@users.sourceforge.net> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

Cleanups to the pxa2xx_udc code: - Primarily removing unused DMA hooks. - One "sparse" warning removed - Remove some Lubbock-only LED hooks (for debugging) That DMA code was never really completed. It worked, mostly, for IN transfers (to the host) if they were fortuitously aligned, but that code was never fully tested. And it was never coded for OUT transfers (which is where DMA would really help) ... because of chip errata on essentially every chip other than the pxa255, and because of design botches (nothing automated data toggle). So it's effectively been dead code for several years now ... no point in keeping it around.

This patch updates some of the documentation about DMA buffer management for USB, and ways to avoid extra copying. Our understanding of the issues has improved over time. - Most drivers should *avoid* the dma-coherent allocators. There are a few exceptions (like the HID driver). - Some methods are currently commented out; it seems folk writing USB drivers aren't doing performance tuning at that level yet. - Just avoid highmem; there's no good way to pass an "I can do highmem DMA" capability through a driver stack. This is easy, everything already avoids highmem. But it'd be nice if x86_32 systems with much physical memory could use it directly with network adapters and mass storage devices. (Patch, anyone?)

The loop in usb_sg_wait() is structured in a way that makes it hard to tell, when the loop exits, whether or not the last URB submission succeeded. This patch (as928) changes it from a "for" loop to a "while" loop and keeps "i" always equal to the number of successful submissions. This fixes an off-by-one error which can show up when the first URB submission fails. The patch also removes a couple of lines that initialize fields which don't need to be initialized.

Root hubs can't be resumed if their parent controller device is still suspended. This patch (as925) adds a check for that condition in hcd_bus_resume() and prevents it from being treated as a fatal controller failure. ehci-hcd is updated to add the corresponding test. Unnecessary debugging messages are removed from uhci-hcd and dummy-hcd. The error return code from dummy-hcd is changed to -ESHUTDOWN, the same as the others. ohci-hcd doesn't need any changes. Suspend handling in the non-PCI host drivers is somewhat hit-and-miss. This patch shouldn't have any effect on them.

This patch's main bulk aims to make usblp the premier driver for code pillaging once again. The code is as streamlined as possible and is bug-free as possible. The usb-skeleton performs the same function, but is somewhat abstract. The usblp is usb-skeleton which is actually used by many. Since I combed a few small bugs away, this also fixes the small races we had in usblp for a while. For example, now it's possible for several threads to make write(2) calls (sounds silly, but consider a printer for paper record, where every line of text is self-contained and thus it's all right to have them interleaved). Also gone are issues with interrupts using barriers dangerously. This patch makes use of Oliver's anchor, and so it must trail the anchor patch on the way to Linus.

USB: Add URB_FREE_BUFFER flag for freeing the transfer buffer In some cases it is not needed that the driver keeps track of the transfer buffer of an URB.

- Drivers don't call ldisc termios methods. They certainly don't call them the way this one does - remove wrong call - The tty buffer code isn't designed to be abused from IRQ handlers and the new buffering removes the need for the uglies involved - fix them - Style - Remove incorrect baud and change handling for termios changes The driver now has some style, but not a lot - it goes insane if you have two dongles for example as it continues to use global variables for per dongle state.
