This flag is a NOOP and can be removed now. Signed-off-by: Yong Zhang Signed-off-by: Dmitry Torokhov

input: hp680_ts_input: ctrl_in/outX to __raw_read/writeX conversion.

2010-10-27T06:25:42Z

The ctrl_xxx routines are deprecated, switch over to the __raw_xxx versions. Signed-off-by: Paul Mundt

Input: hp680_ts_input - use cancel_delayed_work_sync()

2010-10-18T04:12:00Z

Make hp680_ts_init/exit() call cancel_delayed_work_sync() instead of calling cancel_delayed_work() followed by flush_scheduled_work(). This is to prepare for the deprecation and removal of flush_scheduled_work(). Signed-off-by: Tejun Heo Signed-off-by: Dmitry Torokhov

get rid of input BIT* duplicate defines

2007-10-19T18:53:42Z

get rid of input BIT* duplicate defines use newly global defined macros for input layer. Also remove includes of input.h from non-input sources only for BIT macro definiton. Define the macro temporarily in local manner, all those local definitons will be removed further in this patchset (to not break bisecting). BIT macro will be globally defined (1< Cc: Acked-by: Jiri Kosina Cc: Acked-by: Marcel Holtmann Cc: Acked-by: Mauro Carvalho Chehab Cc: Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

sh: Cleanup board header directories.

2006-10-19T07:30:32Z

Now with the ide.h mess sorted out, most of these boards don't need their own directory. Move the headers out, and update the driver paths. Signed-off-by: Paul Mundt

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

2006-10-05T14:10:12Z

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t. Signed-Off-By: David Howells (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
