linux 2.5.25

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.

You could go by the CPU choice that already exists:

386      -->  100
486      -->  200
Pentium  -->  400
PPro     -->  800

P-III,P4 --> 1600

Found a few typos in the input changes. Fixup patch attached.

OK. I assumed that Config.in was the authoritative source, and Config.help should match. Looks like (based on the Makefile) that I probably should have changed it to be CONFIG_GAMEPORT_EMU10K1 in the Config.in. In fact, that driver won't ever be built with vanilla 2.5.25, with or without the previous patch

BK already has the previous change applied, so this in an incremental diff:

<bk text>
EMU10K1 build fix

Revert the CONFIG_INPUT_EMU10K1 change to drivers/input/gameport/Config.help, and change drivers/input/gameport/Config.in to use CONFIG_GAMEPORT_EMU10K1 </bk text>

Did the LVM guys (are you listening?) tell anything if they were about to go fix the current 2.5 LVM breakage? Or does EVMS work on 2.5 instead?

I'll say this yet again:

Heinz Mauelshagen is maintaining LVM1.0.x on 2.4 kernels. This is for bug fixes only, no new features will be added.

Alasdair Kergon, Patrick Caulfield and myself are working on the more generic device-mapper driver for both 2.4/2.5. Initially we have concentrated on 2.4, this driver is now very stable IMO (I would certainly trust my data to it in preference to LVM1).

I will post a URL to the 2.5 patch at some point this week.

There is no intention to maintain the broken design that is LVM1 in the 2.5 series - we do not have the spare resources to waste.

- Joe

All right. So how about removing it from the tree? It's broken; it won't be fixed; it's abandoned by maintainers (and $DEITY witness, there is a lot of very good reasons for that); there's nobody who would be able and willing to pick it. What's the point of keeping the damn thing in the tree?

Could you (or Heinz) submit the patch removing it from 2.5?

...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);

t.

The following patch does the following:

1. Make airo include tqueue.h, which is needed to make this driver compile at all again.

2. Adjust aztcd.c and sonycd535.c to the recent end_request() signature changes.

The patch is against 2.5.24, but still applies cleanly on top of 2.5.25.
