This reverts commit b1c43f82. It was broken in so many ways, and results in random odd pty issues. It re-introduced the buggy schedule_work() in flush_to_ldisc() that can cause endless work-loops (see commit a5660b41: "tty: fix endless work loop when the buffer fills up"). It also used an "unsigned int" return value fo the ->receive_buf() function, but then made multiple functions return a negative error code, and didn't actually check for the error in the caller. And it didn't actually work at all. BenH bisected down odd tty behavior to it: "It looks like the patch is causing some major malfunctions of the X server for me, possibly related to PTYs. For example, cat'ing a large file in a gnome terminal hangs the kernel for -minutes- in a loop of what looks like flush_to_ldisc/workqueue code, (some ftrace data in the quoted bits further down). ... Some more data: It -looks- like what happens is that the flush_to_ldisc work queue entry constantly re-queues itself (because the PTY is full ?) and the workqueue thread will basically loop forver calling it without ever scheduling, thus starving the consumer process that could have emptied the PTY." which is pretty much exactly the problem we fixed in a5660b41. Milton Miller pointed out the 'unsigned int' issue.

Commit e66eed65 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, which uncovered several cases that had apparently relied on that rather obscure header file dependency. So this fixes things up a bit, using grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]') grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]') to guide us in finding files that either need <linux/prefetch.h> inclusion, or have it despite not needing it. There are more of them around (mostly network drivers), but this gets many core ones.

This driver allows userspace to access the data processing FPGAs on the OVRO CARMA board. It has two modes of operation: 1) random access This allows users to poke any DATA-FPGA registers by using mmap to map the address region directly into their memory map. 2) correlation dumping When correlating, the DATA-FPGA's have special requirements for getting the data out of their memory before the next correlation. This nominally happens at 64Hz (every 15.625ms). If the data is not dumped before the next correlation, data is lost. The data dumping driver handles buffering up to 1 second worth of correlation data from the FPGAs. This lowers the realtime scheduling requirements for the userspace process reading the device.

The PTI (Parallel Trace Interface) driver directs trace data routed from various parts in the system out through an Intel Penwell PTI port and out of the mobile device for analysis with a debugging tool (Lauterbach or Fido). Though n_tracesink and n_tracerouter line discipline drivers are used to extract modem tracing data to the PTI driver and other parts of an Intel mobile solution, the PTI driver can be used independent of n_tracesink and n_tracerouter. You should select this driver if the target kernel is meant for an Intel Atom (non-netbook) mobile device containing a MIPI P1149.7 standard implementation.

When certain technologies shutdown their interface without waiting for the acknowledgement from the chip. The receive_buf from the TTY would be invoked a while after the relevant technology is unregistered. This patch introduces a new flag "is_registered" which maintains the state of protocols BT, FM or GPS and thereby removes the need to clear the protocol data from ST when protocols gets unregistered. This fixes corner cases when HCI RESET is sent down from bluetooth stack and the receive_buf is called from tty after 250ms before which bluetooth would have unregistered from the system. OR - when FM application decides to close down the device without sending a power-off FM command resulting in some RDS data or interrupt data coming in after the driver is unregistered.

To fasten the process of firmware download, the chip allows disabling of the command complete event generation from host. In these cases, only few very essential commands would have the command complete events and hence the wait associated with them.
