2008-10-13ide: add a driver-wide debugging macroBorislav Petkov
Add __ide_debug_log() debugging macro which is controlled by drive->debug_mask. The macro has to have the macro DRV_NAME defined in each driver before use. Also, add different debugging levels depending on the functionality debugged. Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-10-13vfs: Use const for kernel parser tableSteven Whitehouse
This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then.

The parameters also help simplify devpts implementation.

2008-10-13tty: More driver operationsAlan Cox

2008-10-13tty: shutdown methodAlan Cox
Right now there are various drivers that try to use tty->count to know when they get the final close. Aristeau Rozanski showed while debugging the vt sysfs race that this isn't entirely safe. Instead of driver side tricks to work around this introduce a shutdown which is called when the tty is being destructed. This also means that the shutdown method is tied into the refcounting. Use this to rework the console close/sysfs logic. Remove lots of special case code from the tty core code. The pty code can now have a shutdown() method that replaces the special case hackery in the tree free up paths.

2008-10-13tty: usb-serial krefsAlan Cox
Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky.

2008-10-13tty: Add termioxAlan Cox
We need a way to describe the various additional modes and flow control features that random weird hardware shows up and software such as wine wants to emulate as Windows supports them. TCGETX/TCSETX and the termiox ioctl are a SYS5 extension that we might as well adopt. This patches adds the structures and the basic ioctl interfaces when the TCGETX etc defines are added for an architecture. Drivers wishing to use this stuff need to add new methods.

2008-10-13tty: Cris has a nice RS485 ioctl so we should steal itAlan Cox
JP Tosoni observed: "About a RS485 ioctl: could you consider the attached files which are already in the Linux kernel (in include/asm-cris). They define a TIOCSERSETRS485 (ioctl.h), and the data structure (rs485.h) with allows to specify timings. Sounds just like what we want ?" and he's right: sort of. Rework the structure to use flag bits and make the time delay a fixed sized field so we don't get 32/64bit problems. Add the ioctls to x86 so that people know what to add to their platform of choice.

2008-10-13Automatic MODULE_ALIAS() for DMI match tables.David Woodhouse
This makes modpost handle MODULE_DEVICE_TABLE(dmi, xxxx). I had to change the string pointers in the match table to char arrays, and picked a size of 79 bytes almost at random -- do we need to make it bigger than that? I was a bit concerned about the 'bloat' this introduces into the match tables, but they should all be __initdata so it shouldn't matter too much. (Actually, modpost does go through the relocations and look at most of them; it wouldn't be impossible to make it handle string pointers -- but doesn't seem to be worth the effort, since they're __initdata).

Commit 4a701737 ("x86: move prefill_possible_map calling early, fix") is the wrong fix: prefill_possible_map() needs to be available even when CONFIG_HOTPLUG_CPU is not set. A followon patch will do that. Fix this correctly by making prefill_possible_map() available even when CONFIG_HOTPLUG_CPU is not set. The function is needed so that the number of possible CPUs can be determined. Tested on uniprocessor machine with CPU hotplug disabled.
