Input: psmouse sync. changes
- when a partial packet is received (more than HZ/2 jiffies
has passed since last byte was received) increment
out-of-sync counter. It should help users with KVMs that
reset mice to bare PS/2 protocol but do not send 0xAA 0x00
init sequence - after 'resetafter' bad packets psmouse
will try reconnecting and reestablishing proper protcol.
- change default value for 'resetafter' parameter from
0 (never) to 20.

Input: Add serio_raw driver that binds to serio ports and provides
unobstructed access to the underlying serio port via a char
device. The driver tries to register char device 10,1
(/dev/psaux) first and if it fails goes for dynamically
allocated minor. To bind use sysfs interface:

Input: allow marking some drivers (that don't do HW autodetection)
as manual bind only. Such drivers will only be bound to a
serio port if user requests it by echoing driver name into
port's sysfs driver attribute.

What is the sysfs directory layout, and what do the chosen nodes do?
What design decisions were made when choosing that layout?
Is it so trivial that users don't need any documentation?

I do consider it trivial for now as the only thing that user can do is
"echo" desired driver into serioX/driver to rebind it. The typical node
looks like this:

to match with /proc/bus/input/devices).
Every driver will have a set of custom attributes that will be documented
on one by one basis. Btw, where would you document it? Documentation
directory entry? Something else?

Conceivably one could attempt to document it via module_parm_desc in each
driver, but I presume that won't work for a host of reasons.
So yup, a succinct description in Documentation/input/ would be great.

This patch causes problems on sparc64:
drivers/input/serio/i8042-sparcio.h: In function `i8042_platform_init':
drivers/input/serio/i8042-sparcio.h:103: error: `i8042_reset' undeclared (first use in this function)

drivers/input/serio/i8042.c: At top level:

Which will be fixed by this patch:

due to:

I8042_KBD_IRQ is not a constant on sparc64.
It seems that simply removing that static initialiser will fix
it up, but I assume it was added for some reason, so I'll leave
you to ponder that.

Yes, what you see are leftovers from me missing that fact...

No, removing the initialization is the correct way to fix it. We can
only assign these values after platform init is done.
Sorry about the breakage.

Ok..
