Let the special baudrate processing on the tty layer. Also remove set/get_special_rate ioctls introduced in commit f64c84a1, since it is no longer needed. Signed-off-by:

Both of them may be called directly from the code, don't add special code and variables and schedule a work for them. Signed-off-by:

- Cy_EVENT_OPEN_WAKEUP is simple wake_up - Cy_EVENT_HANGUP is wake_up + tty_hangup, which schedules its own work - Cy_EVENT_WRITE_WAKEUP is tty_wakeup which may be called directly too Signed-off-by:

- tty_hangup schedules a bottomhalf itself, tty_wakeup doesn't need it - call the CD code (part of work handler previously) directly from the code (it wakes somebody up or calls tty_hangup at worse) Signed-off-by:

tty_hangup schedules a work for hangup itself, no need to do it in the driver. Signed-off-by:

There is no need to schedule a bottomhalf for either of them. One is fast and the another schedules a bottomhalf itself. Signed-off-by:

Use cmpxchg_u32 and cmpxchg_u64 for cmpxchg_local and cmpxchg64_local. For other type sizes, use the new generic cmpxchg_local (disables interrupt). Change: Since the header depends on local_irqsave/local_irqrestore, it must be included after their declaration. Actually, being below the #include <linux/irqflags.h> should be enough, and on sparc64 it is included at the beginning of system.h. So it makes sense to move it up for sparc64. Signed-off-by:

Add a local processor version of cmpxchg for ppc. Implements __cmpxchg_u32_local and uses it for 32 bits cmpxchg_local. It uses the non NMI safe cmpxchg_local_generic for 1, 2 and 8 bytes cmpxchg_local. Signed-off-by:

This patch is for Mathieu Desnoyers's include/asm-m32r/local.h.

the #endif /* CONFIG_SMP */ should cover the default condition, or it may cause bad parameter to be silently missed. To make it work correctly, we have to remove the ifdef CONFIG SMP surrounding __xchg_called_with_bad_pointer declaration. Thanks to Adrian Bunk for detecting this. Signed-off-by:

Add __xchg_local, xchg_local (define), __cmpxchg_local_u32, __cmpxchg_local, cmpxchg_local(macro). cmpxchg_local and cmpxchg64_local will use the architecture specific __cmpxchg_local_u32 for 32 bits arguments, and use the generic __cmpxchg_local_generic for 8, 16 and 64 bits arguments.

Add the primitives cmpxchg_local, cmpxchg64 and cmpxchg64_local to ia64. They use cmpxchg_acq as underlying macro, just like the already existing ia64 cmpxchg(). Changelog: ia64 cmpxchg_local coding style fix Quoting Keith Owens: As a matter of coding style, I prefer #define cmpxchg_local cmpxchg #define cmpxchg64_local cmpxchg64 Which makes it absolutely clear that they are the same code. With your patch, humans have to do a string compare of two defines to see if they are the same. Note cmpxchg is *not* a performance win vs interrupt disable / enable on IA64. Signed-off-by:

Use the new generic cmpxchg_local (disables interrupt) for 8, 16 and 64 bits cmpxchg_local. Use the __cmpxchg_u32 primitive for 32 bits cmpxchg_local. Note that cmpxchg only uses the __cmpxchg_u32 or __cmpxchg_u64 and will cause a linker error if called with 8 or 16 bits argument. Signed-off-by:
