[PATCH] ftdi_sio: add support for more FTDI based JTAG adaptors
There are more devices similar to the Olimex JTAG adaptor, in that the first
port of the FT2232C is used for JTAG, and only the second port is available as
UART.
I have thus renamed ftdi_olimex_{probe,quirk} to ftdi_jtag_{probe,quirk} and
added vendor/product ID's for the OpenMoko Neo1973 Debug Board as well as the
OOCDlink device.
I've also updated the KERN_INFO message sent to userspace to remove the word
'olimex' and an extra '\n' that was causing an empty line in dmesg.

I work with a group of people on a free home automation tool called
FHEM. Some of the users own more than one USB-serial device by ELV. The
ftdi_sio driver has most of the ELV devices disabled by default and
needs to be re-enabled every time you get a new kernel. Additionally a
new device (EM 1010 PC - enegry monitor) is missing in the list.
Currently our users have to follow the instructions we provide at
http://www.koeniglich.de/fhem/linux.html ... However, to some users it
is too complicated to compile their own kernel module.
We are aware that you can specify one additional device using the
vendor/product option of the module. But lot's of users own more than
one device.

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.
