[PATCH] pcmcia: conf.ConfigBase and conf.Present consolidation

2006-12-05T01:12:02+00:00

struct pcmcia_device *p_dev->conf.ConfigBase and .Present are set in almost all PCMICA driver right at the beginning, using the same calls but slightly different implementations. Unfiy this in the PCMCIA core. Includes a small bugfix ("drivers/net/pcmcia/xirc2ps_cs.c: remove unused label") from and Signed-off-by Adrian Bunk Signed-off-by: Dominik Brodowski

[PATCH] pcmcia: IDs for Elan serial PCMCIA devcies

2006-12-05T01:09:19+00:00

Add IDs for Elan serial PCMCIA devices. In addition, move the pdaudio_cf driver from matching based on manf_id and card_id to the more specific prod_id1 and prod_id2 to avoid false positives. Signed-off-by: Tony Olech Signed-off-by: Dominik Brodowski

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

2006-10-05T14:10:12+00:00

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)

[ALSA] Memory leak in sound/pcmcia/pdaudiocf/pdaudiocf.c

2006-07-12T18:07:23+00:00

if one of the first three CS_CHECKS fails, we goto cs_failed: In this case parse we donr kfree() parse. Since the the last three CS_CHECKS might also fail, i moved the kfree() below all the CS_CHECKs and added one in the error path.
