2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-06-25V4L/DVB (4057): Cx88: IR remote support for DTV2000HMalcolm Valentine
Adds support for the Y0400052 remote supplied with this card. In addition to adding a number of buttons to the current winfast definition, it enables all the keys currently masked out with #ifdef 0. It is supplied separately as it remaps two keys from the current definition, The teletext button now sends KEY_TEXT instead of KEY_SUBTITLE, as that keycode is used by the subtitle button. KEY_BACK was changed to KEY_LAST to group it with KEY_NEXT. Other then that the keys don't overlap, so this should support several different versions of the Leadtek remotes.

2005-10-30[PATCH] fix missing includesTim Schmielau
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-09-05[PATCH] I2C: Kill i2c_algorithm.id (6/7)Jean Delvare
In theory, there should be no more users of I2C_ALGO_* at this point. However, it happens that several drivers were using I2C_ALGO_* for adapter ids, so we need to correct these before we can get rid of all the I2C_ALGO_* definitions. Note that this also fixes a bug in media/video/tvaudio.c: /* don't attach on saa7146 based cards, because dedicated drivers are used */ if ((adap->id & I2C_ALGO_SAA7146)) return 0; This test was plain broken, as it would succeed for many more adapters than just the saa7146: any those id would share at least one bit with the saa7146 id. We are really lucky that the few other adapters we want this driver to work with did not fulfill that condition.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
