2.5.25: 2 problems found

1) Options under Input Device Support and under Character Devices: Mice
are duplicates from a user's point of view. Fortunately they have different 
names (CONFIG_PSMOUSE vs CONFIG_MOUSE_PS2).
Unfortunately they both seem to be used...did a recursive grep.


2)  This is a compilation error, which has been in 2.5 since 3 kernels ago or 
so. Reported twice on LKML by me, as well as another person. No reply. 

mpparse.c: In function `mp_parse_prt':

Hi all,
            some small other problems.

make dep claims that i2c-old.h is missing. (also in 2.5.24, not tested 
in other versions)

The input api PS/2 mouse driver is meant to replace the old driver which
is in pc_keyb.c. Unfortunely most keyboard drivers are based around
pc_keyb.c so it has to stay for now. Plus the console system is designed
around pc_keyb.c. This will also change as the console system is migrated
toward the input api. So to any keyboard maintainers please port your
drivers over to the input api before they break when the console system
breaks.

...and a way that scales better when naming large numbers of disks than
disk_name()'s stuff like:
     sprintf(buf, "sd%c%c", 'a' + unit / 26, 'a' + unit % 26);

You could go by the CPU choice that already exists:

386      -->  100
486      -->  200
Pentium  -->  400
PPro     -->  800
P-III,P4 --> 1600

linux 2.5.25

[Linus Torvalds]

More merges all over the map - ppc, scsi, USB, kbuild, input drivers etc.

And both Al and Andrew have been busy again.

This also introduces the support for non-100 Hz internal kernel times on
x86, while still exporting the old interface to user space (ie anybody who
exported raw jiffies before should be exporting "clock_t", which on x86
continues to be a 100 Hz clock, regardless of whatever the internal kernel
frequency is).

Right now the x86 timer frequency is set to 1kHz, but that's just another 
random number. It could be a config option if people really care, but I'd 
rather just have people argue for or against specific internal frequencies 
and we'll find something most people are happy with. It's easy to change 
without user space even noticing now.

The other thing that we should sort out eventually is the unified naming
for disk devices, now that both IDE and SCSI are starting to have some
support for driverfs.  Let's make sure that we _can_ have sane ways of
accessing a disk, without having to care whether it is IDE or SCSI or
anything else.
